Fridge acting strange ?

Well at first my fridge would not run on electric so I ran on LP . When I got home I shut everything down unhooked battery then after a bit hooked it back up and fridge worked on electric. I left plugged in for 3 days on electric ,now it's back on LP and still plugged in. When it wasn't working on electric I got the flash code for AC thermal heater both times. Wondering how it started working all of a sudden and then just stopped ? Just wondering if anyone else experience this issue ?

I'm not sure what "the flash code for ac thermal heater" means. On ours, if you operate it on LP and the refer fails to light after a few tries (3 I think) then the gas light starts to flash to indicate the failure to light. If in the "AUTO" position with no shore power the same thing might happen as the refer switches to LP automatically.

If it's just not firing up on the propane then you need to make sure the valves are on, tanks have gas and the lines are purged of air.

Could be just a poor electrical connection. Try opening up the outside cover, then unplug and plug back in all electrical connectors you can find, especially the connection(s) on the circuit board. I believe there is a cover that needs to be removed to access the circuit board.

Pull the outside cover and check to see that the 120V cord is plugged in behind the fridge.

Then check the circuit breaker.

After that, the glass fuse on the back of the fridge.

Then the controller board is suspect.
