Samsung Dryer Error Code tC

The tC code means the dryer's cycling thermistor, which is the sensor that monitors drum air temperature, is sending a resistance reading that is either far too low or far too high for the control board to interpret as valid. This indicates a problem with the thermistor itself, its wiring, or the connectors in that circuit. The dryer will not operate normally until the fault is resolved.

It is not advisable to continue running the dryer while the tC code is active. The cycling thermistor is responsible for preventing the dryer from overheating, and if it is not functioning correctly, the dryer cannot regulate temperature properly. Continued use could result in overheating, damage to clothing, or a more serious safety concern. Resolve the fault before resuming normal use.

Repair costs vary depending on the cause. If only the cycling thermistor needs to be replaced, parts and labor typically fall in the range of $75 to $200. If damaged wiring or a failed control board is involved, costs can increase to the range of $150 to $400 or more depending on the part and labor rates in your area. Getting a diagnostic assessment from a qualified technician before ordering parts is recommended.

Some steps are safe for a homeowner to perform, such as cleaning the lint screen and inspecting the exhaust vent for blockages. Checking and reseating wiring connectors is also manageable for a confident DIYer. However, testing component resistance, identifying damaged wiring inside the dryer cabinet, and replacing parts like the thermistor or control board are tasks best suited to a technician. Samsung recommends contacting a customer service center if the code persists after checking for airflow restrictions.

A power reset, such as unplugging the dryer for a few minutes and plugging it back in, may temporarily clear the tC code, but the code will return if the underlying fault is still present. The thermistor circuit needs to be physically inspected and the problem corrected for the error to stay resolved. A reset alone does not repair a failed thermistor or damaged wiring.
