What Does Error CT Mean?
The Samsung dryer error CT indicates a malfunction related to the drum temperature sensor. This error occurs when the internal temperature is either too cold (below freezing) or too hot, preventing the dryer from starting or causing it to stop unexpectedly. Symptoms include the CT error code appearing on the display, the dryer being cold to the touch, or unusually warm during operation. Ensuring the dryer is in a suitable environment and checking for proper ventilation can help resolve the issue.
Common Symptoms:
- Error code CT appears on display during or before a drying cycle.
- Dryer may refuse to start, or automatically stops if temperature is out of acceptable range.
- Machine may be cold to the touch (if below operating temperature) or unusually warm (if overheated).
Possible Causes
- Temperature sensor reading outside normal range (too cold or too hot) (medium)
- Environmental conditions (ambient too cold) (low)
How to Fix Error CT
DIY Fix Allow the dryer to reach normal ambient temperature
- If the dryer is in a cold room (near freezing), allow it to warm to room temperature for an hour.
- Ensure the laundry room or installation area is within recommended temperature range before operation.
DIY Fix Ensure proper ventilation before re‑testing
- Clear any obstructions from the dryer vent and lint filter.
- Check that airflow is not restricted so the dryer can regulate temperature correctly.
- Restart the dryer once temperature has normalized.
Technician Only Inspect internal temperature sensors and thermostat
- Disconnect power and access thermal sensors.
- Test temperature sensors and thermostat for proper resistance values at room temperature with a multimeter.
- Replace any out‑of‑spec sensors.
Parts needed: temperature sensor(s), thermostat/thermal cutoff
- If the CT error persists after allowing the dryer to stabilize at room temperature and cleaning vents.
- If other codes accompany CT suggesting sensor failure or internal faults.
- If the dryer overheats (feels very hot) repeatedly.
