International Comfort Products PGAD30D1K4 Blower Wheel
The primary blower wheel is attached to the blower motor and is spun around by a motor to produce an airflow throughout a dwelling. Some people call it a squirrel cage because of the obvious likeness of a very large wheel a hamster would run on. No matter what you call it, it remains a vital contraption of any heating or cooling systems that requires proper airflow.
Major indications that the main blower wheel is going to die
- Grinding sound is heard while the system ramps up
- If any one of the fins has broken off and it seems out of balance
- You see much less flow of air
