Lennox CB30U-46 Blower Wheel
A blower wheel is like a squirrel cage that is attached to the main blower motor, which is used in order to provide air circulation to a home. You may also see it named a squirrel cage due to the partial semblance of a very large wheel a hamster would run on. Regardless of what you call it, it is a necessary contraption that is needed for suitable airflow.
Major symptoms that your blower wheel probably is dying
- If any one of the fins has been twisted and it causes a lot of vibration
- Rattling noise is audible as your system initiates
- You find a lot less than usual air flow in the house
