If you’re having trouble getting the Lippert slide room on your RV to budge, there are a few different things you should do in order to inspect the system and find a solution. More often than not, the problem is a malfunctioning Lippert slide-out motor, which can be caused by poor connection to the onboard battery or an issue with the battery itself.

You may also find that something’s gone wrong with other components of the mechanism, and you can tell whether this is the case if you hit the switch and the Lippert slide-out motor runs but the room doesn’t budge. This is an indication that there’s an obstruction in the hydraulic system.

To help you figure out next steps after you determine the problem lies in the hydraulic system, RV expert Dave Solberg walks you through a quick inspection of the underside of the slide room. He explains that when the Lippert slide-out motor runs but the room doesn’t budge, the the synchronizing cylinder that pushes and pulls the room is likely jammed. He talks about the possible causes of the jam, and tells you how to troubleshoot the system to get it working again. With Dave’s help, your slide room will be moving again in no time!

      I would suggest contacting Winnebago Owner Relations as they would be able to identify what slide mechanisms you have. Typically the bedroom slide would be a different mechanism than the livingroom so there may be two separate issues? The first thing I would check is 12-volt power to the motors? Next, if it’s a hydraulic system, check the hydraulic fluid in the reservoir. After that, there needs to be more information on what is happening when you try to run each of the slides. Do you hear the motor try to run? Check these things first and let us know what you find.

    We are also having slid out issues – only one slide out – living room – it will not move. The motor doesn’t engage. WE have checked the wiring, and replaced fuses. its a 97 Jayco, and we are not close to where we can take it to a dealer. Any assistance would be appreciated, esp as to where we can get replacement parts, etc.

    Need help with slide outside. Was intermittent with clicking from solenoid. Put in new battery, 1 slide came in, other half way then nothing. Solenoid no longer makes clicking sound. Check fluids and breakers, all good. 2008 Keystone 311bhs.

      Dear Charlie,

      Thank you for your patience. In response to your question-

      It sounds like either the pump or solenoid is going bad. It could also be low voltage, even with a new battery there could be low voltage from a loose or bad connection. The best thing to do would be to check the voltage at the solenoid and pump while the button is pressed. If there is a lack of voltage to the solenoid, the problem will be before it. Could be a bad connection at the switch or control board if you have one. If the voltage is good to the solenoid but bad at the pump, the solenoid is bad. If the voltage is good to the pump and it doesn’t run, the pump might be bad. Since the fluid level is good and the breakers and fuses are fine, check the actual voltage is the next best thing to do and see what components are doing.
