Bathroom Fan Maintenance & Repair Guide

That little fan above your shower does more than keep steam away – it stops mould, stops bad smells and helps your bathroom stay fresh. Over time the motor can get dusty, the blades can wear out, and the noise can get louder. The good news? Most of the stuff that goes wrong is easy to spot and fix, and you don’t always need a pricey engineer.

How often should you clean your bathroom fan?

Cleaning the fan once a year is a solid rule of thumb. If you take hot showers every day, aim for every six months. Turn the power off at the breaker, remove the cover (most clips just pop off), and wipe the blades with a damp cloth. Use a soft brush to clear any dust from the motor housing. A quick vacuum on the vent pipe helps keep airflow smooth. When you finish, put everything back and you’ll notice the fan runs quieter and pulls more air.

Common problems and quick fixes

Fan won’t turn on. First, check the switch – sometimes it’s just a loose connection. If the switch feels fine, look at the fuse or circuit breaker. A tripped breaker is a common culprit. If the power is good and the fan still stays silent, the motor may have burned out and will need replacement.

Noise that sounds like a buzzing or rattling. Dust can make the motor hum, and loose screws cause rattles. Tighten any visible screws and give the motor a good clean. If the buzzing stays, the motor bearings might be wearing out – that’s a sign it’s time for a new fan.

Weak airflow. Over time, the vent duct can collect lint and debris. A flexible brush or a vacuum hose can pull the blockage out. Also, check that the external vent hood isn’t blocked by leaves or bird nests. Clear those and you’ll feel a noticeable boost in performance.

When you’ve tried these steps and the fan still misbehaves, it’s smart to call a professional. A certified gas engineer can safely replace the motor, check wiring, and make sure the fan meets local ventilation standards – especially important if you have a boiler or gas heater nearby.

Regular maintenance not only extends the life of your fan but also helps your whole bathroom stay dry and mould‑free. A clean, well‑working fan reduces humidity, which in turn protects paint, tiles and wooden frames. So set a reminder on your phone, grab a screwdriver once a year, and give your fan a quick once‑over.
