International Comfort Products NDN3050FBA1 Blower Wheel
The main blower wheel is a finned wheel that is spun around by a motor to generate airflow throughout a dwelling. It is also called a squirrel cage because of the striking resemblance of an oversized wheel a hamster might run on. Whatever name you use, it is definitely an important aspect of any heating or cooling systems that requires a good amount of airflow.
Main clues blower wheel assembly is in need of replacing
- If any of the fins has been damaged and it spins lopsided
- You notice quite a bit less air going through the ducts
- Grinding sound heard as the motor begins to turn
