What Does Error 1TC Mean?
The Samsung dryer error code 1TC indicates a malfunction in the thermistor, a vital component responsible for regulating temperature. This issue can lead to your dryer stopping mid-cycle or failing to heat properly, causing temperature regulation anomalies during drying. If the thermistor is faulty or there are airflow issues, your dryer may overheat or not heat at all. Regular maintenance and inspection of the thermistor and dryer vents can help prevent this error.
Common Symptoms:
