Samsung Dryer Clg / Cl9 / Cg / C9 error code

Difficulty: Medium · Cost: $0–$150 · Duration: 20–30m

These codes appear after a Vent Blockage test has been run and indicate the exhaust vent is clogged. Clg or Cg means the vent is clogged. C80 or C8 means approximately 80% of the vent is blocked. C90 or C9 means over 90% of the vent is blocked. A heavily blocked vent is a fire hazard — clean the lint screen and exhaust vent immediately.

Common causes

Lint has built up inside the exhaust vent reducing airflow
Lint screen has not been cleaned regularly
Exhaust hose is kinked or crushed
Outside exhaust vent flapper is jammed with lint

How to fix it

1

Remove and thoroughly clean the lint screen
2

Check the exhaust hose for kinks and straighten if needed
3

Inspect the outside exhaust vent flapper and remove any visible lint
4

If the vent is heavily clogged contact a professional dryer vent cleaning service to clear the wall ducts
5

Run the Vent Blockage test again after cleaning to confirm the vent is clear
