Lennox G40DF-24A-045X Blower Wheel
The primary blower wheel is a finned wheel that is spun around by a motor to provide air circulation to a home. It is sometimes referred to as a squirrel cage due to a funny similarity of a rather large hamster wheel. Regardless of what you call it, it is still a crucial piece of equipment that is necessary for proper air circulation.
Key signs of a laboring main blower wheel
- A thumping noise is audible as the HVAC system starts up
- If any one of the fins has been smashed and seems unbalanced when it turns
- Suddenly less flow of air through the ducts
