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 240597220 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 a Genuine OEM part manufactured by Frigidaire/Electrolux to factory specifications. It is the exact same temperature sensor installed in compatible Frigidaire, Electrolux, Kenmore, Crosley, White-Westinghouse, Kelvinator, Gibson, Tappan, Viking, and Ikea refrigerators from the factory — guaranteed fit, materials, and performance.

DA32-00029X Genuine OEM Samsung Refrigerator Temperature Sensor The DA32-00029X is a Genuine OEM Samsung replacement refrigerator temperature sensor compatible with select Samsung side-by-side and French door refrigerators, as well as related Kenmore Samsung-built models. This NTC (negative temperature coefficient) thermistor continuously monitors the temperature inside the refrigerator and sends resistance-based readings to the electronic control board, which uses this data to cycle the compressor, fans, and defrost heaters to maintain accurate, consistent temperatures throughout the appliance. As the thermistor heats up or cools down, its electrical resistance changes predictably, allowing the control board to calculate the exact temperature in real time. When this sensor fails — whether shorted, open, or providing drifted/inaccurate readings — the refrigerator may run too cold or too warm, cycle excessively, fail to maintain set temperatures, run continuously, ice up the evaporator, or display temperature-related fault codes. As a Genuine OEM part manufactured by Samsung to factory specifications, the DA32-00029X is rated approximately 13.2 kΩ at 20°C (68°F) when functioning correctly. It is one of the variants in the DA32-00029 sensor family — Samsung uses different production-run variants (M, N, Q, U, X) across model generations, all functionally similar but with different wire harness connectors. Installs in 20–30 minutes with basic hand tools. Quick Answer The DA32-00029X Genuine OEM Samsung Refrigerator Temperature Sensor fixes Samsung side-by-side and French door refrigerators that run too cold or warm, cycle excessively, freeze up the evaporator, fail to maintain set temperatures, or display temperature-related fault codes. Genuine OEM Samsung NTC thermistor — approximately 13.2 kΩ at 20°C (68°F). One of the DA32-00029 series variants (M, N, Q, U, X) — confirm your specific variant by connector style before ordering. Common Problems This Part Fixes Refrigerator running too cold or too warm — sensor not accurately reporting temperature to the control board Inconsistent temperatures — fluctuating cooling that can't maintain set point Excessive or frequent defrost cycles — control board misreading temperature Refrigerator running continuously without cycling off Heavy frost or ice buildup on the evaporator coils caused by erratic defrost timing Food spoilage from temperature instability Temperature-related error codes displayed on the control panel Multimeter test shows 0 ohms (shorted) or infinite resistance (open) instead of the expected ~13.2 kΩ at room temperature Replaces Part Numbers This temperature sensor directly replaces the following Samsung part number: DA32-00029X, EAP16732853, FIX16732853, ASM30292, AP7188139, OEM21564426, PD00090960, PS16732853. The DA32-00029X is part of the broader DA32-00029 sensor family — variants M, N, Q, U, and X are functionally similar Samsung temperature sensors used across different model generations, but with different wire harness connector configurations. They are not automatically interchangeable — match the variant suffix (or the connector style) to your refrigerator. Contact our support team with your model number if you need confirmation before ordering. Compatibility This temperature sensor is compatible with select Samsung side-by-side and French door refrigerators, including: Samsung side-by-side refrigerators (select models in the RS-series with the matching DA32-00029X connector) Samsung 3-door French door refrigerators in 17.5 cu. ft., 19.5 cu. ft., and related capacities (Black Stainless Steel, Black, White, and Stainless Look finishes) Samsung 4-door French door refrigerators (select RF-series models with the matching DA32-00029X connector) Kenmore / Sears refrigerators (select Samsung-built models) Important — Match the Variant to Your Refrigerator: Samsung uses several variants of the DA32-00029 temperature sensor (M, N, Q, U, X) across different model generations. The sensors are similar in function and resistance value, but the wire harness connectors differ — using the wrong variant means the connector won't fit. Before ordering, verify your refrigerator's parts diagram specifies DA32-00029X (not DA32-00029M, N, Q, or U), or visually confirm the connector on your old sensor matches the new one.

Wear work gloves to protect your hands. Samsung refrigerators typically have multiple temperature sensors — fresh food compartment, freezer compartment, and evaporator/defrost sensors — confirm which sensor location matches your symptom and parts diagram before starting. The fresh food and freezer sensors are typically clipped to a wall or shelf bracket inside each compartment, while evaporator/defrost sensors are mounted near the evaporator coils behind a rear access panel. Take a photo of the sensor mounting and wire routing before removing. Disconnect the sensor's wire connector (gently — the molex connectors can be fragile) and release the sensor from its mounting clip. Inspect the connector for corrosion or heat discoloration on the wires — discoloration indicates prior overheating in that area. Install the new DA32-00029X sensor in the same position, reseat the connector firmly, and secure the mounting clip. Restore power, allow several hours for the refrigerator to return to its set temperature, and confirm stable temperature operation before reloading with food. Tools needed: Phillips screwdriver, multimeter (for testing), work gloves. Frequently Asked Questions How do I know if the temperature sensor has failed? Unplug the refrigerator, disconnect the sensor's connector, and set your multimeter to resistance mode. At room temperature (around 20°C/68°F), a working NTC thermistor should read approximately 13.2 kΩ. 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. Either reading confirms the sensor needs replacement. If the sensor reads close to 13.2 kΩ at room temperature but the refrigerator still has temperature problems, the control board or another sensor in the system may be the actual cause. My Samsung refrigerator has multiple temperature sensors — which one do I replace? Samsung refrigerators typically use multiple temperature sensors: one in the fresh food compartment, one in the freezer compartment, and one near the evaporator coils (often called the defrost sensor). The DA32-00029X is used as the fresh food or freezer compartment temperature sensor on select Samsung models. Confirm the exact mounting location for your specific symptom (e.g., fresh food too warm vs. freezer too cold) and your refrigerator's parts diagram before ordering. The evaporator/defrost sensor is typically a different part number, so don't assume the DA32-00029X covers all sensor positions. What is the difference between DA32-00029X and DA32-00029M, N, Q, or U? These are all variants of the same Samsung refrigerator temperature sensor family. They share the same NTC thermistor design and resistance characteristics (approximately 13.2 kΩ at 20°C), but use different wire harness connector configurations to match different refrigerator generations and wiring designs. The X variant is used on select Samsung side-by-side and French door models, while M, N, Q, and U variants appear on other model groups. They are not automatically interchangeable — match the variant to your refrigerator's exact part diagram, or visually compare connector styles before ordering. My Samsung fridge is icing up the back wall — could this be the sensor? Possibly, yes. If the temperature sensor near the evaporator (the defrost sensor) is misreporting temperature, the control board may not trigger the defrost cycle when needed, allowing ice to build up on the evaporator coils. Eventually this ice migrates to the rear interior wall as a frozen sheet. If your symptom is back-wall icing combined with poor cooling, the evaporator sensor is a likely cause — but confirm whether the DA32-00029X is the evaporator sensor on your specific model, or whether your model uses a different part number for that position. Always verify against your model's parts diagram. Is this a Genuine OEM or aftermarket part? This is a Genuine OEM part manufactured by Samsung to factory specifications. It is the exact same temperature sensor installed in compatible Samsung side-by-side and French door refrigerators (and Kenmore Samsung-built models) from the factory — guaranteed fit, materials, and performance.
