LG Styler Error Code tE3 — Duct In Thermistor Error
What this means
The tE3 error code on the LG Styler indicates a failure in the duct inlet thermistor. This sensor monitors the temperature of air entering the Styler's internal duct system. Together with the duct outlet thermistor (tE1), it helps the control board determine the temperature differential across the system for optimal cycle control. A failed duct inlet thermistor means the Styler cannot accurately measure how much heating or cooling the air needs, so it shuts down the cycle for safety.
Alternate codes: TE3
Step-by-step fix
3 stepsPower-reset the Styler
Unplug the Styler for 5 minutes and plug it back in. Start a new cycle to see if tE3 clears. A temporary electrical glitch can cause a false reading.
Clean the lint filter and duct area
Remove and clean the lint filter. Inspect the duct inlet area for lint or debris buildup that could interfere with the thermistor.
A blocked duct can cause the inlet thermistor to read higher-than-normal temperatures.
Contact LG service
If tE3 persists, the duct inlet thermistor needs professional testing and replacement. Contact LG customer support to schedule a repair.
When to call a professional
If the tE3 code returns after a power reset and lint filter cleaning, the duct inlet thermistor requires professional replacement.
