The dual run capacitor provides the electrical start and run boost for both the compressor and the condenser fan motor simultaneously. When this capacitor begins to fail or fails entirely, you'll commonly notice symptoms such as a loud humming sound with no compressor or fan starting, the system short-cycling within the first few minutes of operation, or a complete failure of the outdoor unit to energize at all. Replacing this part promptly protects your compressor from damaging hard-start conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 35+5 MFD (microfarad) | 370V rated | Round dual-section case | Factory-matched ±3% tolerance for precise motor performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM capacitor built to Payne's exact factory specifications.
