LG LMAN120HNS Blower Wheel
A blower wheel is commonly finned and is used to produce an airflow throughout an entire house. Some people call it a squirrel cage due to the resemblance of a large hamster wheel. Regardless of what you call it, it is definitely an important device that is needed for proper air pressure within the ductwork.
Subtle cues to watch for in a failing blower wheel assembly
- You discover less than usual airflow coming out of the system
- A scraping sound is audible as the blower begins
- If a part of the cage has been dented and it causes a lot of vibration
