Samsung Dryer C1 Error Code

Vent test could not run. Here is what it means and how to clear it, easiest fix first.

C1
Easy DIY fix

These are vent blockage test results that mean the test could not run properly rather than a clog. C1 or CL1 means laundry was detected in the drum. Ct means the dryer is too cold (below freezing) or too warm (above 104°F (40°C)) to test accurately.

Also shown as CL1. Ct is listed with the same group of test results.

Safety first: unplug the dryer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung C1

  1. Empty the drum

    For C1 or CL1, remove all laundry and any racks from the drum and run the vent test again.

  2. Let the dryer reach room temperature

    For Ct, let the dryer sit at normal room temperature for about an hour, then run the test again.

When to call a technician

If C1 appears with an empty drum, or Ct continues in a normal-temperature room, book a repair.
