tE
Samsung Dryer
Severity: ModerateWhat Does This Error Mean?
The tE error means your Samsung dryer's temperature sensor (thermistor) has a fault. The sensor monitors drum air temperature during the drying cycle. Without it, the dryer can't control heat properly — so it stops.
Affected Models
- DV42H5200EW
- DV48J7770EW
- DV50K8600EV
- Most Samsung electric and gas dryers
Common Causes
- The thermistor has burned out or reached the end of its lifespan
- The wiring connector to the thermistor is loose or corroded
- Lint buildup on the sensor is causing false temperature readings
- The dryer has overheated and the thermistor has been damaged
- A control board fault is misreading the thermistor signal
How to Fix It
-
Unplug the dryer and wait 10 minutes for a full reset.
A temporary temperature spike can trigger tE. A reset often clears it.
-
Clean the lint filter completely — do this before every test run.
A clogged filter raises drum temperature and can overload the thermistor.
-
Check the exhaust vent duct for blockages.
Restricted airflow raises temperatures and stresses the temperature sensor.
-
Run a short cycle on a low-heat setting after the reset.
If tE returns immediately, the thermistor or its wiring is likely faulty.
-
Call a technician to test and replace the thermistor.
It's a quick job — most technicians can replace it within an hour.
When to Call a Professional
Thermistors are inexpensive parts — usually $10–$25. Accessing them requires removing the dryer back panel. A technician will charge $80–$180 for a full thermistor replacement. If the control board is at fault, costs rise to $200–$400.
Frequently Asked Questions
What is the difference between tE and tS on Samsung dryers?
tE means the thermistor has an open circuit or general fault. tS means the thermistor circuit is shorted. Both point to the same sensor but with different failure modes.
Can I replace the thermistor myself?
Yes, if you're comfortable removing the back panel. The thermistor unplugs and re-plugs — no soldering required. Buy the part for your specific model number before starting.
How long does a dryer thermistor last?
Usually 5–10 years under normal use. Frequent overloading and poor vent maintenance shorten its life. Keeping your vent clean is the best way to extend thermistor life.
