Samsung Dryer Error Code Ct

CtSamsung Dryer

What this code means

The internal temperature of the dryer is too low (below 32°F) or too high (over 104°F) and therefore vent blockage cannot be detected.

First step from the service manual

Leave the dryer at room temperature (41-95°F) for an hour and check again.

Next steps: diagnose the root cause

1
Verify the error code is active

Power cycle the unit and see if the code returns. If it does, the fault is persistent and requires diagnosis.

2
