Headed out this weekend to discover the fridge in our '94 (it's been replaced 5 years ago with a new one) would not shift from AC to gas when the shore power was stowed. Meaning no refrigeration as we travelled.

Switched it successfully to gas once we reconnected to shore power. Noticed the batteries are only producing a dim 12-volt lighting.

Theory: There's not enough juice in the batteries to successfully power-up the solenoid that lights the gas when it's relying on the batteries only.

Make sense? Need new batteries? Your thought is appreciated!

If you have been plugged in, the batteries may well be dry. They tend to overcharge and lose water in hot weather. Once dry, they are pretty much toast. I check mine every few weeks in hot weather.

Yes, you need 12 VDC to power the fridge circuit board, gas valve, and igniter. As you discovered, without 12 volts, the fridge will not work on gas. Once you were connected to your TV, you should have been able to run the fridge on gas.
