💡 Technician Notes

• A failing run capacitor often causes humming, slow spin-up, or intermittent airflow.

• Inspect for bulges, oil seepage, or terminal corrosion before replacement.

• Always match microfarad and voltage ratings to the original unit to avoid motor stress.

• Dual snap-in terminals speed installation and minimize service time.

• Pair with start capacitor 1497-6881 for a complete electrical refresh kit.
