International Comfort Products VNK125N20A1 Blower Wheel
The main blower wheel is the squirrel cage attached to the blower motor that is spun around by a motor to produce an airflow throughout all the ducts. You may also see it named a squirrel cage because of its remarkable resemblance of a very large wheel a hamster would run on. Whatever you decide to call it, it is definitely an important contraption of a heating and cooling system that needs proper air circulation.
Warnings of a deteriorating main blower wheel
- You detect less than usual air flow as of late
- A vibration can be heard as the blower starts to turn
