LG Dryer Error Code tE6

The tE6 code on an LG dryer means the control board has detected an open or short circuit in the compressor outlet thermistor. This thermistor monitors refrigerant temperature as it exits the compressor in the heat pump system. The dryer stops operation when this fault is detected to prevent potential damage. The thermistor must be replaced to resolve the code.

No, you should not continue operating the dryer while tE6 is active. The dryer displays this code and shuts down specifically because the compressor outlet temperature can no longer be monitored reliably. Running the dryer without proper temperature sensing could lead to compressor damage or other system faults. Turn off the dryer and arrange for service.

Repair costs for a tE6 error typically depend on whether only the thermistor needs replacement or if additional components like the wiring harness or control board are also involved. Thermistor parts alone are generally in the range of $20 to $60, while a full service call including labor can bring the total to $100 to $250 or more depending on your location and the extent of the repair. If the control board requires replacement, costs will be higher.

The initial diagnostic step is thermistor replacement, but working on a heat pump dryer involves refrigerant system components and electrical diagnosis that typically require a trained technician. A knowledgeable DIYer can inspect wiring connections and connector terminals, but component replacement in the heat pump circuit is best left to a professional. If you are not confident working around these systems, call for service immediately.

A simple power reset will not permanently clear the tE6 code because the fault is caused by a failed or malfunctioning thermistor, not a temporary software glitch. The code will return as soon as the dryer attempts to operate and the control board reads the abnormal thermistor signal again. The underlying sensor or wiring fault must be corrected before the code will stay cleared.
