I copied the following from the Montana Owners Club forum where this problem has plagued early (2010) remote control systems.
==========================================================
The Landing Gear and Stabilizers only working with the remote control and not with the outside manual switches has been a topic of discussion here lately. When ours stopped working "zman08" directed me to a post that solved our problem. It involved removing the ground for the manual switches from the remote receiver and grounding it to the chassis. Apparently there is a "failsafe" circuit to keep the user from using the remote switches and the manual switches at the same time. The connections on the receiver in the front compartment only effect the landing gear and stabilizer switches. The failsafe will not provide a ground to the manual switches when the remote system is energized and will sometimes get "locked" in that position. That is what happened to ours. Like I said, I just moved the ground from the receiver to the chassis and everything works again. You can replace the receiver module, but I think Lippert wants around $150-$200 for it and it will probably just fail again. Our rig is out of warranty so this was the best economical fix for us. I have included a couple of photos of where the wires are for the manual switches and where I moved the ground to.
Members have subsequently reported they had to move the 12V wire from the control unit to a different source in addition to the ground.
