How to Clean a Dryer Vent

This task improves efficiency, decreases fire risks and extends the life of your dryer

- BY NINA BRICKO

If your dryer doesn’t dry clothes, or the top is hot to the touch after each use, clogged ductwork may be the culprit. Lint can bypass the removable filter and build up in the dryer duct, restricting airflow and leading to overheating. If the air inside the duct gets hot enough, it can ignite the lint and cause a dryer fire. So be sure to clean your dryer vent at least once a year, or twice if used frequently.

1 UNPLUG THE DRYER

Safely disconnect the dryer by unplugging the power cord and turning off the gas or propane valve.

2 CLEAN THE DRYER LINT TRAP

Clean and vacuum the dryer lint trap using the wand attachment on a vacuum.

3 DETACH THE DUCT

Locate the dryer vent duct. Dryers have a short 4-in. exhaust port on the back that attaches to the ductwork. Remove any worm drive clamps or metal tape to free the vent duct from the dryer. Repeat on the other side of the duct where it meets the wall or window.

If your dryer runs on natural gas, be careful not to disturb the dryer’s gas line when disconnecting the duct.

4 REMOVE THE DRYER VENT COVER

Go outside and remove the dryer vent cover to have uninterrupted access to the entire duct in both directions if you can. Some older single-flap covers may not be removable.
