International Comfort Products PA9524AKA1 Blower Wheel
The blower wheel is attached to the blower motor and is used to produce an airflow throughout all the ducts. Some people call it a squirrel cage due to its semblance of an oversized hamster running wheel. Regardless of what you call it, it is still a crucial piece of equipment that is essential for suitable airflow.
Major signs that your blower wheel probably is failing
- A scraping sound is audible as the motor ramps up
- If any of the fins has been malformed and seems unbalanced when it turns
- You may sense quite a bit less air going through the vents
