Diagnosed failed dual-run capacitor on 3-ton Ruud heat pump causing compressor hard-start issues and intermittent condenser fan operation. Capacitor tested at 32μF/5μF (rated 45μF/7.5μF). Also found contactor with severely pitted contacts causing voltage drop. Replaced both components and installed surge protector to prevent future electrical issues. Measured superheat at 13°F and subcooling at 10°F after repair—both within spec. Also performed amperage test on compressor (RLA 19.2A vs nameplate 19.8A) indicating healthy compressor despite capacitor failure. System now operating efficiently.
