Roughly every 48-49 hrs ....food compartment temp to 50*F
Timeline can be changed by when you turn fridge off then back on
*turn fridge off/back on at 11pm so 'frost management system' occurs at night vs hot time of day
Force Cool test
Turn fridge off, unplug AC Power cord, Unplug AC heater element leads from lower circuit board and plug them directly into the 120VAC Outlet
Elements remain energized Force Cooling fridge IF cooling unit is capable of function (no blockages)
****Bypasses ALL Controls so monitor closely during the 12hr test
First would be to unplug thermistor causing fridge to run w/o temp sensing. BOS (Backup Operating System)
Then if not cooling down move on to force cooling test
IF fridge cools down w/o thermistor....bad thermistor
If fridge cools down force cooling...then circuit board is the problem
If fridge doesn't cool down....cooling unit is toast
