68 Dometic Fridge

Hello everyone my name is Bob Mongiello I am a new member to this wounderful site. I have just bought my first Airstream a 68 Overlander 26 D and am in the prosses of restoring it as much as I can. I have replaced the entire water system, which was a combination of copper and hoses all clamped together, with a piping called Kitec and it is doing great. My question is with the Dometic fridge and the gas part of the system. It works great on AC so I know the Evap part is functioning, but the gas part is what's giving me trouble. I have removed it from the cabinet and inspected the flue pipe and found it to be totally rusted out so I found a piece of steel pipe that fit perfectly inside the old flue and installed it. The spiral baffle also fits great. I blew out the burner with compressed air and reinstalled it back in the cabinet, hooked it up and and fired it up. The flame was only about 3/4 of and inch long when it fired and did not change when I turned up the T-stat, I let it run for 18 hours and it did not get below 60 degrees F. Was woundering if anyone could give me some advise on this?
Thanks Bob

Bob,

The size of the flue and the positioning of the spiral baffle are CRITICAL to proper operation on LP. If the baffle is even a little off on ID or length and the baffle is not exactly positioned as the original, that could be the cause of your problems.

Also, your burner nozzle may be clogged and should be cleaned. Don't put anything thru it! Just soak in carb cleaner and blow it out with air. That might solve your flame problem. You should also check the pressure at the gas valve (11" water guage) and blow out the line from the valve to the burner. It might be fuel starved due to a blockage, or bad gas valve pressure.

Not sure if you have a thermostat or thermistor on that unit. It should be clamped on to one of the fins in the top/rear of the fridge section. Check in your manual and see if they list a test for it. The newer ones have you put it in a glass of ice water and then check the millivolt output. Yours might be a resistance value instead. Not sure without more research.

If the unit is cooling on 120VAC, then the above point is moot as it is functioning properly and your problem lies in the LP delivery/burner system.
