Unlikely fire hazard: Dirty bathroom fans

When you add dust buildup to a bathroom fan motor, you get a fire hazard. When a fan is clogged with lint and dust, airflow can be restricted. This makes the fan motor run hot, which can lead to trouble. 

Bathroom exhaust fans should be cleaned regularly per the manufacturer’s instructions—usually about twice a year. When cleaning a bathroom fan, you should remove the cover and be sure to clean lint from around the motor paying close attention to airflow areas. Wash the fan cover in warm, soapy water to remove all dust and lint. If there is any mold growing on the cover, add bleach to the cleaning mixture. Remember, bathroom fans aren’t meant to run for long periods of time. Consider installing a timer switch to limit unnecessary use.
