If you’ve ever cooked a big meal, you know a good extractor fan is a kitchen lifesaver. But like any appliance, it won’t run forever. Knowing the factors that wear it out helps you avoid costly breakdowns and decide whether repair or replacement makes sense.
Most residential extractor fans are built to last between 7 and 12 years. The exact number depends on three main things: usage, cleaning frequency, and the type of filter you use. Heavy‑duty cooking, especially with lots of oil fumes, forces the motor to work harder, shaving years off its life. Skipping filter cleaning lets grease build up, which blocks airflow and makes the motor overheat. Metal mesh filters need a wash every 1‑2 months, while carbon filters should be swapped out every 6‑12 months, depending on brand.
Another hidden factor is ventilation. If the duct is too long, has sharp bends, or isn’t sealed properly, the fan has to push more air than it’s designed for. That extra strain can burn out bearings early. Finally, power surges or incorrect wiring can fry the motor in minutes. Using a surge protector or hiring a qualified electrician for installation eliminates this risk.
Keeping your extractor fan happy is easier than you think. First, turn it off and let it cool, then remove the filter. A quick rinse under warm water with a mild detergent clears most grease. For stubborn buildup, let the filter soak for 15 minutes. Dry it completely before reinstalling – a wet filter can cause rust.
Next, inspect the fan blades and motor housing for dust. A soft brush or a low‑speed vacuum can clear debris without damaging parts. While you’re at it, check the duct for blockages. A flashlight will show you if lint or insulation is clogging the path. If you spot any cracks or gaps, seal them with foil tape.
Run the fan on high for a few minutes after cleaning. This dries any remaining moisture and lets you hear the motor. Any grinding or rattling noises mean the bearings may need lubrication or replacement. Most modern fans have sealed bearings, so it’s best to call a professional at this point.
When repair costs creep above £150 or the fan is older than 10 years, replacement is usually smarter. New fans are more energy‑efficient and often come with better filtration. A typical 60‑cm kitchen hood costs £80‑£150 plus installation, which is a fraction of the price of an old unit that keeps breaking down.
