Another Dometic refrigerator problem

I hope some one can help. My rm2852 dometic refrigerator on cools on electric. I an hear and see the igniter cycle and I have seen it light the burner but as soon as the igniter stops clicking the burner turns off. A few year ago I replaced the circuit board and I recently cleaned the burner tube. It could be one of those electrical thing on that long tube but a hint would sure be appreciated.

That sounds like the thermocoupler. It should be a metal looking pencil in the area of the ignition point. It ether got knocked out of position when you cleaned the tube or is simply went bad. It should be a cheap fix.

Something like this: but make sure you get the one for your model


* Thermocoupler is a fancy word for flame sensor. It detects the heat change to validate the flame is lit to prevent the system from dumping gas and blowing up.
