If your bathroom or kitchen fan is humming, rattling, or just won’t turn on, you’re not alone. A faulty extractor fan can make a room feel clammy and cause mould, but most issues are easy to spot and fix. Below we’ll walk through the most common problems, quick DIY tricks, and the signs that it’s time to hand the job over to a pro.
First, check the power. A tripped breaker or a loose plug is the simplest culprit. Flip the kitchen or bathroom circuit breaker back on and make sure the fan’s plug is seated firmly. If the fan still won’t start, test the wall switch with a voltage tester – a dead switch means you’ve nailed the problem without opening the unit.
Next, give the fan a good clean. Over time, grease, dust, and hair build up on the motor and blades, slowing the fan down or causing a grinding noise. Turn off the power, remove the cover (usually a few screws), and wipe the blades with a damp cloth. Vacuum the motor housing to clear any debris that might be jamming the bearings.
Another frequent issue is a worn‑out motor or broken fan belt (if your model uses one). When the fan runs but you hear a whirring sound and no airflow, the belt may have slipped or snapped. Locate the belt, check for cracks, and replace it with a matching size from a local DIY store. Motor replacement is a bit more involved; if you hear a burning smell or the fan sputters before stopping, the motor likely needs swapping.
Sometimes the problem is the fan’s vent itself. Blocked ducts or an outdoor grille clogged with leaves or debris can choke airflow. Remove the external grille, clear any blockage, and check that the duct isn’t crushed or kinked. A clear path means the fan can push out moist air efficiently again.
If you’ve tried the basics and the fan still misbehaves, it’s time to call in the experts. Electricians are the right choice when the issue is wiring, a faulty switch, or a motor that requires disassembly. They have the tools to safely test live circuits and replace components without risking a shock.
Plumbers can step in if the fan is a part of a larger ventilation system that ties into your roof or if you need a new duct installed. They also know the building codes in Nuneaton, ensuring any new work meets safety standards.
Lastly, consider the age of the fan. A unit older than 10‑12 years may be more costly to repair than replace, especially if parts are hard to find. A professional can advise whether a fresh, energy‑efficient fan would save you money in the long run.
In short, start with power checks, cleaning, and simple parts checks. If the fan still won’t cooperate, don’t gamble with electrical work—call a qualified electrician or plumber. Keeping your extractor fan humming along not only protects your home from moisture damage but also saves you time and money in the long run.
