For TESTING
*Unplug Thermistor (temp sensor) from Lamp connection
Run fridge for 12 hrs on MAX Temp Setting (9) and check temps
W/O Thermistor fridge goes into BOS (Backup Operating System) where heating cycles (heat ON) is time based vs temp based
If food compartment cools (might get COLD) then replace the Thermistor
IF still not cooling need to FORCE COOL Test
*unplug the 2 heat element leads from circuit board
Wire the leads directly into 120VAC Element energizing the elements continuously
Run fridge for 12 hrs monitoring (force cool bypasses ALL controls)
Check temps
Fridge COLD........replace circuit board
Fridge still not COLD.....cooling unit has failed (obstruction/blockage)
