International Comfort Products PGME Blower Wheel
The main blower wheel is usually finned and is used to produce an airflow throughout a house. It is also called a squirrel cage due to the slight similarity of a very large wheel a hamster would run on. Whatever you decide to call it, it remains a vital contraption of a heating and cooling system that needs proper air pressure within the ductwork.
Simple indications of a failing blower wheel assembly
- Scraping sound is audible as the blower starts to turn
- If any part of the wheel has been wrecked and looks unbalanced when it spins
- You find much less air going through the ducts
