On the covered Samsung dryer platform, Ct means vent blockage test could not run because the dryer is below freezing or above 104 degrees F. First, bring the dryer to room temperature. Samsung says the dryer is below freezing or above 104 degrees F.
Differential
Likely causes of “Samsung dryer code Ct”, and how to tell them apart
- 1
A dryer that is too cold or too hot to test
What separates it Ct shows when you start the vent blockage test
How to confirm Samsung says the dryer is below freezing or above 104 degrees F
- 2
A dryer that has just been used
What separates it The dryer will not enter test mode after a cycle
How to confirm Samsung says the dryer must be sufficiently cooled down before the test
- 3
A vent that is blocked or crushed
What separates it The test cannot finish and the exhaust hose behind the dryer is bent or packed with lint
How to confirm Pull the dryer forward and check the exhaust hose for kinks and lint before you repeat the test
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact characters shown on the display: Ct
- The room temperature where the dryer sits
- Whether the dryer was just used

Correct only the documented fault domain
ReversibleSamsung says to wait one hour with the dryer at room temperature and try again, and if the error continues to request service from its Support Center. This is a sensor-range limit on the test itself, not a fault with the dryer or the vent, so a Ct code from an unheated garage or a very hot laundry closet is not evidence anything needs repair — it means the test cannot get a reliable reading at that temperature, and it will run normally once the room is within range..
Let it reach room temperature
ReversibleWait one hour with the dryer at room temperature, since Ct means the internal temperature is below freezing or above 104 degrees F.
Cool a hot dryer
ReversibleIf the dryer was used or just installed, run the Air Fluff cycle for several minutes to reduce the internal temperature.
Repeat the test
ReversibleEmpty the drum, close the door and run the vent blockage test again.
Model-specific
What is true of this model and not of its siblings
- Displayed as
- Ct.
Stop boundary
When this stops being a self-service repair
- !Unplug the dryer before you inspect anything, with the full model number and exact code ready
- !Request service if Ct continues after the dryer has been at room temperature

Common questions
What does Ct mean on a Samsung dryer?+
Vent blockage test could not run because the dryer is below freezing or above 104 degrees F.
Is the dryer broken?+
No; it is a test condition.
Does Ct mean the vent has failed the test?+
No; Samsung ties Ct to conditions that stop the test from running, so clear the conditions and repeat it before assuming the vent is blocked.
