International Comfort Products PHF048K000A Blower Wheel
The main blower wheel usually has fins all around it and it is used as to generate airflow throughout all the ducts. It is also referred to as a squirrel cage due to the understandable alikeness to that of a pet hamster wheel. Whatever you want to call it, it is a necessary device that is required for proper air pressure within the ductwork.
Indications that the main blower wheel will not live much longer
- A rattling sound is noticed as the system begins
- If any of the fins has broken off and does not spin right
- Noticeably less flow of air coming from the blower
