A single run capacitor maintains a continuous phase-shifted current to keep a single motor — typically the blower or condenser fan — running efficiently after startup. When this capacitor degrades or fails, you'll notice symptoms such as a humming motor that won't spin, sluggish startup, intermittent shutoffs, or a complete loss of airflow. Replacing it promptly prevents cascading damage to the motor windings.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | OEM part number P291-1503 | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±5% tolerance for precision motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor, manufactured to exact factory tolerances.
