Lennox 13ACD-036 Blower Wheel
The primary blower wheel is attached to the blower motor and is spun around by a motor to produce an airflow throughout an entire house. It is also referred to as a squirrel cage because of the striking similarity of a hamster wheel. Whatever you decide to call it, it is a very vital device of any HVAC system that needs a good amount of airflow.
Warnings of a weak blower wheel cage
- If any one of the fins has been dented and it wobbles when spinning
- A vibration is heard as the HVAC system starts up
- You detect less than normal air coming from the blower
