When your noisy exhaust fan, a ventilation device in kitchens or bathrooms that pulls out steam, smoke, and odors. Also known as extractor fan, it’s meant to work quietly in the background. When it starts screaming, rattling, or buzzing, it’s not just a nuisance—it’s telling you something’s broken inside. Most people ignore the noise until the fan stops working entirely. But that loud grinding or whining? That’s your warning sign.
The extractor fan motor, the core component that spins the fan blades to move air is usually the culprit. Over time, dust builds up, bearings wear out, or the motor gets misaligned. A loose mounting bracket can make it rattle against the ceiling or wall. Even a clogged grease filter can force the motor to work harder, creating extra noise. You don’t need to be a technician to spot these issues—listen closely. A high-pitched whine? That’s the motor struggling. A rhythmic clunk? Something’s loose or bent.
Some folks try to fix it with oil or tape, but that’s a band-aid. The real fix often means replacing the extractor fan motor, the part that powers the fan and wears out over years of constant use or the whole unit. If your fan is over 8–10 years old, replacement is usually cheaper than repair. Newer models are quieter, more energy-efficient, and come with better filters. But if it’s still under warranty or the housing is in good shape, swapping just the motor can save you money.
