Thermistor error — air temperature sensor out of range

The control board reads an implausible value from the air thermistor (tE1 = the exhaust/air sensor circuit; tE2 variants point at the inlet sensor on some models). Without a believable temperature signal the dryer won't heat. The sensor is cheap and the test takes five minutes with a multimeter.

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Clean around the sensor

    Unplug the dryer, remove the lower front or back panel, and vacuum lint from the thermistor on the blower/heater housing.

  2. 2

    Test the thermistor

    Measure resistance at room temperature — roughly 10kΩ on LG dryers. Open or near-zero readings confirm replacement.

  3. 3

    Replace the sensor
