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
- Record the full tE suffix and exact model. Stop for overheating, smoke, burning or gas smell, a blocked-exhaust warning, damage or an electrical hazard; do not run a warming or test cycle under those conditions.
- Follow only the matching source branch below and exact model controls. Do not open a sensor, heater, gas or wiring area or bypass a temperature device.
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
- For tE1/tE3, LG directs unplugging or switching off the dedicated breaker, then holding Start/Pause for five seconds while the dryer remains without power. Restore power and try the documented cycle only with safe dry access and no unresolved heat, airflow, gas or electrical warning.
- For tE2 during the documented SteamFresh, Steam Sanitary or Steam Option context, LG separately describes selecting SteamFresh, using More Time until Big/Bulky appears, then Start. Check the exact model instructions and winter vent conditions first; this is not the tE1/tE3 power-reset procedure.
- FaultCodeLab limits the applicable path to one monitored attempt. If the full code returns or a hazard appears, stop and request LG service. Do not add a generic cool-down retry or an unspecified heated test programme.
When to call a technician
- Request LG service if the code persists or recurs after its applicable documented path, the exact suffix/model controls are uncertain, or safe heat/vent/power conditions cannot be established.
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
- The tE1/tE3 sections report a thermistor-related problem without identifying a failed replacement part.
- The separate tE2 section describes cold conditions or improper venting during steam cycles.
FAQ
What does LG Dryer code tE1 usually mean?
LG documents tE1/tE3 as thermistor-related warnings and separates tE2 in cold steam-cycle conditions; preserve the full suffix before choosing a procedure. Model context matters: The existing tE2/tE3 lookup variants retain separate procedure text. tE1/tE3 use an unpowered five-second Start/Pause reset; tE2 has a cold steam-cycle context and different controls. Never choose from the base letters tE alone.
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 LG service if the code persists or recurs after its applicable documented path, the exact suffix/model controls are uncertain, or safe heat/vent/power conditions cannot be established. A qualified technician may check the listed symptoms and source guidance against the model's service information before treating any part as failed.
