Run capacitors provide the continuous phase-shifted current that keeps motors running efficiently after startup. When either capacitor weakens or fails, you may notice the compressor or fan motor humming but not spinning, the unit short-cycling within minutes of startup, higher-than-normal energy consumption, or complete failure to cool. Replacing both at the same service call is best practice — a weakened companion capacitor dramatically shortens the life of a new one.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — P291-0403:\u003c\/strong\u003e 4 MFD (microfarad) | 370V | Oval case | Carrier Totaline factory part | ±5% capacitance tolerance | RoHS compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — P291-1503:\u003c\/strong\u003e 15 MFD (microfarad) | 370V | Oval case | Carrier Totaline factory part | UL approved with patented pressure-sensitive interrupter | Proven to 60,000 service hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Carrier Totaline OEM capacitors are 100% electrically tested at the factory and built to United Technologies reliability standards.
