International Comfort Products NDN3100KFA1 Blower Wheel
The main blower wheel usually has fins all around it and it is used to produce a steady airflow through all the ductwork of a home. Some people call it a squirrel cage due to the understandable similarity to that of an oversized hamster exercise wheel. Regardless of what you call it, it is definitely an important aspect that is needed for proper airflow.
Major symptoms of a weak blower wheel cage
- You notice a lowered airflow through the vents
- A rattling sound is heard while system starts
- If a piece of the cage has been twisted and does not spin right
