Slides move a little then stop

[Tdalton]

I have a 2016 legacy 340KP the slides move a little then stop. If I wait a few minutes and try again they move a little and stop. The batteries are new and are fully charged and the motorhome is leveled.
This is a issues that seems to come and go. Sometimes they work great then some times they creep in and out?
The picture is of the slide control center.

if these are schwintec slides with the rails and motors, I have the same issue at times, but going back and forth a few times tends to work out the kinks and the slide then moves all the way. Could it be the batteries? yes, although it might 'seem' like the batteries are fully charged, it could be that this 'big draw', without any additional juice/help can easily cause the controller to 'see' low voltage and stop. Could it be the controller? yes, as the controller measures the difference between the two end motors and will stop the movement if one end binds, or one motor has a much larger draw than the other, etc.
When the slide motors are not exactly in 'sync' with each other, this issue tends to be more pronounced. The easiest way to overcome this from being a normal issue is to continue holding the slide button for several seconds AFTER the slide is either all the way extracted, or all the way retracted, listening for the tell-tell 'zzzziiiinnnnnngggggg' of one of the motors coming in 'sync' with the other, after the slide stops.

Thank you for your reply. Yes it is the schwintec slides. We are new to RVing so I'm not completely clear on the steps for the slide. It is connected to a hookup but I'm not sure if it's only drawing power from the batteries or from the hookup.

I don't know if the same thing applies, but my big slide would come in about halfway, then stop. I wait a few seconds, and hear a "click" from the battery area. Bring the slide in a little more, it would stop, wait a couple of seconds, "click", and so on. I traced it down to a relay that had gone south. I replaced the relay, and it works like brand new now. Something for you to maybe try and trace anyway.

I had that issue once upon a time and it turned out to be a motor sensor giving the board a fault.
Your Schwintek board will flash a fault.
The next time your slide moves and stops go out to the board and see what it's telling you.
Fault codes are printed on the board.
Good luck!

We had that exact problem on our Forester MBS 2401 FS which uses a Schwintek slide. Schwintek's first guess was a bad motor, but that did not fix the problem. Their second guess was the controller board and switching that out fixed the problem.

New here....greetings

I have a 2007 Sandpiper by Forest River with 3 glide outs. The glide outs intermittently stops and starts after resting 15 seconds or so. I replaced the glide out switch and no help. I see a 30 amp fuse inline from the battery compartment and it looks good. Any other suggestions. Please forgive me, but I'm not too savy on electrical...female and all.
Thank you!!
