Slide room creeps out on its own ???

[Trailer Trash]

We have an 09 Bighorn 3370, the bedroom slide will creep out a few inches on its own while at home in the backyard connected to power 24/7. FYI when I open the slides it is the first one to open. Any ideas what causes this? The other 2 slides do not do this. Thanks

I had a similar issue years ago. My problem was an internal leak at the hydraulic ram for that slide.
Although it's a bit of labor it can be a DIY project.
You can find information in the Tools section, here.
Check the Slide-out Service Manual.

Peace

It’s likely a small hydraulic leak or low pressure. Check the fluid levels and inspect for leaks around the bedroom slide’s seals or lines.

Its not loosing any hydraulic fluid in the plastic tank tank ?

Mine was a leak in a crack in the weld at the fixed end of the cylinder.

internal leak in the valve you will not see. It's fluid leaking past the valve seat or seals in the cylinder. Cookie in post #2 stated hid problem well & how to check into the issue.

Replacing the hydraulic cylinder is doable if you decide that is what is needed. It is a messy job but this Lippert video helped me.
