The run capacitor maintains a continuous phase-shifted current to keep the compressor or fan motor spinning at rated efficiency. When the capacitor degrades or fails, you'll notice symptoms like a humming compressor that won't start, intermittent short-cycling, a hot outdoor unit that shuts down quickly, or a complete no-cool condition — even with the thermostat calling for cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Matches OEM MFD and voltage rating for PY3PPA042060AA | Factory-matched ±5% tolerance | Replaces OEM part numbers \u003cstrong\u003eP291-0403\u003c\/strong\u003e and \u003cstrong\u003eP291-1503\u003c\/strong\u003e\n\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 specifications.
