Lennox G40UH-48C-135 Blower Wheel
The primary blower wheel usually has fins all around it and it is spun around by a motor to provide air circulation to a house. Some people call it a squirrel cage due to the understandable likeness of a rather large hamster wheel. Regardless of what you call it, it is still a crucial piece of equipment that is necessary for suitable airflow.
What warnings should I watch out for to know if my main blower wheel is almost dead?
- A strange noise is audible while the system ramps up
- If a piece of the cage has been smashed and it wobbles when spinning
- You find a lot less than usual airflow coming out of the system
