What Does Error tO Mean?
The Samsung Dryer error code tO indicates a malfunction of the thermistor, which is responsible for regulating the dryer’s temperature. This issue can lead to improper heating or erratic temperature readings, causing the dryer to stop mid-cycle due to internal temperature problems. To address this, basic troubleshooting steps include resetting the dryer and ensuring that the lint filter and exhaust vents are clean to prevent airflow issues.
Common Symptoms:
- Error appears on display during or before drying cycle
- Dryer may stop due to internal temperature issue
Possible Causes
- Temperature sensor (thermistor) malfunction or abnormal readings (medium)
How to Fix Error tO
DIY Fix Basic checks for temperature sensor error
- Turn off and unplug the dryer for at least 1 minute, then reconnect to reset the control electronics
- Ensure the lint filter and exhaust vents are clean to prevent airflow restriction and overheating
- Run a short cycle and observe whether error clears after reset
Technician Only Inspect and test thermistor/temperature sensors
- Disconnect power and access the dryer’s internal temperature sensor/thermistor
- Use a multimeter to check the thermistor resistance against manufacturer specifications
- Replace the thermistor or associated harness if readings are out of range or intermittent
- Reassemble and test the dryer to confirm error no longer appears
Parts needed: Thermistor/temperature sensor, Wire harness connectors
- Error persists after resets and basic cleaning
- Multimeter tests indicate thermistor or wiring fault
- Dryer overheats or repeatedly shuts down mid‑cycle despite cleared vents
