Power cord is hot and fuses are good.
Lower circuit board.....bottom right side are 2 black leads that are for the heater element
They connect at J7 & J8
One is 120V AC HOT and other is Neutral/Common
Typically 'odd' are HOT and 'even' are Neutral/Grounds
So with Fridge in 'AUTO' and temp warm enough for thermostat to call for a cooling cycle....J7 should be HOT
Check resistance of element when measured at the 2 leads 44 ohms
Should have continuity when measured at the 2 leads

On Edit:
Flue warm.....element is 325W and should generate 350*F temps in order to boil the liquid ammonia into a vapor
IF element checks good
Then unplug fridge temp sensor leads (Thermistor)
Left side P2 connector....2 White leads
Run fridge for 12 hrs and check temps in freeze & food compartment.
Should be 10*F/lower in freezer and 38*F/lower in food compartment
This will test that cooling unit is functioning
