The thermistor location varies by model — it is typically clipped to a bracket on the interior side wall of the fresh food or freezer compartment, or mounted near the evaporator coil. Consult your model's parts diagram or service manual to confirm the exact location before disassembly. Open the sensor cover or unclip the sensor bracket, disconnect the wiring connector, and pull the old thermistor out. Insert the new 2188820 thermistor, reconnect the wiring connector, and snap the cover or bracket back into place. Ensure the sensor head is positioned close to the compartment wall and the wiring is not pinched. Restore power and monitor the refrigerator temperature over the next few hours to confirm stable, accurate cooling. Tools needed: Phillips screwdriver (for panel access on some models); no tools needed for sensor replacement itself. Frequently Asked Questions What is the difference between 2188820 and WP2188820? These are the same thermistor. WP2188820 is the updated Whirlpool OEM part number that superseded the original 2188820. The 2213442 is also a cross-reference for the same part. This aftermarket replacement is compatible with all three numbers. What does an NTC thermistor do and how do I know if mine has failed? An NTC thermistor is a resistor whose resistance decreases as temperature increases. The control board sends a small voltage through the thermistor and measures the resulting resistance — a lower resistance means warmer temperature, and a higher resistance means cooler temperature. The board uses this reading to decide when to run the compressor and fans. A failed thermistor either reads open circuit (no continuity), short circuit (zero resistance), or provides incorrect readings that cause the refrigerator to run too warm, too cold, or cycle erratically. Test with a multimeter at room temperature — a working 2188820 should read approximately 50K ohms at 25°C (77°F). Significant deviation indicates failure. How do I know if my refrigerator uses the WISE system? The WISE (Whirlpool Intelligent Smart Energy) system was introduced on newer Whirlpool refrigerator models and uses a different thermistor specification that is not interchangeable with the 2188820. Models that use the WISE system are typically marked in the product documentation or on the control board. The easiest way to confirm compatibility is to verify your model number with our support team before ordering, or check whether WP2188820 appears in your model's official parts diagram. If your parts diagram lists WP2188820, this replacement is compatible. Where is the thermistor located in my refrigerator? The thermistor location varies by model and brand. On Whirlpool and KitchenAid models, it is commonly found on the interior side wall of the fresh food compartment clipped to a plastic housing. On some models it is located near the evaporator coil behind the freezer back panel. On Kenmore 106 series models, it may be on the fresh food section wall or inside the back panel. Consult your specific model's parts diagram or search for a model-specific installation video to locate the sensor before disassembling the refrigerator. Is this an OEM or aftermarket part? This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured with an NTC thermistor rated to the same 50K ohm specification as the original WP2188820 to match the performance and accuracy of the factory sensor.

Remove all food and shelving from the freezer compartment. Remove the freezer bottom drawer and the back panel screws (typically 2 hex-head screws). Slide out the back panel to expose the evaporator coils and defrost heater assembly. If the coils are covered in frost or ice, use a hair dryer to melt the ice before removing the heater — do not chip or force the heater free while iced over, as the glass element is fragile and will break. Disconnect the heater wires from the wiring harness — note the orientation before disconnecting. Remove the 2 Phillips screws securing the heater bracket and lift the heater assembly out. Install the new WR51X10055 heater assembly in the same position, reconnect the wires, and reinstall the bracket screws. Reinstall the back panel, shelving, and food. Restore power and verify the defrost cycle operates normally. Wear work gloves throughout — the evaporator area has sharp edges. Tools needed: Phillips screwdriver, 1/4" nut driver, hair dryer (if coils are iced over), work gloves. Frequently Asked Questions What does the refrigerator defrost heater do? Modern refrigerators use an automatic defrost system that periodically runs a defrost cycle — typically once or twice a day — to melt frost that accumulates on the evaporator coils during normal operation. The defrost heater is a glass quartz heating element that energizes during this cycle and melts the frost off the coils. This keeps the coils clear so air can flow freely through them to cool the refrigerator. When the heater fails, frost builds up unchecked on the coils over days or weeks — eventually blocking airflow completely and causing both compartments to warm up, even though the compressor is still running. How do I know if my defrost heater has failed? Remove the freezer back panel to expose the evaporator coils. If the coils are heavily coated in frost or solid ice — especially if both the freezer and refrigerator sections have been warming up — a failed defrost heater is the most likely cause. You can confirm with a multimeter: disconnect the heater and probe both wire ends. A working heater shows continuity (resistance between approximately 10–200 ohms at room temperature depending on wattage). No continuity confirms the heater element has burned out. Also visually inspect the glass tube — a burned, blackened, or broken tube is a clear sign of failure. Should I also replace the defrost thermostat and temperature sensor? Yes — since the freezer must be fully emptied and the back panel removed to replace the heater, it is highly recommended to also replace the defrost thermostat (WR50X10068) and temperature sensor (WR55X10025) at the same time. All three components form the defrost system and wear at similar rates. A failed thermostat or sensor can cause the heater to run too long or not at all — replacing all three in a single repair eliminates that risk and saves you from another complete freezer teardown in the near future. My freezer is warming up but the compressor is running — is it the defrost heater? It often is — but not always. A compressor that is running but not cooling can be caused by a failed defrost heater (frost blocking airflow), a faulty evaporator fan motor (air not circulating), a defrost thermostat or timer failure, or a sealed system problem (refrigerant leak or compressor issue). The easiest way to distinguish a defrost system failure from other causes is to open the freezer and check whether frost has built up on the back panel or coils. If yes, the defrost heater is the most likely culprit. If the coils are clear and the compressor is running, look at the evaporator fan or sealed system next. Is this an OEM or aftermarket part? This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured as a single quartz tube glass heater rated at 120V/725W to match the dimensions and performance of the original WR51X10055 defrost heater assembly.
