Fixing Extractor Fans: Simple Steps and Pro Tips

Extractor fans keep your kitchen and bathroom fresh, but they can go quiet or smell funny. Most issues are easy to spot and fix, so you don’t always need a pricey call‑out. Below we walk through the typical problems, a quick DIY replacement, and the signs that a professional is the safe bet.

Common Reasons an Extractor Fan Stops Working

First, check the power. A tripped circuit breaker or a blown fuse is the simplest culprit. If the fan still won’t spin, the motor is likely the problem. Over time, grease, dust, and moisture can coat the blades and motor, causing it to stall.

Another frequent issue is a broken or loose fan belt (on belt‑driven models) or worn bearings. You might hear a humming noise with no air movement – that’s the motor straining.

Lastly, look at the fan’s vent pipe. A clogged duct filled with fat, lint, or mould will choke airflow and make the motor overheat. Regular cleaning keeps the system humming.

DIY Guide: Replacing a Kitchen Extractor Fan

If you’ve identified a faulty fan, you can swap it out in under an hour. Gather a screwdriver, a voltage tester, a new fan that matches the size and airflow rating, and safety gloves.

1. Turn off the electricity. Switch off the circuit breaker for the kitchen or bathroom. Use the tester to confirm the wires are dead.

2. Remove the old unit. Unscrew the mounting brackets, disconnect the wiring (note which wire goes where), and pull the fan away from the ceiling or wall.

3. Clean the vent. While the opening is exposed, vacuum out any built‑up grease or dust. A quick brush‑through keeps the new fan running longer.

4. Install the new fan. Attach the new unit to the brackets, reconnect the wires matching the colour code, and secure everything tightly.

5. Test it. Switch the breaker back on and turn the fan on. You should feel airflow and hear a steady hum. If anything sounds odd, double‑check the connections.

That’s it – a fresh fan, clean ducts, and better air quality.

When to Call a Professional

If you spot any of these red flags, it’s time to call an expert:

  • Burning smell or sparks from the motor.
  • Repeated tripping of the breaker after a simple fix.
  • Complex ductwork that’s hard to access.
  • Electrical work beyond a simple plug‑in connection (e.g., hard‑wired circuits).

Professionals have the tools to test motor windings, replace sealed bearings, and ensure the vent complies with building codes. Plus, a qualified electrician or ventilation specialist can safely work with high‑voltage wiring.

Regular maintenance goes a long way. Wipe the fan cover every few months, run a short cleaning cycle for the duct, and listen for any change in sound. A well‑kept extractor fan lasts 5‑10 years, so you’ll avoid costly replacements.

Bottom line: Most extractor fan hiccups are DIY‑friendly, but don’t gamble with electricity or a motor that’s clearly damaged. Keep the steps simple, stay safe, and enjoy fresh air without the hassle.
