Lennox CB28UH-024 Blower Wheel
The primary blower wheel is a finned wheel that is traditionally used to provide forced air through all the ducts. It is also called a squirrel cage due to its semblance of a rather large hamster wheel. Regardless of what you call it, it is still a crucial piece of equipment of any system that needs proper airflow.
What are the clues to watch out for to know my main blower wheel is dying?
- A vibration can be heard when the system ramps up
- If a piece of the cage has broken off and it seems out of balance
- You detect a lot less air flow as of late
