How hot should refrigerator be on the back side? absorbtion fridge. I had it out, testing it, and plugged into 120. The top of the coil , before fins, was way too hot to touch. Fridge works a...

Boiler section runs 325*F to 350*F when on electric or gas
Top pipe (water separator) that goes above condenser fin section is roughly 300*F+
Condenser causes the Hot ammonia vapor to cool into a liquid ammonia
When the liquid ammonia mixes with the Hydrogen it sub-cools which then absorbs the heat from freezer first (low temp evap coil) then from food compartment second (high temp evap coil...when the freezer is cold enough to allow heat absorption from food compartment)
Absorber tubes (large slanted tube bundle) should be warm to touch ---also absorber tank but less warm then tubes
Actual temperatures of the various components is a secret cause other then boiler (perk tube) operating temps no actual temps are published for general public
CAUTION:
Removing an absorption fridge and running it w/o being inside a cabinet with proper clearances WILL cause OVERHEATING conditions and damage the cooling unit
They are NOT designed to operate standing alone cause airflow/Draft is not present!
Not surprised yours was HOT!
