OEM Carrier Single Run Capacitor for Model PY1PPB036090ABAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1PPB036090ABAA packaged heat pump unit. 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.

• Specs: 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: P291-0403 and P291-1503
• OEM vs Generic: 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.
• Install Difficulty: 2/5 — 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.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM local time ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY1PPB036090ABAA packaged heat pump system. 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.
