Lennox CB29M-31 Blower Wheel
The main blower wheel is like a squirrel cage that is attached to the main blower motor, which is used to generate airflow throughout a dwelling. It is also called a squirrel cage due to the partial alikeness of a hamster wheel. No matter what you call it, it is still a crucial aspect that is needed for suitable airflow.
Major indications of a faulty main blower wheel
- Scraping sound is audible when the system ramps up
- You discover quite a bit less air going through the ducts
- If a part of the wheel has been smashed and it spins lopsided
