Question:

First: My Lippert 6 point leveling system has six individual 15 amp fuses connected to the control board inside the storage compartment. These are not the circuit breakers, but are automotive style 15 amp fuses. They are not labeled, just wired in-line into the circuit control board as mentioned. Can anyone explain what each of these fuses are for? e.i. Each separate support leg or what??? Secondly: My coach only has three side outs and they are all functioning normally but occasionally the support legs will stall the motor when in “auto retract” tripping the circuit breakers which have been replaced with 80 amp circuit breakers. Not certain what this issue is either? Thanks. Sincerely

Expert Reply:

If you're referring to the control module # LC85ED for your Ground Control 3.0 # LC675817 then yes, each fuse is to power each individual leg and should be labeled with which specific leg. If you're moving the slides at the same time while the using the auto-retract feature on the leveling system then you could be trying to pull too much at one time causing the breakers to trip. The system should just have a 50 amp circuit breaker between it and the battery so you may have an issue with how the system was installed on the trailer and would need to trace the wiring with the installation manual (attached below) to determine if it was done correctly.

My Lippert 3.0 is tripping codes of sensor power fail and zero point calibration

@Cody If your Lippert Level-Up 3.0 system is giving you a “Sensor Power Fail” and “Zero Point Calibration” error, don’t worry, these are common and usually fixable with a little troubleshooting. The “Sensor Power Fail” one usually means your system isn’t able to talk to the leveling sensor, either it’s not getting power or the wiring is acting up. First thing I’d do is take a good look at the wiring from the control board to the sensor. Look for anything obvious like loose plugs, cracked wires, or even just corrosion. If something looks off, that could be the culprit. Also check the fuses near your battery, sometimes a blown fuse will trip this code. And it’s always worth giving the system a quick reset: just disconnect the 12V power (pull the fuse or unhook the battery lead), wait a few minutes, and then reconnect it. If that doesn’t do the trick, there’s a chance the sensor might be failing and need to be replaced, but don’t jump there yet. Now, the “Zero Point Calibration” one means your system forgot what “level” actually is. To fix it, you’ll want to manually level your RV with a bubble level (place it on the floor inside where it’s nice and flat). Once you’ve got everything level, turn the leveling system on and press the FRONT and REAR buttons back and forth, five times each, alternating. That should put it into calibration mode. When it says it’s ready, just hit ENTER to lock in the current position as your new “zero point.” Big thing here: make sure you’re really level when you do this, otherwise, the system will remember a tilted spot as level and you’ll be fighting it every time you set up. Also, just make sure your battery has a solid charge (over 12 volts) or things might act funky. If you’ve had any recent work done on the trailer, it’s worth double-checking that no wires got bumped or left unplugged by accident. Let me know how it all works out Cody!
