DRYER INSPECTION AND CLEANING

Frequency of Exhaust System Cleaning

Every exhaust system must be inspected periodically and 
cleaned to ensure that it is intact and free from lint accumulation. 
The frequency of these inspections will vary, depending on the 
system and usage of the dryer. For single-family usage, an annual 
inspection is recommended. In commercial usage or in multiple 
dryer systems a more frequent inspection is recommended. 
Complaints of long drying times or a hot dryer top indicate the 
need for inspection of the exhaust system.

Inspecting the Exhaust System

1. Disconnect the exhaust duct from the dryer and from the 

exhaust hood (at the exhaust outlet). 

2. Inspect the interior of the duct and remove any lint 

accumulation. 

Be sure that lint is removed from the exhaust hood. Lint 
may collect in the exhaust hood so that the flappers or 
louvers (if installed as part of the exhaust system) will not 
open or close completely.

After cleaning the exhaust hood, check that the flapper or 
louvers move freely.

3. Reassemble the exhaust duct and hood, checking that the 

joints are secure.

4. Operate the dryer and verify that the exhaust air is not 

obstructed in the vent and that there are no leaks in the 
system.

Seal any leaks found.
