Wire Diagram for Lippert Power Steps for Troubleshooting Wiring and Power Module

Updated 07/13/2026 | Published 02/17/2017

Question:

My steps will not retract. I tested the voltage into the control mortal and it was 12.s volts. I tested the voltage out, on the pigtail that connects to the motor, and found no voltage. I had my door closed and the step switch turned to on. Likewise, the steps do not retract when the ignition is turned on and the rig started. If my testing was faulty, and it turns out not to be a mortal problem, what is the return policy? Long time etrailer customer.ski

If you check out the diagram I attached you will see how the steps should get wired up. What I would first do is verify that you have voltage in all of the right places on your steps to determine if the module needs to be replaced with the # LC301702.

The green wire gets grounded to the chassis.
The white wire gets connected to the power switch which then goes to the positive battery post.
The yellow wire gets run to the a keyed power source, power only with ignition on.
The red wire connects to the positive battery post for the motor.
The brown wire gets connected to door switch.

I attached a link to our returns policy page.

I have a 2010 damon challenger with an electric step. The step retracts and extends when the ignition is on but not when the step switch is on and the ignition off. I do have power to the white wire at the 4 pin plug when step switch is on.

For some reason the switch is only getting power when the ignition is on. This very well could point to a bad control module since this is where it ties into on the setup. As long as you have a good connection with the white wire you mentioned and the yellow wire (with no visible sings of damage - exposed/frayed wiring) I think replacing the module is your next step.

I own a 2012 Georgetown with electric steps. How do I keep the steps retracted when I store it? Thanks

Where does the purple wire attach to? On my Tiffin, it just hangs there with one end bare.

If so equipped, the purple wire got the step light switch. If your model does not have a step light then this wire would not be used. If not used, I would snip off the bare end and tape it off.

Dear Expert, I am trying to install the Lippert U-series treeple steps but unfortunatelly I can receive the proper effect:( It seems that steps not retract when yiu are trying to close it. I can send you a short movie for this situation, and maybe you will be able to help me. Thank you in advance!

@Jan Are your steps not retracting when the door is closed? Do they do anything when you open the door? Sounds like an issue with the door sensors which I would make sure are wired up properly first.

I just updated my step controller to the Lc30172 I had to cut the plug because it was different and then connect all the wires my question is what shuts off the power to the step motor? There is always power to my step wires causing the motor to get hot?? I reversed the step wires and it will go in the other direction but the wires are always hot? The only wire I have connected is the power wire?
