Carrier 48XPN060130300 Blower Wheel
A blower wheel is usually finned and is spun around by a motor to produce a steady airflow through an entire house. It can also be called a squirrel cage because of its similarity of an oversized hamster running wheel. Whatever you decide to call it, it is a very vital contraption that is essential for proper air pressure within the ductwork.
Key signs of a bad main blower wheel
- If one of the fins has been dented and seems unbalanced when it turns
- You find quite a bit less air going through the ducts
- A thumping noise can be heard when the system starts
