Hydraulic Slide Out issue

[thetechie01]

I have a 2017 Heartland Elkridge 38RSRT. We got it used earlier this year, and absolutely love it!

Recently I have been having a little issue with my slides. All 5 are on one switch, push it and they all go, one after the other. My issue is when retracting the slides. Two of them come in just fine, then the motor just keeps running and the other three don't come in. If I run the others in and out a few times slightly, eventually the others come in with no issues at all, just suddenly works. Happens when plugged in to shore power or not, fluid is all topped off.. I've never had a problem putting them out, only when retracting. Any ideas?

Very well could be the electric breakers going south. I'd replace them. Had to do that both on our old coach and even coach in sig last year. Old coach, 1 switch operated all 3 slides. New one, 1 does the dinette/theater seats and ent center/pantry/stove/fridge. 2nd switch does the main hallway/bed slide. You'll find them near the battery on a buss bar.

You might have a limit switch problem on the last slide that comes in prior to the ones that don’t. I suspect that until the retracted position limit switch is satisfied The rest of the sequence will not work.

That’s interesting.. I’m not sure if they have switches, it seems to just be which ever one has the least resistance goes first, if I put a bunch of weight on one of them, it has changed the sequence. They don’t go out and retract in the same order either. Sometimes one will go half way and then another will start, then it picks back up again after the other one finishes.

Fluid is full

Check your fluid level in the hydraulic resevoir. Must be checked when all slides are fully retracted!
