Observation-led diagnosis
Start with what you can actually see
An error code identifies a system, not a replacement part. Match the observable condition before deciding what to check next.
| What you observe | What it suggests | Safest next move |
|---|---|---|
| tE1 appeared once and the dryer has cooled normally | The sensor reading or control may have been interrupted temporarily | Owner checkUse LG’s power-off and five-second START/PAUSE reset once, then observe one cycle. |
| The code returns after the single reset | The thermistor, its wiring, or the control needs diagnosis | Stop and serviceStop using the dryer and request repair rather than repeating the reset. |
| The dryer becomes unexpectedly hot or smells hot | Temperature monitoring or airflow may not be reliable | Stop and serviceEnd the cycle, disconnect power if safe, and arrange prompt inspection. |
| The breaker trips when power is restored | An electrical fault may be present in the appliance or supply | Stop and serviceLeave the breaker off and use a qualified technician or electrician. |
Safe diagnostic path
What to check, in order
- 01
Stop the dryer and let it cool.
- 02
Unplug the dryer or switch off its correctly identified circuit breaker.
- 03
With power still disconnected, hold START/PAUSE for five seconds as LG directs.
- 04
Restore power and try one controlled cycle.
- 05
If tE1 returns, stop using the dryer and arrange LG repair.
Know when to stop
Don’t push past this point
Do not continue if tE1 returns, temperatures are abnormal, the dryer smells hot, or the circuit breaker trips.
- Do not measure or replace the thermistor while the dryer is energized.
- Do not bypass a temperature sensor or thermal safety device.
- Do not keep resetting a dryer that cannot regulate temperature predictably.
