Carrier 42S Blower Wheel
A blower wheel is attached to the blower motor and is used to provide forced air through all the ducts. It is also named a squirrel cage due to the understandable alikeness to that of a hamster wheel. Whatever you want to call it, it is a very vital aspect of any heating or cooling systems that requires proper air circulation.
Cues of a barely functioning main blower wheel
- A scraping sound can be heard as the blower begins
- If a piece of the cage has been twisted and seems unbalanced when it turns
- You may sense lowered air flow as of late
