Likely Causes
How to Fix It
1
Unplug the refrigerator and locate the affected temperature sensor (fridge or freezer section)
2
Disconnect the sensor and measure resistance with a multimeter (compare to the temperature-resistance chart in the service manual)
3
If the resistance is significantly higher than expected for the current temperature, the sensor is faulty
4
Check the wiring connections for corrosion that could add resistance to the circuit
5
Replace the temperature sensor if the reading is out of specification
