Carrier 38YSA042 Blower Wheel
The primary blower wheel is usually finned and is traditionally used to provide air circulation to an entire house. Once in a while it is also called a squirrel cage due to a funny resemblance to that of a wheel that a pet hamster may use for exercise. No matter what you call it, it is definitely an important aspect that is necessary for proper air pressure within the ductwork.
Hints that your blower wheel will not live much longer
- If any of the fins has been malformed and it seems out of balance
- You notice less than normal airflow coming out of the system
- A weird sound is noticed as the motor begins to turn
