Kwikee Electric Step

My 3-step Kwikee will not retract even when I start the engine. I've checked underneath and do not see any obstructions nor any obvious broken wires. The motor hums as if it is extending or retracting but nothing else happens. Oh, the under step light comes on and then goes out. I've looked at my #888 manual to see if there is a manual way to retract but not luck. Anyone have any ideas? I am somewhat capable of checking currents with a volt meter. Thanks.

Kwikee has a good trouble shooting web site with a wiring diagram which shows what each wire does and what should have voltage when.

Thanks Tha_Rooster! I went through the electrical checks and found all voltage readings to be at spec. I am suspecting that the gear within the motor housing is shot. The motor sounds as if it is going through normal operation but the big table gear (I believe that is the proper name) doesn't move. I attempted to remove the motor housing by extracting the 3 hex screws, however, the screws simply turn without backing out. It is almost as if there is a nut on the backend of each screw and the screw/nut assembly is turning. Everything I've read indicate these screws are self-tapping and should back out. May be I need to apply some downward pressure as I start backing out these screws but I'm not sure. BTW, the stairs move freely after I disconnected the linkage to the 'table gear'. I had to put wheels chocks behind the lower step to keep them extended. Any help will be greatly appreciated.

Where you parked a long time before this happened? The reason I ask is, these steps will sieze/rust up easily when left extended and subjected to rain. The motor operates (shuts off) on resistence. I had this happen to me twice after long stays, even though I'm good about keeping them lubed.

I had to disconnect the motor arm, soak all slides and pivot points with penetrating oil and move it in and out by hand until it moved freely. It doesn't take much resistence to keep them from moving.

I don't think it is the big 'table gear' since it freely rotates completely around. I would expect resistance with the motor gear but nothing. That's why I suspect the gear inside the motor. Just having a dickens of a time removing it.

We had just returned from a 5-day outing but no rain. It retracted nicely when we left and only stopped working when we got home. Stopped once on the way to readjust outside mirrors - Maryland overpass bridges on Rte 70 wreck havoc on the MH!

It's probably the motor gear then. Good Luck.

Finally got the motor assembly off! Three hex screws with nuts, not self tapping as my manuals indicate. Used my power driver to get all 3 off but took 5 minutes on each. Gear inside was in 4 pieces. Now, finding the correct replacement is next. Thanks to all with thoughts and ideas. I'll give a thumbs up when I get it done!

For everyone's info you can buy the "slug" gears and the large gear from Amazon or Advance Auto handy for spares.

Reordered a different AMS motor...same motor but with the pinion gear. After multiple installations just to get pinion gear and table gear aligned in the right positions (Specific to Series 24/25 Kwikee Step, since discontinued), success was achieved! If it fails again, I will change to a new model step. Thanks to all for your words of wisdom and general support.
