Hi my name is Robert...

First thing that comes to mind on this is the LP pressure, that is if it is cooling good on AC power. This would be hard for you to do without a manometer, anytime the fridge is cooling on AC but not LP the pressure should be checked at the back of the fridge to make sure it is not low. A manometer is used to check the pressure, I understand the other appliances might be working fine but if the pressure was even a little low it could affect how well the fridge cools off. I might also pull the gas orifice and soak it in alcohol. I would also verify the thermistor is good. Make sure the flame is also in the center of the flue tube, make sure the flue cap and flue baffle are properly installed. Click HERE for a service manual so you can verify your wiring, the diagrams are on the last few pages. I doubt the cooling unit is at fault if it is cooling on AC power. IF all your checks are good it could be the lower circuit board. What you also could do is unplug the thermistor inside the box and run it on LP and see if it defaults to full cooling. Hope this helps some, IF you have more questions or concerns please feel free to contact me... Robert
