The dual run capacitor stores and releases the electrical charge needed to start and continuously run both the compressor and the condenser fan motor. When this capacitor weakens or fails, symptoms include a loud hum with no motor movement, the system short-cycling within minutes of startup, or the condenser fan spinning slowly or not at all. Replacing it promptly protects your compressor from hard-start damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40+5 MFD (microfarad) | 440V rated | Round case | ±6% capacitance tolerance | 50\/60 Hz | AFC 10,000 | Castor oil protected | No PCB | UL approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline OEM capacitor manufactured to factory specifications. Generic units often carry ±10% MFD tolerance, which accelerates compressor and motor wear.
