ceiling fan motor noise

ceiling fan motor noise

Attic power vent warning:

Fan blades are extremely sharp! When doing any type of maintenance work around it, make sure that power supply to the motor has been turned off! Most of those vents are controlled by a heat or humidity sensing switch, and can become active/cause injury while you’re performing cleaning.

Humming, muffled noise coming from above the ceiling during the summer is most likely an attic power vent, working hard to pull out hot air from under the roof (attic power vent should be placed close to the roof ridge – top, or installed as a gable vent).

The most common installations include adjustable thermostat and in some cases humidistat, which activates an attic power vent motor accordingly with your preferences (once set, it operates automatically responding to temperature or/and humidity changes).

There are also some devices preset by the manufacturer (usually between 85F – 100F), and attic power vents with no sensor at all, controlled by on/off switch mounted in various location (usually close to the attic entrance).

For the attic power vent to serve its purpose properly, and save instead of wasting your money, certain requirements have to be met:

There must be other, adequate number (or more likely square footage area) of ventilation ports installed in lower section of the roof.

Those ports are called:

• soffit vents, if your house roof has an overhang, which extends beyond the house exterior wall
• or gable vents – located at the attic area, commonly on the exterior wall where the two planes of a sloping roof join, forming a triangle

There’s a possibility, that type of your roof allows only for installation of vents on its surface – good examples are hip roofs on many of the Chicago style Georgian type homes, which have no overhang/soffits.

In such case, if the attic power vent has been installed in upper section of the roof, passive vents should be placed not less than 1/3 of the distance between the roof bottom edge and top (ridge). Hip / ridge vent system can be also installed, or vented drip edge mounted along the roof edges.

For the attic power vent to perform efficiently, the attic floor, and all penetrations between the attic and living area of your house should be properly insulated and sealed.

Any gaps, holes, and lack or inadequate number of attic vents will cause attic power vent to create a vacuum, and remove AC cooled air from the house. In some properties, there’s an open duct (or two) between the attic and utility room, which provides combustion air for gas burning appliances – it must remain open on both sides.

• Make sure that the attic power vent, or its opening is protected with wire mesh / screen. Vents are usually equipped with wire mesh that wraps exterior of the fan blades housing, and prevents rodents from accessing attic area. If that screen becomes damaged and you decide to install one from the attic side, be prepared to clean it often – the birds often build nests inside the fan, especially during the cold season.

Also, some of the larger animals are strong enough to penetrate this obstacle, in the process damaging fan blades. Therefore, it’s a good idea to examine your attic periodically – be careful, most attics have no flooring installed, and walking on framing is difficult / if possible, examine fan condition from attic access point.

Before installing a new attic power vent in your house attic area, make sure you properly calculate square footage area – vent calculator. If installed fan is too small, it will have to operate much longer, to move the same amount of air through the attic.

• Adjusting thermostat too low might cause fan to run constantly during hot summer – try to set the temperature dial to a 100 -110 degrees Fahrenheit.

The fan should start automatically as soon as the attic temperature rises above the preset setting, and cuts off when the attic is cooled down to approximately 10% below the thermostat setting.

Go Green and try low voltage, solar battery operated power vent – saves money on installation, very quiet, but approximately 3 times as expensive, as a regular attic power vent.

Why does my ceiling fan begin to whine?

I turn on the ceiling fan when I go to bed anytime between 10pm and midnight and some nights, not all, it begins to whine about 3 or 4 in the morning. I can turn it off and turn it back on or move it around and nothing changes, I just have to turn it off for the remainder of the night. When I turn it back on after waking it no longer makes noise.

I have already checked the balance of the blades and they are good. The blades are clean as well. The sound sounds like maybe the motor? Any ideas?

the fault lies in one of th two bearings which is goten loose with the use and starts making whining sound after some use on speed you try to use the same fan on a slower speed …..and you will find that either the sound will not come at all or even if it comes it will be after a longer time interval …..sometimes simple oiling and greasing also may help
