How to Fix It
1
Identify which compartment (fridge or freezer) has the incorrect temperature to narrow down the faulty sensor
2
Unplug the refrigerator and locate the thermistor for the affected compartment (usually clipped to the evaporator or mounted on the compartment wall)
3
Disconnect the thermistor and measure its resistance with a multimeter (approximately 16k ohms at 32 degrees F, 5k ohms at 77 degrees F)
4
If the reading is far outside the expected range, replace the thermistor
5
Check wiring connections from the sensor back to the main control board
