Trane PTHD090 Blower Wheel
The primary blower wheel is a finned wheel that is used to provide air circulation to all the ducts. It is also named a squirrel cage due to the slight semblance to that of a pet hamster wheel. Whatever you want to call it, it is a very vital contraption that is required for proper airflow.
How do you know when your Trane blower wheel needs replacing?
- If any part of the wheel has broken off and it does not spin correctly
- You detect quite a bit less air coming from the vents
- Vibrating can be heard when the system ramps up
