More likely a dead spot on the motor. I have this with my Kwikee Steps. Short of replacement it might be possible to "re-index" the motor. but I don't know if that will help. To Re-Index.
IF and I really stress that **IF** your slide is like mine run out about half to 3/4 the way (Actually most any thing between full out and full in) under the slide you will see the racks and gears.. I can pull a pin (Carefule of waskers( It is a "hair pin" type pin like those used on some hitch pins.
Knock the gear sideways, Turn it a notch, or two, and then knock it back and re-pin it.
Do both gears same number of teeth
Might work but.. I will not guarantee.. Problem may return.. New motor should fix and that is **IF** (that big if again) the problem is teh dead spot.
Those controllers are strange
I sometime find I have to hit IN then OUT to get mine to work.
Home was where I park it. but alas the.
