Bathroom exhaust fans are easy to overlook, but they can become a serious fire hazard when they aren’t properly maintained. Over time, dust, lint, and other debris can build up inside the fan. This buildup can cause the motor to overheat, wear down electrical components, or even lead to an electrical short. In some cases, an overheated or faulty exhaust fan can start a fire.
Here are a few warning signs to watch for:
- A burning smell coming from the fan
- Unusual buzzing, humming, or grinding noises
- The fan running slower than normal
- Excessive heat coming from the fan
- Visible dust and lint buildup around the cover
How can you help prevent a problem?
Regularly clean your bathroom exhaust fan and remove dust and lint buildup. Make sure the fan is operating properly, and don’t ignore unusual noises or burning smells. If you notice signs of overheating or electrical issues, turn the fan off and have it inspected by a qualified professional.
It’s easy to forget about the small things around the house, but a little maintenance can go a long way in protecting your home.
