Samsung Dryer Error Code tE

The tE code means the control board detected an abnormal resistance value from the thermistor, the sensor that monitors drum air temperature. The reading was either too high or too low for the dryer to operate safely. This can be caused by a clogged vent restricting airflow, a failed thermistor, or damaged wiring connecting the sensor to the control board.

No, you should not continue running the dryer with a tE error active. The code means the dryer cannot reliably monitor its own temperature, which removes a key safety control against overheating. Running it in this condition creates a potential fire risk, especially if the underlying cause is a blocked vent that is already trapping heat.

Disconnect power to the dryer, then locate the thermistor, which is usually a small two-wire sensor clipped near the exhaust duct or heating element. Disconnect its wiring harness and place your multimeter probes on the two terminals. At room temperature, a functional thermistor should read approximately 10,000 ohms. A reading of zero or near-infinite ohms confirms a shorted or open thermistor that needs to be replaced. Always verify the exact resistance spec in your model's service manual, as values vary.

Start by cleaning the lint screen and checking the entire exhaust duct for blockages, kinks, or crushing. If airflow is clear, locate the thermistor (typically mounted near the heating element or exhaust duct) and test its resistance with a multimeter. A reading far outside the expected range, roughly 10,000 ohms at room temperature for most models, indicates the thermistor needs replacement. If the thermistor tests good, inspect the wiring harness for damage before considering the control board.

If the fix is simply clearing a clogged vent or lint screen, the cost is nothing beyond your time. A replacement thermistor is an inexpensive part, typically between $10 and $30 depending on the model, and is a manageable DIY repair if you are comfortable disconnecting wiring connectors. A wiring harness repair or control board replacement is more expensive and more complex, and professional service is reasonable to consider for those components.
