Whirlpool ATR0742RPP0 Blower Wheel
The primary blower wheel is commonly finned and is used in order to provide air circulation to an entire house. Once in a while it is also called a squirrel cage due to the understandable similarity of a rather large hamster wheel. Regardless of what you call it, it is a very vital aspect of any HVAC system that needs proper airflow.
Clues of a weakening blower wheel
- You see lowered air going through the ducts
- If a little piece of a fin has been wrecked and it seems out of balance
- A clanking sound heard as the blower starts to turn
