What tE1 (Duct Out Thermistor Error) Means
tE1 indicates a Duct Out Thermistor Error, per LG's Styler Help Library error-code list - a fault with the temperature sensor at the duct outlet of the Styler's internal air/steam system.
Common Causes of tE1 (Duct Out Thermistor Error)
- Duct-out thermistor has failed or lost contact
- Sensor wiring fault
🔧 One Safe Check You Can Try
The unit will require a repair service; LG's Styler error-code list doesn't give an owner-level reset step for this fault the way some of its washer and dryer codes do, so contact LG's 24/7 Chat Support or request a repair rather than opening the cabinet yourself.
⚠ Why You Shouldn't Go Further Than That
- The Styler's duct and thermistor assembly is inside the cabinet's air-handling system, not a surface-accessible part, and LG's own documentation goes straight to recommending service.
- Continuing to run steam or refresh cycles with a faulted duct-temperature sensor means the unit can't confirm it's managing internal air temperature safely for the fabrics inside.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
