The dual run capacitor stores and releases the electrical charge needed to start and continuously run both the compressor and condenser fan motor. When this capacitor weakens or fails, you'll notice symptoms like a humming unit that won't start, the system short-cycling off within seconds, or a condenser fan spinning sluggishly or not at all. Left unaddressed, a failing capacitor forces the compressor to draw locked-rotor amperage, dramatically shortening its life. A secondary single run capacitor (part number \u003cstrong\u003eP291-1503\u003c\/strong\u003e) is also available for applications where individual run support is needed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | 50\/60 Hz | AFC: 10,000 | Castor oil protected | No PCB | RoHS compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor meeting exact factory tolerances. Generic aftermarket units often drift ±10% MFD or more, accelerating wear on both the compressor and fan motor and voiding equipment warranties. Note: Carrier sources capacitors from certified third-party manufacturers — labeling will reflect the capacitor maker, not Carrier, which is completely normal for OEM parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Capacitors store a lethal charge even after power is cut. Always discharge the capacitor before handling using an insulated resistor or discharge tool. Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Typical job time: 15–30 minutes for a confident DIYer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e 1-year OEM manufacturer's warranty against defects.
