Trane PTHD120 Blower Wheel
The primary blower wheel has fins all around it and is traditionally used to provide forced air through a home. You may also see it named a squirrel cage due to the slight similarity of a hamster wheel. Whatever you want to call it, it is a necessary aspect of any heating or cooling systems that requires a good amount of airflow.
Simple warnings that your blower wheel assembly is dying?
- If one of the fins has been smashed and it seems out of balance
- You discover lower than normal air flow as of late
- Grinding noise is noticed as your blower begins
