The PY1PEB048115AAAA uses three individual oval single run capacitors — one for the compressor motor, one for the condenser fan motor, and one for the indoor blower motor — rather than a combined dual run unit. When any one of these capacitors fails, you'll typically notice a humming sound with no motor movement, a motor that starts slowly and then trips, or an outright no-cooling\/no-airflow condition. Replacing the failed capacitor with the correct OEM-rated unit restores proper torque, motor efficiency, and compressor longevity.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers \u0026amp; Specs:\u003c\/strong\u003e P291-0403 — 4 MFD \/ 370V Oval Single | P291-1003 — 10 MFD \/ 370V Oval Single | P291-1503 — 15 MFD \/ 370V Oval Single | All oval case, 50\/60 Hz, UL-recognized, RoHS compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e These are genuine Totaline\/Carrier OEM capacitors manufactured to ±5% MFD tolerance and tested to 60,000 service hours. Generic capacitors often run at ±10% tolerance, accelerating motor wear and reducing compressor life — especially critical on a 4-ton packaged unit running in high-ambient conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always disconnect and lock out power before servicing. Discharge the capacitor terminals using an insulated screwdriver or bleed resistor before touching leads. Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. Match the MFD rating exactly — never substitute a different value.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e 1-year OEM factory warranty against defects. Ships same business day from our warehouse. Verify the MFD and voltage rating on your unit's wiring diagram or data plate before ordering — the PY1PEB048115AAAA uses all three capacitors listed; order the specific rating for the motor circuit you are replacing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits Carrier model \u003cstrong\u003ePY1PEB048115AAAA\u003c\/strong\u003e packaged gas\/electric unit (4-ton, 115 MBH gas heat).
