Refrigerator problem when running on propane

[Chip999]

Hello, just looking for some idea/thoughts on this problem-

2013 Cougar Xlite 29 RET. When the frig is on propane, it will initially light and the gas will burn. Then the ignitor will go again, trying to relight the already burning propane, until it shuts itself off and the check light comes on. Other times we will be set up and it will work for extended periods, but randomly will once again try to light an already lit burner, until the check once again comes on. I did take off the maintenance hatch and the tube cover and blew it out with air, at the recommendation of the tech, but the random problem persists. Any thoughts? It is under warranty and I have a July 21 appt, but if it could be something else that I could square away before an 80 mile trip to the dealern I'm willing....

Thanks!

There is a sensor in the blue LP flame. Sometimes there is something that builds up on that and prevents it from detecting that the flame is on. I would guess that either the sensor has build up on it or that it is broken.

Thanks Tom. I thought it may be that thermofuse. Since its under warranty we are running it in.
