Lippert electric leveling problem

[MGood777]

Sorry for the long post. Hoping the details will help somebody diagnose with me. I have a 2016 Wildcat 5'er with Lippert Ground Control 2.0 electric leveling. I had what I believed was a rear jack motor going bad. It started sounding like it was struggling. I bought a spare motor and kept it in the trailer until I needed it. Finally on a camp trip the jack stopped working and I replaced the motor.

Immediately after replacing the motor, I had all sorts of problems getting the rear and middle jacks to extend and retract. The auto-retract stopped working. I was able to manually work the rear to level the trailer, but the middle jacks were stuck about halfway extended.

I called Lippert who tried to walk me through a "re-homing" of the system. We were unable to complete it. They had me plugging and unplugging the middle and rear jacks at the controller, trying to attach the middle jacks to the rear plugs so they could be manually retracted, and none of that worked. I was getting error messages that didn't make sense to Lippert on the phone. In the end, Lippert couldn't help me any longer. They told me I'd need to use the emergency method to retract the middles and get the system checked out.

What I found while trying to get the middles retracted was that I could run 12 volts directly to the jack motors and they worked perfectly. That's how I got everything retracted. I tested the motor that I thought had been bad and that I had just replaced, and that one worked too.

So all motors are good. Only explanation now (I think...) is that they are not getting 12 volts from the controller. I am thinking that it must be the controller has gone bad. It seems like there's really only 4 parts to the electronics in this system: keypad, controller, motor, wiring. I am getting a solid 12.6 volts to the controller. Assuming there's been no break in wiring and that there's no logic in the keypad, then I'm thinking it must be the controller.

Does anybody think it could be something else? Is there any logic in the keypad? I'm assuming that it's a dumb keypad and just a way to interact with the controller. Controller appears to be super easy to replace. 6 plugs, two battery leads, and mount it properly. Seems like the biggest hassle would just be rehoming or calibration or whatever process you need to do after that.

Am I wrong about any of this? Any help much appreciated.

We have the same system, so I am watching to see if you diagnose the issue.

Ours has, so far, worked well. I am still trying to figure out how to physically obtain access to the tops of the jack posts to grease the gears.

Recalibration, from what I have read, is very easy.

Sounds like you are on the right track. You have confirmed a solid 12.6 volts to the controller. Have you also confirmed the volts to the jack motors? If you find none of the jacks are getting 12 volts, then most likely the controller is not outputting 12 volts. If you have 12 volts at the motors, I would then suspect the touchpad. Perhaps there is a short or broken wire between the touchpad and the controller. When you connected 12 volts directly to the motor, I'm guessing the motor operated immediately and not by using the touchpad since you bypassed the controller for this test?
