Washing Machine Sensor & Thermistor Parts

Washing Machine Temperature Sensor and Thermistor Parts

A washing machine thermistor (temperature sensor) tells your washer's control board what the water temperature actually is — so it can adjust fill cycles, heating, and rinse temperatures accordingly. When the thermistor fails, you'll see incorrect wash temperatures, water that won't heat, or cycles that run longer than normal while the machine tries to reach the right temp.

The thermistor is a small part with a big job: it measures water temperature in real-time and sends that data to the main control board. If your, or washer is running long cycles, not heating properly, or showing temperature-related error codes, the thermistor is worth checking. We carry OEM thermistors for all major brands — exact replacements that restore proper temperature control without guesswork.

• Water won't heat: thermistor failure prevents heating element activation
• Cycles run too long: control board can't confirm target temperature is reached
• Temperature error codes and other major brands and other smart washers flag bad sensor readings
• Cold water in warm wash: sensor fails, heating never engages
• Inconsistent water temperature: thermistor reading drifts, cycle repeats heating

Washing Machine Thermistor & Sensor FAQs

How do I know if my washer thermistor has failed?

A bad thermistor usually shows up as temperature-related problems: wash water that stays cold, heating cycles that run indefinitely, or error codes related to temperature (like 's UE or tE codes, or 's error messages). You might also notice the control board trying to heat repeatedly in a single cycle. If you're seeing these symptoms, the thermistor is a prime suspect — it's one of the least expensive washer sensor fixes and usually the right call.

Does the thermistor need to match my exact washer model?

Yes. Even though thermistors look similar across brands, resistance values and connector types vary. Always use your washer's model number to find the correct OEM thermistor. A close-but-wrong thermistor will give false temperature readings and create the same problems you're trying to fix. Repair Clinic's model lookup finds the exact thermistor for your machine.

Can I clean a thermistor instead of replacing it?

Not really. Thermistors are solid-state sensors with no moving parts to clean. If it's reading incorrectly, the internal resistance has changed — cleaning won't fix that. Replacement is the solution. However, before you order, confirm the problem isn't a kinked fill hose, blocked inlet valve, or failed heating element by checking those first.

What's the difference between a thermistor and a temperature sensor?

In most modern washers, thermistor and temperature sensor are the same part — a resistive element that changes resistance based on water temperature, sending that signal to the control board. Older washers sometimes used mechanical thermostats (bimetallic strips), but OEM washers sold today use electronic thermistors. Your model number determines which you need.

Filter Washing Machine Parts by Your Model Number

On many washing machines, the model number is printed on a label along the top edge of the tub opening. Check inside the door frame or lid, and look at the back panel if you do not see it there. The label may also list a serial number, so copy the model number exactly, including letters, numbers, and any dashes or slashes. Type it into our model number lookup and the catalog narrows to parts made for your unit. This filters the full washing machine parts selection, not just sensors or thermistors, to parts matched to your specific model. You get parts that fit the first time.
