LG LMU240CE Blower Wheel
The main blower wheel has fins all around it and is spun around by a motor to provide forced air through a home. It is sometimes called a squirrel cage due to its semblance to that of an oversized hamster exercise wheel. Whatever you decide to call it, it is a necessary aspect of any system that needs suitable airflow.
Signs that the main blower wheel will eventually need to be replaced
- If one of the fins has broken off and does not spin right
- You notice less airflow through the ducts
- A rattling sound is audible as the system begins
