Steps not retracting when engine is turned on

[humam1953]

Our Lippert RV steps stopped retracting automatically when the engine is turned on. They work otherwise perfectly, that is open and close with the position of the coach door. I replaced the module with the identical one, tightened the ground connections and confirmed there is voltage on the wire coming from the RV electric. What else can it be?

There is a voltage input from the ignition key switch. Absent that signal, the step control has no way to know when the key switch is on. You can test module functionality by applying a voltage to this input, then from there it's a matter of tracing it back.

Thanks, Mark. I referred to this wire coming when I wrote “coming from the RV electric”. It has 12 V when the ignition is on and no voltage with the ignition off. I thus really have no clue what else to check.

If you know what step you have, you can get a copy of the manual from them. The Kwikee step that I had got a signal from the ignition on the yellow wire and it was fused for 6a. Have you looked for a fuse in the signal wire?

The Kwikee product service training manual will help you identify your steps model, and the troubleshooting section will help diagnose the problem.

One thing I found is if I went from OFF to START the steps would not retract
If I went from OFF to RUN/On pause. Then start. they retracted
And yes I know why. the voltage drop when the starter engaged caused a current change that signaled the controller "Retracted".

It seems human has not been back since Thursday so he must have found the problem, or has given up.
