International Comfort Products N9MPD075F12A2 Blower Wheel
The primary blower wheel usually has fins all around it and it is spun around by a motor to produce a steady airflow through an entire home. Once in a while it is also called a squirrel cage because of the obvious likeness of a very large wheel a hamster would run on. Whatever you want to call it, it is definitely an important aspect of any HVAC system that needs suitable airflow.
What are the clues to watch out for to know my main blower wheel is on its last leg?
- A vibration can be heard when the system starts
- You detect a lot less airflow overall
- If a piece of the cage has broken off and it causes a lot of vibration
