Extractor fans play a crucial role in maintaining the ventilation of your home, but they occasionally break down. Learning to fix a broken extractor fan can save you money and extend the life of the appliance. This article will guide you through identifying the problem, gathering necessary tools, and troubleshooting the common issues associated with malfunctioning extractor fans.
Kitchen Exhaust Tips: Keep Your Kitchen Fresh and Safe
Ever wondered why your kitchen always smells like fried food even after you turn off the stove? Most of the time it’s a tired or poorly placed exhaust fan. A good kitchen exhaust does more than remove smoke – it protects your cabinets, stops grease buildup, and keeps the air comfortable. Below are the practical tips you need to get the most out of your fan without calling a pro every week.
How to Tell When Your Extractor Fan Needs Attention
First, notice the signs. If the fan sounds weaker, makes rattling noises, or the kitchen stays steamy after cooking, something is off. A quick visual check helps: look for grease film on the blades and inside the vent cover. Even a thin layer can choke airflow.
Another easy test is the paper test. Hold a piece of paper near the vent while the fan runs. If the paper doesn’t lift, airflow is low and the fan probably needs cleaning or a filter change.
Our article How Often Should You Replace Your Extractor Fan? Expert Tips & Lifespan Facts explains that most fans last 5‑7 years if you clean them regularly. If your unit is older than that, start planning a replacement.
DIY Cleaning and Simple Repairs
Cleaning a kitchen exhaust fan is easier than you think. Turn off the power, unscrew the cover, and soak the metal parts in warm, soapy water for ten minutes. Use a soft brush to get rid of stuck grease. Rinse, dry, and re‑assemble.
If the fan still feels weak after cleaning, check the motor. A humming sound without blade movement usually means the motor is jammed. In many cases you can free it by gently turning the blade with a wooden stick. If that doesn’t work, the motor may need a professional replacement – see our guide How Hard Is It to Replace an Extractor Fan? Step‑by‑Step DIY Guide for a simple walk‑through.
When you finally decide to replace the fan, consider these three quick points:
- Size matches the hood. Look at the duct diameter and make sure the new fan fits.
- Airflow rating. Choose a fan that moves at least 100 CFM per linear foot of hood width.
- Noise level. Fans are rated in sones – lower numbers mean quieter operation.

Finally, remember to keep the external vent clear. Leaves, nests, and snow can block airflow and force the fan to work harder. A quick check every few months saves you from costly repairs later.
By cleaning regularly, listening for odd noises, and watching the fan’s performance, you’ll extend its life and keep your kitchen smelling fresh. Got more questions?
