When the power went off, with the fridge on auto, it tried to light the gas burner. Since the propane was off, of course this failed. When it has tried 3 times, the check light comes on and it will no longer try to light the burner. You have to reset it by turning the power switch off then back on. However, this only applies to the gas. So when the power came back on, the fridge started cooling again on electric power. So it really was only off for as long as the electricity was out. Turning it off then on reset the gas, and turned out the check light.
