Lennox XC21-024 Blower Wheel
The primary blower wheel is finned and is spun around by a motor to produce an airflow throughout all the ductwork of a home. It can also be referred to as a squirrel cage due to the understandable similarity to that of an oversized hamster exercise wheel. Regardless of what you call it, it is a very vital contraption that is required for a good amount of airflow.
Signals that the main blower wheel will eventually need to be replaced
- If one of the fins has broken off and it seems out of balance
- Rattling noise heard as the system begins
- You discover lowered airflow lately
