OEM Carrier Single Run Capacitor 370V (P291-0403 / P291-1003 / P291-1503) for Model PY1PEB048115AAAA

These OEM single run capacitors are the factory-specified replacements for the Carrier PY1PEB048115AAAA packaged gas/electric unit. 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.

• Part Numbers & Specs: 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
• OEM vs Generic: 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.
• Install Difficulty: 2/5 — 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.
• Warranty & Shipping: 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.
