Shut off the fan before examining the blades and see if there s a problem or not. The attic fan tends to makes a humming noise when it has a few blades and is running at a high speed setting. Due to regular wear and tear these bearings can become worn out or lose their lubrication ability. I have my fan vented out through the roof but near the inside of the roof in my attic the vent leaks a bit and condensation gets on the wood and a bit down in the insulation around where the vent goes out.

If so the rotating blade will create some noise and the airflow outcome won t be as expected also. Lint in the vent is the prime cause of vent fires. In order to get rid of the hum you need to either operate the fan at a low speed or replace the fan with a new one that has more blades.

Attic fans also have small ball bearings that help lubricate the fan s movement. Due to excessive pressure or sudden strikes these blades might get bent or damaged. Temp 92 f at 5pm. I can feel some water around the metal wrapping of the vent where there is an opening.

The logic behind these booster fans makes simple sense. Cut through any sealer that may be present. Remove the current worn out bearings and replace them.
