What Does Error CLG Mean?

The Samsung dryer error code CLG signifies a control lock issue, indicating a potential clog or airflow restriction in the exhaust system. This can lead to an unresponsive control panel and reduced drying efficiency. Symptoms include weak airflow at the exterior vent, prolonged drying times, and the dryer diagnostic test reporting a vent blockage. Addressing this issue involves cleaning the exhaust vent and running a blockage test to ensure proper airflow.

Common Symptoms:

  • Dryer diagnostic or vent blockage test reports a clog
  • Dryer stops heating or runs much longer than expected
  • Airflow seems weak at the exterior vent while drying

Possible Causes

  • Clogged or restricted exhaust vent/duct (high)
  • Internal lint buildup beyond external vent (medium)
