I purchased and installed the LC363985 controller in June 2026. It is working perfectly, was easy to install, and seems to be an exact replacement for Kwikee part # 1510000140 REV 0A, which is what was on my 2011 Tioga class C. Potential buyers should note that Kwikee/Lippert has made about 10 different step controllers over the years that all look the same, with the same wire connections but different circuitry inside. That is to say, they are outwardly identical but functionally incompatible. I had previously purchased a controller (claimed to work with 40 series steps) from a different internet retailer which looked like a bargain but caused my steps to function erratically. The folks at etrailer were very helpful in making sure I got the correct replacement part for my application. I found the part description for the LC363985 to be confusing because it says it fits 40 series steps built before 1999. The ID label on my steps has long since peeled off, so I’m not sure what series they are, but I’m pretty sure they were built after 1999, since the vehicle is a 2011 model. It would be helpful to provide a cross-reference between the old Kwikee part numbers and the new Lippert part numbers.
by:
Easy to install and works perfectly. If you need a replacement I recommend purchasing this product.
by:
Have bought from etrailer several times and always a great experience
by:
This was quite simple to install. All the wires are made to plug right in to the existing wires. The “bolt pattern” to reattach the control unit is the same as well. I was a bit surprised that the 3, 1/4” self-tapping were not included - so save the old ones that came off the original controller.
by:
This was an exact replacement for my 2018 Newmar. The description, on the etrailer website, was a bit confusing regarding which steps it fit. I called and William got things straighted out and on order.
Excellent customer service.
by:

Flawless. I just expect it to work all the time now, and dont really even think about it.

by:
As advertised, works- so far so good!
by:
Installed with no issues.
by:
Just installed it and seems to be working fine, time will tell
by:
Good price, quick to ship, easy fit and seems to be working flawlessly. The old controller was intermittent and the issue may have just been the ground connection to chassis but if the problem is gone fit good, I don’t care.
The only delay in receiving it was caused by the Post Office and that was just a couple of days. I’d pay a little for freight to avoid USPS.

I want to say that this company employs very professional and knowledgeable people. The product that we ordered arrived quickly, packed great and was so easy to install it was almost to easy. Just change each wire with the matching one on the old item. Actually the new one screwed right in to the old holes from the old product. He finished installing it and low and behold our motor home step was working perfectly! Thanks Noah for have the knowledge of exactly what I needed. Now we know where to turn for things we need. Great company etrailer!

Great - Our RV steps are working fine and we havent had any issues at all! Thanks again!

by:
Steps were possessed and while traveling down the road. Would extend and retract on their own. Unplugged the power to them to get home. The part ordered was identical to what was on the RV including the factory part#. I had replaced the magnetic switch before getting this but the steps extended when the ignition switch was turned on. The original controller had the purple wire going to the mag switch and the black wire went to the step light. Hooked it back up that way and steps retracted when ignition switch was turned on. This was on a 2019 Jayco Greyhawk.

Service was great from etrailer. Thanks guys.
by:
Thank you for helping me identify which controller to purchase. I installed it and everything is working like it should.

Outstanding customer service.
by:
Less than one week before due to leave on 2 month camping trip. Controller for Kwikee power steps on motorhome failed. Contacted Tammie at etrailer for help. As always, they came through with flying colors. Had the controller available and shipped to me with delivery 2 days after.
Controller was exactly what I needed and very easy to install.
etrailer and Tammie in particular, saved the day for us
Superb company with service that is above and beyond and shows what excellent customer service is.
by:
Christina in customer service was outstanding. She helped me get the correct replacement parts. We had to hard wire the motor since two wires to the control unit and the motor were not the same type connector (male/female) to connect. But we are extremely satisfied.
by:
I was really unsure if I was ordering the right part, but after talking on line with one of your reps, he assured me it would work. Shipping was free and I received it in a few days, got it installed on the RV, and it works great! The cost was about half what I would have paid, at other places. So I am thrilled with the cost and the customer service! I will be back in the near future!
by:
This controller replaced a shorted unit (would blow 25A fuse) on a 2000 class A RV. I had to splice the motor connector off the old unit as it was different (the wires were the same color). The logic on this unit is reversed regarding the on/off switch by the door, but works just fine.
by:
The part was a direct replacement. All wiring connections except 1 were plug and play. My rv had 1 connection hardwired, simply cut the plug off and made the connection. I replaced both the motor and controller at the same time. All of the troubleshooting pointed to both. It took me longer to gather all of the tools than to make the repairs.
by:
Exact replacment for the attached picture.
