I started my fridge today on the auto mode without the propane tanks truned on. The fridge would not start and the check light would turn on. I reset it and tried again three other times without any luck. Once I opened the valves to the propane tanks it started fine on auto. There is a propane gas only option that will run the fridge off the propane gas solely. I have four six volt batteries and have pleny of power on tap to run it solely on power. My question is in the auto mode do you have to have your propane gas on for it to work, or should it also work with just power and without propane gas? Thanks to all the give me info on this.

It is my understanding that the refer will only work with propane and 110v power ie. shore power, genny. The only way the refer will work w/ the 6 volt batteries is if there is an invertor that powers the electrical outlets.

X2, fridge only works on 12V & propane (most efficient) or 12V and 120V (Shore power, genny or a powerful enough inverter).

A Dometic refrigerator should work on 12V with propane, 110V, and some have a 12V function only. If you turned it on auto and didn't have it plugged into shore power, and the propane is turned off, you should get a check light. It's working fine in that case. If you had it plugged into 110V and it did it, you have another problem than propane.

Thanks fellas ^^^that's exactly what I did. So I'm glad to see that everything is working fine.
