Propane flame is NOT hot enough to boil enough ammonia ----freezer section is using up all the available cold ammonia liquid and not enough absorption left to effectively cool food compartment & contents
Propane flame has to reach up into center of flue opening and transfer enough heat to flue baffle so that boiler section reaches 350*F-370*F to effectively heat the ammonia into a vapor
High altitude causes an air lean/fuel rich flame which results in cooler temps generated
Fuel rich conditions create soot which can insulate and resist heat transfer
Do a thorough clean of burner slots, gas orifice and especially flue/flue baffle
