The run capacitor maintains a continuous phase-shifted current to keep the compressor or condenser fan motor running efficiently after startup. A failing run capacitor is one of the most common causes of HVAC service calls — symptoms include a loud hum with no motor movement, intermittent short-cycling, tripped breakers, or a compressor that starts briefly then shuts down on thermal overload.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Round or oval case depending on variant | 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 OEM capacitor is manufactured to Carrier's exact ±3% MFD tolerance specification. Aftermarket generics frequently ship at ±10% tolerance, which increases motor operating temperature, accelerates winding wear, and can void equipment warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before touching terminals (use a 20kΩ resistor or insulated discharge tool). Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wire connections before removal. Swap wires one at a time to avoid miswiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.

Always verify the MFD rating and voltage printed on your existing capacitor or unit data plate before ordering — two part numbers (P291-0403 and P291-1503) cover variant configurations within this model. Not sure which one you need? Our HVAC parts specialists verify fitment before you order — contact us before checkout.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62640799613299,"sku":"CARRIE-PY1PPB036090ABAA-CAPACITOR-P291-0403","price":40.95,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62640799646067,"sku":"CARRIE-PY1PPB036090ABAA-CAPACITOR-P291-0403-GEN","price":35.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-P291-0403_9726de46-6dab-4dd8-9b63-1f6fb98fcbaf.jpg?v=1775039538","url":"https:\/\/nationalhvacparts.com\/products\/carrier-py1ppb036090abaa-capacitor-42kxl1","provider":"National HVAC Parts","version":"1.0","type":"link"}
