Mitsubishi MSZ-FD09NA Blower Wheel
A blower wheel usually has fins all around it and it is spun around by a motor to produce an airflow throughout a home. Some people call it a squirrel cage due to the semblance of a rather large hamster wheel. However you decide to name it, it remains a vital piece of equipment of a heating and cooling system that needs a good amount of airflow.
What are the signs that the main blower wheel is not working right?
- If a little piece of a fin has been damaged and looks unbalanced when it spins
- Scraping sound heard as the blower starts
- You discover less than usual flow of air
