Lennox G40DF-48C-090 Blower Wheel
The primary blower wheel is like a squirrel cage that is attached to the main blower motor, which is used to produce an airflow throughout an entire home. It can also be called a squirrel cage because of the noticeable alikeness of a rather large hamster wheel. No matter what you call it, it is definitely an important aspect of any HVAC system that needs suitable airflow.
Major symptoms to watch for in a bad main blower wheel
- If a piece of the cage has been malformed and it spins lopsided
- A rattling sound heard while system starts
- Suddenly less flow of air through the vents
