Kitchen Extractor Fan: Lifespan, Maintenance & Repair Tips

If you cook often, you know a good extractor fan is a kitchen must‑have. It pulls away steam, grease and cooking smells, keeping the air fresh and safe. But like any appliance, fans wear out over time. Below you’ll get straight‑forward advice on how long they normally last, what you can do to keep them humming, and when it’s time to call a pro.

How Long Do Extractor Fans Last?

Most residential kitchen fans give you between 7 and 12 years of solid service. The exact number depends on a few simple factors:

• Usage frequency. Running the fan every night shortens its life faster than using it once a week.
• Cleaning routine. Grease builds up on the blades and filter, making the motor work harder.
• Quality of the unit. Higher‑grade fans with sealed bearings tend to outlast cheap models.
• Ventilation setup. If the duct is long or has many bends, the motor has to push air further, which adds wear.

When a fan starts to get noisy, loses suction, or the lights flicker, those are classic signs it’s aging. Spotting the problem early can save you a costly replacement.

Simple Maintenance Steps to Keep Your Fan Working

Maintenance isn’t rocket science – a few quick chores each month go a long way.

1. Turn it off and unplug. Safety first.
2. Remove the filter. Most kitchen fans have a metal or charcoal filter that slides out.
3. Soak in warm, soapy water. Let it sit for 10‑15 minutes, then scrub gently with a soft brush.
4. Wipe the blades. Use a damp cloth; avoid harsh chemicals that can corrode the metal.
5. Check the vent duct. Look for visible blockages or a build‑up of dust. A quick vacuum can clear it.
6. Re‑assemble and test. Turn the fan back on and listen. It should run smoother and sound quieter.

Doing this every 4‑6 weeks keeps the motor cool and the airflow strong. If your fan has a charcoal filter, replace it every 6 months – they’re cheap and make a big difference.

When you’ve tried the basics and the fan still under‑performs, it’s time to look deeper. A motor that hums but doesn’t spin usually means a worn bearing. In that case, a professional can replace the motor for a fraction of the cost of a whole new unit.
