Freezer is FIRST in the cooling process
Freezer gets cold then food compartment can start cooling PROVIDED sufficient ammonia is being boiled into vapor
See the Hot vapor condenses into liquid as it flows thru Condenser at top of frduge
Then when it interacts with the Hydrogen Gas it becomes super cold which then absorbs the heat thru the Freezer EVAP Coil and then onto food compartment Evap Coil
IF NOT enough ammonia is boiled into vapor then not enough vapor condenses into liquid then not enough COLD liquid is available to absorb heat from BOTH compartments
Dirty Burner/Orifice....spide webs etc WILL disrupt the air/fuel mixture resulting in poor flame temps
LOW LP System Pressure will directly result in low flame temps
Low flame temps...flue baffle will NOT transfer sufficient heat to boil ammonia in volume needed to absorb heat.
AC Element is hot enough ...cooling unit is functional
Propane flame...not hot enough
