Carrier 40MFC018 Blower Wheel
The primary blower wheel is usually finned and is traditionally used to produce a steady airflow through all the ducts. It is occasionally called a squirrel cage due to its resemblance of a large hamster wheel. Whatever you want to call it, it is still a very necessary contraption of any HVAC system that needs proper air circulation.
What are the signs that the blower wheel assembly is in need of replacing?
- If a little piece of a fin has been dented and it spins lopsided
- Scraping sound is heard as the motor begins to turn
- You discover less than normal air coming from the vents
