Samsung Washer Error Code HE2

HE2 means the dryer heater center's red overheat temperature sensor has detected a temperature above 145°C and has activated to shut down the heating circuit. This is a safety fault designed to prevent damage or fire. The sensor includes a small reset button that can clear the fault if the overheat was a temporary event. If the code returns after resetting, the sensor or another component in the heating system needs further inspection.

No, you should stop using the dryer function until the cause of the overheating is identified and corrected. The HE2 code indicates that temperatures exceeded 145°C, which is beyond the normal operating range and represents a potential fire risk. Running the unit repeatedly by resetting the sensor without addressing the root cause can damage internal components and increase safety risks.

Repair costs vary depending on the root cause. Replacing the overheat temperature sensor is generally the least expensive fix, typically ranging from around $20 to $80 for the part, with labor costs added if a technician is involved. Replacing a heating element or thermostat can bring the total repair cost to anywhere from $80 to $250 or more depending on parts and labor rates in your area. A control board replacement, if required, is typically the most expensive scenario.

Start by pressing the center button on the red temperature sensor lightly to reset it. Before restarting the unit, check the exhaust duct and lint filter for blockages, and make sure the vent hose is not kinked or crushed. If the code comes back after clearing the obstruction and resetting, the sensor itself may have degraded and should be replaced. Persistent HE2 faults that return even with a new sensor point to a failed thermostat or heating element.

Resetting the sensor by pressing the center button will clear the fault temporarily, but it will not fix the underlying cause. If the overheating was triggered by a blocked vent or filter, cleaning that obstruction before resetting may resolve the issue long-term. If the code returns without an obvious airflow restriction, the temperature sensor, cycling thermostat, or heating element likely needs to be replaced.
