Carrier 38YRA042 Blower Wheel
A blower wheel is commonly finned and is traditionally used to provide air circulation to a house. It is sometimes referred to as a squirrel cage because of the noticeable semblance to that of a wheel that a pet hamster may use for exercise. Whatever name you use, it remains a vital device of a heating and cooling system that needs a good amount of airflow.
Clues to watch for to know your blower wheel is failing
- You may sense a lot less than usual flow of air
- A scraping sound can be heard while system starts
- If any of the fins has been malformed and it wobbles when spinning
