When your extractor fan, a ventilation device installed in kitchens and bathrooms to remove steam, smoke, and odors. Also known as extraction fan, it plays a quiet but essential role in keeping your home healthy and mold-free. stops working, it’s not just annoying—it can lead to damp, bad air, and even long-term damage to walls and ceilings. Most extractor fans fail for simple reasons: a clogged filter, a worn motor, or a broken switch. You don’t always need a technician. Many fixes can be done in under an hour with basic tools.
One of the most common issues is dust and grease buildup, a sticky layer that clogs the fan blades and reduces airflow. If your fan is loud or spins slowly, clean the grille and remove the filter. Most filters are washable—just soak them in warm soapy water, rinse, and let them dry. A dirty fan works harder, wears out faster, and uses more electricity. Another frequent culprit is the fan motor, the part that spins the blades and often fails after years of constant use. If the fan hums but doesn’t turn, the motor is likely dead. Replacing it costs less than £50 and takes about 30 minutes if you’re comfortable with a screwdriver.
Don’t ignore a fan that turns on and off randomly—that’s usually a faulty switch or wiring, often caused by moisture damage or loose connections. Check the power supply at the fuse box and look for frayed wires behind the unit. If you smell burning or see discolored plastic, stop using it immediately. Electrical faults in extractor fans can be dangerous, and it’s better to call a qualified electrician than risk a fire.
