What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Stop the cycle and let the dryer cool.
- Clean the lint filter and check visible airflow restrictions.
- Review the model manual before any internal inspection.
- Let the appliance cool before any retry; if the code appears cold, the sensor warning is still active.
- Check for unusual heat or odor from outside the appliance; if present, stop use and keep power off.
- Try one normal restart only after cooling; if the code returns, avoid repeated heating cycles.
Applicability
Regional guidance · LG dryers that display tE temperature-sensor codes · United States
LG groups several tE displays as thermistor-related but gives different context for tE2 in cold steam-cycle conditions; preserve the full displayed suffix and confirm the model guide.
Reset or retry steps
- LG points users to a simple power reset path for tE1 and tE3.
- If tE2 appears during a steam cycle, follow LG's model-specific steam-cycle guidance before retrying.
When to call a technician
- Request service if a thermistor code returns after reset.
- Call service if the dryer overheats, shuts down repeatedly, or has damaged wiring.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Do not keep running a dryer that overheats, smells hot, or has a severe airflow restriction warning.
A restricted vent can increase dryer fire risk; stop if there is burning smell, smoke, or repeated overheating. Persistent headaches, dizziness, nausea, or weakness near a gas appliance can be a carbon monoxide warning: leave the area, ventilate only if safe, and call emergency services or qualified service for a CO check.
- Safe next step
- Stop the cycle, let the dryer cool, clean the lint screen, and check only visible vent restrictions before retrying.
- Stop when
- Airflow stays weak, the dryer overheats, the outside vent cannot open, or gas/electrical supply concerns appear.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Thermistor or temperature sensor reading outside the expected range
- Cold-condition behavior on steam cycles for tE2
- Restricted airflow contributing to abnormal temperature behavior
FAQ
What does LG Dryer code tE1 usually mean?
Commonly logged when the dryer detected a thermistor or temperature-sensing issue. Model context matters: LG separates tE2 as a thermistor-related cold-condition behavior that can appear during some steam cycles.
Can I keep using the dryer with code tE1?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Do not bypass temperature sensors.
When should I call a technician for LG tE1?
Request service if a thermistor code returns after reset. A qualified technician may check Thermistor, Temperature sensor, and Wiring harness against the model's service information before treating any part as failed.
