How to Test a General Electric (GE) Fridge Thermistor – Method 1

Without temperature sensor (thermistor) removal

1. Unplug the Refrigerator
   • Always start by disconnecting power to avoid electric shock
2. Locate the Main Control Board
   • In most General Electric (GE) fridges the main control board is usually located behind a cover on the backside of the refrigerator cabinet
3. Locate the Thermistor Connections on the Main Control Board
   • See the appropriate image below for reference
   • Check your model’s tech sheet or service manual for more information
4. Set Your Multimeter to Ohms (Ω)
   • Select the kΩ (kiloohm) resistance range if it’s not auto-ranging
5. Measure Resistance at Room Temperature
   • Disconnect the thermistor connector from the control board
   • Testing is done from the connector not the control board
     • DO NOT INSERT PROBES INTO THE CONNECTOR TERMINAL
     • This will damage the connector and cause a poor connection
   • Touch one meter probe to the outside of the common connector terminal
   • Touch the other meter probe to the outside of the thermistor connector terminal
   • Compare the reading to the appropriate chart based on the actual compartment temperature
6. Test in Ice Water for Accuracy
   • Submerge the thermistor in a cup of ice water for 5 minutes to simulate a 32°F environment
   • Touch the meter probes to the thermistor connector terminals
   • Compare the reading to the appropriate chart based on a temperature of 32°F

How to Test a General Electric (GE) Fridge Thermistor – Method 2

Requires temperature sensor (thermistor) removal

1. Unplug the Refrigerator
   • Always start by disconnecting power to avoid electric shock
2. Locate the Temperature Sensor (Thermistor)
   • In a General Electric (GE) fridge temperature sensors (thermistors) are usually clipped to the evaporator coils or mounted inside the fresh food or freezer compartments
   • Check your model’s tech sheet or service manual for more information
3. Remove the Temperature Sensor (Thermistor)
   • You may need to remove a panel to access it
   • Disconnect the temperature sensor (thermistor) from the wiring harness
     • If there is no connector you will need to cut the harness
     • Be sure to leave enough wire on the main harness to reconnect
4. Set Your Multimeter to Ohms (Ω)
   • Select the kΩ (kiloohm) resistance range if it’s not auto-ranging
5. Measure Resistance at Room Temperature
   • Touch the meter probes to the thermistor wires
   • Compare the reading to the appropriate chart
6. Test in Ice Water for Accuracy
   • Submerge the thermistor in a cup of ice water for 5 minutes to simulate a 32°F environment
   • Touch the meter probes to the thermistor wires
   • Compare the reading to the appropriate chart based on a temperature of 32°F
