Lennox G40DF-36A-070 Blower Wheel
The blower wheel is like a squirrel cage that is attached to the main blower motor, which is used to produce a steady airflow through a dwelling. It is sometimes called a squirrel cage because of the striking resemblance to that of an oversized hamster exercise wheel. However you decide to name it, it is a necessary contraption of a heating and cooling system that needs proper air circulation.
How can I tell if my main blower wheel is dying?
- If any one of the fins has broken off and it seems out of balance
- You discover less than normal flow of air
- Grinding noise is heard as the HVAC system starts up
