odd refrigerator issue, Dometic

1. I doubt when it IS working you are getting 20 degrees in the refer. RETEST the operation. The ONLY valid temp measurement is the temp of a glass of water after 24 hours. In 38 years as a tech, I have NEVER been able to get an RV refer below 25/26 degrees and that is with the Tstat bypassed.
2. HOW are you measuring the temp? With a glass of water or just laying a Thermometer inside?
3. The Correct temps should be BELOW 10 degrees in the freezer and below 36 to 38 degrees in the refer. LOWER temps in the refer are more common----28 to 32 degrees.
4. How old is the refer and are you the original owner?
5. The correct way to measure the performance of a refer is to run the 120 element direct, bypassing any controls for 24 hours. That will tell you the state of the cooling unit. Doug

laying the thermometer on the top rack, I get 22degrees, running on gas... I havent actually took a good reading of the thermometer when on AC...

there is no testing of a glass of "water" at 22 degrees, but I could check to see what happens by setting the thermometer in a glass of water and then checking the internal temp of the glass of ice in about 12 hours.

when it is working, and with the thermostat turned down, it only takes about 5hrs for the fridge compartment to come to freezing from 70 degrees.... I have not checked to see what the freezer temp is, but it is definitely cold...

the unit is an '07, and I am the second owner.. the entire trailer was used very little before I purchased it and was just setting for the past 6 years without any use at all..

the reason I have not tested the unit directly at the ac element and bypassing the controls is because when its working and cooling, it can work for WEEKS just fine on AC or gas, which tells ME the cooling unit is capable of doing what it is supposed to do...

I will be checking the venting and the thermostat connection to the board today..
