Samsung Dryer Error Code tE: How to Fix It

The Logic Verdict

It’s usually lint. A “Thermistor Error” sounds scary, but it often just means the sensor is coated in lint or the vent is clogged, causing weird temperature readings. Clean everything first.

What It Means

The tE code (or tE1, tE2, tE3) stands for Thermistor Error. The dryer’s temperature sensor (thermistor) is sending resistance values that are out of range (too hot or too cold).

Common Causes

1. Clogged Lint Screen/Vent: Restricts airflow, causing heat spikes.
2. Dirty Moisture Sensors: Lint buildup on the metal bars inside the drum.
3. Faulty Thermistor: The sensor itself has failed (common on older units).
4. Loose Wiring: Vibration has loosened the wire harness.

Step-by-Step Fix

1. Deep Clean: Wash the lint screen with soap and water (fabric softener leaves an invisible film). Vacuum the slot where the filter goes.
2. Check the Vent: Go outside and ensure the exhaust vent is blowing strong air. If not, clean the duct.
3. Power Cycle: Unplug the dryer for 60 seconds.
4. Test: Run a cycle on “Time Dry” (which bypasses moisture sensors). If it works, the issue is likely the moisture sensor bars needing a scrub with vinegar.
5. Replace Thermistor: If the code returns immediately upon power-up, the thermistor component needs swapping.
