Background
Since our townhouses were built in 2003, an increasing number of residents have reported excess moisture accumulation in bathrooms, leading to issues such as mildew and water damage. The attached image illustrates a bathroom fan obstructed by dust due to insufficient cleaning on a regular basis.
Please note that maintenance of bathroom fans is the responsibility of individual residents, while maintenance of the exhaust ducting from the ceiling-mounted fan to the rooftop vent falls under the strata’s obligations.
Troubleshooting
Here are some common troubleshooting tips for bathroom exhaust fans:
- Noisy Operation: Check for loose fan blades or a faulty motor.
Tighten the blades or replace the motor as needed. - Lack of Airflow: Inspect the fan blades for dust or debris accumulation.
Clean the blades and ensure there are no obstructions blocking the airflow. - Moisture Accumulation: Check the fan’s housing for cracks or gaps.
Seal any openings to prevent moisture from entering.
Bathroom Fan Maintenance
Regular annual maintenance of bathroom exhaust fans is crucial for their optimal performance and longevity
Here's a step-by-step procedure to ensure your fan operates efficiently:
- Turn Off Power: Always turn off the power to the fan at the circuit breaker before starting maintenance.
- Remove Fan Cover: Unscrew or unsqueeze the fan cover to access the fan blades and motor.
- Clean Fan Blades: Use a soft brush or cloth to remove dust and debris from the fan blades. For stubborn dirt, a mild detergent solution can be used.
- Clean Fan Housing: Use a vacuum cleaner to remove loose dust and debris from the fan housing and motor. Wipe down the housing and motor with a damp cloth to remove any remaining dirt or grime.
- Inspect Ducting: Check the ducting connections for air exhausting to the outdoors at the duct termination.
- Reassemble and Power On: Reattach the fan cover, power on the fan, and ensure it operates smoothly.
By following these steps, you can maintain your bathroom exhaust fan effectively, preventing moisture-related issues and ensuring a healthy indoor environment.
