Extractor Fan Not Working? Common Causes and Fixes

When your extractor fan, a ventilation device used in kitchens and bathrooms to remove steam, smoke, and odors. Also known as extraction fan, it's a small but vital part of your home’s air quality system. stops pulling air, it’s not just annoying—it can lead to mold, lingering smells, and even damp walls. Most extractor fans fail for one of three reasons: the motor burns out, the capacitor dies, or the fan blades get clogged with grease and dust. It’s rarely a wiring issue unless you’ve recently done work near the unit.

The motor, the core component that spins the fan blades is the most common culprit. If you hear a hum but no airflow, the motor’s seized or overheated. A capacitor, a small component that gives the motor its initial kick to start spinning can also fail silently—no noise, no movement. Both are cheap to replace, often under £20, and easy for a handy homeowner to swap. Then there’s the grease filter, the removable mesh that catches cooking residue before it reaches the fan. If it’s been a year since you last cleaned it, you’re basically running the fan through a clogged straw. Clean it monthly. Replace it if it’s warped or cracked.

Don’t assume you need a full replacement. Most extractor fans last 10–15 years, and even older units can be revived with a new motor or capacitor. You’ll save hundreds compared to buying a new unit and paying for installation. Check the model number on the back—many parts are universal across brands like Zephyr, Extract, and Vent-Axia. If your fan is wired into the lighting circuit, make sure the switch isn’t faulty too. A broken pull cord or wall switch can look just like a dead fan.

Just the most common reasons your extractor fan stopped working, what to check first, and how to fix it without calling a pro. Some fixes take 10 minutes. Others need a bit more time—but they all save money. Let’s get your kitchen breathing again.
