LG Dryer Error Code Et

The Et code on an LG dryer signals a problem with the heater thermistor, the sensor that monitors temperature near the heating element or gas burner. The control board is not receiving a valid reading from this sensor, so it stops the heating function as a precaution. On gas models, an interrupted gas supply can also trigger this code. The dryer will typically not heat until the fault is corrected.

Yes, this code relates to the dryer's temperature monitoring system, which is a critical safety circuit. The dryer disables heating when Et appears to prevent uncontrolled heat buildup. You should avoid bypassing or ignoring this fault and diagnose the root cause before resuming normal operation.

A reset may temporarily clear the Et code, but it will return if the underlying fault has not been corrected. Unplugging the dryer for a few minutes and restarting it is worth trying to rule out a transient signal issue. However, if the thermistor is failed, the wiring is damaged, or gas supply is inconsistent, the code will reappear once the dryer attempts to heat again. Proper diagnosis and repair are required for a permanent fix.

Some causes of the Et code are DIY-friendly, such as reseating a loose wiring connector at the thermistor. Replacing the thermistor itself is also a straightforward repair for someone comfortable working inside the dryer cabinet. Gas supply checks on gas dryers can be done by confirming the shutoff valve is fully open, but any work involving gas lines or valves should be handled by a qualified technician.

Repair costs depend on the cause. A replacement heater thermistor is generally an affordable part, typically in the range of $10 to $40. If the control board or gas valve needs replacement, costs will be higher, potentially ranging from $100 to $300 or more for parts alone. Adding labor for a professional repair will increase the total cost.
