When cooling, both refrigerator and freezer cools OK but the unit will shut down completely while riding down the road and or when sitting still. I disconnected the P2 Thermistor plug from main circuit board, turned unit on, and after 12 hr, the freezer temp was -5f and the fridge temp was +22f. I then plugged the P2 Thermistor plug back into the main circuit board and the temp adjusted according to the setting 1 through 5.
Does this problem appear to be the Thermistor, Main Circuit board or something that I have not thought of yet? By the way, prior to disconnecting the Thermistor from the Main Circuit board, I could not get the unit to cool at all but the heating elements were heating correctly. Thanks for every ones help.
