Clean the fan blades
You should clean your fan at least once a month. Remember to remove the front grille if you are cleaning a wall-mounted fan.
You can quickly remove thin layers of dust by cleaning the fan blades with a vacuum cleaner and brush attachment.
For thicker layers of dust, wipe the top and bottom of each fan blade with a damp cloth. Avoid shaking or bending the fan blades excessively to prevent damage.
Do not use ammonia or bleach-based cleaners or any harsh cleaners to clean the fan, as this may wear away its surface finish and cause warping to the fan blades.
Tighten all screws
Loose screws can result in noisy or shaky fans.
The screws on the fan may loosen over time due to the fan’s vibrations. Simply tighten any screws with a screwdriver, particularly those on the fan, ceiling plate, and light fixture, if any.
Noise from ceiling or wall-mounted fans can disturb your neighbours, especially low-humming or intermittent sounds.
For most cases, you can resolve the humming noise by lubricating the fan with light machine oil.
If the humming noise persist after lubricating the fan, you may need to consult a reliable fan supplier/ installer to install an insulation pad (such as a fan rubber) to the base of the fan or to repair the fan.
Intermittent noise may be caused by loose fan blades or screws. You can address this by tightening the screws.
If the intermittent noise persist, it could be caused by the deterioration of the rubber holding the fan. You will need to consult a reliable fan supplier/ installer to replace it.
