Dometic Alwasy Runs On Propane?
I just realized I've been running my Dometic fridge on propane when I camp even though it should be running on AC when I'm plugged in. AC is plugged in. Propane tanks are on. Dometic switch is in...

The fridge always requires propane to operate, but switches between 12V and AC.
So if I am hooked to AC the auto will choose the AC.
If the AC isn't hooked up the auto will choose DC.
Regardless it will always use propane?
No.
First off, there is (usually) no DC mode in these fridges, only AC, Propane and Auto. Few have DC mode, but most of them don't.
Assuming everything is wired as it should -
If you switch to AC, it will run on AC only. Propane will not be used.
If you switch to Auto, it will choose either AC or propane. Better don't use the Auto.
If you switch to Propane (or Gas, or whatever is written on the panel), it will work on propane and will also draw some DC from battery to operate the thermostat. In absence of Dc (low battery, for example) it will attempt to fire up propane, you'll hear ignition clicking a few times, and then it will display error message.
