LG Dryer tE1 error code

Difficulty: Hard · Cost: $20–$150 · Duration: 5m

The tE1 error means your LG dryer detected a problem with the thermistor — the sensor that monitors the temperature inside the drum during the drying cycle. Without an accurate temperature reading the dryer cannot control heat safely and stops the cycle. A reset clears it in some cases but if tE1 keeps returning the thermistor or its wiring will need to be inspected and replaced by a technician.

Common causes

  • Thermistor has malfunctioned or failed completely
  • Wiring connection to the thermistor is loose or damaged
  • Temporary electronic glitch causing a false thermistor error

How to fix it

  1. 1

    Unplug the dryer from the outlet or turn off the circuit breaker supplying it

  2. 2

    With the power off hold START/PAUSE for about five seconds

  3. 3

    Restore power and try running a cycle again

  4. 4

    If tE1 returns after the reset the thermistor needs inspection and replacement by a technician
