Why Your Electric Fan is Noisy

Even if you own a white noise fan, abnormal sounds from your unit may indicate a serious problem, so it’s important you address them early. Other issues you may experience due to these issues include slower fan speeds and reduced air quality in your home. Luckily, you can usually silence these irritating noises and prevent other problems with basic maintenance.

Bad Placement

Your standing fan needs a level surface to ensure smooth rotation and balance while cooling your space. Additionally, an uneven floor will cause a noisy wobble if you use the oscillation feature or high-speed settings.

Dirty Blades

Dirt and dust buildup on your fan and blade hub will cause loud squeaking noises and other movements during operation. The excess particles can make the fan’s blade rotation less energy efficient and create a rattling sound due to grit in the motor housing.

Misshapen Blades

If you have plastic blades, they can become chipped or warped, changing the aerodynamics of their spin. This unintended movement might cause the blades to knock against the blade guard and motor shaft.

Loose Parts

Your noisy ceiling fan might have loose screws due to consistent movement or shoddy initial assembly. Go around the unit and hand-tighten any visible screws to fix the annoying sounds.

Low Fan Motor Oil

The fan bearings will dry if your oil level is too low. The dry bearing will make a screeching sound while your fan struggles to maintain its rotation speed. You can top off the oil level through the oil port near the motor shaft.
