AO airflow/draft is sufficient for removal of heat
AC Element and Propane transfer roughly the same heat energy to boil the ammonia coolant into a vapor

Dirty Burner assembly
OR LP System Pressure is Low (S/B 11"WC --0.4psi. IF low the flame temp will be low and heat generated will not boil the ammonia in sufficient volume to absorb heat from food compartment)
**10"WC is 0.36 psi....can not visually tell difference between 11"WC and 10"WC. Need a manometer to measure system pressure...with at least 50% of appliances in service

Had pretty much the same experience with our 1150 one time. Worked on AC, Fridge warm on propane. Looked at the burner and you could see it was noticeably smaller then normal. Was going to take it apart to clean the next day but it was working. Looked at the flame and it was burning brightly
