Lennox G40DF-36B-090 Blower Wheel
A blower wheel is attached to the blower motor and is used to produce a steady airflow through all the ductwork of a home. It is occasionally called a squirrel cage because of the noticeable resemblance of an oversized hamster running wheel. Whatever you want to call it, it is definitely an important device of any heating or cooling systems that requires proper air circulation.
Major symptoms of a weakening blower wheel
- If a piece of the cage has been dented and it does not spin correctly
- Noticeably less flow of air making its way through the vents
- A rattling sound can be heard while system starts
