LG Dryer Error Code
The drum temperature sensor is faulty. Found on LG steam dryers (TurboSteam series), this sensor ensures steam does not overheat the drum. Requires sensor replacement.
Note the exact error code and any symptoms (sounds, smells, leaks)
Try power cycling the appliance (unplug for 60 seconds)

The drum temperature sensor is faulty. Found on LG steam dryers (TurboSteam series), this sensor ensures steam does not overheat the drum. Requires sensor replacement.
When your LG Dryer displays the tE3 code, it means the appliance's self-diagnostic system has detected a fault that requires attention. LG's smart diagnosis system is designed to surface this error only when the condition is confirmed — meaning a single power cycle that clears the code is not a reliable fix if the underlying cause has not been addressed.
Based on our technicians' experience servicing LG Dryers, the tE3 code is most frequently triggered by the following:
Before scheduling a service call, work through the following steps in order. These checks resolve the tE3 error in a meaningful percentage of cases when the cause is a minor blockage or transient fault rather than a failed component.
If the tE3 code returns after completing the steps above, a component has likely failed and the repair requires disassembly, professional diagnosis, and genuine LG OEM parts. Continuing to run the appliance with an active fault may cause secondary damage — for example, a failing drain pump that is not replaced can overheat and damage the motor or control board.
LG Appliance Experts technicians carry the most common replacement parts for LG Dryers on every service vehicle. In most cases, we can diagnose and complete the repair in a single visit.
Repair costs for the tE3 error vary depending on which component has failed. Typical ranges based on our service history:

Answers to the most common questions our customers ask.
A blown thermal fuse is the #1 cause in LG electric dryers — it trips when the exhaust duct is restricted. Gas LG dryers most often fail due to a faulty igniter or gas valve coils. Both are repairable with genuine LG OEM parts on the first visit.
These codes indicate the exhaust duct is 80%, 90%, or 95% blocked respectively — a safety feature unique to LG Flow Sense technology. Clean the lint filter, inspect the full duct run for kinks or lint buildup, and check the exterior vent flap. This code prevents dryer fires.
Slow drying almost always means restricted airflow — either a clogged lint filter, a kinked or overly long exhaust duct, or a partial heating element failure. Clean the duct from wall to exterior. If the issue persists after cleaning, a technician should test the heating element output.
Squeaking in LG dryers is typically worn drum glides (front slides) or a failing drum support roller. The drum belt may also be fraying. These are inexpensive repairs when caught early but can progress to drum damage if ignored.
TurboSteam uses a water reservoir and steam generator to refresh clothes. Common issues include a clogged steam nozzle, a failed steam generator element, or a faulty water inlet valve. Yes — all TurboSteam components are repairable with genuine LG OEM parts.
