Okay, I unplugged the 50 amp cord, shut off the invertor and all the lights....as soon as the 12 power is applied the fridge propane burner ignites.
There is now no response from the optical control for ON/OFF. The rest of the controls respond ie: temp, modes. It appears to likely be the "optical control" or "control board" that is malfunctioning.
For the immediate...as long as the fridge works sufficiently, I am just going to unplug the 12 volt when it is stored. Future plans are to replace with a Samsung.
Thanks for all the replies.
