Samsung dryer CLG error code
- Dryer
Samsung dryer CLG (also shown as Cg on some displays) means the internal vent blockage test detected restricted exhaust. DV45R6100 and similar models run this test periodically — a full lint screen or blocked roof cap triggers CLG even when the drum still turns. Treat CLG like a severe AF/airflow warning.

No safety issue
This is a status or lock code, not a hardware fault.
How to fix CLG
- Clean the lint filter and wash it if dryer-sheet residue coats the mesh.
- Inspect the flex hose and exterior vent hood for blockage.
- Remove lint from the blower housing if accessible from the back panel.
- Run a cycle and verify strong airflow outside.
- Schedule professional vent cleaning for long or roof-mounted runs.
Call a pro when: Call a vent pro if exterior airflow stays weak after cleaning the filter and hose.

What CLG means
Vent blockage test found a clogged exhaust — clean the lint filter and outdoor vent.
Likely causes
Lint builds up in the filter, hose, or outdoor vent and trips the airflow sensor.
Check: Clean the lint filter, then check the rear hose and outdoor vent flap for lint or a crushed duct.
Est. cost: $0–$0
Too many elbows or a crushed flex hose chokes airflow even after you clean lint.
Check: Run the dryer and confirm air is blowing outside. Shorten or replace crushed duct.
Est. cost: $0–$40
