Dometic DM2852 Not working on AC

The wires from the lower rear board to the eyebrow are buried inside the BOX and insulation of the Refer. SO, no access to check the wiring. There are no good ways to "test" an Eyebrow other than replacing with a new one and see if that fixes the problem. I have had just 1 Dometic in 30 years that had an internal eyebrow problem and that was under warranty. Unless you have had rodents chew up the box insulation and your box is in good shape, then the wiring will be OK. BTW, There is NO WAY your interior temp was 14 degrees. NO WAY. What type of Thermometer were you using? The CORRECT way to determine interion refer temp(not the freezer) Is leaving a small glass of water inside after the 24 hour test and measuring the water temp. RV refers, the FINS will be 10 degrees colder than the interior temp. So, for you to have 14 degrees would mean the fins were 4 degrees, 2 degrees warmer than the freezer temp. In 42 years as a RV tech I have NEVER seen a RV refer get colder than about 24 to 26 degrees. Doug
