The start capacitor delivers a powerful electrical boost to the compressor motor at startup, enabling it to overcome initial inertia and reach operating speed quickly. When this component fails, you'll typically experience hard-starting, the compressor humming but failing to turn over, nuisance tripped breakers, or a complete no-start condition — all signs of a capacitor that can no longer deliver the required starting surge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched microfarad (MFD) rating | Factory-specified voltage rating | Designed for compressor start-assist duty | Built to exact Carrier factory tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM capacitor is manufactured to Carrier's precise specifications, ensuring correct MFD tolerance (±3%) and rated voltage.
