Error codetE1 / tE3
ApplianceDryer
Both tE1 and tE3 mean the dryer has found a problem with its thermistor, the sensor that reads temperature. LG treats the two as one family with one reset, described as a simple factory reset.
How to do the reset
Cut power to the dryer by unplugging it or tripping its circuit breaker.
With the power still off, press and hold START/PAUSE for 5 seconds.
Bring power back and run a cycle to see whether the code is gone.
A repeat of the code after the reset can mean the dryer requires repair.
Other thermistor and power codes
tE2 is a thermistor error seen in cold conditions or steam cycles.
tE4 is a thermistor fault that has no owner reset.
If the reset does not hold, call (415) 223-7887 from San Francisco or the surrounding area and ask for LG dryer repair. State which tE code appeared, and that you held START/PAUSE with the power off.
Model compatibility: LG reuses codes across series and model years, so tE1 / tE3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
tE1 and tE3 indicate a thermistor (temperature sensor) problem and are cleared with the same reset.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
