Whirlpool ATR0945SPP0 Blower Wheel
The main blower wheel is usually finned and is used to produce a steady airflow through all the ducts. You may also see it named a squirrel cage due to the clear alikeness of a rather large hamster wheel. Whatever you want to call it, it is a very vital aspect of any system that needs proper air pressure within the ductwork.
Signs of an inadequate blower wheel cage
- A rattling sound can be heard as your blower begins
- If a part of the cage has been dented and does not spin right
- You notice less airflow through the ducts
