Troubleshooting a Lippert Slide-Out: Motor Runs But Room Slides Slowly

Duration: 0:54

Slide rooms are high on our list of must-have upgrades for a more comfortable RV experience. Whether you’re taking a weekend escape or a cross-country tour, it’s nice to add a little extra space to your living quarters with the push of a button. However, despite their convenience and ease of use, slide rooms are susceptible to the occasional malfunction, which can be a pain if you’re miles from a repair shop and are unsure how to troubleshoot the problem. In this lesson, we teach you how to solve one of the most common issues: when the Lippert slide-out motor runs like regular but the room extends and retracts slowly.

Testing your Lippert slide-out motor

You find the ideal spot to set up camp after a long drive, and you go to extend your slide room so you can move comfortably throughout your RV. You activate the Lippert slide-out motor, and although it seems to be fully functional, the room inches out slower than normal. All you want to do is kick back and relax, but the room is taking its time. There could be a number of reasons for this.

To help you diagnose what’s ailing your slide room, RV expert Dave Solberg walks you through a quick troubleshoot demonstration. He shows what to look for when you pop open the hatch to asses your Lippert slide-out motor, so you can eliminate all other options and find your specific cause.

First things first, Dave reminds you that a Lippert slide-out motor is attached to your RV’s house batteries, so if they’re not completely charged, the motor isn’t going to run at full capacity. In addition, the batteries must be operating at the maximum 12 volts. Next, he teaches you how to check for loose connections in the grounding, which can also lead to an inefficient Lippert slide-out motor.

Finally, Dave talks about the effect extreme climates might have on your Lippert slide-out motor, and particularly the oil its hydraulic system relies upon to push and pull the room. If you utilize Dave’s tips for troubleshooting your slow slide room, it should only take you a few minutes to find the issue and figure out a solution!

      Hi Karl,

      Thank you for being patient while I reached out to the expert, here is the reply:

      The main slide on your unit will have a motor underneath of the slide at the end of the actuator arm. The manual override will be done at the motor. There is usually a nut or bracket at the end of the motor to be able to operate it with a wrench or socket. Jayco usually uses 5/8″ sockets to operate their slide outs. There should be an access panel to the motor underneath or in a compartment. If you look under the slide and find the actuator arm and follow it back to the other side of the coach this is where the motor is located. Sometimes they do put a manually override extension on the other side of the slide but you would have to check the owners manual to see if your model has that option. As for your issue most likely the switch is bad. These motors are bi-directional and work off of the polarity being sent. If the motor works fine in one direction technically it should in both so most likely there is a voltage issue from the switch.

    If your hooked up to power 15, 30, 60 amp, does your slides still run on battery power? Do your fifth wheel batteries charge during towing?

    most of the videos have commercials that last longer than the video- and you cant bypass the commercials like utube can. just gotta deal with it for a minute. what a waste of 49.oo. I spent my money to learn about RVs not watch commercials of things I will never buy.

    That’s nice but it is not enough information to fix anything but perhaps a loose connection. There is not enough information in any of these videos to make me want to spend the money for a premium subscription. You’re selling sizzle, but there is no steak!!
