If your bathroom fan is making a racket, barely moving air, or just won’t turn on, you’re not alone. A faulty fan can leave your bathroom damp, smelly, and prone to mould. The good news? Most problems are simple enough to tackle yourself, and you only need a pro when the electricity gets involved.
First, get a quick idea of what’s causing the trouble. The most common culprits are a dirty motor, a blocked vent, a loose connection, or a worn‑out bearing. Dust and hair love to build up in the motor housing, choking the fan blades and making the motor work harder. Over time the motor bearings can wear out, leading to whining or a complete stop.
Another often‑overlooked issue is the vent pipe. If the pipe is clogged with debris or the outside grille is blocked by leaves, the fan can’t push air out. You’ll feel the airflow drop and notice more moisture lingering in the room. Finally, electrical problems like a tripped breaker, a loose wire, or a burnt‑out fuse can leave the fan dead. If the fan doesn’t respond at all, this is probably why.
Start with a safety check: turn off the power at the fuse box, then pull the fan cover off. Most covers snap off with a gentle twist. Give the motor a good cleaning with a soft brush or a vacuum on low power. Remove any hair, dust, or lint you see. If the blades look stiff, a few drops of light oil on the bearing (if you can see it) can help.
Next, inspect the vent pipe. Go outside and look at the vent grille – clear away any leaves, nests, or cobwebs. If you can, detach the pipe and blow air through it to make sure it’s clear. A short, flexible brush works well for a quick scrub.
Check the wiring. With the power still off, look for any loose screws on the terminal block and make sure the wires are snug. If you see a burnt smell or blackened spots, stop and call an electrician – that’s a sign of a deeper electrical fault.
If the fan still won’t run, it might be the motor itself. A dead motor usually hums or makes a high‑pitched whine before stopping. In this case, replacing the motor or the whole fan unit is the next step. Most fans sell for under £100 and come with simple plug‑in connectors.
When you’ve tried the above and the fan is still noisy or weak, it’s time to call a professional.
