How to Keep Your Bathroom Extractor Fan Working Properly

A bathroom extractor fan does more than whisk away steam – it stops mold, keeps air fresh and protects your walls. When the fan stops or gets noisy, you don’t need to panic. Most issues are easy to spot and can be fixed with a few tools.

Common Problems and Quick Fixes

First, check the power. Is the switch on? Does the fan hum but not spin? If it’s silent, the motor may be stuck or the wiring loose. Turn the fan off, remove the cover, and give the blades a gentle clean. Dust and hair are the usual culprits for a weak spin.

If the fan runs but the airflow is weak, the vent pipe might be blocked. Head outside and look at the vent grilles – leaves, nests or debris can choke the flow. A quick brush or garden hose can clear the blockage. Remember to turn the fan off before you start.

Sometimes the fan makes a rattling sound. That often means a loose screw or a worn bearing. Tighten any visible screws and check the motor housing for wiggle. If the bearing is worn, you’ll need a replacement motor, which most DIY‑ers can install with a screwdriver and a bit of patience.

When to Call an Electrician or Professional

If you open the fan and see burnt wires, a smell of smoke, or the motor is hot to the touch, stop immediately. Electrical faults are risky and need a qualified electrician. Also, if the fan is still under warranty, a professional repair saves you from voiding it.

Complex issues like a faulty capacitor or a broken fan blade often require specialised tools. Trying to force a repair can damage the fan further and lead to higher costs. A licensed technician can diagnose the exact part that needs replacement and ensure the wiring complies with UK regulations.

Another situation is a persistent mould problem despite a working fan. The vent may be incorrectly sized for your bathroom, or the fan may be installed in the wrong location. A pro can assess the ventilation design and suggest a larger or more efficient model.

Regular maintenance can prevent most of these headaches. Clean the fan cover every few months, check the vent pipe annually, and listen for any change in sound or airflow. A quick check each season keeps the fan humming and your bathroom dry.
