Dometic DM2882 intermittent shutdown issue

This type problem is either the Eyebrow(the ON/OFF switch) or the rear control board. The NORMAL way to diagnosis is for the Service Shop to connect an exterior 12 volt source to the refer and then test for a week. IF the problem goes away you reconnect the RV 12 volt and test again. IF the problem returns, you have a problem with the RV 12 volt system and NOT the refer. Sometimes it is aa simple as the 12 volt fuse holder for the fuse going to the refer, the spades are "loose" and not tight. Just pinching them back together with needle nose pliers and reinstalling the fuse may fix the problem. This type problem was common on WFCO 12 volt fuse centers. IF the 12 volt supply has been verified that it is NOT the problem, this is when the Service Center contacs Dometic and tells them all the testing and requests that Dometic send a Eyebrow and a rear Control board. If the Service Center has a good relation with Dometic(I do), then Dometic will send the parts and note that the parts were sent even tho there is no positive diagnosis. BUT, you MUST let Dometic know you have done extensive testing and explain what you have done. Otherwise Dometic will not respond. Dometic only talks to Service Centers and qualified techs. NOT retail customers. Doug
