Wear work gloves to protect your hands. Depending on your refrigerator model, the fresh-food temperature sensor is typically located behind the air tower or damper assembly on the rear interior wall of the refrigerator compartment; the freezer temperature sensor is typically located behind the rear freezer access panel near the evaporator coils. Confirm which sensor location matches your symptom and the parts diagram for your specific model before starting. Remove all shelves, drawers, and any items blocking access to the sensor location. Remove the screws holding the air tower/damper cover (fresh food side) or rear freezer access panel to expose the sensor. Photograph the sensor position, wire routing, and connector before removing. Disconnect the wire connector (gently — the connector can be fragile) and release the sensor from its mounting clip. Fully insert the new 240597203 sensor probe into the card slot (no exposure) and secure with the mounting clip. Reconnect the wire connector — plug wiring terminals tightly to avoid poor contact. Use cable ties to secure any loose wire routing as before. Reinstall the cover or panel, replace the shelves and drawers, and plug the refrigerator back in. Allow several hours for the refrigerator to return to its set temperature before reloading with food. Tools needed: Phillips screwdriver, cable ties, multimeter (for testing), work gloves. Frequently Asked Questions What does OP error code mean on my Frigidaire refrigerator? The OP error code (Open) indicates the control board is detecting an open circuit on a temperature sensor input — meaning the sensor is failing to send a resistance signal, either because the sensor itself has failed open internally, the wire has broken, or the connector isn't seated. Replacing the temperature sensor typically resolves the code when the sensor itself is the cause. If the code persists after replacement, check the wire harness between the sensor and the control board for damage, and confirm the connector is fully seated. If the OP code appears alongside other symptoms like frost buildup and cooling issues that persist after sensor replacement, the defrost temperature sensor (on the Harness-Low Side, a different part number) may also need to be replaced, or the main control board may be at fault. How do I test if the temperature sensor has failed? Unplug the refrigerator, disconnect the sensor's wire connector, and set your multimeter to resistance mode. At room temperature (approximately 25°C / 77°F), a working NTC thermistor should read approximately 10K Ohms. If the sensor reads 0 ohms, it has shorted internally. If it reads infinite resistance (open circuit, often shown as "OL" on the multimeter), the sensor has failed open. If it reads significantly off from 10K (for example 8.4K or 5K at room temp), the sensor has drifted and is no longer providing accurate readings — replacement is recommended. Any of these results confirms the sensor needs replacement. My refrigerator has multiple temperature sensors — which one do I replace? Frigidaire refrigerators typically use multiple temperature sensors: one in the fresh food compartment (behind the air tower/damper), one in the freezer compartment (near the evaporator coils), and often a separate defrost temperature sensor on the Harness-Low Side. The 240597203 is used as the fresh food or freezer compartment temperature sensor. If your symptom is "fresh food too warm" or "freezer over-freezing," the fresh food sensor is the likely candidate. If your symptom is "freezer icing up despite defrost heater working," the defrost temperature sensor may be the culprit — a different part number. Check your refrigerator's parts diagram to confirm the correct sensor location for your specific symptom. Does this sensor fit my Kenmore refrigerator? On many Kenmore refrigerators, yes — Sears sells Kenmore-branded refrigerators that are manufactured by Frigidaire/Electrolux, Whirlpool, LG, and Samsung. The 240597203 sensor fits Kenmore refrigerators with model numbers beginning with the 253, 106, or 795 prefixes that are Frigidaire/Electrolux-built. Kenmore refrigerators built by other manufacturers (Whirlpool, LG, Samsung) use different sensors. Check the first three digits of your Kenmore model number — if it's 253, 106, or 795 and falls within the compatible model list, this is the correct part. Is this an OEM or aftermarket part? This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Frigidaire/Electrolux OEM part, but is manufactured to match the electrical specifications (10K Ohm NTC), probe dimensions (5/16" diameter x 1-3/16" length), wire length (12"), and connector configuration of the original 240597203 temperature sensor used in compatible refrigerators.

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.
