Common extractor fan problems & how to fix them

Top tips for enhancing extractor fan performance

At Go Assist, we recognise the importance of extractor fans in maintaining a healthy and comfortable home environment. These essential appliances play a crucial role in ventilating kitchens and bathrooms, preventing moisture build-up, and improving indoor air quality. However, like any appliance, extractor fans can encounter various issues over time. Understanding these common problems and knowing how to address them can help you keep your extractor fan running smoothly and efficiently.

1. Fan not working at all

One of the most frustrating issues homeowners face with extractor fans is when they fail to work altogether. This problem can stem from several causes, including electrical issues, motor failure, or a faulty switch. If your extractor fan isn’t operating, here are steps you can take to diagnose and potentially resolve the issue:

• Check the power supply: Ensure that the extractor fan is receiving power. Sometimes, a tripped circuit breaker or a blown fuse could be the culprit.
• Inspect wiring: Examine the wiring connections to see if there are any loose or damaged wires. Secure connections or replace damaged wires as necessary.
• Test the switch: Verify that the switch controlling the extractor fan is functioning correctly. Sometimes, switches can wear out over time and may need replacement.

If these steps do not resolve the issue, it’s advisable to seek professional help from a qualified technician who can diagnose the problem accurately and perform any necessary repairs.

2. Low extraction rate

Another common issue with extractor fans is a reduced extraction rate, meaning the fan isn’t effectively removing odours, steam, or airborne particles from the room. This can be caused by:

• Clogged vents: Over time, dust, grease, and debris can accumulate in the vents, restricting airflow. Regular cleaning of the vents can help maintain optimal extraction performance.
• Blocked fan blades: Inspect the fan blades for any obstructions such as dirt or debris. Clean the blades carefully to ensure they can rotate freely and extract air efficiently.
• Inadequate fan size: If the extractor fan is undersized for the room or area it’s intended to ventilate, it may struggle to provide adequate extraction. Consider upgrading to a more powerful extractor fan if necessary.

Ensuring proper ventilation and airflow in your home is crucial not only for comfort but also for maintaining indoor air quality and preventing mold and mildew growth.

3. Excessive noise

Extractor fans that produce excessive noise can be disruptive and indicate underlying issues such as:

• Loose parts: Vibrations caused by loose screws or mounting brackets can amplify noise. Tighten any loose parts to reduce vibrations and noise.
• Worn bearings: Over time, the bearings in the fan motor can wear out, causing loud noises during operation. Lubricating or replacing worn bearings can help restore quiet operation.
• Debris in the fan: Dirt or debris lodged in the fan blades can create noise as they rotate. Cleaning the fan blades thoroughly can eliminate the source of the noise.

Addressing these issues promptly not only improves the acoustic environment of your home but also prolongs the lifespan of your extractor fan.

4. Fan running continuously 

If your extractor fan runs continuously, it could be due to:

• Faulty timer: Extractor fans with timers may malfunction, causing them to operate non-stop. Check the timer settings and replace the timer if necessary.
• Incorrect installation: Improper installation, particularly with wiring, can cause the fan to run continuously. Ensure that the fan was installed according to manufacturer specifications.
• Wiring issues: Faulty wiring or a short circuit can also cause the fan to run continuously. Inspect the wiring and address any issues to prevent further damage.

Continuous operation not only wastes energy but can also lead to premature wear and tear of the extractor fan components. Correcting the underlying cause will help restore normal operation and efficiency.

5. Condensation and mould around fan

Lastly, extractor fans that do not effectively remove moisture from the air can contribute to condensation and mould growth around the fan and in the surrounding area. This issue can be addressed by:

• Improving ventilation: Ensure that the extractor fan is properly sized for the room and that it operates efficiently to remove excess moisture.
• Regular use: Use the extractor fan regularly, especially during activities that generate steam or humidity (e.g., cooking, showering).
• Maintenance: Keep the fan and its surrounding area clean and free from mould or mildew. Regularly inspect and clean the fan to prevent buildup that could impede airflow.

Maintaining a dry and mould-free environment not only promotes a healthier indoor environment but also extends the lifespan of your extractor fan.

Proper maintenance and timely repairs are essential for ensuring that your extractor fan operates efficiently and effectively. If you encounter persistent issues with your extractor fan and require professional assistance, don’t hesitate to book a repair online or call 0333 733 1234 today!
