Samsung error code tE: The exhaust thermistor (temperature sensor) is reading outside the expected range or is not detected by the control board. The dryer stops to prevent uncontrolled heating.
The exhaust thermistor (temperature sensor) is reading outside the expected range or is not detected by the control board. The dryer stops to prevent uncontrolled heating.
The exhaust thermistor is typically located inside the exhaust duct near the drum exit or on the heater housing. At room temperature (70°F / 21°C), it should read approximately 10,000–15,000 Ω. Read open (infinite) or shorted (near 0 Ω) means replace the sensor.
Tools needed: Multimeter, Screwdriver set
Disconnect power. Locate the thermistor (usually near the heater or on the wash tub). Check the connector for loose pins or corrosion. Reconnect firmly.
Tools needed: Screwdriver set
With power off, disconnect the thermistor connector. Measure its resistance with a multimeter. At room temperature (20°C / 68°F) most NTC thermistors read around 10,000–15,000 Ω. Refer to your model's service sheet for exact values. A reading of 0 Ω (short) or infinite Ω (open) means replace the sensor.
Tools needed: Multimeter
A shorted heater element can pull down the thermistor reading. Disconnect the heater terminals and retest the thermistor in isolation. If the thermistor reads correctly with the heater disconnected, test the heater separately.
Tools needed: Multimeter
Moisture in the sensor connector can mimic a shorted thermistor. Dry the connector with a hair dryer on low heat and reconnect. Run a cycle to see if the error clears.
Tools needed: Hair dryer
If the sensor tests out of specification, replace it with the OEM part for your model. Thermistors are typically inexpensive ($10–$30) and require only a screwdriver to replace.
