💡 Technician Notes

• Humming, sluggish spin-up or uneven airflow often signal a weakening run capacitor

• Always inspect for bulges, oil seepage or corrosion before installation

• Confirm microfarad rating matches the original unit to avoid motor stress

• Dual snap-in posts speed service calls and cut downtime

• Pair with a fresh start capacitor (e.g., 1497-6881) or a new blower motor for a full electrical refresh

Can also be used with the WSX-7 Hard start capacitor
