Recreational vehicle slide-outs increase living space and provide a feeling of openness. But electrical RV slide-out systems can, and do, fail. The time to learn to troubleshoot a slide-out problem is not in a campground with a fully extended slide-out. Take the time to learn how to manually open the electric slide-out on your travel trailer.

Park the trailer in an area clear of obstructions. Make sure the trailer is level before operating the slide-out.

Check the battery and verify it is fully charged and connected to the electrical system. Press and hold the wall-mounted In/Out switch. If the slide does not extend or retract, use the manual override to extend or retract the slide-out.

Find the slide-out motor. The motor is located beneath the slide-out room. Refer to the owner’s manual for the exact location.

Remove the brake assembly from the motor. Use a screwdriver to remove the screws that connect the brake assembly to the motor. Don’t lose the screws. Set the brake assembly aside.

Find the crank extension. The crank extension is located either on the outside or the inside of the frame. Refer to the owner’s manual for the exact location.

Attach the crank handle to the crank extension. The crank handle comes with the trailer. If the crank handle is not available, use a wrench or socket and ratchet to turn the crank extension by hand to extend or retract the slide-out.

Reattach the brake assembly to the slide-out motor. Replace the screws and securely tighten each one with the screwdriver. The brake assembly prevents the slide-out from moving.

Things You Will Need

  • Crank handle


Refer to the operator's manual for specific instructions for the make and model of your travel trailer. Have the travel trailer serviced at a certified service center.


Disconnect the battery from the electrical system before manually extending or retracting the slide-out. Do not overextend or retract the slide-out. This can damage the slide-out mechanism. Wear heavy gloves when manually working the the slide-out to avoid injury.
