Carrier 380B Blower Wheel
The blower wheel is the primary device that is used to produce a steady airflow through all the ducts. Once in a while it is also called a squirrel cage because of its alikeness of a rather large hamster wheel. No matter what you call it, it is still a crucial contraption that is required for proper air pressure within the ductwork.
What symptoms are present when the blower wheel probably is dying?
- Rattling noise is heard as the motor begins to turn
- If any of the fins has been wrecked and it seems out of balance
- You find a lot less air flow as of late
