LG Dryer TE1 Error: Inlet temperature sensor error
LG dryer error — here’s what you need to know. The tE1 error code on your LG dryer indicates Inlet Thermistor Failure. This is a Medium severity issue. What Does tE1 Mean on an LG Dryer? The tE1 code means the dryer’s control board has detected an open circuit, short circuit, or an out-of-range reading […]

Answer to continue safely
Is it safe to keep using?
No. The dryer will not heat with a tE1 fault active, making it non-functional. Do not attempt to bypass the sensor — it is a safety component.
Can I reset the code?
Yes. Unplug the dryer for 5 minutes to reset the control board. If the thermistor or wiring fault is genuine the code will return immediately — the error only clears permanently once the faulty part is replaced.
When to stop immediately?
Stop if you notice: The dryer produces no heat — do not attempt to force it to run, The code returns immediately after every power cycle reset.
Symptoms You May Notice
Dryer runs but produces no heat
The drum tumbles normally but the heating element or gas burner will not activate because the control board cannot get a valid temperature reading from the inlet sensor.
Dryer stops mid-cycle without completing
The control board halts the cycle partway through when it detects a thermistor fault, leaving clothes damp and the machine idle.
tE1 code on the display with the dryer non-functional
The tE1 error appears at startup or shortly into a cycle and the dryer will not proceed with heating until the sensor fault is resolved.
Inconsistent temperature performance
The dryer runs too hot, too cold, or cycles erratically because the control board receives inaccurate temperature readings from the faulty sensor.
Possible Causes
Failed inlet thermistor
The thermistor component itself has burned out or drifted out of its resistance specification due to age or heat cycling, giving the control board an invalid reading.
DIY PossibleLoose or corroded thermistor wiring connector
The plug-in connector on the thermistor harness has worked loose from vibration or corroded from moisture, causing an intermittent open circuit that reads as a sensor failure.
DIY PossibleFaulty main control board
The thermistor sensor circuit on the main PCB has failed, causing the board to report a tE1 fault even when the thermistor and wiring are in perfect condition.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the dryer
Unplug the dryer for 5 minutes, then plug back in and attempt a new cycle. A transient sensor glitch may clear with a full power reset.
-
2
Inspect the thermistor wiring harness
With the dryer unplugged, remove the back panel and locate the inlet thermistor (near the heating element or burner). Disconnect and firmly reseat the wiring connector, checking for any bent pins or corrosion.
-
3
Test thermistor resistance with a multimeter
Disconnect the thermistor connector and set a multimeter to the 20kΩ range. At room temperature the thermistor should read approximately 10–50kΩ depending on model. An open reading (OL) or near-zero reading indicates a failed thermistor that needs replacement.
When to Call a Professional
Contact a qualified technician if:
- Thermistor tests within spec but tE1 code persists — control board replacement needed
- No prior appliance repair experience working with wiring harnesses and components
- Wiring harness shows melting, heat damage, or rodent chewing that requires rewiring
