Samsung Dryer Error Code Ct
The dryer is protecting itself because the air around it is outside the range it is designed to work in, either freezing cold or hotter than 104°F. It is an environment warning rather than a failed part; let the room return to a normal temperature and the code should go away on its own.
Common causes
- Dryer installed in an unheated space during freezing weather
- Air around the dryer hotter than 104°F (40°C)
What to check, in order
- Leave the dryer sitting at normal room temperature for about an hour, as Samsung directs, then try again.
- If the dryer is in a garage or outbuilding in winter, warm the space up or wait for milder conditions before running it.
- Once the surroundings are back at a normal temperature, start a cycle to confirm the code has cleared.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
This display is not a fault, so there is normally nothing to book. Call a technician only if the machine also behaves abnormally, or if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code Ct, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
