Whirlpool ATR0943CPP0 Blower Wheel
A blower wheel is attached to the blower motor and is spun around by a motor to provide air circulation to an entire home. Some people call it a squirrel cage due to the slight alikeness of a very large wheel a hamster would run on. Regardless of what you call it, it is a very vital part of any heating or cooling systems that requires a good amount of airflow.
Clues to watch for to know that the main blower wheel will soon need to be replaced
- Scraping sound heard when the system ramps up
- If one of the fins has been malformed and it causes a lot of vibration
- You may sense quite a bit less air flow as of late
