The start capacitor provides the short-duration electrical boost the compressor needs to overcome inertia and reach operating speed on each cooling or heating cycle. When this capacitor fails, the compressor struggles to start, draws excessive locked-rotor amperage, and will typically trip on thermal overload — leaving you with a system that hums briefly and then shuts off, or one that won't start at all. Replacing a failed start capacitor promptly also protects your compressor from repeated hard-start stress and premature wear.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 88–108 MFD (microfarad) | 330V rated | 2.06\" diameter × 4.37\" length | Round case with bleed resistor | Factory-matched tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier-sourced capacitor meeting exact factory MFD tolerance.
