If you have 120vac to the outlet behind the lower vent cover (plug something into it like a light so you can easily see that power is there)...then you should see a black box on the back of the fridge. 120vac and 12vdc go into this black box. 12vdc comes out to the gas valve, one high voltage cable comes out to spark the propane into flame when running off propane, and cables come out to the 120vac heater/s for running off ac. The cover will need to come off to see the fuses. There is one for 12vdc, which in your case is good, and one for 120vac. The cover tells you the amperage needed, if that fuse is blown. By the way, it is common practice not to connect fridges to gfci circuits since they sometimes go off for no apparent reason. John
