Carrier 25HPA524H0030010 Blower Wheel
The main blower wheel is like a squirrel cage that is attached to the main blower motor, which is used in order to produce a steady airflow through all the ductwork of a home. Some people call it a squirrel cage because of its unusual likeness to that of an oversized hamster exercise wheel. Whatever name you use, it is a necessary device of a heating and cooling system that needs proper air pressure within the ductwork.
Easy warnings of a defective main blower wheel
- A scraping sound heard as the blower starts
- If a part of the cage has been smashed and it spins lopsided
- You may sense lower than normal airflow coming out of the system
