I had a different problem with powergear/valid system. The coach while sitting in auto-mode when, "warm" outside, would sporadically just fully raise in the front. It would not go back to level until I intervened and leveled it. I contacted Valid in Canada. The Service Coordinator (extremely helpful) suggested the keypad as the problem. It seems Monoco has a habit of installing the pad near a window possibly exposing it to moist conditions. Their resonse,
"The water damage may not be readily apparent. Sometimes if you take the metal back panel off (4 phillips screws) and look at the small via holes on the circuit board with a 10x magnifier, you may see signs of corrosion. "
They have new keypads available, a bit pricey however $445 , I found one and purchased through EBay for a ton less cash. Plugged it in and problem solved.
FYI PowerGear was a distributor for Valid Manufacturing, currently not. You can go to Valid website inquiry page and make a request, they will respond promply.
