Our Dometic started going out. We replaced the circuit board, then added an adjustable thermister. It will cool off, then gets hot again.

check your 12 voltage.

I.E. thermostat needs constant 12 volt to turn on. If your fridge works than goes warm means the thermostat shut off at the desired temp but can't turn back on because of low 12 volt.
