Kitchen Fan: When to Replace, How to Fix, and DIY Tips

If your kitchen fan is making strange noises, blowing weakly, or just looks tired, it's time to take a closer look. A well‑working fan keeps cooking smells, steam, and grease from building up, and it helps your whole home stay fresh. Below you’ll find clear advice on spotting a failing fan, deciding whether to repair or replace, and a step‑by‑step guide for a DIY swap.

When Should You Replace Your Kitchen Fan?

Most kitchen extractor fans last between five and ten years, but the exact lifespan depends on how often you use it and how well you keep it clean. Look for these warning signs:

  • Weak suction: If steam hangs around after boiling, the motor may be wearing out.
  • Rattling or humming: Loose blades or a failing bearing often cause noisy operation.
  • Bad smell: A burnt odor usually means the motor is overheating.
  • Visible grease buildup: Grease can clog the fan and motor, shortening its life.

When you see two or more of these signs, start planning a replacement. Replacing a fan is usually cheaper than repairing a motor that’s beyond simple fixes.

DIY Replacement: Step‑by‑Step

Changing a kitchen fan yourself can save you a few hundred pounds. You only need a screwdriver, a drill (if you need new mounting holes), and a new fan that matches the size of your existing duct.

  1. Turn off power: Switch off the circuit at the consumer unit to avoid any shock.
  2. Remove the old fan: Unscrew the front cover, disconnect the wiring, and detach the fan from its mounting brackets.
  3. Clean the area: Wipe away grease and dust from the duct and surrounding wall. A clean surface helps the new fan seal properly.
  4. Fit the new fan: Align it with the existing duct, secure it with the brackets, and reconnect the wiring following the colour code (live, neutral, earth).
  5. Test it: Turn the power back on and run the fan. Check that air flows smoothly and that there’s no wobble or noise.

If anything feels uncertain – especially the wiring – call a qualified electrician or a local fan repair specialist. They’ll have the tools and safety knowledge to finish the job quickly.

Regular maintenance can push your fan’s life further. Wipe the exterior weekly, and deep‑clean the interior every six months using a degreaser. A clean fan runs more efficiently and uses less electricity.

When you’re not comfortable doing the swap yourself, look for a tradesperson who lists “extractor fan repair” or “ventilation specialist” in their services. Electricians often handle fan wiring, while a ventilation specialist focuses on ductwork and airflow.

Bottom line: keep an eye on suction strength, noise, and smells. If the fan shows multiple issues, replace it with a matching model and follow the simple DIY steps. A fresh, clean fan will keep your kitchen smelling great and your cooking experience hassle‑free.
