International Comfort Products PGMD42G0608 Blower Wheel
The primary blower wheel has fins all around it and is traditionally used to provide air circulation to all the ducts. It is also named a squirrel cage due to the clear resemblance of an oversized wheel a hamster might run on. No matter what you call it, it is definitely an important device of any heating or cooling systems that requires proper air pressure within the ductwork.
Signals of an unhealthy blower wheel
- If a piece of the cage has broken off and it does not spin correctly
- Vibrating is heard as the motor begins to turn
- You may sense less than usual air going through the ducts
