International Comfort Products PGAA42E1K1 Blower Wheel
A blower wheel is finned and is spun around by a motor to produce an airflow throughout an entire house. It is occasionally called a squirrel cage because of its unusual resemblance to that of a wheel that a pet hamster may use for exercise. Whatever you decide to call it, it is definitely an important contraption that is required for a good amount of airflow.
What are the signs that the main blower wheel has a need to be replaced?
- If a little piece of a fin has broken off and looks unbalanced when it spins
- Scraping sound heard while the system ramps up
- You discover a lot less air coming out of the vents
