Dometic Frig RM3962
My Dometic Frig (2018 30 Classic) will not cool below 44 degrees F on setting 5. Freezer is fine will get down to -5 on occasion. I have checked the door seals, checked the amperage on the heater, installed fans inside, checked the thermistor and the resistance is good based on the published charts. I can't really find anything wrong but it does not want to go any lower. One thing I do see wrong is the eyebrow temp indicator registers about 10 degrees higher than the actual frig temperature. I suspect the frig is cycling on and off too often but don't have a clue how to test that. Every time I check the amperage on the heater the heater is on.
I am checking the inside temp with glasses of water with a high quality thermometer +-.5 degrees. So I am confident of the inside temp reading.
Any ideas?
