Samsung Dryer Error Code tS

The tS code on a Samsung dryer indicates that the thermistor, the component that monitors internal temperature, is reporting a resistance value that is too high or too low. This can be caused by a clogged lint screen, a blocked exhaust vent, or a failed thermistor. The dryer stops operating to prevent potential overheating or damage. Checking airflow first is the recommended starting point before replacing any parts.

It is not recommended to continue using the dryer while the tS error is active. The code indicates that the temperature-monitoring system is compromised, which means the dryer cannot reliably regulate heat. Running the dryer without a functional thermistor could lead to overheating, damage to clothing, or a fire hazard, especially if the underlying cause is a restricted vent system.

A reset may temporarily clear the tS code, but the error will return if the underlying problem has not been resolved. To reset the dryer, unplug it from the power outlet for a few minutes and then restore power. If the code reappears after the reset, the cause, whether a blocked vent, a faulty thermistor, or a wiring issue, needs to be diagnosed and corrected before the dryer will operate normally.

Start by cleaning the lint screen thoroughly and inspecting the exhaust vent hose for kinks, blockages, or crushed sections. If airflow is clear and the error persists, use a multimeter to test the thermistor's resistance and check the wiring connections between the sensor and the control board. If the thermistor reads open, shorted, or fails to change resistance with temperature, it will need to be replaced.

If the issue is simply a clogged lint screen or blocked vent, there may be no parts cost at all, just time spent cleaning. If the thermistor needs replacement, parts typically cost in the range of $10 to $40, with professional labor adding $75 to $150 or more depending on the service provider. A full control board replacement would be the most expensive scenario, potentially running $150 to $350 or higher for parts and labor combined.
