Kitchen Extractor Fan: How to Fix, Replace, and Keep It Working

If your kitchen smells like fried food all day or the fan makes a rattling noise, it’s probably time to look at the extractor. A good fan clears steam, smoke, and odors, so you don’t have to hold your breath while cooking. Below you’ll get straight‑to‑the‑point advice on when to repair, when to replace, and how to keep the fan humming without a hitch.

When to Replace Your Kitchen Extractor Fan

Not every hiccup means a brand‑new fan. But there are clear signs that a replacement is smarter than a fix. If the motor hums but the blades don’t spin, the internal bearings are likely worn out – most fans aren’t built for a cheap part swap. A burnt‑out motor usually costs more in labour than a new unit.

Another red flag is a drop in suction. Over time, grease builds up on the blades and the ductwork, reducing airflow. If cleaning doesn’t bring the power back, the fan’s capacity may be below the size needed for your kitchen. In that case a larger, more efficient model will save energy and cut cooking fumes.

Look at the age of the fan too. Most kitchen extractors last 8‑10 years with regular care. If yours is older and you’re already paying for multiple repairs, the price difference between fixing it and buying a new, quieter, energy‑saving model shrinks fast.

DIY Maintenance and Simple Repairs

Before you call a pro, try these quick steps. First, turn off the power at the breaker – safety first. Remove the filter; most kitchen fans use a metal mesh that can be rinsed under hot water. If the filter is heavily greased, soak it in a dish‑soap solution for 15 minutes, then scrub with a soft brush.

Next, check the fan blades. Loose screws cause wobble and noise. Tighten any loose fasteners with a screwdriver. While you’re there, give the blades a wipe‑down with a damp cloth; built‑up grime adds weight and can strain the motor.

If the fan still runs weakly, the duct may be clogged. Detach the duct from the vent (usually a simple clip) and blow out any dust or grease with a shop‑vac. Re‑attach and test the fan. Often a clean duct restores most of the lost suction.

For motor issues, a quick reset can help. Some fans have a reset button on the motor housing – press it after the fan cools down. If the motor still won’t start, it’s likely a capacitor problem. Swapping a capacitor is a cheap fix, but you’ll need basic electrical knowledge. If you’re unsure, it’s safer to let a qualified technician handle it.

Regular upkeep makes a big difference. Aim to clean the filter every month if you cook a lot, and give the fan blades a wipe‑down quarterly. A yearly professional service can check the motor and wiring, catching problems before they become costly.

Bottom line: a well‑maintained extractor fan keeps your kitchen fresh and your cooking enjoyable. Simple cleaning, tightening, and occasional duct checks solve most issues. When the fan’s motor fails, the blades are bent, or suction is permanently low, swapping the unit saves time and money in the long run. Whether you DIY or call a pro, you now have a clear checklist to get your kitchen breathing easy again.
