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

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. Contact our support team with your model number if you're unsure.

Installation Notes
⚠️ Unplug Refrigerator and Move Perishable Food Before Starting — Wear Work Gloves Unplug the refrigerator and safely store any food that could spoil while the power is off. 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.
