Noisy bathroom fan: cleaning + simple fixes (no electrical work)

Bathroom fans get loud when the cover is dusty, the grille vibrates, or the fan is struggling. In rentals, stick to external cleaning and basic checks—no wiring.

Important: These guides focus on low-risk, reversible steps. If your lease forbids a modification (or the task involves gas/electrical/structural work), stop and contact maintenance.

Safe cleaning steps

Turn the fan off and let it stop completely.
Remove the grille/cover (most pull down and unclip).
Wash the cover with warm soapy water; dry fully.
Vacuum dust from the visible fan housing (don't reach into wiring).
Reinstall and test.

Reduce vibration noise

Make sure the grille is seated evenly (not twisted).
Check if the grille springs are bent; re-seat them.
If the fan hums loudly even after cleaning, it may need maintenance (bearing/motor).

When to call maintenance

Grinding sound, strong burning smell, or fan stops frequently.
Fan doesn't remove steam (mirrors stay foggy long after showers).
Any signs of water leakage around the fan.
