The dual run capacitor (OEM part \u003cstrong\u003eP291-4053\u003c\/strong\u003e) simultaneously supports both the compressor and the condenser fan motor in a single round capacitor, while the single run capacitor (\u003cstrong\u003eP291-1503\u003c\/strong\u003e) is used when only one motor requires support. When either capacitor fails, common symptoms include a loud humming noise with no motor movement, the condenser fan spinning slowly or not at all, the compressor short-cycling, or the unit tripping the breaker shortly after startup. Replacing a faulty capacitor is one of the most cost-effective repairs in residential HVAC service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual run — P291-4053 | Single run — P291-1503 | 370V rated | Round case design | Factory-matched ±3% MFD tolerance | Rated for R-410A systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Payne capacitors are manufactured to exact factory tolerances, ensuring proper motor starting torque and runtime efficiency.
