When your exhaust fan, a device that pulls steam, smoke, and odors out of your kitchen or bathroom. Also known as extractor fan, it keeps your home air clean and dry stops working right, it’s not just annoying—it can lead to mold, sticky walls, and lingering smells. Most people think exhaust fans just need cleaning, but the real problems are often deeper: a worn-out motor, clogged ducts, or a faulty switch. These aren’t always obvious, and ignoring them makes the fan work harder until it dies completely.
Many exhaust fan failures start with the extractor fan motor, the core component that spins the blades and moves air. Over time, grease and dust build up inside, causing the motor to overheat and burn out. You might hear a loud hum or notice the fan spinning slower than before. Replacing the motor isn’t always expensive, and with the right tools, you can do it yourself in under an hour. But if the fan housing is cracked or the wiring is frayed, it’s safer to replace the whole unit. Another common issue is the kitchen ventilation, the system that includes ducts, filters, and vents working together to remove air. If the duct is blocked by bird nests, grease buildup, or improper installation, even a perfect motor won’t help. Check your ducts at least once a year—especially if you cook often.
Some fans fail because they were never meant to last. Cheap models use plastic bearings and thin wires that break after a few years. If your fan is older than 10 years, it’s likely using outdated parts that are hard to find. In those cases, upgrading to a newer, quieter model often makes more sense than repairing. But if your fan is still solid and just needs a little love, fixing the motor or cleaning the vents can save you hundreds. You’ll also notice better air quality, less condensation on windows, and fewer musty smells.
Below, you’ll find real fixes from people who’ve been there—whether it’s a DIY motor swap, how to test if your fan’s switch is dead, or why your fan runs but doesn’t pull air. These aren’t guesses. They’re the steps that actually work in homes across Warwickshire. No fluff. No theory. Just what to do when your exhaust fan quits.
Exhaust fans can often be repaired instead of replaced. Learn how to diagnose common issues like noisy motors, bad capacitors, and grease buildup - and when to fix it yourself versus calling a pro.
