The run capacitor stores and releases electrical energy to sustain steady blower motor operation throughout the heating or cooling cycle. When this capacitor weakens or fails, you'll typically notice the blower motor humming without spinning, the system short-cycling, or a complete loss of airflow — all symptoms that point directly to a failed run capacitor before any other component is blamed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarads) | 370V rated (440V-rated upgrade, P291-0754, also fits) | Oval case form factor | ±5% factory tolerance | Replaces discontinued OEM part # P291-0753\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact Carrier factory tolerances.
