Your fridge does not use a compressor in either mode. It uses heat transfer.
The only question is what provides the heat; Propane fire or AC heater elements.
Thus if your until does not cool with AC available, you must check the AC circuit breaker in the power center first. Remember even if AC is available to provide the heat; 12 volts DC from the battery or power converter is needed to run the control panel and light the little light in the fridge.
If the "AUTO" button is "IN" the fridge is "ON"; as long as the "GAS" button is NOT pressed in.
In AUTO without the gas button pressed in (NORMAL OPERATING MODE) the unit will cool if AC and DC is available. If AC becomes "not available" for what ever reason, AND 12 VDC is available, the unit will ATTEMPT to cool via burning propane. If the fire will not light, the "CHECK" light will come on. That is the ONLY way for the CHECK light to come on.
NO FIRE FROM A GAS LIGHT ATTEMPT.
So, for fridge that does not cool on AC
1) check DC fuse in panel. (or open door and see if light works)
2) check and RESET AC circuit breaker in power center
3) Check with socket tester where fridge plugs in behind white cover (to be sure there is power there)
4) Unplug and replug fridge into socket
Obviously fridge runs on propane, because you ran it out. The issue is why it won't run on AC.
