The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and discharging the electrical energy needed to start and sustain each motor through the full operating cycle. When this capacitor weakens or fails, the most common symptoms are a loud humming or buzzing with no compressor start, a condenser fan that spins slowly or not at all, the system short-cycling within minutes of startup, or a tripped breaker from motor overload. Left unaddressed, a failed capacitor will rapidly overheat and permanently damage the compressor — making timely replacement critical.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 70+5 MFD (microfarad) | 370\/440V dual-rated | Round case | Factory ±3% MFD tolerance | OEM part number P291-7053RS (superseded by P291-7054R)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact Carrier factory tolerances, ensuring proper motor starting torque and run efficiency. Generic aftermarket units often carry a ±10% MFD tolerance, which accelerates motor bearing wear and can shorten compressor life significantly over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling any terminals (use an insulated screwdriver across each terminal pair). Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. The entire swap typically takes under 20 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.

Note that OEM part P291-7053RS has been superseded by updated part number P291-7054R — both are functionally identical at 70+5 MFD 370\/440V. Always verify the MFD rating and voltage stamped on your existing capacitor's label before ordering. Our parts specialists are available to confirm fitment prior to purchase — reach out before you order if you have any questions.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62640473211251,"sku":"CARRIE-PY3GNA048115AA-CAPACITOR-P291-7053RS","price":32.95,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62640473244019,"sku":"CARRIE-PY3GNA048115AA-CAPACITOR-P291-7053RS-GEN","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-P291-7053RS_2210ab38-e8d3-4418-87a9-e9c3eabb7563.jpg?v=1775028805","url":"https:\/\/nationalhvacparts.com\/products\/carrier-py3gna048115aa-capacitor-xaecaq","provider":"National HVAC Parts","version":"1.0","type":"link"}
