DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM is a temperature sensing component supplied as an original-equipment part for Samsung refrigeration appliances. The designation describes a 5 V-referenced temperature sensor assembly-typically a thermistor-style element or integrated temperature sensor packaged with a specific connector and lead/color coding (yellow, two-pin) for plug-and-play replacement. As an OEM unit,it is intended to match the mechanical mounting,electrical interface,and temperature response expected by the appliance control electronics.
Inside the appliance the sensor provides real-time temperature feedback to the main control board and is commonly used in evaporator or defrost control circuits.The control board reads the sensor signal (usually as a resistance- or voltage-based input referenced to a 5 V supply) and uses that details to manage compressor cycling, evaporator fan operation, defrost heater activation, and other temperature-regulation functions. The sensor therefore interacts with power and signal wiring, the control board analog-to-digital input, and the defrost subsystem; its accuracy and placement directly affect defrost timing, temperature regulation, and fault detection.
In this article readers will find a technical overview of the sensor’s intended function and typical electrical characteristics, guidance on model compatibility and how to identify the correct replacement, common failure symptoms and diagnostic checks (including resistance-versus-temperature measurement, connector and harness inspection, and verification of 5 V reference and signal continuity), and practical considerations for replacement and validation after installation. The aim is to equip technicians,engineers,and appliance owners with the information needed to diagnose sensor-related faults,determine whether the DA32-00024V is the appropriate part for a given repair,and perform reliable troubleshooting and replacement while respecting electrical and mechanical constraints.

Function and Role of the Temperature Sensor in Refrigeration and Defrost Control
The DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM is a thermistor-type temperature sensor used in Samsung refrigeration evaporator and defrost circuits. It provides a temperature-dependent resistance that the control board reads against a 5V reference,so the board can time or terminate defrost cycles and regulate compressor operation. physically the part is designed to match Samsung harness and mounting locations (the yellow lead and connector indicate the intended OEM fit), and electrically it typically forms one leg of a voltage divider feeding an ADC or comparator on the main control board to translate temperature into a voltage signal the controller expects.
In normal operation the sensor’s resistance changes predictably with temperature (NTC behavior: resistance decreases as temperature rises), allowing the controller to detect evaporator frost load and the end point of a defrost cycle. Fault modes include open-circuit, shorted, or drifted resistance; these cause symptoms such as persistent frost buildup, repeated failed defrost cycles, or abnormal compressor cycling.Technicians verify compatibility by confirming the sensor’s resistance-versus-temperature curve and connector type match the appliance control board, and by measuring resistance at known reference temperatures (such as ice water ~0 °C) before replacing the part to ensure correct calibration and reliable defrost control.
- Common symptoms of a failing sensor: excessive frost,failed defrost termination,long compressor run times,or erroneous temperature readings.
- Functional features: thermistor (NTC) behavior, 5V reference signaling, OEM connector and form factor (yellow).

How the DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM Operates Within the Defrost and Temperature Regulation Circuits
The DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM is a temperature-sensing element used by the refrigerator control board to provide an analog temperature signal. The component is a negative temperature coefficient (NTC) thermistor that forms a voltage divider with an internal pull‑up on the control PCB; the board supplies a 5 V reference and reads the resulting voltage to infer temperature. Its electrical characteristics and connector pinout are matched to Samsung NW2 control modules, so replacing a failed sensor with the OEM part preserves the expected resistance‑to‑temperature curve and signal behavior required by defrost termination logic and cabinet temperature control algorithms.
Within the defrost circuit the sensor monitors evaporator or nearby air temperature so the controller can determine when frost has melted and safely terminate the heater cycle; in temperature regulation it provides continuous feedback used to modulate compressor run time, fan/damper control, and hysteresis thresholds.Faults manifest as stuck defrost cycles, premature or extended cooling, or diagnostic error codes; technicians typically verify operation by measuring resistance at ambient temperatures and by observing the analog voltage change while the unit warms or cools. When replacing, use the OEM DA32-00024V part to ensure compatibility with the control board’s calibration and to avoid mismatched resistance curves that can lead to incorrect defrost timing or temperature control instability.
- Key behaviors: NTC response (resistance falls as temperature rises), analog voltage output proportional to temperature.
- Common symptoms of failure: open circuit, no voltage variation, intermittent readings causing erratic defrost or temperature drift.
- Diagnostic checks: measure resistance at known temperatures and observe the voltage at the connector during operation.

Common Failure Symptoms and diagnostic Signal Patterns for the Temperature Sensor
The DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM is a temperature sensing element used by Samsung refrigerator control boards to monitor evaporator and compartment temperatures and to terminate defrost cycles. Technically, this part behaves like a thermistor-style sensor that presents a predictable change in resistance with temperature and is intended to interface with 5 V measurement or pull-up circuitry on the main PCB.When functioning normally the sensor provides a stable analog signal (resistance or a corresponding voltage) that the controller converts to a temperature value; when replacing or testing this OEM unit, verify connector pinout and supply compatibility to ensure correct interfacing with the refrigerator’s control electronics.
- Open circuit (infinite resistance): controller reads a temperature fault or extreme value and defrost control may fail to start or stop.
- Short circuit (very low resistance): controller sees a constant extreme temperature indicating a sensor failure and may disable heating or cooling cycles.
- Stuck or unchanging resistance/voltage: suggests a failed element or poor thermal contact (sensor not thermally coupled to the evaporator).
- Intermittent or noisy signal: wiring, connector corrosion, or a cracked sensor lead causing erratic temperature readings and irregular defrost timing.
- Slow drift in response: gradual degradation or contamination inside the sensor package causing inaccurate temperature tracking over time.
| Item | Description |
|---|---|
| Signal type | Thermistor-style resistance read by the control board; often converted to a voltage via pull-up resistor on the PCB. |
| Typical diagnostic check | Measure resistance across the sensor while changing temperature (ice/warm air) or measure voltage at connector with engine running; response should be smooth and monotonic. |
For practical diagnostics, measure the sensor both at the harness connector and at the board input to localize faults: a correct resistance change at the sensor but a fixed voltage at the board connector points to a wiring or PCB input problem, whereas abnormal resistance at the sensor indicates the sensor itself is faulty.Use a DMM to record resistance at two known temperatures (ambient and chilled) and examine the curve for smooth change; use an oscilloscope or a high-resolution DMM to detect noise or intermittent drops that produce erratic readings. When replacing the unit, confirm the DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM matches the original connector, supply logic level, and mounting method to preserve thermal coupling and accurate operation.
Replacement Considerations, OEM Compatibility and Step-by-Step Installation Procedures
The DA32-00024V Samsung SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM is a refrigerator evaporator/defrost thermistor that provides the control board with a temperature-dependent resistance signal referenced to a 5 V supply. In operation the part senses coil or airflow temperature to permit accurate defrost termination, fan control, and compressor logic; its response time and placement relative to the evaporator coils determine how closely the measured value matches the actual coil temperature. This OEM sensor uses the factory two‑pin yellow connector and a negative temperature coefficient behavior common to appliance thermistors, so electrical compatibility with the control board (pinout, reference voltage, and resistance curve) is the primary criterion when replacing it with a like-for-like part.
When replacing the sensor, match the OEM part number and connector, inspect the harness and mounting clip for corrosion or mechanical damage, and preserve the original sensor placement to maintain the same thermal coupling. Basic replacement steps include:
- Disconnect power to the appliance before accessing the evaporator compartment.
- Locate the sensor along the evaporator or in the airflow path, note orientation and any adhesive or clip location, and unplug the two‑pin yellow connector.
- Remove the old sensor from its clip or adhesive, then measure resistance with a multimeter to confirm continuity and NTC behavior by warming the bead slightly and observing a decreasing resistance.
- Install the DA32‑00024V in the identical position, secure it with the original clip or thermal adhesive, and fully seat the connector.
- Restore power and use the service menu or a diagnostic meter to confirm the control board reads a plausible temperature; monitor one defrost cycle to ensure proper termination.

Q&A
What is the DA32-00024V (SENSOR TEMP;NW2 5V F DEF SENSOR YELLOW 2 OEM) and what does it do?
This is an OEM temperature sensor (thermistor-style) used in Samsung refrigerators/freezers. It measures evaporator or freezer temperature and sends that information to the main control board so the appliance can control compressor run times, fans and the defrost cycle. The “5V” indicates it is indeed intended for a 5V sensing circuit, and “DEF” suggests it is used in defrost/evaporator monitoring. The yellow color/connector helps identify the lead/plug on the harness.
Which Samsung models use this part and how do I check compatibility?
Compatibility is persistent by the part number (DA32-00024V) and the appliance model. Always confirm by checking the OEM parts list for your refrigerator model or by matching the physical connector,wire length and mounting location.If in doubt, provide your refrigerator model number to a Samsung parts dealer or look up the part in an official parts diagram to verify fitment.
What are common symptoms that indicate this sensor is faulty?
Typical signs include incorrect temperature readings (too warm or too cold),frequent or failed defrost cycles,ice buildup on the evaporator,the compressor running constantly or not running when it should,and error codes related to temperature sensors on the control panel. Intermittent operation or erratic temperature control can also point to a failing sensor.
How can I test the sensor to see if it is working?
First unplug the appliance. Remove the sensor from its mount and use a digital multimeter to measure resistance across its terminals. A working thermistor will show resistance that changes with temperature (for an NTC thermistor, resistance decreases as temperature rises).Check resistance at room temperature, then warm or cool the sensor (e.g.,with warm water or an ice bath) and verify the resistance changes smoothly.If the sensor is open (infinite resistance) or shorted (near 0 Ω) or shows no change with temperature, it is faulty. For live diagnostics, a technician can measure the voltage signal at the control board connector while powered (observe electrical safety and unplug before disconnecting connectors) – consult the appliance wiring diagram or service manual for expected voltage behavior.
Is replacing the DA32-00024V challenging and do I need to recalibrate after replacement?
Replacement is typically straightforward: unplug the refrigerator, remove the interior rear/freezer back panel to access the evaporator area, disconnect the sensor harness, unclip or remove the sensor from its bracket, and install the new sensor in the same position. Connect the harness and reassemble. No special calibration is usually required; onc powered, the control board will use the new sensor readings. Always follow safety precautions (unplug appliance) and take care not to damage the evaporator fins or sensor wiring.
Does the sensor have polarity or a specific wiring orientation I must observe?
Most refrigerator thermistors are passive two-wire devices and are not polarity-sensitive, so either lead can be connected to either terminal. though, some sensors or harnesses can have keyed connectors or additional wires; match the connector orientation and wiring to the original. If the part you have has more than two wires or an electronic module, consult the wiring diagram or part documentation before installation.
Can I use an aftermarket or generic replacement rather of the OEM DA32-00024V?
Aftermarket sensors are available and can work if they match the same resistance/temperature characteristics,connector type and physical mounting. However, using a non-matching thermistor (different resistance curve) can cause improper temperature control or incorrect defrost termination. For reliability and guaranteed fit, OEM parts are recommended, especially if you cannot confirm the electrical characteristics of the replacement.
Any safety or handling tips I should be aware of when replacing this sensor?
always unplug the refrigerator before servicing. Avoid touching sharp sheet metal or evaporator fins; wear gloves if needed. Do not kink or excessively bend the sensor lead. If you must test on live power, be cautious and only do so if qualified – measure at the control board connector rather than at the evaporator whenever possible, and avoid contact with other live terminals. If you suspect refrigerant or sealed-system issues, stop and call a certified technician; this sensor replacement does not involve refrigerant handling but may require removing interior panels near the sealed system.
