The dual run capacitor provides continuous electrical support to both the compressor and the condenser fan motor, while the start capacitor delivers the high-torque surge needed to cycle the compressor on under load. When either capacitor degrades or fails, symptoms include a loud hum with no motor movement, the system tripping on thermal overload within minutes of startup, or the compressor failing to start on warm days while the fan continues to spin.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Run Cap Specs:\u003c\/strong\u003e 80+5 MFD (microfarad) | 370V rated | Round case | OEM part P291-8053 (current successor: P291-8054R) | ±5% factory tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Cap Specs:\u003c\/strong\u003e 88-108 MFD | 330V rated | With bleed resistor | OEM part P281-8806 | Cycles off after compressor reaches operating speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact Carrier factory tolerances and undergo 100% electrical testing. Generic aftermarket units commonly run outside rated MFD tolerance, accelerating compressor wear and shortening system life — especially critical on high-demand 5-ton heat pump compressors like the PH12NA060000AAAA.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge capacitors before handling (use a 20,000-ohm resistor or insulated screwdriver across terminals).
