The dual run capacitor provides the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When this component fails, you'll typically hear a low hum with no motor movement, notice the system short-cycling, or find the outdoor fan spinning slowly or not at all — leaving your home without cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 45+5 MFD (microfarad) | 370V rated | Round case | ±6% tolerance | 50\/60 Hz | AFC: 10,000 | Castor oil protected | No PCBs | UL approved current interrupter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM-spec capacitor meets exact factory tolerance requirements.
