Fridge Problem

I noticed on my last trip, that the fridge will not light and stay lit on propane. It runs fine on electric. When I switch to gas I can hear it click, as if it is trying to light, and then I hear what sounds like ignition, but it quickly stops and starts clicking again. In my opinion it sounds as if the igniter is working and lights the flame, but it simply can't stay lit. Their is plenty of fuel and all of the lines have been run so ther is no air inside. Any ideas or suggestions? Repair is a long ways away so I'm hoping to be able to solve it myself.

Check your burner tube for dirt dauber or spider nests.

Cocaseco:
You might also have a propane dealer check your propane pressure out of the regulator (the service manual specs 11 inches of water as a pressure spec). The service manual also shows a screwdriver slot valve under the gas solonoid. Is that turned all the way on?
The manuals are in the "Tools" section on the bar at the top of the forum pages.

Thanks. I'll investigate these suggestions.
