LG Dryer tE3 error code

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

The tE3 error means your LG dryer detected a problem with the thermistor — the temperature sensor that monitors and helps maintain the desired heat level inside the drum during the drying cycle. Without an accurate temperature reading the dryer cannot control heat safely and stops the cycle. This is similar to tE1 and tE2 but represents a different thermistor fault condition. A reset clears it in some cases but if tE3 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 reading

How to fix it

1

Unplug the dryer from the outlet or turn off the circuit breaker supplying it
2

With the power off press and hold the START/PAUSE button for 5 seconds
3

Restore power and try running a cycle again
4

If tE3 returns after the reset the thermistor needs inspection and replacement by a technician
