Samsung Dryer Error Code TC2

TC2 means the dryer's thermistor is reporting a resistance value that is either too low or too high for normal operation. The thermistor is the temperature-sensing component that helps the control board regulate heat inside the drum. Samsung's diagnostic guidance points to a clogged vent or lint screen as the most common cause, followed by a faulty thermistor or wiring issue.

It is not recommended to continue running the dryer while TC2 is active. The error indicates the temperature monitoring system is not functioning correctly, which means the dryer may not be able to regulate heat safely. Running it in this state risks overheating the load or the internal components.

If the fix is simply cleaning a blocked vent, the cost is minimal, typically just the time or a modest fee for a vent cleaning service. Thermistor replacement parts generally range from around $10 to $40 depending on the model, plus labor if a technician is hired. A control board replacement, if needed, can range from $100 to $300 or more for parts alone.

In many cases, yes. Start by thoroughly cleaning the lint screen and inspecting the entire exhaust vent duct for blockages or kinks. If the code clears after improving airflow, no further repair is needed. If the code persists, diagnosing or replacing the thermistor and inspecting the wiring harness are tasks that a confident DIYer with a multimeter can attempt, though a technician may be needed for control board issues.

A power reset, done by unplugging the dryer for a few minutes, may temporarily clear the code, but it will return if the underlying cause is not addressed. Resetting without fixing the vent blockage or faulty thermistor is not a solution. Address the root cause first for the code to stay cleared.
