            This has been a head scratcher. No one has seen this happen before so have not been able to resolve the problem.

My burner on the fridge gets a build up of some type of matter that starts at the igniter rod and grows to and makes contact with the thermocouple. Fridge runs ok until it is purposely shut off such as for cleaning then won't relight because it is now shorted between the ignitor and thermocouple.
Thought it might be something in the gas but I use the same gas supply for another camper fridge which burns clean.

This started a couple years ago and seems to be increasing its happening in a shorter time. Had to get up at 3am this morning to clean the stuff for re-ignition and 8 hrs later there was almost half the distance built up again see pic.
