Dometic RM555, Alarming in all modes

[cgsnipe]

2011 Edge M21 with Dometic RM555. Digital display flashes and beeps with red exclamation point in all modes of operation, 120v, 12v, Gas, and Aux. Doesnt do it all the time, but mostly. RV battery is good, load tested great, 13.5 volts hooked up with charger working. Propane tanks full. Good 120v source. Online research isn't offering much. Anybody ever have a similar experience.

Found issue. Air gap between top edge of door and door sensor in control panel above it was too great. Adjusted lower hinge to raise door reduced air gap and has been working great since. Thought I'd throw this on her in case anyone else ever experiences issue.
