In order to test the motor on what I assume are set of Lippert Kwikee Electric Steps, you will first want to sever the yellow and red wires on the motor. Once you do this you will then need to obtain access to a 12 volt power source you know functions. If you take the red wire and place it on the direct 12 volt power source while grounding the yellow wire, the step should then either extend or retract. If you switch the wire leads, yellow to power and red to ground then the step will go the opposite way.

In order to test the control module you will first need to obtain the Lippert Components Kwikee Step Tester part # LC379416. Once you have this then you can use the attached photos to test the control module. If you do need a replacement motor or step control module then please give me the series and part number of the steps you have now and I can provide them if available.

If your Kwikee steps intermittently retract or extend and you're also hearing a clicking noise there could either be a missing a tooth (or teeth) on the gears, or it could also be the motor. It also could just be a wiring connection issue. I do…

It could be an issue with the motor. If you can hear it running but nothing is moving, the best thing to do is to start by bench testing the motor. You can hook up to 12v and ground and the motor should run and turn. If you can hear it run but…

Answer 11

Bruce, this is fairly common, and the issue is usually with motorhomes that are wired to work with a normally open circuit and the steps being meant for a closed circuit. To fix the issue, you'll just need to use the Replacement Door Switch for…
