Slide out retracts on it's own

Good day folks,
The slide out on my Infinity has just begun to retract a bit on it's own after extending? Usually just an inch or two and then seems to stop. I'm guessing it relates back to a solenoid but I figured I would see if anyone else has experienced something similar and repaired. I have replaced the four solenoids on my jack system without any problems so I'm hoping its something I can take care of on my own. Thanks in advance, Mike.

Hard to say when you don't list what RV you have, or what type of slide system. From your user pic, I am surprised that you have a slide at all

List your RV in your signature. Much easier to get help then.

Just taking a wild guess if you have a powergear motor driven slide it might be the brake leaver has disengaged on the motor.

Air in system compresses, after the hyd motor stops the air pressure takes over. Liquids cannot be compressed.
If your hyd system is HWH brand, the only way to remove air is to operate the slide out- then in, then refill oil reservoir to proper level. Continue doing this until oil level remains constant. HWH did not install air bleed valves.

Thank you Ray, I didn't even think about air in the system. I will do as you mentioned and see if that takes care of the issue.

CAUTION: Do not use hydraulic jack oil!! That is stated on the HWH FAQ page too.

When HWH owners have had complaints of slides or generator trays moving on their own, it has always been a solenoid valve that is internally bypassing (leaking).
If there is air in the system then it would buck and complain when moving back / forth. Then, one would have to ask how did the air get in there to the extent that the slide was moving.

I think you need a valve.

You may be right, new valve needed. Air gets into a closed system when the oil reservoir level drops too low when everything is extended.

Right, but that implies that the reservoir is either too small (very unlikely) or that there is an external leak where the fluid went. That should have been noticed by the OP...

That is the main reason for the admonishment to check oil level per maintenance schedule and maintain oil at full mark in the HWH owners manual.
That is one of my monthly MH checks.

Yep, mine started going out on it's own when traveling or stored. Replaced one of the solenoids and that fixed it.
