A single run capacitor provides the continuous phase-shifted current needed to keep the blower motor running efficiently after startup. When this capacitor weakens or fails, common symptoms include a humming motor that won't spin, intermittent blower operation, the system tripping on thermal overload, or reduced airflow that causes the coil to freeze. Replacing this component promptly prevents secondary damage to the blower motor itself.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched MFD rating | 370V rated | Designed for single-motor fan coil blower application | Factory ±5% tolerance for reliable, long-term motor performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor built to exact factory tolerances.
