Dryer Vent In Attic Fan Noise

This was observed on numerous days following the installation.

Dryer vent in attic fan noise.

I can feel some water around the metal wrapping of the vent where there is an opening. If the fan blades are imbalanced or bent they can hit against one another or against other parts of the fan. Lift up the edges of the surrounding roof shingles so you can see the edges of the vent. The problem with attics the attic is usually colder than the rest of the house during the winter and that can create a problem for a dryer vent.

The attic fan tends to makes a humming noise when it has a few blades and is running at a high speed setting. 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. 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. The logic behind these booster fans makes simple sense.

Banging or rattling if you are finding that your vent or the vent pipes start rattling and gurgling every time you start up the dryer you may have one of a number of problems. Blade is made of thin metal sheets in most of the household fans. The most serious problem is the accumulation of lint along the sides of the pipes and at the end. Check for imbalanced or bent blades.

The dryer fan is capable of moving air efficiently x number of feet. Shut off the fan before examining the blades and see if there s a problem or not. And there is no exception with the attic fans as well. Remove the screws holding the vent in place.

Lint in the vent is the prime cause of vent fires. Climb onto the roof and locate the vent that is causing the noise. Due to regular wear and tear these bearings can become worn out or lose their lubrication ability. If the dryer ducting is going to be more than that add a booster fan and the fan can help move the air that much further.

During workdays would leave air conditioner off when leaving in the morning. If so the rotating blade will create some noise and the airflow outcome won t be as expected also. It gets stuck in the fan blades. Remove the current worn out bearings and replace them.

Attic fans also have small ball bearings that help lubricate the fan s movement. This will definitely produce noise while the blades are rotating. Temp 92 f at 5pm. The warm moist air inside the vent tends to.

Temp 84f at 5pm. This can cause the fan to start making constant noise and in some cases even a loud squealing sound. Cut through any sealer that may be present.
