International Comfort Products PGMD30G0604 Blower Wheel
A blower wheel is the squirrel cage attached to the blower motor that is used in order to produce a steady airflow through all the ducts. It is occasionally called a squirrel cage due to the semblance of a rather large hamster wheel. Regardless of what you call it, it is a necessary part of a heating and cooling system that needs a good amount of airflow.
What warnings are present when my main blower wheel needs replacing?
- Much less flow of air making its way through the vents
- A rattling sound heard as the system ramps up
- If any part of the wheel has broken off and it does not spin correctly
