Samsung Dryer Error Code tC — What It Means & How to Fix It

What Does This Error Mean?

Samsung dryer error tC means the temperature sensor (thermistor) inside the dryer is not reading correctly. The dryer cannot control heat properly without an accurate temperature reading, so it stops to prevent overheating. This is often caused by a faulty thermistor or a loose wire connection to the sensor.

Affected Models

Samsung DVE45T6000W
Samsung DVG45T6000W
Samsung DVE50R5400W
Samsung DVE45R6100C
Samsung DVE52M7750W

Common Causes

The thermistor (temperature sensor) inside the dryer drum housing has failed and is sending incorrect readings
The wire harness connecting the thermistor to the control board has come loose or corroded
Lint buildup around the thermistor is insulating it, causing false high-temperature readings
The dryer has overheated in a previous cycle, damaging the thermistor permanently
The main control board has developed a fault and is misinterpreting the thermistor signal

How to Fix It

Unplug the dryer from the wall and wait 60 seconds. Plug it back in and try starting a cycle. A power reset can sometimes clear a temporary sensor glitch.

If the error clears and the dryer runs without issue, monitor it over the next few cycles.
Clean the lint filter thoroughly. A heavily clogged filter causes poor airflow and heat buildup, which stresses the thermistor and can trigger tC.

Clean the lint filter before every single dryer load — it takes about five seconds and prevents many error codes.
Check the exterior vent outlet on the outside of your home. Make sure it is not blocked by lint, debris, or a stuck flap. Restricted airflow causes heat to build up and can damage the thermistor.

A fully blocked exterior vent will eventually damage the thermistor permanently — airflow maintenance prevents costly repairs.
If the error persists, the thermistor likely needs to be tested or replaced. Unplug the dryer, remove the back panel, and locate the thermistor near the heating element or exhaust duct. Check that its wire connectors are seated firmly.

The thermistor is a small oval component with two wires. It is typically held in place by one screw.
A technician can test the thermistor with a multimeter. A working thermistor reads approximately 10,000 ohms at room temperature. If the reading is wildly off, the thermistor needs replacing.

Thermistors for Samsung dryers typically cost between $10 and $25. Labour for a technician visit is usually the larger cost.

When to Call a Professional

Replacing a thermistor requires accessing the inside of the dryer cabinet. If you are not comfortable opening appliances, call a Samsung-certified technician. A thermistor is an inexpensive part but requires correct installation to ensure the dryer heats safely.

Frequently Asked Questions

Is tC the same as tE on a Samsung dryer?

They are related but not identical. tE is a general temperature sensor error, while tC specifically indicates the sensor circuit is out of the expected range. Both errors point to the thermistor or its wiring as the likely cause.

Can I still use the dryer when tC is showing?

No. Do not run the dryer with tC active. Without a working temperature sensor, the dryer cannot regulate heat safely and risks overheating, which is a fire hazard.

How much does it cost to fix error tC?

If the fix is a thermistor replacement, the part itself costs around $10–$25. A technician visit typically adds $80–$150 in labour costs. If the control board is the cause, that part can cost $150–$300 plus labour.
