Error codeCt
ApplianceDryer
Quick answer
Ct appears after a Vent Blockage test when the dryer is too cold or too hot; wait one hour at room temperature.
Model compatibility: Samsung reuses codes across series and model years, so Ct may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Ct is a Vent Blockage test result: the dryer is below freezing or above 104°F.
A Ct result on a Samsung dryer means the Vent Blockage test could not run properly because the dryer is below freezing or above 104°F. It only appears after that test.
What to do
Leave the dryer at room temperature for one hour, then try the test again. If the error continues, request service.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
