Replacement for 369545 Kwikee Step Motor on 2016 Thor  

Updated 04/26/2026 | Published 04/17/2026

Question:

I’m looking at a motor replacement for my RV step. It’s a 2016 Thor with a one step. It hesitates and sometimes does not come out.. Is there a way to send him pictures.? I took some pictures of the numbers that I could see. Thank you.

Phil, I purchased the same replacement motor for my Berkshire steps. Its a direct replacement. Simple to install. Pay attention on how you take the old one out.

Phil, I had the same part. Fit just fine. Like David noted just pay attention to the order of which you take stuff apart and you'll be fine. No problems. Make sure you note which wires go to what if you remove the steps like I did to be able work on a table with it. No stress doing this work, it was simple and straight forward. Basically the motor is nothing more than a power window motor in the door of your car. Looks identical. The little black box controls it by flipping the polarity across the motor to open and close. There is also a courtesy lamp down there and it's a good time to make that lamp an LED while your there.

On my 2017 Thor 34j it was rather simple to take the old motor out,the numbers for an exact replacement were on the old motor I removed,don’t waste your time with Amazon they sent me several motors each time telling me that’s the one I needed each time having to return it .Etrailer sent me the right one ( same numbers)the very first time and works great

I would first disconnect the arm's motor from the step, then manually cycle the step to ensure there's no issues with a bent pivot point, that's not involved with the motor drive. I'y rve hit and bent step parts that caused the steps to operate roughly and by no fault of the motor had erratic operation. If the steps have no issues than you can reasonably reassured a new step motor should address the problem. Remember, there are stops for the complete parked and extended cycle that you must ensure are adjusted. Good luck

This was any easy swap, matched up perfectly, no issues. Works great still two years later.
