Most people don’t pay much attention to their bath fans until they turn them on. However, they play an essential role in bathroom functionality and comfort. These fans help keep the room properly ventilated and eliminate excess moisture and humidity. Without them, your bathroom would be susceptible to mold, mildew, and structural damage. But many wonder why they are so noisy, and if something is wrong if they are abnormally loud. While some noise is to be expected, there are signs that indicate your bathroom fan may need a repair.

Reasons Why Your Bath Fans Are Loud

1. Blockage in the Vent

One of the most common reasons you may be experiencing an increase in your fan’s noise is that there is a foreign object stuck inside the vent. Because bath fans have continuous airflow, it’s not uncommon for random items such as a wrapper or piece of paper to get trapped in the vent. There also might be a heavy buildup of lint and dirt. Check if you can see any items that may be causing the noise. If not, the problem may be more serious.

2. Improper Sealing

If bath fans aren’t properly sealed to the ceiling, it can create bothersome noises. It’s important that the fan shape matches the cutout in the ceiling. If the blower wheel that draws from the attic insulation is off-balance, it reduces airflow and makes for a noisy environment.

3. Failing Motor

Bath fans require regular oiling to function properly. Going too long without oil will elicit a scratchy noise or low hum from the motor that will worsen over time. If you know the motor has recently been oiled and the noise is still present, it may indicate that the motor is broken. In this case, call a professional for a repair or replacement.
