Lennox G40UH-24A-045 Blower Wheel
The primary blower wheel has fins for maximum air force and is used to provide forced air through a dwelling. Once in a while it is also called a squirrel cage due to the understandable similarity of an oversized wheel a hamster might run on. Whatever you want to call it, it remains a vital part that is required for suitable airflow.
General warnings poorly running blower wheel assembly
- If one of the fins has been malformed and it causes a lot of vibration
- You find lower than normal airflow overall
- A strange noise is audible as the HVAC system starts up
