Question Refrigerator not working on LPG though it DOES fire off

Dometic RM 3663 not working on LPG though it DOES fire off.

Hello my Dometic Refrigerator, RM 3663, works fine on AC but will not cool on LPG. It does oddly enough fire though... if you walk out side and have someone turn it on the burner it will ignite and burn for approx 30 seconds or so. I have not checked the fuel delivery, I think it is called column test or something like that for two reasons 1. all the other appliances seem to run normally on LPG and 2. I do not know the procedure to test it. I have checked grounds and fuses but to no avail. Any help here would be greatly appreciated. including the tools/testers and procedure needed to run LPG test.

Todd

In the burner "box" there will be a flame sensor. It will be at a point where the burner flame engulfs it. That sensor is what "tells" the control board to continue sending LPG to the burner. If it doesn't get hot enough the LPG is cut off and the flame goes out. That sensor could also be shorted to the burner by rust that falls down the flue pipe or is blocking the burner ports. My suggestion is to look at the burner....it probably needs to be cleaned.

I cleaned the electrodes, which really did not seem to dirty, but to no avail it still runs for about forty seconds and then it shuts the flame down.
Is there a way to test the electrodes or...

Thanks
Todd

Another thing to check is to look in the burner where the gas orifice is and check for spider webs. They will deflect the gas enough to make the flame erratic.

Thanks Kix & wackymac,

I appreciate the good advise.
It ended up that the Thermocouple was shot. New one in and works correctly again.

I also purchased a new Dinosaur P-711 board to replace the factory board (though I have not installed it yet as leaving it out is the only to prove that the Thermocouple was indeed the problem although I was only getting 10 to 11 millivolts out of it and you should get 25 to 30 now there is NO doubt) I intend to replace it next. From every thing I have been reading this is a good board that fixes many "check light" problems. Kix and any body else, I would appreciate your thoughts on this board and If you think it is a good move on part to go ahead and install this new Dinosaur board.
Thanks again
Todd
