The DA32-00011C is the genuine OEM temperature sensor for Samsung RM255 series refrigerators. The temperature sensor (thermistor) monitors the internal temperature of the refrigerator compartment and sends resistance readings to the main control board, which uses this data to cycle the compressor and maintain the set temperature. When the sensor fails or drifts out of calibration, the refrigerator may run too warm, too cold, cycle erratically, or display temperature error codes. This sensor is a direct OEM replacement that restores accurate temperature monitoring and stable cooling performance.

Temperature sensor failure on Samsung refrigerators typically presents as a gradual drift — the fridge becomes slightly warmer over time, or the compressor runs more frequently than normal. A failed sensor can also cause the control board to misread temperature and over-cool, resulting in frozen food in the fresh food compartment. Before replacing the sensor, verify the failure with a multimeter: measure the sensor's resistance at room temperature (approximately 20°C / 68°F) — a working DA32-00011C sensor reads approximately 5,000–6,000 ohms. An open circuit (OL) or a reading far outside this range confirms sensor failure.

✓ Installation Tips

Disconnect power before beginning this repair. Repair difficulty: 2/5. Estimated time: 15–30 minutes. The temperature sensor is typically clipped to the evaporator coil or mounted in the refrigerator compartment wall, depending on the model. To access: remove the interior rear panel or evaporator cover (usually held by screws under a trim strip). Unplug the sensor connector, unclip the sensor probe from its mounting bracket, and install the new sensor in the same position. Reconnect the harness, replace the panel, restore power, and allow 2–4 hours for the refrigerator to stabilize before assessing temperature performance.

✓ Frequently Asked Questions

How do I test my temperature sensor before replacing it? Use a multimeter set to resistance (ohms). Disconnect the sensor connector and measure across the two sensor terminals. At room temperature (~20°C / 68°F), a working DA32-00011C reads approximately 5,000–6,000 ohms. An open circuit (OL) or a reading far outside this range confirms the sensor has failed. See our Refrigerator Not Cooling guide for a full diagnostic walkthrough.

Could a bad temperature sensor cause my freezer to be cold but fridge too warm? Yes — if the fresh food compartment sensor fails, the control board may not cycle the damper or compressor correctly for that zone, resulting in a warm fridge while the freezer remains cold. See our Fridge Too Warm, Freezer Cold guide for more diagnostic steps.

What is the difference between OEM and XPart sensors? The OEM sensor is the genuine Samsung factory part with certified resistance characteristics. The XPart sensor is a premium aftermarket replacement manufactured to meet OEM specifications. Both are direct plug-in replacements. XPart is not affiliated with Samsung. See our Refrigerator Not Cooling But Freezer Works guide for additional context.

Is this a difficult repair? Rated 2/5 difficulty. The sensor is accessible after removing the interior rear panel and all connections are plug-in. Most repairs take under 30 minutes. Contact us if you need model-specific guidance on locating the sensor in your RM255 model.
