CRITICAL SAFETY WARNING: This repair involves working inside the refrigerator with electrical components. Always unplug the refrigerator before beginning work to prevent electrical shock. If uncomfortable with this repair, hire a qualified technician.TOOLS REQUIRED: Phillips screwdriver, flathead screwdriver, flashlight, work gloves (optional).IMPORTANT: This thermistor is for the fresh food (refrigerator) compartment only. Freezer compartments use a different thermistor. Verify your sensor location before ordering.

1. Unplug the refrigerator from the electrical outlet to ensure complete power disconnection. CRITICAL: Never work on the refrigerator while it's plugged in.
2. Remove all food and shelves from the fresh food compartment to access the thermistor sensor location.
3. Locate the thermistor sensor in the fresh food compartment. Typically mounted on the back wall, ceiling, or inside an air duct near the top of the compartment. Look for a small white or gray plastic housing with wires leading to it.
4. Take multiple photos of the thermistor location, mounting configuration, wire routing, and connector position before removal. CRITICAL: Wire routing and mounting details must be exact for proper reassembly.
5. Trace the thermistor wires from the sensor to the connector. The connector typically plugs into the control board or a wiring harness inside the refrigerator cabinet.
6. Access the connector by removing any panels or covers necessary. Some models have the connector accessible from inside the fresh food compartment, while others require removing a panel inside the refrigerator cabinet.
7. Disconnect the thermistor connector from the control board or wiring harness by carefully pulling the connector apart. Caution: Do not pull on the wires—grip the connector body and pull straight. Note the connector orientation for reinstallation.
8. Remove the thermistor from its mounting clip or bracket. Most thermistors are held in place by a plastic clip that snaps onto the sensor housing. Gently squeeze the clip or pry it open with a flathead screwdriver to release the sensor.
9. Carefully pull the thermistor out of its mounting location, routing the wires through any clips or guides.
10. Inspect the old thermistor for damage indicators: cracked or damaged housing (moisture infiltration), damaged or cut wires (electrical failure), corroded connector pins (poor electrical connection), or visible moisture inside the housing. This confirms the diagnosis.
11. Test the old thermistor resistance (optional, requires multimeter): Set multimeter to measure resistance (ohms). Touch the probes to the two thermistor wires or connector pins. At room temperature (70°F), resistance should be approximately 10,000-12,000 ohms (10-12 kΩ). If resistance is infinite (open circuit) or very low (short circuit), the thermistor has failed.
12. Clean the thermistor mounting area with a cloth, removing any dust or debris.
13. Unpack the new WR01F01730 thermistor sensor from its packaging.
14. Compare the new thermistor to the old one to verify dimensions, wire length (18 inches), connector type, and overall design match.
15. Inspect the new thermistor for any shipping damage before installation. The housing should be intact with no cracks, and the wires should be securely attached.
16. Route the new thermistor wires through any clips or guides in the same path as the old sensor, following your detailed photos.
17. Position the new thermistor in the mounting location, ensuring it's oriented correctly for accurate temperature sensing. The sensor should be positioned to sense air temperature, not touching walls or components.
18. Install the thermistor into its mounting clip or bracket by inserting the sensor housing and snapping the clip closed. The clip should hold the sensor securely with no movement.
19. Verify the thermistor is securely mounted with no excessive play or movement. The sensor should be stable in its mounting location.
20. Route the thermistor wires to the connector location, ensuring wires are not pinched, kinked, or damaged during routing.
21. Connect the thermistor connector to the control board or wiring harness by aligning the connector and pushing it together firmly until it clicks or seats completely. Important: The connector must be fully seated for proper electrical connection.
22. Verify the connector is securely connected by gently tugging on the connector—should not pull apart.
23. Reinstall any panels or covers that were removed to access the connector.
24. Reinstall the refrigerator shelves in their original positions.
25. Return food to the fresh food compartment and arrange shelves as desired.
26. Restore electrical power by plugging in the refrigerator.
27. Set the temperature controls to normal operating settings (typically 37°F for fresh food compartment).
28. Run the refrigerator for 15-30 minutes to allow the system to stabilize and the control board to calibrate the new thermistor.
29. Monitor the temperature display (if equipped with digital display) to verify the temperature reading is reasonable (should show approximately 37-40°F for fresh food compartment at normal settings).
30. Check the compressor operation by listening for the compressor to cycle on and off normally. The compressor should run for 15-30 minutes, then stop for 15-30 minutes, cycling based on temperature.
31. Verify proper cooling by placing a thermometer in the fresh food compartment and checking the actual temperature after 2-4 hours of operation. Should be approximately 37-40°F.
32. Check for error codes on the display panel. If an error code appears (typically "FF" for fresh food sensor failure on GE models), the thermistor may not be properly connected or may be defective. Verify the connector is fully seated and try again.
33. Monitor for proper temperature control over the next 24 hours. The refrigerator should maintain consistent temperatures without excessive compressor cycling.
34. If the refrigerator maintains proper temperatures, displays correct temperature readings, and the compressor cycles normally, the repair is complete.

Safety Notes: Always unplug the refrigerator before working inside. Do not pull on wires—grip connectors. Verify the thermistor is properly mounted and the connector is fully seated. Test operation thoroughly before considering the repair complete. This repair requires minimal mechanical skills and typically takes 15-30 minutes for DIY.

1. The WR01F01730 is specifically for the fresh food (refrigerator) compartment—do not confuse it with the freezer thermistor, which is a different part number. GE refrigerators typically have two separate thermistors: one for the fresh food compartment and one for the freezer compartment. Each sensor has a different part number and different resistance values at specific temperatures. Installing the wrong thermistor causes incorrect temperature control in that compartment. Verify your sensor location (fresh food or freezer) before ordering. If your freezer is not cooling properly, the freezer thermistor may have failed—order the correct freezer sensor part number.
2. A failed fresh food thermistor causes the refrigerator section to warm up while the freezer remains cold because the control board receives no temperature feedback for the fresh food compartment. Without a temperature signal, the control board cannot activate the damper door or evaporator fan to direct cold air to the fresh food section. The freezer may remain cold because it has its own thermistor that's still functioning. If your fresh food compartment is warm but the freezer is cold, the fresh food thermistor has likely failed.
3. Thermistor resistance changes predictably with temperature—at room temperature (70°F), a typical GE fresh food thermistor reads approximately 10,000-12,000 ohms (10-12 kΩ). You can test a suspected failed thermistor with a multimeter: set to measure resistance (ohms), touch probes to the thermistor wires or connector pins, and note the reading. At room temperature, it should be in the 10-12 kΩ range. If resistance is infinite (open circuit, sensor broken), very low (short circuit), or doesn't change with temperature, the thermistor has failed. This simple test confirms the diagnosis before ordering a replacement.
4. The thermistor connector must be fully seated for proper electrical connection—a loose connector causes intermittent temperature readings or complete sensor failure. After installing the new thermistor, verify the connector is pushed together firmly until it clicks or seats completely. A partially connected thermistor causes the control board to receive intermittent or no temperature signal, resulting in erratic cooling or complete cooling failure. If the refrigerator displays error codes or has temperature problems after replacement, disconnect and reconnect the thermistor to ensure proper seating.
5. Moisture infiltration into the thermistor housing is the most common cause of thermistor failure in refrigerators. The thermistor is exposed to humid refrigerator air, and if the housing seal is damaged or the connector is loose, moisture can enter and cause resistance drift, open circuits, or short circuits. When replacing a failed thermistor, inspect the mounting location for moisture or condensation. If moisture is present, the refrigerator may have a humidity or defrost system problem that should be addressed to prevent repeat thermistor failure.
6. The 18-inch lead length on the WR01F01730 provides flexible routing for various refrigerator configurations—do not cut or shorten the leads unless absolutely necessary. The 18-inch length allows the thermistor to be mounted in optimal locations for accurate temperature sensing while providing enough slack for easy installation and maintenance. Cutting the leads reduces flexibility and may result in improper sensor positioning. If the lead length is too long, coil the excess wire neatly rather than cutting it.
7. Thermistor calibration drift from thermal cycling can cause gradual temperature control problems—if your refrigerator has been running for 10+ years with the original thermistor, replacement may improve temperature accuracy. Thermistors can drift slightly over time from repeated heating and cooling cycles, causing the control board to receive inaccurate temperature readings. This results in the refrigerator running slightly too warm or too cold. If your refrigerator is over 10 years old and has temperature problems, replacing the thermistor with a new, accurately calibrated sensor often restores precise temperature control.
8. If the refrigerator displays an error code (typically "FF" for fresh food sensor failure) after thermistor replacement, the connector may not be fully seated or the thermistor may be defective. Disconnect the thermistor connector, inspect the pins for corrosion or damage, and reconnect firmly. If the error code persists, the new thermistor may be defective—return it for replacement. Do not assume the control board is faulty without first verifying the thermistor is properly connected and functioning.
9. The control board uses the thermistor resistance to calculate temperature—if the thermistor is not positioned correctly, it may sense incorrect temperatures. The thermistor should be mounted in a location that accurately represents the average air temperature in the compartment, typically on the back wall or ceiling where air circulates freely. If the thermistor is mounted against a wall, inside a vent, or in a location with poor air circulation, it may sense localized temperatures that don't represent the overall compartment temperature. Verify the new thermistor is positioned in the same location as the old one for consistent temperature control.
10. Compressor cycling patterns change when the thermistor is replaced because the new sensor has more accurate calibration than the old one. After replacing a failed thermistor, you may notice the compressor cycles more frequently or for different durations than before. This is normal and indicates the control board is now receiving accurate temperature feedback and cycling the compressor correctly. If the new cycling pattern seems excessive (very short on/off cycles), allow 24 hours for the system to stabilize. If excessive cycling persists, the control board may need service.
11. The thermistor is a passive sensor—it requires the control board to send a reference voltage and measure the resulting current or voltage drop to determine temperature. If the control board is defective and not sending the reference voltage, the thermistor will not function properly even if it's new and properly connected. If you've replaced the thermistor and the refrigerator still has temperature problems, the control board may be faulty. Test the control board's voltage output at the thermistor connector with a multimeter to verify the board is functioning.
12. Always verify the refrigerator is cooling properly before considering the repair complete—allow 2-4 hours for the system to stabilize and reach proper operating temperature. A new thermistor won't show results immediately. The control board needs time to calibrate the new sensor and adjust compressor cycling. After 2-4 hours of operation, the fresh food compartment should be approximately 37-40°F and the freezer should be 0°F or below. If temperatures are still incorrect after 4 hours, the thermistor may be defective or the control board may have a problem.
