Looking For Replacement Control Unit For Kwikee Steps 9099507000

Hey Gregory, I think you meant Kwikee controller 909507000, which is just one digit different from the number you provided. The Replacement Control Unit # LC59VR is a direct replacement for it if your steps are having issues extending, retracting, or operating consistently, assuming your battery, wiring, and switches are all working properly.

You might also consider spending a little more on the Kwikee Motor Upgrade Kit # LC379145. Rather than replacing just the controller, this kit upgrades the motor, gearbox, linkage, and controller, giving you updated components throughout the operating system.

We'd just need to confirm your Kwikee step series to make sure the upgrade kit is compatible. It fits 22, 23, 28A, 30, 32, 33, 34, 35, 36, 38, and 40 series, but there is another kit for the other handful of series.

You are correct on the part number—fat fingers! ;-) The LC59VR does not have the same wiring configuration as my current step controller. Specifically, the new controller has a single-pin connector where the old controller has a two-pin connector going to the step motor. Is there a wiring diagram showing how to adapt the existing wiring to the new controller, or is there a conversion kit available to make the two compatible? Thoughts? Thanks again for your help! Greg

@GregoryT Hey Greg, thanks for catching that lol. The # LC59VR is listed as the replacement for your original 909507000 controller, and it includes wiring connectors and installation instructions. So it's interesting that you're seeing different connections on yours. Could you send me a picture of your existing controller and its wiring connections? You can reply to this email you get the response from, which is [email protected]

@GregoryT Thanks for the pics via email, Greg! Do you know what model steps you have? There should be a part number somewhere on the assembly. I just spoke with Lippert, and despite the matching part numbers, they said the controller I recommended may not work with your older wiring without modifications. They're recommending a complete upgrade kit instead, which costs a little more but ensures everything works together.

@GregoryT Hey Greg! Thanks for sending those additional photos! I can now confirm you have Kwikee Series 42 steps. After looking into it further, we don't have a confirmed plug-and-play replacement controller for your older setup. Although # LC59VR is listed as a replacement, the wiring differences you noticed could require modifications and Lippert /Kwikee wasn't able to confirm compatibility. The better option that would for sure work is the Kwikee Motor Upgrade Kit # LC380266, which is specifically designed for older Series 42 steps. It includes a matching motor, gearbox, controller, and wiring harness, so you won't have to try adapting the original motor to a newer controller. Sorry for the earlier confusion! We needed those photos to identify the correct upgrade for your steps. You may have luck searching for the older controller on ebay or other used RV part sites though.
