One Side of Slide Out Not Working: Causes & Solutions

one side of slide out not working

A jammed mechanism, improper RV position, lack of lubrication, hydraulic issues, failure of slide-out switch, and battery problems are some of the most common causes of one side of slide out not working.

You might also hear a clicking sound, which indicates problematic components affecting the functionality of the slide-out.

The good thing is that these problems have quick solutions. It can be as easy as checking for stuck debris or making sure that the power supply is working. Keep on reading to learn more.

RV Slide Out Problems and Troubleshooting

Mechanical problems are common in an RV slide-out operation. It can be frustrating, but there are quick fixes worth trying. Here’s a quick look at the potential causes

1. Jammed Mechanism


If the RV slide goes out but not in or is stuck on one side, it’s possible that an object is stuck in the slide, preventing it from moving normally.

Inspect the slide and watch out for debris or anything causing the clog. Removing whatever causes the jam should fix the problem.

2. Improper RV Position


Another thing to check is whether the RV is at a level position. Gravity might be preventing the slide-out from moving.

You’ll need at least two people to fix this issue. Have another person help bring the slide in if you extended it before leveling the RV.

Control the switch to quicken this process, and make sure to park the camper correctly before operating the slideout again.

3. Lack of Lubrication


Proper RV maintenance requires adequate lubrication, making sure that the moving parts (gears, cables, rollers) are working.

Hence, if the slide-out won’t come in or out, an easy fix would be lubricating the slide mechanism. Apply the lubricant on the slide tracks after cleaning them.

4. Hydraulic Issue


When the motor runs but the slide does not move, you might want to look at the hydraulic system. Over time, it can leak and malfunction, or the actuators need replacing.

The hydraulic fluid reservoir must also hold enough liquid for the slide to work. Otherwise, it needs a refill.

Aside from checking the reservoir, you may also loosen the relief valve for better liquid flow.

5. Failure of the Slide-Out Switch


Switch problems are among the most common culprits when the slide-out malfunctions.

In most cases, you must be able to hear the pump or motor running, which is indicative that the slide-out is working as it should. If there’s no sound, then the switch could be at fault.

Repair or replacement is the best solution to this problem. In RVs with multiple slide-outs, you can test the switch individually to be sure that it is indeed causing the problem.

6. Battery Issue


The battery powers an RV’s electrical components, including the slide-out. As shared by one user, the solution can be as easy as making sure that the battery is charged. Your converter must also be receiving sufficient power.

The next thing to look at is the terminal, as it can be corroded or damaged. A quick visual inspection can confirm this. If it is, then you’ll need to replace the connectors. The battery itself might also need a replacement.

7. Clicking Soundclicking-sound-with-slide-out

You might hear a clicking noise when the slide-out moves in and out. It can be alarming, especially when it’s loud. As shared by one user on an RV forum, the issue could be broken parts.

Specifically, the problem could be the clutch mechanism or the roll pin. Check and replace them if necessary.

Further, the noise can also be caused by other problems. For instance, it could be from a stuck debris or bent shaft.

Meanwhile, other parts can also be damaged, including the track and the bearing. Make sure they are all in tip-top shape.


Overall, one side of slide out not working can be annoying, but you can fix the issue yourself. For instance, you can check for debris causing the jam or check the battery, making sure there’s a power supply. Sometimes, it might just need a lubricant, so maintenance is important to avoid severe damages.
