International Comfort Products PGMD48G0906 Blower Wheel
The primary blower wheel has fins all around it and is traditionally used to generate airflow throughout all the ducts. It is sometimes called a squirrel cage because of the noticeable resemblance to that of a hamster wheel. Whatever name you use, it is a necessary aspect of a heating and cooling system that needs a good amount of airflow.
Warnings that your blower wheel is in dire straights
- You discover quite a bit less air flow as of late
- Rattling noise is heard while the system ramps up
- If a piece of the cage has broken off and it causes a lot of vibration
