Yes, the "check light" will come on if there is an interruption of cooling to the refrigerator. That can be caused by the 120 VAC heater failing or by the propane system not functioning properly. If the refrigerator calls for cooling and the system in in the propane mode, it will attempt to light three times, If, at the third attempt, there is no propane flame detected, the "check light" will illuminate. Since you say there is no propane at the stove, that is probably why you have a "check light" on the refrigerator. Refill your propane, purge the lines (to remove all air) by turning on the stove burner until it lights properly, then turn the refrigerator back to propane. It may take 3 or 4 (maybe more) attempts before all the air is out of the gas lines and it functions properly, so don't give up after one try. Let us know what you find after you have propane available.....

ADDED: You must have 12VDC (either battery or converter power) in order for the refrigerator to operate properly. Even on 120VAC, the system control board must have 12VDC to operate. So, if your battery is low and you are not plugged into shore power, the refrigerator will not operate properly, even if you do have propane.
