OEM Payne Dual Run & Start Capacitor Replacement for Model PA12NA03600GAAAA

This OEM-specified capacitor set includes both the dual run capacitor (P291-5073RS) and the start capacitor (P281-8806) for the Payne PA12NA03600GAAAA split-system air conditioner. Together, these capacitors store and release the electrical charge necessary to start and sustain the compressor and condenser fan motor during each cooling cycle. When either component fails, symptoms typically include a loud humming from the condenser cabinet, a compressor that fails to start, or a system that trips the breaker or short-cycles within minutes of startup. Replacing both units at the same time is strongly recommended — if one has failed, the other is likely stressed and near end of life.

• Specs: P291-5073RS — Dual Run Capacitor, round case, 370V/440V rated, factory-matched MFD tolerance ±3% | P281-8806 — Start Capacitor, high-capacitance boost for hard-start conditions, matched to Payne factory specifications
• OEM vs Generic: OEM capacitors are manufactured to Payne's exact tolerance specifications. Aftermarket units commonly ship at ±10% MFD variance, which accelerates wear on the compressor windings and condenser fan motor bearings, shortening overall system life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty on both capacitors. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Payne PA12NA03600GAAAA 3-ton single-stage split-system condenser. Always verify MFD rating and voltage against your unit's data plate before completing your order. Our fitment specialists are available to confirm compatibility before you buy — no guesswork required.
