I have similarproblem with RM3807 in a 93 excella that had not been used a lot. While I really don't know anything for sure, I believe it to be an issue with control panel circuit board--fridge worked intermitent/slow to start sometimes, then fine--cooled entirely in 5 hours at home, then when at campsite, nothing--no lights on front panel even light, so we used coolers. After several days, when I pushed the button, the lights lit as they should but only for a few minutes. I have checked fuses, 12v
and 110--have appt to take to a service provider next week. Anyone have insight? Thanks.
