    The problem

    During an annual furnace tune-up, the run capacitor on the blower motor was found to require replacement. This component is essential for proper airflow in the heating system.

    Our solution

    We replaced the run capacitor on the PSC blower motor. This included a capacitance test and airflow verification. We also installed a dual run capacitor 55/5 MFD at 370VAC and the related mounting hardware.

    The result

    With the new capacitor installed, we verified its operation and confirmed proper airflow through the system.
