Got a noisy or dead extractor fan in your bathroom or kitchen? You’re not alone. These little fans keep moisture out, stop mould, and keep the air fresh. When they quit, the whole room feels sticky. The good news? Some fixes are easy, but others need a qualified plumber. Let’s break down what you can try yourself and when it’s smarter to pick up the phone.
First, make sure the fan actually has power. The simplest mistake is a tripped circuit breaker or a blown fuse. Flip the breaker back on or replace the fuse, then test the fan. If it still won’t run, listen for a hum. A humming fan usually means the motor is trying but is stuck – a dirty blade can cause that.
Next, clear out any dust or grime. Over time, grease and bathroom soot build up on the fan blades and motor housing. Turn the power off, remove the cover (usually a few screws), and wipe everything with a damp cloth. If the blades are greasy, give them a gentle scrub. A clean fan spins more easily and is quieter.
Another quick check is the switch. Some fans are wired to a wall switch, others have a pull‑chain. Test the switch with a voltage tester or try a different switch if you have one. A faulty switch can make the fan look broken when the wiring is fine.
If the fan still doesn’t work after these steps, it might be a burnt‑out motor or a broken capacitor. Those parts need special tools and knowledge to replace safely.
Even though extractor fans look simple, they’re often connected to the home’s electrical and ventilation system. A plumber knows the local building codes, especially when the fan is ducted to the outside. Incorrect wiring can cause short circuits, fire hazards, or water leakage if the duct isn’t sealed right.
When the motor has failed, the replacement must match the fan’s power rating and size. A plumber can source the correct part and install it without damaging surrounding plaster or tiles. They also check the vent pipe for blockages – a common hidden issue that causes fans to overheat.
Safety is the biggest reason to call a pro. Working with live electricity and tight ceiling spaces can lead to injury if you’re not trained. Plumbers are also insured, so if anything goes wrong, you’re covered.
In short, try the easy checks first: power, cleaning, switch. If those don’t bring the fan back, schedule a plumber. They’ll diagnose motor or wiring problems, ensure the duct is clear, and get your fan humming again – safely and fast.
Remember, a well‑maintained extractor fan does more than keep steam away. It protects your walls, stops mould, and helps your home stay healthy. Keep an eye on it, clean it once a year, and don’t ignore strange noises. When in doubt, a plumber’s call is the quickest route back to fresh, dry air.
