Electrolux Dryer Error Code Thermistor error

This error means the dryer's control board has detected a fault in the thermistor circuit. The thermistor is the component that monitors temperature inside the dryer, and the board has found that it is either open circuit, short-circuited, or disconnected. The dryer cannot safely regulate heat without a working thermistor, so it stops normal operation until the fault is corrected.

Running the dryer with an active thermistor fault is not recommended. The thermistor provides the temperature data the control board uses to regulate the heating element. Without accurate temperature readings, the dryer could overheat, potentially damaging clothing or creating a fire hazard. The dryer should remain out of service until the fault is diagnosed and repaired.

A reset may temporarily clear the error code from the display, but the fault will return as soon as the control board re-checks the thermistor circuit and detects the same problem. Because the error points to a hardware fault, either in the sensor itself or its wiring, the underlying issue must be repaired before the error will clear permanently.

Yes, this repair is within reach for a knowledgeable DIYer. The primary fix is replacing the thermistor, which typically involves unplugging the dryer, accessing the sensor inside the cabinet, disconnecting the wiring harness, and installing the new part. Before replacing the sensor, it is also worth checking the wiring connector for loose or corroded terminals, as a connection issue can produce the same error without the sensor itself being faulty.

If only the thermistor needs replacement, parts typically range from $15 to $50 depending on the specific model. If a professional technician performs the repair, expect total costs including labor to fall somewhere between $80 and $200. Costs increase if a wiring harness or control board is also involved.
