The thermistor in food section is sensing bulb that thermostat uses to determine run cycles in order to maintain food section temp.

Freezer temp.........lower the better.
The freezer section is the first evaporator (low temp evap)in the cooling process. When first cooling fridge the freezer uses up all the cooling until it gets down to roughly 10*F then food section will begin to cool.
When freezer temp is already cold there is more cooling action for the 'high temp evap' which is what thermostat controls

Not correct. The design of an Absorbsion unit, is such that the FIRST extremely cold CU coils are at the freezer. The unit coils then go down to the refer. The Freezer will in practical terms get the same cold(0 to 10 degrees) regardless of the tstat setting as there is NO tstat for the freezer. The design puts the extreme cold to the freezer first.

Aren't we saying the SAME thing :H

This is what you stated----"When first cooling fridge the freezer uses up all the cooling until it gets down to roughly 10*F then food section will begin to cool". The freezer does NOT get cold FIRST and then cools the lower. It does it all at the same time. It just takes longer for the lower to get to sub 40 degrees. Doug

OK........

Food section will be part of the whole cooling process but one will not 'FEEL' the cooling effect due to freezer section absorbing majority of cooling due to it being first in cycle/process.
Only so much cooling available.....based on amount of ammonia that can vaporize and condense back into liquid (which is what absorbs the heat from freezer/food evaps). More heat absorbed in low temp evap less available heat transfer can occur in high temp evap.
