With the Error RF on your system, since the unit will not go up or down, I recommend checking the connection wires on that jack. If there is a lack of power to the jack, this error will occur. Test the wires using a circuit tester like # PTW2993. Next, test the jack using a 12V jumper wire and ground while disconnected from the system. This will help you know if the jack is bad, or if there is a connection that is bad. If the front leg is bad, you can use the Replacement Lead Leg for Lippert Components Ground Control 3.0 Electric Leveling System - Qty 1 # LC305340 or just the replacement motor # LC343758.

If the leg is working, then you will need to trace the wires back checking for power along those wires when attempting to operate that leg. Trace it all the way back to the control module. If it is not working there, check the corresponding fuse and if needed, replace the module with # LC304136. The power to these jacks is very sensitive, so you need to make sure 12V is getting to each motor.
