Internal Fan Motor Assembly
The 'whir' sound is the acoustic result of metal-on-metal friction occurring within the motor's internal ball bearing races. Over time, the factory-sealed lubricant can oxidize or migrate, leading to localized heating and microscopic surface pitting on the bearings. Replacing the motor assembly restores the silent operation of the centrifugal fan by providing a fresh, balanced bearing set.
