Trane TTZ048A100A1 Blower Wheel
A blower wheel has fins all around it and is spun around by a motor to produce a steady airflow through all the ducts. It is occasionally called a squirrel cage due to its alikeness of a hamster wheel. Regardless of what you call it, it is a necessary piece of equipment of any system that needs proper air circulation.
What to see if the blower wheel assembly is in need of a replacement?
- If a part of the cage has been dented and it causes a lot of vibration
- You detect lower than normal air coming out of the vents
- A vibration is audible as the HVAC begins
