An RV slide creeps out after closing when its drive system cannot hold the room securely in the retracted position. Hydraulic slides commonly lose pressure through a leaking valve or cylinder seal, while electric slides may move because of a weak motor brake, worn gears, loose cables, or incomplete retraction.
In this guide, I will help you identify your slide system, narrow down the cause, secure the room safely, and decide whether you can handle the repair yourself.
Key Takeaways
- A properly closed RV slide should not slowly move outward.
- Hydraulic creep usually involves internal fluid or pressure bypass.
- Electric slide creep often points to brake, gear, or cable problems.
- One-sided movement may indicate misalignment or synchronization trouble.
- Marking the slide position helps confirm actual movement.
- Never tow while a slide is visibly moving outward.
- Travel locks provide temporary security but do not fix the cause.
- Complex hydraulic and structural repairs need professional inspection.
Is It Normal for an RV Slide to Move After Closing?
A properly retracted RV slide should remain firmly seated against the exterior wall. You may notice the rubber seals relaxing slightly after the motor or pump stops, but the room itself should not continue moving outward.
The easiest way to tell the difference is to watch the exterior flange. If only the rubber seal changes shape, the room may still be secure. However, if the flange separates from the wall, the painted edge moves, or the gap increases, you are dealing with actual slide creep.
Movement becomes more concerning when one corner opens farther than another. That usually suggests uneven cable tension, motor synchronization trouble, gear wear, or room misalignment.
You should also pay close attention to movement during travel. Road vibration can make a weak holding mechanism much worse. A slide that moves outward while towing should be treated as a safety issue.
How RV Slide-Out Systems Stay Closed
Different slide systems use different methods to hold the room closed. Identifying your system will prevent unnecessary adjustments and help you inspect the correct components.
Hydraulic Slide-Out Systems
Hydraulic slides use pressurized fluid to move one or more cylinders. A pump sends fluid through directional valves, hoses, and fittings to extend or retract the room.
Once the slide closes, the hydraulic valves and internal cylinder seals should prevent fluid movement. If fluid slips past a valve or piston seal, pressure drops and the room may slowly creep outward.
Hydraulic systems are common on larger fifth wheels and motorhomes. One pump may operate several slides, landing gear, or leveling jacks.
Electric Rack-and-Pinion Systems
Rack-and-pinion slides use an electric motor, gearbox, drive shaft, and toothed rails. The motor turns the gears, which move the slide along its tracks.
The motor brake, gearbox resistance, and gear engagement hold the room closed. Worn gears, loose couplers, or a weak motor brake may allow backward movement.
Schwintek and In-Wall Slide Systems
An in-wall slide normally has a motor and track assembly on each side. Both motors must move together to keep the room square.
If one motor stops early or loses synchronization, one side may remain slightly open. That uneven position can look like creep or allow the room to shift farther.
Cable-Driven Slide Systems
Cable-driven slides use cables, pulleys, brackets, and a central drive system. Balanced cable tension pulls the room inward and keeps it properly aligned.
Loose, stretched, or uneven cables can leave one corner less secure. The room may then move outward as the RV shifts or settles.
Hydraulic vs. Electric Slide Creep Symptoms
The way your slide moves often provides useful diagnostic clues. Use the table below to determine which components deserve attention first.
| Symptom | Common on Hydraulic Slides | Common on Electric Slides | Possible Cause |
| Entire room slowly moves outward | Yes | Sometimes | Valve bypass, cylinder bypass, or weak brake |
| One side moves farther outward | Sometimes | Yes | Misalignment, synchronization, gear, or cable problem |
| Movement begins after the pump stops | Yes | No | Hydraulic pressure loss or trapped air |
| Room can be pushed outward manually | Uncommon | Yes | Disengaged or failed motor brake |
| Hydraulic fluid appears around fittings | Yes | No | Hose, fitting, manifold, or cylinder leak |
| Clicking or grinding occurs | No | Yes | Worn gears, coupler, motor, or drive shaft |
| Creep worsens during towing | Yes | Yes | Holding-system failure and road vibration |
| Slide stops before compressing the seals | Sometimes | Yes | Weak voltage, obstruction, or limit problem |
These symptoms can guide your inspection, but they do not confirm a failed part by themselves. Several different problems can create similar movement.
What Causes a Hydraulic RV Slide to Creep Out?
Hydraulic creep happens when fluid moves through a component that should remain sealed. The problem may be inside the valve block, hydraulic cylinder, hose system, or manual override.
A Leaking Hydraulic Solenoid Valve
The pump manifold contains valves that direct fluid toward the correct side of each cylinder. When you release the slide switch, those valves should close and hold pressure.
A worn, contaminated, or damaged valve may allow fluid to pass internally. The retract side then loses pressure, allowing the slide to drift outward.
You may not see any fluid on the ground because the leakage happens inside the manifold. The slide may retract normally and then begin moving again several minutes later.
Common signs include:
- The entire room creeps outward evenly.
- No external fluid leak is visible.
- Reclosing the room only helps temporarily.
- Other hydraulic functions still operate normally.
- The problem becomes worse over time.
A valve can also stick because of contamination. However, you should not remove or disassemble manifold components without system-specific instructions.
A Worn Internal Cylinder Seal
A hydraulic cylinder contains a piston with seals that separate both sides. When those seals wear, fluid can bypass the piston internally.
The cylinder may remain completely dry on the outside. This often confuses owners because there is no obvious leak to inspect.
Internal bypass allows the room’s weight to push the piston backward. The slide may slowly creep outward even though the pump, hoses, and fittings look normal.
A technician may need to isolate the cylinder and perform a pressure test. Cylinder rebuilding or replacement is often necessary when internal seals fail.
Trapped Air in the Hydraulic Lines
Hydraulic fluid does not compress easily, which helps it hold steady pressure. Air bubbles compress much more readily and can create a soft holding condition.
Air commonly enters the system after:
- A hydraulic hose replacement
- Cylinder replacement or rebuilding
- Running the reservoir too low
- Repairing an external leak
- Opening the manifold or pump
- Operating the slide with low fluid
Cycling the slide may purge a small amount of air on some systems. However, repeatedly operating a low-fluid system can damage the pump.
Always confirm the correct bleeding procedure before cycling the room repeatedly.
A Loose Manual Override Valve
Many hydraulic systems include manual override screws or release valves. These allow the slide to move when the pump cannot operate.
If an override remains slightly open, hydraulic pressure may bypass the normal holding circuit. The slide can retract but fail to stay closed.
This problem sometimes appears after manual operation, pump service, or emergency retraction. Dirt around the valve seat may also prevent complete sealing.
Check that the override is returned to its normal operating position. Do not overtighten it because the valve or sealing surface may become damaged.
Low or Incorrect Hydraulic Fluid
Low fluid can allow air to enter the pump and hydraulic lines. It may also prevent the slide from completing a firm retraction cycle.
Before adding fluid, determine the correct slide and jack positions. Reservoir level changes significantly as cylinders extend and retract.
Overfilling the reservoir can create leaks when the cylinders return fluid. Using the wrong fluid may also affect seals, valves, and pump performance.
Check the label on the reservoir, pump, or owner documentation. Never assume every RV hydraulic system uses the same fluid.
An External Hose, Fitting, or Manifold Leak
An external leak can reduce pressure on the retract side. Even a slow seep may eventually allow noticeable room movement.
Inspect these areas carefully:
- Pump reservoir
- Manifold connections
- Hose crimps
- Threaded fittings
- Hydraulic cylinders
- Hose routing points
- Areas beneath the slide
- Leveling or landing gear connections
Look for wetness, oily dirt, drips, and low reservoir levels. A damaged hydraulic hose should be replaced rather than patched with household sealants.
A Damaged Hydraulic Check Valve
Some systems use check valves to prevent fluid from moving backward. Debris, worn seals, or internal damage may stop a valve from seating completely.
A failing check valve can produce symptoms similar to solenoid leakage. The slide may operate normally but fail to remain fully retracted.
Valve testing often requires hydraulic knowledge and proper pressure equipment. This is usually a job for an experienced RV technician.
What Causes an Electric RV Slide to Creep Out?
Electric slides rely on motors, brakes, gears, cables, and synchronized tracks. When one of those components loses holding strength, the room may gradually move outward.
A Disengaged Motor Brake
Some slide motors have a manual brake release or disengagement lever. This feature allows manual operation during an electrical failure.
If the lever remains in the released position, the motor may freewheel. The room’s weight and road vibration can then pull the slide outward.
Check the motor area for a brake lever, release handle, or manual override. Return it to the operating position only as directed by the manufacturer.
A Worn or Failed Internal Motor Brake
A motor brake may fail even when the external lever looks correct. Internal wear can reduce the brake’s ability to hold the gearbox stationary.
The slide may move when pushed by hand or shift during travel. You may also notice the motor coasting after releasing the switch.
Some motor brakes are not separately replaceable. In those cases, replacing the motor or gearbox assembly may be necessary.
Worn Gearbox Components
Gearboxes handle significant loads while moving an RV slide. Worn teeth, damaged bearings, or excessive internal play can allow backward movement.
Common warning signs include:
- Clicking during operation
- Grinding or popping sounds
- Delayed movement
- Uneven starting
- Sudden jerking
- Visible drive-shaft movement
- Increased movement after releasing the switch
Do not continue cycling a slide with grinding gears. Damaged teeth can strip completely and leave the room stuck.
The Slide Was Not Fully Retracted
Sometimes the room appears closed without reaching its final seated position. This can happen when the switch is released too early.
The slide should normally compress the seals evenly around the opening. However, you should never keep holding the switch longer than the manufacturer recommends.
Low battery voltage can also make the motor stop before full retraction. The room may look closed initially but settle outward later.
Check the battery, charging system, wiring connections, and controller indicators before adjusting the slide.
Schwintek Motors Are Out of Synchronization
In-wall systems depend on both motors reaching the same position. If one side stops early, the room can remain slightly angled.
You may notice one upper or lower corner sitting farther outward. Repeated operation in this condition may increase track and motor stress.
Many systems have a specific resynchronization procedure. Follow the instructions for your exact controller and slide model.
Improvised synchronization attempts can make the problem worse. Stop if the motors sound strained or the room begins twisting.
Loose or Improperly Tensioned Cables
A cable slide must maintain balanced tension across every corner. Stretched, loose, or incorrectly adjusted cables may not hold the room evenly.
Inspect for:
- Sagging cables
- Frayed strands
- Loose mounting brackets
- Worn pulley grooves
- Bent brackets
- Uneven cable tension
- Cable rubbing or binding
Cable adjustment requires small, balanced changes. Overtightening can damage pulleys, brackets, walls, or the slide structure.
A Damaged Rack, Gear, or Drive Shaft
Rack-and-pinion systems need full tooth engagement to hold the room. Missing teeth, loose couplers, or a slipping drive shaft can reduce holding strength.
Inspect both sides whenever possible. One loose coupler can allow one end of the room to move while the other remains closed.
A bent drive shaft may also produce uneven movement. Damaged components should be repaired before repeated operation.
A Faulty Limit Switch or Controller Reference
Some electric systems use limit switches, current sensing, or controller references. These features help determine when the room is fully closed.
A faulty switch or incorrect reference point may stop the motor early. The room can remain slightly open without the owner noticing.
Do not adjust limit settings randomly. Incorrect adjustments may overload the motor or crush the seals.
Other Conditions That Can Look Like Slide Creep
Not every changing gap means the drive system has failed. Several conditions can create the appearance of movement without significant mechanical creep.
- Compressed seals relaxing: Rubber seals may rebound slightly after retraction.
- An unlevel RV: Gravity may pull the room toward the lower side.
- Frame flex: Stabilizing or leveling can change the slide opening slightly.
- Loose interior trim: Moving fascia may make the room appear misaligned.
- Incorrect slide adjustment: Poor seal compression can leave visible gaps.
- Cargo pressure: Furniture or stored items may push against the room.
- Temperature changes: Heat and cold affect seals and building materials.
- A loose exterior flange: The trim may move independently from the room.
Place a small piece of painter’s tape across the slide flange and exterior wall. Draw a reference line across both surfaces while the room is fully closed.
Check the line again after several hours. If the marks separate, you have confirmed actual movement rather than seal relaxation.
How to Diagnose an RV Slide That Creeps Out
Start with simple observations before removing panels or adjusting mechanical components. Careful inspection can often reveal which system is failing.
Identify the Slide-Out System
Look for labels on the motor, controller, pump, manifold, track, or hydraulic cylinder. Your RV documentation may also identify the component manufacturer.
Knowing the system type is important because procedures vary. A method used on one slide may damage another.
Fully Retract and Inspect the Room
Retract the slide while watching both sides from a safe position. Check whether every edge reaches the wall at the same time.
Inspect the seal compression around the top, bottom, and sides. One loose corner often points toward alignment or synchronization trouble.
Mark the Closed Position
Use painter’s tape, a washable marker, or a measured reference point. Record the gap immediately after retraction.
Check again after ten minutes, one hour, and several hours. This helps determine how quickly the movement occurs.
Listen During Retraction
Pay attention to new or unusual sounds. Clicking, grinding, popping, motor coasting, or pump whining may reveal the problem area.
A hydraulic pump that changes pitch may be struggling with low fluid or air. An electric motor that continues spinning may have gear trouble.
Check for External Hydraulic Leaks
Inspect the pump, reservoir, manifold, hoses, fittings, and cylinder rods. Use a flashlight around hidden connections and underbelly openings.
Never use your bare hand to search for a pressurized hydraulic leak. High-pressure fluid can penetrate the skin and cause serious injury.
Check the Manual Override Position
Look for hydraulic release screws, motor brake levers, or manual drive settings. Confirm they are returned to normal operating positions.
This step is especially important after emergency retraction or recent repairs.
Watch for Uneven Movement
Operate the slide while watching both ends. Stop immediately if one side moves significantly faster or the room begins twisting.
Uneven movement commonly points toward motor synchronization, cable tension, gear engagement, or structural alignment.
Check Battery Voltage and Connections
Electric slides require strong battery voltage, even when connected to shore power. Weak batteries can cause incomplete retraction and controller errors.
Inspect battery terminals, frame grounds, fuses, breakers, and wiring connections. Loose or corroded connections can reduce motor power.
Inspect Accessible Mechanical Components
Look for loose bolts, worn gear teeth, damaged tracks, frayed cables, and slipping couplers. Do not place your hands near moving gears or rails.
Support panels securely before working beneath them. Never depend on the hydraulic system alone to hold heavy components.
Review Recent Repairs or Changes
Think about when the problem began. Recent hydraulic work, manual operation, battery replacement, motor service, or leveling changes may provide valuable clues.
A problem beginning immediately after service often involves an incorrect adjustment, open override, trapped air, or loose connection.

Can You Drive With an RV Slide That Creeps Out?
You should not continue driving when an RV slide is moving outward. Even a small gap can grow quickly as road vibration and wind affect the room.
An unsecured slide can damage:
- Exterior seals
- Slide gears
- Hydraulic cylinders
- Motor assemblies
- Wiring harnesses
- Furniture and cabinetry
- Exterior walls
- Nearby vehicles
Pull over safely if you notice movement during travel. Retract the slide and inspect its position before continuing.
A manufacturer-approved travel lock may provide temporary security. However, it should not be used to hide an unresolved mechanical failure.
Avoid using lumber, metal bars, or improvised braces inside the RV. These items can damage cabinets, walls, windows, and slide structures.
Temporary Ways to Secure the Slide
Temporary measures may reduce movement until proper repairs are completed. Use only methods approved for your particular RV and slide system.
- Install manufacturer-approved slide travel bars.
- Confirm hydraulic override valves are fully closed.
- Reengage the electric motor brake or release lever.
- Remove cargo pressing against the interior slide wall.
- Retract the room fully before installing travel locks.
- Check every exterior corner for even closure.
- Reinspect the room after traveling a short distance.
- Avoid towing when movement is rapid or severe.
Never place a travel bar where it can damage a window, cabinet, or thin wall panel. Mark the bar clearly so nobody operates the slide while it remains installed.
How to Fix a Hydraulic Slide That Creeps Out
Hydraulic repairs depend on where the system is losing pressure. Start with fluid level, leaks, and override settings before considering valve or cylinder replacement.
Bleed Air From the System
Some hydraulic systems purge air by completing several full extension and retraction cycles. Others require a more specific procedure.
Do not repeatedly cycle the system while the reservoir is low. Pump cavitation can create additional air and damage internal components.
Stop if the pump becomes unusually loud or the slide begins jerking.
Correct the Hydraulic Fluid Level
Check the fluid with the slides and leveling system in the required positions. The correct position varies between systems.
Add only the specified fluid and avoid overfilling. Clean the reservoir cap area first to prevent contamination.
A falling fluid level usually indicates an external leak. Fluid should not disappear during normal operation.
Close or Reset the Manual Override Valve
Return any manual override screw to its normal operating position. Tighten it only to the manufacturer’s specification.
If the valve still leaks internally, cleaning or replacement may be necessary. Do not force a damaged or seized screw.
Clean or Replace the Solenoid Valve
A contaminated valve may fail to seat properly. However, removing a manifold valve can release fluid and introduce more air.
Correct diagnosis may require isolating the affected circuit. A technician can determine whether the valve, coil, or sealing surface has failed.
Replacing parts without testing may not solve the problem.
Repair or Replace the Hydraulic Cylinder
An internally bypassing cylinder usually needs rebuilding or replacement. New seals must match the cylinder bore and hydraulic fluid.
Cylinder removal can involve heavy components and trapped pressure. This repair is best handled by someone familiar with hydraulic safety.
Repair Leaking Hoses and Fittings
Replace cracked hoses, damaged crimps, and leaking seals. Use fittings rated for the correct hydraulic pressure.
Do not apply plumbing tape or household sealant to every connection. Some fittings seal through flares, O-rings, or machined surfaces.
How to Fix an Electric Slide That Creeps Out
Electric slide repairs focus on the motor brake, gearbox, tracks, cables, and controller. Never force a room that appears twisted or mechanically jammed.
Reengage the Motor Brake
Check whether the manual release or brake lever remains disengaged. Return it to the normal position according to the component instructions.
Test the slide while parked and level. Confirm that the room remains closed after the motor stops.
Replace a Weak Slide Motor
A worn internal brake may require motor replacement. Some manufacturers combine the motor, brake, and gearbox into one assembly.
Match the replacement motor carefully. Similar-looking motors can have different torque ratings, wiring, and mounting arrangements.
Resynchronize the Slide Motors
Follow the exact synchronization procedure for your controller. This often involves completing full cycles without releasing the switch too early.
Stop if one side binds or makes severe noises. Synchronization cannot correct damaged tracks, broken gears, or structural misalignment.
Adjust Cable Tension
Cable systems need balanced tension at every corner. Adjustments should be made gradually and evenly.
Check cable condition before tightening anything. A frayed cable should be replaced, not tightened.
Incorrect tension may twist the room or damage mounting brackets.
Repair Gears, Racks, or Drive Couplers
Replace stripped gears, loose couplers, damaged racks, or bent shafts. Tightening a loose coupler may solve movement only when the parts remain undamaged.
Inspect mounting hardware and brackets at the same time. Loose brackets can create new alignment problems.
Correct the Closed-Position Adjustment
Some slides have adjustable stops, limit switches, or controller references. Incorrect settings may stop the room before proper seal compression.
Make only system-approved adjustments. Setting the stop too far inward can overload the motor and damage the wall or seals.
Repairs You Should Leave to an RV Technician
Some slide repairs require specialized tools, heavy lifting, or system-specific knowledge. Professional service is usually the safer choice for these jobs.
- Hydraulic pressure testing
- Internal cylinder bypass testing
- Solenoid manifold rebuilding
- Cylinder removal and rebuilding
- Motor brake or gearbox replacement
- Schwintek track replacement
- Full cable replacement and retensioning
- Structural slide-room alignment
- Wall-opening repairs
- Frame or floor repairs
- Controller diagnosis
- High-current wiring repairs
Incorrect slide adjustments can cause water leaks, motor overload, gear damage, and structural stress. Professional diagnosis may cost less than replacing incorrectly selected parts.
How Much Does Slide Creep Repair Cost?
Repair cost depends on the system, failed component, labor access, and damage severity. The table below provides a practical comparison without assuming one local labor rate.
| Repair | Difficulty | General Cost Level |
| Resetting an override or brake lever | Easy | Low |
| Correcting hydraulic fluid level | Easy | Low |
| Bleeding trapped air | Easy to moderate | Low to moderate |
| Replacing a hydraulic solenoid | Moderate | Moderate |
| Rebuilding a hydraulic cylinder | Moderate to difficult | Moderate to high |
| Replacing a slide motor | Moderate | Moderate |
| Replacing a gearbox | Moderate | Moderate to high |
| Synchronizing electric motors | Easy to moderate | Low to moderate |
| Adjusting slide cables | Moderate | Moderate |
| Replacing tracks or columns | Difficult | High |
| Repairing structural damage | Difficult | High |
Access can affect labor significantly. A component hidden behind furniture, flooring, or underbelly material may require additional disassembly.
How to Prevent an RV Slide From Creeping
Regular inspection helps you catch small problems before the room begins moving. Focus on complete operation, clean mechanisms, and early warning signs.
- Complete every extension and retraction cycle fully.
- Keep the house battery charged and healthy.
- Maintain clean, tight battery connections.
- Check hydraulic fluid using the correct procedure.
- Inspect hoses, fittings, cylinders, and manifolds.
- Keep manual overrides in their operating positions.
- Confirm motor brake levers remain engaged.
- Clean tracks using manufacturer-approved methods.
- Avoid applying unsuitable grease to exposed slide tracks.
- Inspect cables for fraying and uneven tension.
- Keep heavy objects away from moving slide walls.
- Watch for changing gaps around the exterior flange.
- Investigate new clicking, grinding, or popping sounds.
- Never operate a slide while the RV is severely twisted.
- Use travel locks only when approved.
Also inspect the slide after any emergency manual operation. Override controls are easy to forget once the room begins moving normally again.
When Slide Creep May Indicate Structural Damage
Mechanical problems are more common than structural failures. However, repeated one-sided movement can sometimes indicate a damaged floor, wall, frame, or mounting area.
Watch for these warning signs:
- Cracks near the slide opening
- Separating exterior trim
- Soft flooring around the room
- Bent support arms
- Loose mounting brackets
- Interior wall movement
- Persistent uneven gaps
- A sagging slide floor
- Seals that never align correctly
- Movement continuing after mechanical repairs
Structural problems often make the room difficult to square. The slide may repeatedly move out of alignment even after cable, motor, or hydraulic repairs.
Stop operating the slide when the wall or floor visibly flexes. A complete inspection may be needed before further movement.
Final Thoughts
An RV slide that creeps out after closing is usually losing its ability to hold the room securely. Hydraulic slides commonly suffer from valve or cylinder bypass, while electric systems often develop brake, gear, cable, or synchronization problems.
Start by marking the room’s closed position and identifying your slide system. Then inspect the simple causes, secure the room, and avoid towing until serious movement is corrected.
Related FAQs
Why Does My RV Slide Move Out While Driving?
An RV slide may move outward while driving because a hydraulic valve is bypassing, a motor brake has failed, gears are worn, or a manual release remains disengaged. Stop towing and secure the room before continuing.
Can Low Hydraulic Fluid Cause a Slide to Creep?
Low hydraulic fluid can introduce air and prevent consistent slide operation. However, repeated creep may still indicate an internal valve or cylinder seal leak that requires further testing.
How Much Slide Movement Is Acceptable?
Visible outward movement after the room is fully retracted should be investigated. Seal relaxation may be harmless, but increasing exterior gaps or movement during travel is not considered acceptable.
Can a Bad Slide Motor Let the Room Move?
Yes, an electric slide motor may allow movement when its internal brake fails. Worn gears or excessive gearbox play can also let the motor rotate backward.
Should I Use Slide Locks While Traveling?
Use slide locks only when the RV or slide manufacturer recommends them. They may provide added travel security, but they should never replace repairs to a failing holding system.
Why Does Only One Side of My Slide Creep Out?
One-sided creep commonly results from unsynchronized motors, uneven cable tension, damaged gears, track problems, or slide-room misalignment. Avoid repeated operation when the room begins twisting.
Can an RV Slide Cylinder Leak Internally Without Dripping?
Yes, hydraulic fluid can bypass the piston seal inside the cylinder without appearing outside. The cylinder may look completely dry while failing to hold the slide closed.
Will Cycling the Slide Fix Hydraulic Creep?
Cycling may remove a small amount of trapped air, but it cannot repair a leaking valve or worn cylinder seal. Repeated cycling can also worsen problems when fluid is low.
Can Weak RV Batteries Cause Slide Creep?
Weak batteries may prevent an electric slide from reaching its fully closed position. They do not usually cause true backward movement once the room is properly seated.
Why Does My Slide Creep Out After Manual Retraction?
The hydraulic override valve or electric motor release may remain slightly open or disengaged. Check that every manual control has returned to its normal operating position.
