LG Dryer Thermistor Replacement

LG Dryer Thermistor & Temperature Sensor Parts

The thermistor (temperature sensor) in your LG dryer monitors heat levels and tells the control board when to cycle between heating and cooling phases. When the thermistor fails, your dryer either won't heat at all, runs too hot, or shuts off mid-cycle. It's one of the most common LG dryer repairs — and one of the easiest to fix.

Finding the right thermistor starts with your model number. LG uses different sensor types across dryer series, and resistance values must match exactly for proper temperature control. Use our LG dryer thermistor parts page to locate your model and confirm the correct OEM sensor for your machine.

• No heat with motor running: Thermistor failed, blocking heat cycle
• Dryer shuts off early: Sensor reading false high temperature
• Excessive heat, clothes overheating: Thermistor resistance out of spec
• Cycling on/off randomly: Loose or corroded sensor connection
• Error code (dE, tE, or FE): Control board detecting sensor fault

LG Dryer Thermistor & Temperature Sensor FAQs

What does an LG dryer thermistor do?

The thermistor is a temperature-sensitive resistor mounted inside the dryer's blower housing or exhaust vent. As it heats up, its electrical resistance changes, signaling the control board to modulate the heating element on and off. When the thermistor fails, it sends wrong resistance signals — the board either locks out heat entirely or refuses to turn it off, causing overheating or no-heat complaints.

How do I know if my LG dryer thermistor has failed?

A failed thermistor usually shows itself as no heat, excessive heat, or early shut-off. If your dryer motor runs and the blower wheel turns but clothes stay damp and cool, the thermistor is the prime suspect. You can test it with a multimeter — measure resistance at room temperature (should match the OEM spec on your model) and at operating temperature. If resistance is zero, infinite, or way off-spec, replace it.

Do I need to enter my exact LG model number to get the right thermistor?

Yes. LG dryer thermistors vary by series and year — DLE, DLEX, DLHC models use different sensors, and resistance specifications differ. Always enter your full model number to confirm the exact OEM thermistor. Repair Clinic's parts lookup cross-references your model to the correct sensor assembly, avoiding costly returns.

Can I install an LG dryer thermistor myself?

Yes. Most LG dryer thermistors take 10 to 15 minutes to replace. You'll remove the back or front panel, disconnect the sensor wire from the control board, unbolt the old thermistor from its mounting location, and install the new OEM sensor. No special tools required — just follow your model's parts diagram or a service video for exact placement.

LG Dryer Model Number: Where to Look

On LG dryers, look for the model number label inside the door opening, along the cabinet's back panel, or near the control panel. Open the door and check the frame first, then inspect the rear of the appliance if the label is not there. Record the complete model number, including any letters and numbers, since LG uses different parts across dryer series and production years. Type it into our model number lookup and the catalog narrows to parts made for your unit. This filters the full LG dryer parts selection, not just thermistors, to parts matched to your exact model. You order with confidence knowing the fit is right.
