Samsung Dryer Clg Error Code
Vent blockage detected
Applies to: Models with Vent Sensor / Vent Blockage Test. May also appear as Cl9, Cg, C9, C80, C8o, C8, C90, C9o.
What's going on
On Samsung dryers with a vent sensor, the Clg code (sometimes shown as Cg) means the dryer has detected a blocked exhaust vent. A blocked vent traps hot air and lint, which is a fire risk. Stop using the dryer, unplug it or switch off its breaker, and have a qualified appliance technician or dryer vent professional inspect it.
A dryer pushes hot, damp air and fine lint out through a duct to a hood on the outside of your home. Some Samsung dryers have a Vent Sensor that checks how freely that air is flowing. When the airflow is too restricted, the dryer shows a vent warning code.
Related codes show how severe the blockage is. C80 or C8 means the vent is partly clogged. C90 or C9 means it is nearly fully clogged. Clg or Cg means the vent is clogged. This applies to Samsung models with the Vent Sensor or Vent Blockage Test feature. Codes can differ between model generations, so confirm the meaning with your model number.
This matters because trapped heat builds up inside the dryer and duct, and lint is very flammable. A clogged vent is a common cause of dryer fires.
Likely causes
- exhaust vent duct — Lint builds up inside the duct over time, or the duct gets crushed, kinked, or disconnected behind the dryer. Either one blocks the flow of hot air.
- lint filter — A filter packed with lint or coated with residue restricts airflow at the start of the vent path. The sensor can read this as a blockage.
- exterior vent hood — The hood outside can get clogged with lint, bird nests, debris, or ice, or its flap can stick shut. Air then cannot leave the home.
The same code can mean different things on different model generations. Check the model number on your dryer's rating plate before ordering parts.
Can you fix it yourself?
Usually a straightforward DIY fix.
When to call a technician
Because this code points to a fire risk, stop using the dryer and keep it unplugged or its breaker switched off. Have a qualified appliance technician or dryer vent cleaning professional inspect and clear the full vent system before the dryer is used again.

Common questions
- What does Clg mean on a Samsung dryer?
- Clg means: Vent blockage detected. The most likely parts involved are exhaust vent duct, lint filter, exterior vent hood.
- Is it safe to keep using the dryer?
- This code can mean the appliance is overheating. Turn it off at the circuit breaker (or unplug it if you can do so safely) and call a qualified technician. Do not try to diagnose or repair this yourself.
- How much does it cost to fix Clg?
- A typical overheating / vent blockage repair costs about $100–$250 nationally, parts and labor included. This is a reference range, not a quote — local prices vary.
- Should I repair or replace my dryer?
- Repair usually makes sense. Even the high end of this repair stays under $500, about half the price of a typical new dryer.
- Can I fix Clg myself?
- Usually a straightforward DIY fix.
- Can I keep using my Samsung dryer while it shows the Clg code?
- No. A clogged vent lets heat and lint build up, which can start a fire. Keep the dryer off and unplugged until the vent has been inspected and cleared.
- What is the difference between Clg, C80, and C90 on a Samsung dryer?
- They all warn about a blocked vent. C80 (or C8) means partly clogged, C90 (or C9) means nearly fully clogged, and Clg (or Cg) means the vent is clogged. Treat any of these as a reason to stop using the dryer and have the vent checked.
