Lennox G20 Blower Wheel
The primary blower wheel is like a squirrel cage that is attached to the main blower motor, which is used as to produce a steady airflow through a dwelling. Some people call it a squirrel cage due to the similarity of an oversized hamster running wheel. Whatever you want to call it, it is a very vital device of any heating or cooling systems that requires proper air circulation.
Key indicators that my blower wheel assembly is not working properly?
- If a piece of the cage has been bent and does not spin right
- A thumping noise can be heard when the system starts
- You find lowered air coming from the vents
