International Comfort Products PGMD48G1354 Blower Wheel
The primary blower wheel has fins all around it and is spun around by a motor to generate airflow throughout a dwelling. It is sometimes referred to as a squirrel cage because of its remarkable alikeness of an oversized hamster running wheel. No matter what you call it, it remains a vital part that is essential for proper airflow.
Key signs to watch for in a bad blower wheel cage
- A thumping noise can be heard as the HVAC begins
- Lowered airflow through the vents
- If one of the fins has been twisted and does not spin right
