The start capacitor delivers the high-voltage electrical surge needed to kick the compressor into motion at startup. Once the compressor reaches operating speed, the start capacitor is cycled out of the circuit by the start relay. When this capacitor fails, you'll typically notice the compressor humming but failing to start, the system tripping on high-pressure lockout, or the unit drawing excessive amperage before shutting down on thermal overload. Left unaddressed, a failed start capacitor will eventually damage the compressor itself.\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 | Includes integrated bleed resistor for safe discharge | Factory tolerance ±5%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM component sourced through the Totaline factory parts program. OEM capacitors are manufactured to exact MFD tolerance and voltage rating for your unit. Generic off-brand capacitors often deviate ±10–15% MFD, which can cause repeated compressor hard-start stress and premature failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — The bleed resistor discharges this capacitor automatically, but always verify discharge with a multimeter before handling. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Swap terminals one at a time to avoid miswiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
