Kitchen Extractor Fan Fix: Common Problems and Quick Solutions

When your kitchen extractor fan, a ventilation device that pulls smoke, steam, and cooking odors out of your kitchen. Also known as range hood, it keeps your air clean and prevents mold from building up. stops working, it’s not just annoying—it’s a health risk. Grease and moisture linger, walls get sticky, and your kitchen starts to smell like last night’s fried food. The good news? Most extractor fan failures are simple to fix, and you don’t always need an electrician.

The biggest culprit? grease buildup, a thick layer of oil and residue that clogs the fan blades and motor over time. It’s not just dirt—it’s a silent killer of airflow. If your fan is louder than usual or barely spinning, chances are grease has gummed up the works. Then there’s the extractor fan motor, the heart of the unit that spins the blades. These motors wear out after 8–12 years, especially if they’re constantly running. Wiring issues, loose connections, or tripped circuit breakers also show up often, especially in older homes with outdated electrical systems.

You might think you need to replace the whole unit, but in most cases, cleaning the fan, replacing the motor, or fixing a loose wire brings it back to life. Many people replace their extractor fan because they don’t know how easy it is to clean the grease filters or test the motor with a multimeter.
