International Comfort Products NTG3100GFA1 Blower Wheel
The primary blower wheel usually has fins all around it and it is traditionally used to produce an airflow throughout all the ductwork of a home. It is sometimes referred to as a squirrel cage because of the obvious semblance of an oversized hamster running wheel. Regardless of what you call it, it is still a crucial piece of equipment of a heating and cooling system that needs proper air circulation.
Signals that your blower wheel is failing
- You discover less than normal air flow
- If any of the fins has been smashed and does not spin right
- Scraping sound is heard as the HVAC system starts up
