GE AZ75H09DACM1 Blower Wheel
The main blower wheel is usually finned and is used in order to generate airflow throughout all the ducts. It is sometimes called a squirrel cage because of its remarkable semblance of a rather large hamster wheel. However you decide to name it, it is a very vital aspect of a heating and cooling system that needs proper airflow.
Subtle cues of a weakening blower wheel assembly
- If a part of the cage has been wrecked and looks unbalanced when it spins
- You discover a lot less than usual air coming from the blower
- Scraping sound heard as the system ramps up
