Troubleshooting Random Codes Popping Up on Lippert Ground Control 3.0


I have a 2016 Montana High Country 5th wheel camper with a 6-point Ground Control 3.0 system installed on it from the factory. I am getting a couple of codes on it when trying to Auto-Level the unit. Sometimes the system will blow the circuit breaker when only running the front jacks when the Auto-Level process has started. Then most recently I had a error on the front left jack. This caused me having to reconnect the camper and re-capture all the jacks by extending all the jacks about 6 inches, then holding the retract button to retract all the jacks. I had to do this three times repeatedly because the front left jack would Error every time. It sounds like those front jacks are working harder than they probably should. Once the front and rear jacks got satisfied, the middle jacks started their normal sequence leveling process and the right hand middle jack said it was out of stroke. This camper is parked in the same level spot in my pole barn as it has always been like every other time when we return from camping. The unit was plugged into shore line power so the battery voltage is normal. Can you please help me with trying to troubleshoot these problems?

It sounds like you have a bad connection or connections on your Lippert Ground Control 3.0 # LC675817 system. It sounds like you've seen some of the codes and gone through some of the troubleshooting process aside from the connections and wiring so that's where you'll want to start. You can verify that the issue is electrical if you pop the plug off the top of each jack and you're able to manually extend and retract each jack just fine.

Lippert has a few troubleshooting steps to take when the issue is electrical:

1 - Check harness connections at controller and at jack.
2 - Check harness for damage.
3 - Check fuses at controller.
4 - Repair or replace as necessary.

If you are unsure and/or uncomfortable looking at the electrical side of things I recommend having an experienced friend or shop taking a look at your setup to see what needs to be replaced.
