WR23X10582 GE Refrigerator Assembly Temp Sensor is a thermistor-based temperature sensor assembly used in GE refrigerators to monitor compartment or evaporator temperatures. The assembly typically combines a temperature-sensing element (commonly an NTC thermistor) with a mounting bracket and connector designed to interface with the appliance wiring harness; its packaged form factor allows straightforward installation and electrical connection to the refrigerator control system.
Inside the appliance, the sensor provides real-time temperature feedback to the main control board, which uses that input to regulate compressor duty cycle, evaporator fan operation, defrost sequencingand any damper or zone-control actuators. Accurate and timely readings from the sensor enable the controller to maintain target setpoints, initiate defrost eventsand prevent inappropriate run states; conversely, a degraded sensor can produce incorrect resistance/voltage signals that lead to overcooling, undercooling, short cycling, or failed defrost operation.
This article will describe the WR23X10582 sensorS expected function and electrical characteristics, identify common failure symptoms and how they present in refrigerator behavior, outline diagnostic tests a technician can perform (including resistance-versus-temperature checks and connector/wiring inspections), and discuss compatibility and replacement considerations such as connector type, mounting orientationand calibration implications for the control board. Practical troubleshooting and service precautions will be presented to help technicians, engineers, and appliance owners evaluate whether the sensor is the root cause of a temperature control problem and how to replace or verify it safely within the appliance system.

Function and Role of the Thermistor in Refrigerator Temperature Regulation
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a thermistor-based temperature-sensing assembly used by the refrigerator control board to monitor compartment or evaporator temperatures. the thermistor is an NTC device whose resistance decreases as temperature increases; the control board measures that resistance and converts it to temperature using a calibrated resistance-temperature curve. Because the assembly includes the sensing element, its mounting hardwareand the OEM electrical connector, physical placement and thermal coupling to the air stream or evaporator surface determine response time and the accuracy of the control loop that governs compressor cycling, fan operation, and defrost timing.
- Common symptoms of sensor faults: incorrect temperature readings, persistent warm compartments, short-cycling, or continuous compressor operation.
- Basic diagnostic steps: visually inspect the harness and mounting, measure resistance at known temperatures (room and ice-water)and verify NTC behavior (higher resistance at lower temperature).
- Compatibility considerations: replace with the correct assembly to preserve connector pinout and resistance curve; mismatched thermistor characteristics can produce control errors even if the connector fits.
Technicians should diagnose the sensor electrically and mechanically: an open-circuit or infinite resistance reading indicates a failed sensor or connector break, while a shorted sensor shows very low resistance and will register as an abnormally high temperature to the controller. For practical testing, record resistance at ambient (≈25 °C) and at 0 °C (ice water) and compare the delta and absolute values to the expected NTC behavior for the refrigerator family; large deviations or non-monotonic readings require replacement of the assembly. When ordering a replacement, match the WR23X10582 part number or the OEM cross-reference to ensure the same resistance curve, mounting interface, and connector so the control algorithm remains properly calibrated.

How the WR23X10582 GE Refrigerator Assembly Temp sensor Works Inside the Appliance
WR23X10582 GE Refrigerator Assembly Temp Sensor is an NTC thermistor assembly that supplies the refrigerator control board with a precise resistance-based temperature signal from the evaporator or cabinet area. The control board converts that resistance into a temperature reading to regulate compressor runtime, evaporator fan operationand defrost termination. Inside the appliance the sensor is mounted where it senses air or surface temperature and is read periodically; consistent, predictable resistance change is required for closed-loop temperature control and for the defrost algorithm to end when ice has melted.
The sensor behaves like most thermistors: its resistance decreases as temperature risesand it is tolerant of the refrigerated environment when properly sealed and mounted. Technicians diagnose the part by checking for a stable resistance that changes with applied heat or cold, by verifying proper connector seatingand by confirming the control board receives the expected voltage drop across the sensor. Using a non‑matching thermistor with a different resistance curve can shift control thresholds and produce incorrect cycling or defrost behavior, so replacement with the correct assembly or an equivalent with the same characteristic curve is recommended.
- typical features: NTC thermistor element, sealed housing, two‑pin harness connection, designed for evaporator or cabinet mounting.
- Common symptoms of failure: persistent temperature drift, continuous compressor run, rapid frost buildupor control board fault codes indicating an open/short sensor.
- Diagnostic tip: measure resistance while warming or cooling the sensor; a monotonic change in resistance confirms the element is responding.

common failure Symptoms and Diagnostic Signal Patterns for the WR23X10582 Sensor
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a temperature-sensing assembly used by the refrigerator control to report air or evaporator temperatures for compressor cycling and defrost management. The assembly typically contains a thermistor (negative temperature coefficient) mounted in a housing with the proper connector and harness for direct-fit compatibility with specified GE cabinet and evaporator locations. In normal operation the sensor’s resistance falls as temperature rises; the control board monitors that resistance (or the corresponding voltage) as a feedback signal to trigger defrost, fanand compressor actions. Technicians should treat this part as both a sensor and a connector assembly when evaluating fit and electrical continuity during replacement or compatibility checks.
- Intermittent or no cooling while compressor runs continuously
- Erratic temperature readings on the display or incorrect defrost cycles
- Unusually long or short defrost periods, frost build-upor warm spots
- Multimeter shows open circuit or near-zero resistance at the sensor connector
| Item | Description |
|---|---|
| Resistance behavior | NTC-type: resistance decreases with rising temperature; use out-of-circuit measurement for accurate comparison |
| Failure indicators | Open/infinite or very high resistance indicates a broken sensor/wiring; near-zero indicates a shorted thermistor or harness fault |
To diagnose signal patterns, measure the sensor at the harness: a stable, temperature-correlated resistance curve indicates a functioning sensor, while abrupt jumps or an open/short signature indicates failure. In-circuit voltage at the control connector may be a steady DC value that varies with temperature or a scanned/pulsed waveform produced by the board; compare observed voltages to the service manual or known-good reference. For practical troubleshooting, remove the sensor from the circuit when possible and use a multimeter to verify that resistance changes smoothly as the sensor is warmed or cooled; if the resistance dose not change predictably or the wiring shows intermittent continuity, replace the WR23X10582 GE Refrigerator Assembly Temp Sensor and recheck system behavior.
Replacement Considerations, Step-by-Step Installation Procedureand Safety Precautions
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a thermistor-based sensing assembly used by GE control modules to monitor refrigerator air or evaporator temperatures. the sensor behaves as a negative temperature coefficient device: its resistance decreases predictably as temperature rises and the control board interprets that change to regulate compressor runtime, evaporator fan speed, and defrost timing. For practical troubleshooting, technicians should confirm that the sensor is mechanically positioned in the correct air stream or mounting boss and that the harness and connector match the replacement part; mismatches in probe length, clip positionor connector orientation can produce erroneous readings even when the thermistor element is functional.
Before replacing the sensor, take measures to prevent personal injury and system damage-disconnect power at the breaker or unplug the appliance and allow any nearby panels to cool. Typical installation steps are straightforward: remove the access cover, document sensor orientation and routing, disconnect the harness, swap the sensor assembly without flexing or kinking the probe, secure the new assembly in the same locationand restore power to verify the refrigerator completes a normal temperature-sensing cycle. Monitor control-board diagnostics or measure the sensor’s electrical response while applying a controlled temperature change to confirm correct operation after installation.
- Turn off power and remove access panels.
- Note orientation and mounting clips before disconnecting the sensor harness.
- Replace with a mechanically and electrically compatible assembly, route and secure wiring as original.
- Restore power and verify sensor response via diagnostics or controlled temperature test.

Q&A
What is the WR23X10582 temperature sensor and how does it work?
The WR23X10582 is an OEM temperature sensor assembly (thermistor type) used on many GE refrigerators. It measures compartment air temperature and sends a resistance-based signal to the refrigerator control board.As the temperature rises the thermistor resistance decreases (negative temperature coefficient), and the control board uses that change to regulate compressor, fans and damper operation.
What common symptoms indicate the WR23X10582 sensor is failing?
Typical signs include the refrigerator or freezer running too cold or too warm, frequent defrost cycles, continuous compressor run, temperature alarmsor inconsistent temperatures between cycles.The control board may also display error codes related to the temperature sensor in diagnostic mode.
Where is the WR23X10582 sensor located on the refrigerator?
Location varies by model, but the sensor is usually mounted inside the fresh-food section or in an air duct between the freezer and fresh-food compartments, frequently enough behind a plastic cover or evaporator housing. Consult your model’s service manual or parts diagram to find the exact location before disassembly.
How do I test the WR23X10582 sensor with a multimeter?
Unplug the refrigerator and disconnect the sensor from the harness. Set a digital multimeter to measure resistance (ohms). Measure the sensor leads-you should see a stable resistance value that changes if you warm or cool the sensor (e.g., hold it in your hand or place it briefly in ice water).The resistance should decrease as temperature increases. For exact resistance-to-temperature values, refer to the refrigerator’s service manual; if the value is open, shorted, or does not change with temperature, the sensor is likely bad.
Can I replace the sensor myself and how do I do it safely?
Yes,most handy owners or technicians can replace it. Safety steps: unplug the refrigerator before starting. Remove the interior panel or duct to access the sensor, unplug the sensor connector from the harness, remove any clips or screws, and install the new sensor in the same orientation. Reconnect the harness, reassemble the panels, then plug the fridge back in. If unsure, consult a technician or the service manual.
Does the sensor need calibration or programming after replacement?
Normally no-the sensor is a passive thermistor and the control board reads it directly, so replacement is typically plug-and-play. Occasionally you may need to reset the control board or run the refrigerator’s diagnostic/initialization sequence per the service manual to clear errors; but no special calibration is required for the sensor itself.
How do I know if the replacement part is compatible with my GE fridge?
Match the part number (WR23X10582) to the OEM parts list for your refrigerator model. Check the model number on the refrigerator’s inside wall and verify compatibility on the parts supplier or GE service site.Avoid assuming fit; some sensors look similar but use different resistance curves or connectors.
Are there any other checks I should do if replacing the sensor doesn’t fix the temperature problem?
yes. Verify proper airflow through ducts and vents, check the evaporator for frost/ice buildup (possible defrost failure), confirm evaporator fan and condenser fan operation, inspect the damper and door seals, and check compressor and start components. If the control board is faulty it may misread an otherwise good sensor-run the refrigerator’s diagnostic mode if available to confirm sensor readings before replacing additional parts.
