Whirlpool ATE0743SPP0 Blower Wheel
The blower wheel is like a squirrel cage that is attached to the main blower motor, which is used to produce an airflow throughout a home. Some people call it a squirrel cage because of the noticeable similarity to that of a wheel that a pet hamster may use for exercise. Whatever you want to call it, it remains a vital part of a heating and cooling system that needs a good amount of airflow.
Major signs that the main blower wheel will die soon
- A scraping sound is audible when the system ramps up
- You may sense quite a bit less air coming from the blower
- If any of the fins has been malformed and it causes a lot of vibration
