The run capacitor maintains the continuous phase-shifted current needed to keep the motor running at rated torque and efficiency. When this capacitor weakens or fails, you'll notice symptoms such as a humming condenser with no motor start, intermittent short-cycling, reduced airflow, compressor overheating, or a tripped high-pressure limit. Replacing it promptly prevents costly secondary damage to the motor windings or compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case | 50\/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | ±5% factory tolerance | Multiple electrical terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier\/Totaline OEM part, sourced through authorized distribution channels.
