A vent code means the dryer measured restricted airflow in the exhaust. It is a warning about the duct rather than a broken dryer, and clearing the vent usually ends it.

A dryer vent code means the dryer measured restricted airflow in the exhaust duct, which is a warning about the house venting rather than a broken dryer.
LG dryers with Flow Sense show d80, d90 or d95 when the exhaust duct is about 80, 90 or 95 percent blocked. Whirlpool and Maytag light a Check Vent indicator instead of showing a number.
Both systems check airflow during the cycle. Lint buildup, a crushed hose behind the dryer, a long duct with many bends or a blocked outside hood can all trigger them.
When the dryer runs but produces no heat at all, Samsung HE and LG tE heating codes are more likely. If the vent is clear and drying is still slow, the next step is dryer airflow repair across the state.
LG d80, d90 and d95 report roughly how blocked the duct is, while Whirlpool and Maytag light Check Vent instead of showing a number.
| Brand | Code | Meaning | What to do |
|---|---|---|---|
| LG | d80 / d90 / d95 | Exhaust about 80, 90 or 95 percent restricted | Check it yourself first |
| Whirlpool / Maytag | Check Vent light | Restricted exhaust airflow detected | Check it yourself first |
| Samsung | Check Filter | Lint filter reminder or restricted airflow | Reset and retry |
Codes are listed for identification. Meanings vary by model, so confirm the code in your owner’s manual.
Vent warnings are the only dryer codes that measure the house rather than the dryer. That makes them a useful early warning, because a restricted duct raises drying time and fire risk long before a part fails.
LG Flow Sense estimates how blocked the exhaust is and shows d80, d90 or d95 for roughly 80, 90 or 95 percent restriction. The dryer keeps running, but drying times climb.
Long duct runs with several elbows can trigger d80 even when they are clean, so the duct length matters as much as lint.
Whirlpool, Maytag and Kenmore models built by Whirlpool light a Check Vent indicator when they sense restricted airflow. It usually shows after the first few minutes of a cycle and clears once airflow returns to normal.
Samsung dryers show Check Filter as a reminder and on some models when airflow drops. If the filter is clean and the warning stays, inspect the duct and outside hood.
Cleaning the duct from the dryer to the outside hood clears most vent codes in one pass.
A vent code needs outside help when the duct cannot be reached or stays blocked after cleaning. Stop running the dryer and get help when:
Error Code FAQs
Vent code questions center on what the warning measures and how safe it is to keep drying with it showing.
d90 means the dryer measured the exhaust duct as about 90 percent blocked. Clean the lint screen, the hose behind the dryer and the outside vent, then run a cycle.
The dryer detected restricted airflow. Clear lint from the screen, the hose and the outside hood. The light should go off once airflow is normal.
Clean the lint screen every load. Many manufacturers suggest cleaning the full duct at least once a year, or sooner in a busy household.
Yes. Every bend and extra foot of duct reduces airflow. Many manufacturers list a maximum duct length in the installation guide.
It will run, but airflow is badly restricted and lint can overheat. Clean the duct before using it again.
Describe how long the duct is and where it leaves the house.
