WR23X10582 GE Refrigerator Assembly Temp Sensor is a refrigerator temperature sensor assembly commonly used in GE household refrigeration units; it typically comprises a temperature-sensing element (usually an NTC thermistor) housed with mounting hardware and a wiring connector to interface with the appliance control board. As a hardware assembly rather than a single discrete component, it includes the sensor element, a plastic mounting bracket or clip, and an electrical plug or pigtail designed to match the refrigerator’s harness.
The sensor provides continuous temperature feedback to the refrigerator’s control system and directly affects compressor cycling, evaporator fan operation, damper positioning and defrost control logic. Installed in the fresh-food compartment,freezer compartment or in the airflow path near the evaporator,the sensor reports temperature as a resistance or voltage signal to the main control board.The control board uses that signal to regulate cooling setpoints,initiate or inhibit defrost cycles,and coordinate interactions between the thermostat,fans,and compressor to maintain stable internal temperatures.
This article describes the WR23X10582 sensor’s functional role, compatibility with common GE models, typical failure symptoms (for example persistent temperature errors, long run times, excessive frost or no-cool conditions), and practical troubleshooting approaches technicians and owners can use to isolate sensor-related faults. It also covers replacement considerations such as matching connectors and resistance characteristics, correct mounting and orientation, and the safety and diagnostic checks to consider before and after installing a replacement assembly.

Function and Role of the WR23X10582 Temperature Sensing Assembly in Refrigerator Control Systems
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a thermistor-based sensing assembly that provides the refrigerator control board with a resistance-derived temperature signal. Mounted near the evaporator or internal air stream and wired into the main harness, the sensor converts local air temperature into a predictable resistance change (an NTC characteristic: resistance falls as temperature rises). The control board uses that signal for core functions such as compressor on/off decisions, evaporator fan control, and timed or sensor-driven defrost events; as the board interprets temperature by measuring resistance, the sensor must match the expected resistance/temperature curve for stable operation.
Technicians and appliance owners diagnose WR23X10582 GE Refrigerator Assembly Temp Sensor faults by observing system behavior and verifying the sensor’s electrical response.Common failure modes include open circuits, intermittent connections, or a thermistor element that no longer follows a monotonic resistance curve with temperature. Diagnosing typically involves unplugging the harness and reading resistance with a digital multimeter while comparing the change to expected values as the sensor is warmed or cooled; replacing with the correct OEM assembly preserves the calibration built into the control algorithms, whereas a non‑matching sensor can produce persistent temperature errors or incorrect defrost timing.
- Typical symptoms of sensor issues: incorrect temperature display, long run times, short cycling, or failed/unscheduled defrosts.
- Practical test: measure resistance across the sensor connector and confirm consistent change when applying heat (finger or warm air) or cold.
- Replacement guidance: match connector type and resistance/temperature curve; secure proper mounting to sample representative air.

How the WR23X10582 GE Refrigerator Assembly Temp Sensor Works Inside the Appliance
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a small sensing assembly that contains an NTC thermistor mounted in the refrigerator airflow path to monitor air or evaporator temperature. As temperature changes the thermistor’s resistance changes, and the control board reads that change as a voltage or resistance value to make decisions for the compressor, evaporator fan, and defrost timing. The assembly is designed to plug into the factory wiring harness and must match the original resistance curve and connector pinout for correct operation; physically it is typically located in an air duct or adjacent to the evaporator so it senses the air that the control algorithm uses for temperature regulation rather than the cabinet surface temperature.
When the sensor degrades or becomes disconnected the control system can receive incorrect or no temperature data, producing symptoms such as inconsistent cooling, prolonged compressor runtime, or incorrect defrost cycles. Technicians diagnose the part by observing those symptoms, checking harness and connector integrity, and measuring resistance while changing the sensor temperature (for example, comparing readings at room temperature and from crushed ice).A failed sensor will show either no change in resistance with temperature or an open/short circuit; replacing the assembly with a unit that matches the original resistance versus temperature profile restores proper feedback to the control board.
- Behavior: negative temperature coefficient (resistance falls as temperature increases).
- Common symptoms of failure: temperature drift, continuous run, frequent/no defrost, error codes related to temperature sensing.
- Compatibility note: must match the control board’s expected resistance curve and connector pinout.
- Quick diagnostic: verify connector, measure resistance change across temperatures, inspect mounting and air path for obstructions.

Common Failure Symptoms and Diagnostic indicators for the WR23X10582 Temp Sensor assembly
The WR23X10582 GE Refrigerator assembly Temp Sensor is a temperature-sensing thermistor mounted in the fresh-food or evaporator cavity to provide the control board with real-time temperature feedback. It functions as a variable-resistance device (typically an NTC thermistor) whose resistance decreases as temperature rises; the control board reads this resistance as a voltage and adjusts compressor, damper, and defrost actions accordingly. When replacing or diagnosing the sensor, ensure mechanical fit and connector compatibility with the existing wiring harness and verify the resistance-temperature characteristic matches the original specification so the control logic interprets readings correctly.
Common failure modes produce recognizable operational symptoms and measurable diagnostic indicators.Technicians will often see temperature instability, frequent or prolonged compressor cycles, defrost system faults, or fridge/freezer compartments that are consistently too warm or too cold. Use a digital multimeter to check for an open circuit, short, or a resistance value that does not change smoothly with temperature; also inspect the connector and harness for corrosion or intermittent contact, and observe control-board error codes that reference sensor faults. The list below summarizes practical symptoms and checks that rapidly narrow the cause during field diagnosis.
- Erratic temperature readings or rapid swings in compartment temperature.
- Continuous running or short cycling of the compressor despite normal refrigerant pressures.
- Defrost cycle failures or no defrost initiation when expected.
- Multimeter shows open-circuit (OL) or near-zero resistance indicating break or short in sensor.
- Intermittent operation that improves after wiggling the harness-suggests connector/wiring fault rather than the thermistor itself.
| Item | Description |
|---|---|
| Open-circuit (OL) | Broken lead or internal thermistor failure; control reads no sensor and may throw a temp fault. |
| Near-zero resistance | Shorted thermistor or wiring short; control interprets as extreme cold and may inhibit cooling cycles. |
| Resistance not following temperature change | Sensor out of specification; replace with one that matches the original resistance-temperature curve and connector type. |
Replacement Considerations, Compatible Appliance Models, and installation Steps for WR23X10582 GE Refrigerator Assembly Temp Sensor
The WR23X10582 GE Refrigerator Assembly Temp Sensor is a thermistor-based temperature probe used to provide the control board with the refrigerator or freezer compartment temperature reading. The device behaves as an NTC-style resistance sensor (resistance falls as temperature rises) and is packaged with its mounting bracket and connector to match the OEM harness.In normal operation the control board reads small changes in resistance from the sensor to modulate compressor run time and damper/defrost cycles; an out-of-range resistance or an intermittent open/short on the sensor will generate temperature fault codes or erratic cooling behavior. Verify physical connector shape and mounting method against the refrigerator model before replacement, since some GE assemblies share similar sensors but differ in lead length, clip style, or connector pinout.
When replacing the WR23X10582 GE Refrigerator Assembly Temp Sensor, follow safe diagnostic and replacement practices: remove line power, confirm expected resistance with a multimeter at a known temperature, and compare readings to the technical reference values below. Typical installation steps are straightforward but require careful routing of the sensor leads to avoid ice buildup or contact with moving components; reattach the harness connector in the proper orientation and verify the control board registers the sensor during the applianceS diagnostic mode or after a full power cycle. If the appliance still reports temperature errors after replacement, repeat resistance checks at the sensor plug and at the control board to isolate wiring or board faults before replacing additional components.
- Disconnect power to the refrigerator before service.
- Remove shelving and access panels to reach the sensor location (evaporator/fresh-food area as applicable).
- Measure sensor resistance at ambient and compare to reference; replace if open, shorted, or outside expected range.
- Swap the assembly, secure the mounting clip, and route wires clear of defrost heater and fan blades.
- Reassemble panels, restore power, and run a diagnostic or allow several hours for temperature stabilization to confirm correct operation.

Q&A
What is the WR23X10582 refrigerator temperature sensor?
WR23X10582 is a GE OEM temperature sensor assembly (a thermistor) used in many GE/hotpoint refrigerators. It monitors internal air temperature and sends a resistance-based signal to the control board so the control can run the compressor, fans and defrost cycle correctly.
What are common symptoms of a failing WR23X10582 sensor?
Common signs include incorrect or fluctuating temperatures (too warm or too cold), the compressor running constantly or not running at all, uneven cooling between compartments, frequent/unexpected defrost cycles, or an error code related to the temperature sensor on models that display diagnostics.
How do I test the sensor with a multimeter?
Disconnect power to the refrigerator, unplug the sensor connector, and measure the resistance across the two sensor wires with a DMM. The sensor is a thermistor (NTC) so its resistance should change as temperature changes – typically resistance falls as temperature rises. For reference many GE thermistors are about 10 kΩ at 25 °C, but you should check the model-specific service sheet for exact values. If the reading is open (infinite) or a short (near 0 Ω) the sensor is bad.You can also warm or cool the sensor (with warm water or ice) and confirm the resistance changes smoothly.
Where is the WR23X10582 sensor located in the refrigerator?
Location varies by model but it is indeed commonly mounted in an air duct or on the evaporator cover inside the fresh food or freezer compartment,or attached to the back interior wall. Some units position it on a small plastic bracket or clip. Refer to your model’s parts diagram/service manual for the exact location.
Can I replace the WR23X10582 myself and what tools are needed?
Yes – it is a straightforward repair for someone comfortable with basic appliance work. Tools typically required: screwdriver or nut driver to remove interior panels, needle-nose pliers for clips, and possibly a trim tool.Procedure: unplug the fridge, remove shelves/panels to access the sensor, unplug the sensor connector, release the clip and remove the old sensor, install the new sensor in the same position, reconnect the plug and reassemble. Restore power and verify operation. If unsure, hire a qualified technician.
Do I need to calibrate the refrigerator after installing a new sensor?
No manual calibration is normally required. The control board reads the thermistor resistance directly. After replacement, power-cycling the fridge or running a diagnostic mode (if available) can help confirm the new sensor is read correctly and that temperatures stabilize to normal operating values.
Is WR23X10582 compatible with my GE refrigerator model?
Compatibility depends on the specific refrigerator model. The safest method is to enter your full model number into GE’s parts lookup,check the appliance’s parts diagram,or confirm with an authorized parts dealer. Do not rely solely on visual similarity; confirm the OEM part number or approved cross-reference.
How much does the WR23X10582 sensor cost and where should I buy it?
Prices vary but genuine OEM WR23X10582 sensors commonly range roughly from $10 to $40 depending on source.Buy from authorized GE parts dealers, reputable online appliance parts stores, or directly from the manufacturer to ensure you get a genuine part. Avoid dubious “worldwide” sensors that may not meet the correct specifications.
