WE04X20685 Genuine OEM GE Dryer Thermistor
The WE04X20685 is a genuine GE OEM center outlet thermistor for GE dryers, and also fits select Hotpoint, RCA, and Kenmore models. This thermistor monitors exhaust air temperature and communicates real-time readings to the control board, letting it track how the dryer is operating throughout the cycle.
Importantly, this thermistor is not part of the heating circuit itself, so it's unlikely to be the cause of a dryer that won't heat or produces too much or too little heat. Instead, when this thermistor malfunctions, it typically affects cycle timing or triggers a fault code, since the control board is receiving inaccurate or missing temperature data from this specific sensor location rather than losing its ability to regulate the heating element. A healthy thermistor reads approximately 100K ohms at room temperature. Common failure causes include moisture exposure gradually degrading the electronics over time, or physical stress damaging the thin connecting wires. Before assuming this thermistor is the cause of any symptom, it's worth confirming your exhaust venting has good airflow and is free of obstructions. It directly replaces WE4M336, 4369857, 76J1HX0005, AP5985030, AGE25863, EAP11721518, EAP11721518, OEM17955099, PD00043358, PS11721518.
Quick Answer
The WE04X20685 Genuine OEM GE Dryer Thermistor fixes GE, Hotpoint, RCA, and Kenmore dryers with incorrect cycle timing or a fault code related to this sensor. Reads approximately 100K ohms at room temperature. Replaces WE4M336, 4369857, 76J1HX0005, AP5985030, AGE25863, EAP11721518, EAP11721518, OEM17955099, PD00043358, PS11721518. This thermistor is not part of the heating circuit — it's unlikely to be the cause of a no-heat or overheating problem, but can affect cycle timing or trigger a fault code if defective.
Common Problems This Part Fixes
Incorrect or inconsistent cycle timing
Fault code related to this thermistor or temperature sensing
Erratic cycle behavior not explained by a heating element or thermal fuse issue
Control board receiving inaccurate temperature data from this sensor location

Compatibility
This thermistor is compatible with select GE dryers, and also fits select Hotpoint, RCA, and Kenmore dryers built on the GE platform.
Note: This is a center outlet thermistor and is not in the heating circuit — a different function from some other GE thermistors that do regulate heat output directly. Always verify your full model number before ordering, since GE uses different thermistor designs and resistance ratings across its dryer lineup. Contact our support team with your model number if you're unsure.

Installation Notes
⚠️ Unplug Dryer Before Starting — Check Venting Before Assuming This Sensor Is At Fault Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Before replacing this thermistor, confirm that airflow at the home's outside vent hood is good and that the dryer's venting is free of obstructions, since this thermistor is not part of the heating circuit and won't cause a heating problem on its own. Remove the back panel of the dryer, typically secured with several screws, to access the thermistor's mounting location. Test the old thermistor with a multimeter for electrical continuity to confirm it's actually faulty before replacing it. Photograph the wiring before disconnecting anything. Disconnect the wire terminals from the old thermistor and remove it from its mounting position. Install the new WE04X20685 in the same position, reconnect the wire terminals, and reattach the back panel. Restore power and run a test cycle to confirm normal cycle timing with no fault codes. Tools needed: Phillips or nut driver (model-dependent), multimeter, work gloves.
Frequently Asked Questions
My dryer isn't heating. Is this thermistor the cause?
Unlikely. This is a center outlet thermistor and is specifically not part of the dryer's heating circuit, so a fault here is unlikely to explain a no-heat or overheating symptom. If your dryer isn't heating, check the thermal fuse, heating element, or high-limit thermostat first. This thermistor is more likely to be the cause if you're seeing incorrect cycle timing or a specific fault code instead.
What symptoms does this thermistor actually cause when it fails?
Since this sensor feeds temperature data to the control board without being in the heating circuit itself, a failure here typically shows up as incorrect cycle timing or a fault code related to this specific sensor, rather than affecting how hot or cold the dryer runs.
Should I check anything else before replacing this part?
Yes — confirm your dryer's exhaust venting has good airflow and no obstructions before assuming this thermistor is at fault, since venting issues can cause a range of symptoms that might otherwise be mistaken for a sensor problem. This is a quick check worth doing first.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by GE to factory specifications — guaranteed fit, materials, and performance. It matches the original resistance curve and mounting configuration of the thermistor originally installed in your dryer.
