International Comfort Products PA5542AKA1 Blower Wheel
The main blower wheel is a finned wheel that is traditionally used to provide forced air through an entire home. Once in a while it is also called a squirrel cage because of its similarity of an oversized wheel a hamster might run on. Regardless of what you call it, it is a necessary aspect of any HVAC system that needs a good amount of airflow.
How can I tell if my main blower wheel is in need of a replacement?
- You discover less than normal air going through the vents
- If any one of the fins has been damaged and it causes a lot of vibration
- Grinding noise is noticed when the system ramps up
