my dometic a/c runs fine during the day but shuts down at night. i can get it going again by turning the thermostat off then back on. it will run for several minutes then shut down again. i've noticed that when it does the compressor and fan shut down at the same time. i'm thinking that when it is working right, the compressor shuts down then the fan a few seconds later.
the control board has been replaced and the thermostat inside replaced.
problem seemed to disappear for a couple months but returned.

i have read other post about the same problem with their dometic a/c but have not read of a solution.

at present, it gets into the 60's here at night but the inside temp is above 70.

One thing you need to check. Do you have a cold air vent blowing on the wall tstat? That would cause shut down especially at night. Also, the separator plate between the Air Intake and the cold air exhaust needs to be checked and make sure there is no bleed over. THAT also would be a factor at night. Doug
