Pilot on but burner flame is flat

[Rob1966]

I have a '66 Caravel with original Dometic. Frig has worked for the past year. Now, the pilot lights with no problem, but the burner does not fire up. The burner glows blue but flat, without any arc. As a result, I think, the thermocouple is not heating up properly which causes the main valve to shut the gas off. Is this a gas pressure problem? Is the thermostat stuck in low? Do I need to clean-out the burner? Thanks in advance for any suggestions.

For me, and I had to do this like 3 times on the latest 5K trip over 2 months and just returned, you need to clean out the small apeture that goes into the valve itself. There are several threads on how to do this; but it really is just a matter of removing the tubing that goes into the valve upstream of the pilot light........Hope someone else will chime in with threads and more information......God bless......Dennis

Just did a search "refrigerator gas valve" and came up with LOTS of descriptions of what you need......:

Dennis, thanks again. I ended up disassembling and cleaning everything from the main valve through the burner. The burner was in pretty bad shape. But after soaking in denatured alcohol and freshening up with compressed air (twice), the flame is now standing tall and strong. I was a little surprised at how easy it was to take apart, clean, and reinstall the various components. Certainly not the chore I was expecting.
