Fridge in new camper not working...
I picked up my new 2019 Arctic Fox 992 truck camper on Saturday morning. The fridge was working great on 110 while I was there. Once underway and on propane, every time I stopped, the fridge was b...

There are too many possible issues but the main ones
Propane on? Tank FUll?
When on propane. the t-stat calls for cool (Heat actually but I'm not going there) the control board sends about 1000 volts AC to the sparker and opens the gas valve. a short time later it shuts of the 1000 volts and looks for power returning from the thermocouple. about 0.48 volts or rather the current generated by 0.48 volts into the load the sensor chip presents... (Got in an argument on that once.. voltage into a resistive load = current so you can use either term).
Now imagine the switch from SPARK to SENSE gets flubbed. the poor sensor chip, expecting as it is about 1/2 volt. gets socked with 1414 volts peak...... Not good. Not good at all.
That means a failed control board.. Happened to my Furnace (Same ignition sequence) I put in a Dinosaur board.. the DINO board is protected from that flub.
