The start capacitor provides the brief but powerful electrical boost needed to get the compressor spinning at startup. Without a functioning start capacitor, the compressor will hum, draw locked-rotor amperage, and trip its thermal overload — or simply fail to start at all. A failed start capacitor is one of the most common causes of a heat pump that clicks on but never cools or heats.\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\" height | Includes integrated bleed resistor | Round case design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is manufactured to Carrier's exact MFD tolerance (±5%), ensuring correct starting torque. Generic start capacitors often carry ±10–20% tolerances, placing additional stress on the compressor windings and shortening system life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Discharge capacitor fully before handling — a charged start capacitor can deliver a dangerous shock.
