🛠️ HVAC Depot Pro Tip:

When replacing this motor, always verify that the amp draw is within the motor’s nameplate value after installation to ensure optimal performance. Additionally, since this is an "Air Over" motor, ensure that the airflow from the fan it is driving is sufficient to keep the motor housing cool during operation.
