Reading the Ct result
Ct does not point to a broken part. It is an outcome of the Vent Blockage test, and it tells you the test ran while the dryer sat outside its allowed temperature window: colder than freezing, or warmer than 104°F.
How to recover
Let the dryer settle at normal room temperature for a full hour.

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.
