Heat Controller VMH12SC-1 Blower Wheel
A blower wheel usually has fins all around it and it is used as to generate airflow throughout all the ducts. Once in a while it is also called a squirrel cage because of the obvious semblance of a rather large hamster wheel. Whatever you decide to call it, it is a very vital contraption of a heating and cooling system that needs proper air pressure within the ductwork.
Major symptoms your blower wheel is going out
- If one of the fins has been bent and looks unbalanced when it spins
- You discover a lot less than usual air flow as of late
- Scraping sound is noticed when the system ramps up
