International Comfort Products NTG3075HFA1 Blower Wheel
The main blower wheel is commonly finned and is used to produce a steady airflow through a home. Some people call it a squirrel cage because of the obvious alikeness of a rather large hamster wheel. However you decide to name it, it is still a crucial device that is necessary for proper air pressure within the ductwork.
Symptoms that your blower wheel should need replacing
- If any one of the fins has been dented and looks unbalanced when it spins
- You notice quite a bit less air flow
- Grinding sound can be heard as the blower starts
