LG Dryer Error Code tE2

The tE2 code on an LG dryer signals a thermistor sensor error, specifically that the temperature being reported by the sensor differs significantly from the actual temperature in the dryer. The thermistor is a resistive sensor that changes its resistance value as temperature changes, and the control board monitors that resistance to regulate heat. When the readings fall outside acceptable limits, the dryer stops and displays tE2 to prevent unsafe operation.

You should not continue running the dryer while tE2 is active. The code indicates the control board cannot accurately monitor the internal temperature, which means the dryer may overheat without proper detection. Continuing to operate it under these conditions creates a potential fire risk and could cause further damage to internal components.

Unplugging the dryer for a few minutes may temporarily clear the tE2 code, but if the underlying thermistor or wiring fault still exists, the code will return once the dryer runs again. A reset does not repair a failed sensor or damaged wiring. Performing the resistance test on the thermistor before attempting a reset will give you a clearer picture of whether there is a real hardware fault that needs to be addressed.

A knowledgeable DIYer can often resolve this error by testing the thermistor resistance with a multimeter while the dryer is unplugged and comparing the reading to the temperature-resistance chart. If the thermistor is out of spec, replacing it is a straightforward repair. Wiring harness inspection and connector reseating are also DIY-friendly steps. Control board replacement, if needed, is more involved but still manageable for experienced repair technicians.

If only the thermistor sensor needs replacement, parts typically cost between $10 and $40, making it one of the more affordable dryer repairs. If the wiring harness requires repair or replacement, costs can rise to $50 to $150 depending on the extent of the damage. A control board replacement, if that turns out to be the root cause, generally runs between $100 and $300 or more for parts alone, with additional labor costs if a technician performs the work.
