Extractor Fan Help: Repair, Maintenance & When to Call a Pro

If your kitchen or bathroom fan has gone quiet, it's not always a sign you need a whole new unit. Most extractor fan issues can be solved with a few simple steps. In this guide we’ll walk you through the most common problems, easy DIY checks, and the exact point where a qualified gas engineer should step in.

Common Reasons Extractor Fans Stop Working

First, figure out what’s actually stopping the fan. The usual suspects are:

• Power loss. Check the circuit breaker or fuse box. A tripped breaker is often the quickest fix.
• Blocked vent. Grease, dust or lint can clog the duct, causing the motor to overheat and shut down.
• Worn motor bearings. A humming sound followed by silence usually means the motor needs lubrication or replacement.
• Faulty switch or timer. If the fan only works when you manually switch it on, the timer may be dead.
• Loose wiring. Vibration over time can loosen connections, leading to intermittent power.

When you spot one of these, you can often fix it yourself. If the motor is dead or the wiring looks damaged, it’s safer to call a certified engineer.

Simple Maintenance Steps to Keep Your Fan Running

Regular maintenance extends the life of any extractor fan. Set a reminder to do these tasks every 3‑6 months:

1. Turn off power. Always switch off the breaker before you start.
2. Remove and clean the filter. Soak a metal or carbon filter in warm, soapy water, rinse well and let it dry.
3. Vacuum the duct. Use a narrow brush attachment to pull out dust and grease from the vent pipe.
4. Check the fan blades. Wipe them with a damp cloth; any buildup will reduce airflow.
5. Inspect the motor. Look for rattling or excessive heat. A quick spin test can reveal stuck bearings.

After you reassemble, turn the power back on and run the fan for a minute. If it stays quiet or sounds strange, stop and contact a professional.

Remember, an extractor fan that works well saves you from excess moisture, mold and lingering cooking smells. A quick clean now can keep costly repairs at bay later.

Finally, don’t ignore warning signs. Burning smells, sparks, or a fan that runs intermittently are red flags. These issues involve electricity and gas components that should only be handled by a qualified engineer.
