SO YES if the flame is going it should be cooling. IF it cools on AC power but NOT LP many things can be eliminated.

SO right off the bat I would have the LP pressure tested, if the pressure checked. IF the pressure was low then the fridge may not cool very well or at all. This would require a manometer at the back of the fridge to check the pressure. In the shop it is a 30 min check.

I would also make sure the flue canister is clear and clean and that the canister is not at fault, you should have heat going up the flue canister to the top. If that canister was obstructed in the area that is below the heating element then it might not cool. Try and get an air nozzle and rubber hose and run it into the flue and give short bursts of air to clear it.

What you can also try is go to the circuit board outside and unplug the two wire connector and try running it on LP, that is the thermistor and when you unplug that the fridge should default to full cooling. IF it cools unplugging the thermistor then I would replace it. It plugs into the P-2 connector on the board.

The key is that it works good on AC power so to start I would advise to have the LP pressure checked to start...

Hope this helps some, IF you have more questions or concerns please feel free to contact me. IF you are satisfied with my efforts please feel free to select a STAR rating on the page..

I just checked the water heater on gas. It runs for 2 or 3 seconds and then shuts off. Is that due to low LP pressure?
