Kwikee Step won't Retract

Sounds like the gears are stripped. Need to take it apart to check. Still under warranty ?

While you're at it, use compressed air or whatever it takes and clean all the joints well, then lubricate.
Maybe dirt and the lack of lubrication helped cause your problem?
It's good PM.

I know this always sounds so terrible to suggest...but take a hammer and tap the motor housing for the step a few times! Sounds Crazy but I did this for year's until finally replacing the motor and still, infrequently, I have to tap away to get the steps to retract.

Seems like it is binding but the grinding sound might be the gears as you say.

I'll give it a look and see.

Your main drive gear has broken teeth. You may be able to drop the motor and rotate that round gear in the gear housing past the broken tooth and it will still work. Doug

time to replace the gear box
i replaced both the motor and the gearbox on ours March 2015

My Kwikee step was doing the same thing (loud, ratchety noise and steps would only partially close). I knew either the motor's plastic gear was stripped (highly likely), or the main linkage assembly metal gear was toast (less likely).

I found the Kwikee Service Manual PDF online and found the replacement motor for my particular step on Amazon for around $66 bucks. In less than 30 minutes, I was able to replace the motor myself and problem is now solved!

Here's the video of my repair: https://youtu.be/jJ4Rt5wJahU

I plan to buy another motor and keep it on hand. These motors tend to fail every couple of years (or more often if all the step joints and linkage pin are not lubricated frequently, or RV is not frequently used).

LB311: Might be exception ot the (your) rule....but my Kwikee steps are just fine after 15 years.

Now that I've said that..........

I spray with silicone maybe 3 times a year.

Probably stripped gears, but there may be a chance the motor came out of place and is not making good contact with the gears. It's worth looking at. If it is gears, hopefully you can have them replaced or machined.

Mine is a 1999 Allegro Bay with the Kwikee Steps (I think series 32)...it's a double step. I was having similar problems but I could help mine in. Finally two days ago it quit altogether. A little hum, a click and nothing. I read on another site that the left front window lift motor from a '86-'95 Ford Taurus would work. I went to my local AutoZone and they had one on the shelf for $42.99. I took my old motor/gear off the steps, swapped out the large gear from the old one to the new one, bolted it back in, cut and reconnected the wiring (same color wiring on both the old and new) and it came back to life. It fully retracts (which it hadn't done since I bought it) and fully extends. I don't remember the Autozone part number but it came with a Dorman label and part number 742-277. Hope that helps someone!
