LG Dryer Error Code tE — General Thermistor Error
What this means
The tE error code on LG dryers is the base-level thermistor error code indicating that one or more temperature sensors have failed or are reading outside the expected range. Unlike the specific tE1–tE6 codes that pinpoint which thermistor has failed, the general tE code means the control board cannot determine the specific sensor at fault, or multiple sensors are reading incorrectly simultaneously. This can be caused by a control board communication failure, a wiring harness issue, or simultaneous failure of multiple sensors. The dryer will not heat properly or may not start a cycle to prevent overheating.

Step-by-step fix
4 stepsPower-reset the dryer
Unplug the dryer for 5 minutes, then plug it back in. A transient electrical issue can cause a false tE code. If the code clears and the dryer operates normally through a full cycle, the issue was temporary.
If the tE code returns partway through a cycle, note the time elapsed — this can help a technician determine which sensor is failing.
Check the thermistor wiring harness
Unplug the dryer and remove the top panel. Locate the main wiring harness that connects the thermistors to the control board. Check all connectors for loose, burned, or corroded pins. Reseat each connector firmly.
A loose harness connector can cause intermittent tE errors that come and go with vibration during tumbling.
Test individual thermistors
Using a multimeter set to ohms, test each thermistor individually. At room temperature, most LG dryer thermistors should read approximately 10,000 ohms. An OL (open) or near-zero reading indicates a failed sensor. Test the inlet, outlet, and drum thermistors.
If one specific thermistor is out of spec, the tE code should normally display as tE1, tE2, etc. A general tE with all sensors in spec suggests a control board issue.
Inspect the control board
If all thermistors test within spec and all wiring is secure, the main control board may have a fault in its thermistor input circuits. Visually inspect the board for burned components, cracked solder joints, or swollen capacitors.
Control board replacement should be a last resort after all sensors and wiring have been verified good.
When to call a professional
If a power reset does not resolve the tE code and all individual thermistors test within spec, a technician should diagnose the control board. Do not attempt to replace the control board without professional diagnosis.
