Ok need some help here we have a 2009 3400rl with four slides, the slides all work fine but the bedroom slide comes out about 4 inches after it is closed,does not come out right away it take it a couple of hours to work its way out. I have check the fluid level that is fine any one else had this problem.

You may have a leaky cylinder, this may help you isolate it.

You may also have a valve not completely closing.

I had all slides creeping out after a couple of hours. Lippert replaced the 2 big slide pistons. They said it is usually the two big ones that go bad. It worked. I even had shut off all the valves when traveling thinking that would lock everything in place. Instead, the kitchen slide came out about 4-5 inches!! (When they all came out, it was less than an inch)
So it may not be the BR slide that is the problem.

We also had trouble with the bedroom slide opening. As it got worse 2 of my slides would open 3 inches as we were travelling. It turned out to be the cylinder on the kitchen slide. The fluid was leaking past the seal. Keystone finally did a system pressure check and found the bad cylinder.

Our bedroom slide inches out as well...started this year...but not all the time...only once in a while...can't see any leaks, fluid is full...we do "bump" the switch back to help relieve the pressure...seems to work well...but if we forget to...sometimes it stays in and sometimes it creeps out a couple of inches....go figure...

We had that problem last March when we left Florida. We put them in in Orlando and when we got to Jacksonville it had warmed up and the slides started to creep out. We finally figured that when the wife put them in she would stop when they were all the way in. Now we hold the button for a few seconds after they are in and it has not happened anymore. I think the fluid was expanding as the temperature warmed and pushed them out.
