Lennox G40DF-36A-045 Blower Wheel
The main blower wheel is attached to the blower motor and is spun around by a motor to provide air circulation to all the ductwork of a home. Once in a while it is also called a squirrel cage due to a funny alikeness of an oversized hamster running wheel. Regardless of what you call it, it is still a crucial aspect of any system that needs proper airflow.
Some clues that your blower wheel probably will not live much longer
- If any part of the wheel has broken off and it seems out of balance
- You find less than usual air going through the ducts
- A strange noise is audible when the system starts
