What is a Blower Wheel on a Dryer?

A blower wheel is a critical component of a dryer that is responsible for moving hot air through the machine and ultimately drying clothes. Understanding the function of the blower wheel is important for maintaining the efficiency and effectiveness of the dryer. In this article, we will discuss the function of a blower wheel in a dryer, common issues that may arise, and steps to maintain and repair it.

Description of a Dryer Blower Wheel

A blower wheel in a dryer is a spinning fan-like component that is located within the machine’s housing. It is responsible for drawing air into the dryer through the lint filter and heating it before forcing the air through the drum and out of the vent. The blower wheel’s rotation creates the necessary airflow for the dryer to effectively and efficiently dry clothes.

Common Issues with a Dryer Blower Wheel

Buildup of lint or debris on blower wheel

One of the most common issues that arise with a dryer blower wheel is a buildup of lint or debris. When the blower wheel becomes clogged with lint, it may cause a decrease in airflow, making the drying process longer and less effective. This can also lead to overheating and potential damage to other dryer components.

Damage or wear to the blower wheel

Another issue that can occur is damage or wear to the blower wheel itself. This can happen due to normal wear and tear over time, but may also occur due to foreign objects getting caught in the wheel. Damage to the blower wheel can also result in a decrease in airflow, making it difficult for the dryer to operate effectively.

Damage or wear to the blower wheel

Symptoms of a malfunctioning blower wheel can include strange noises, a longer drying time, or an inability to dry clothes completely. If any of these symptoms are present, it may be time to check the blower wheel for any issues.

Maintenance and Repair of a Dryer Blower Wheel

To prevent issues with the blower wheel, regular maintenance is required. This includes cleaning the lint filter after each use, checking the dryer vent for blockages, and periodically inspecting the blower wheel for any buildup or damage.

Cleaning a blower wheel can be done by first unplugging the dryer and removing the front panel to access the wheel. The wheel can be cleaned using a soft brush or cloth to remove any lint or debris. If the blower wheel is damaged or worn, it may need to be replaced.

Repair or replacement of a blower wheel should only be done by a trained professional. Attempting to repair or replace the blower wheel without proper knowledge can lead to further damage to the dryer and potential safety hazards.


The blower wheel in a dryer is a vital component in the drying process. Understanding its function and potential issues can help to maintain the efficiency and effectiveness of the dryer. Regular maintenance and cleaning of the blower wheel can help prevent potential issues, and professional repair or replacement should be sought if any problems arise. By properly maintaining the dryer’s blower wheel, users can ensure that their dryer is operating efficiently and effectively.
