I'm putting this out to whoever is experiencing problems with your older Kwikee step units. I have a '95 HR Cummins/Allison 33' pusher. Started experiencing step activation problems 3 months ago. After some testing discovered that the motor/drive assembly and the step itself were working fine ( no binding, grinding, etc.). The problem appeared to be the step controller...a small triangular plastic box next to the step itself underneath with a wire harness coming out.
After spending $185 with some gyrations from the "techs" at Lippert Components (Kwikee step company) , bought a new controller. It only worked for a week. The door magnetic switch they sent with it was the wrong one. Why didn't I know about that??! Bottom line is this...they now tell me that there was a 50/50 chance of this not working with my new part...news to me after the fact!
This fix is easy and reliable...took me a while to figure it out...simply install a DPDT momentary rocker switch prewired for reverse polarity at opposite switch positions (works just like a car window switch). Order one from Del City electric components, it's part number 7700060 and costs about $25. The switch is already setup to reverse the polarity in each of the two rocker positions and it rests in the middle which is "off", bottom line... open the dang steps when you want them down. Close them when you want. Stop messing around with control units and suspect wiring in your unit which may or may not be good...Us older folks need to simplify our lives...Just sayin'
