OEM Payne Start Capacitor P281-8806 for Model PA13NR018000ACAA

This is the factory OEM start capacitor (part number P281-8806) for the Payne PA13NR018000ACAA single-stage split-system air conditioner. The start capacitor delivers the high-voltage surge needed to kick the compressor motor into rotation at startup. Without a functioning start capacitor, the compressor struggles to turn over, drawing excess current — you'll typically hear a loud hum, see the breaker trip, or notice the outdoor unit failing to start entirely while the indoor blower continues running.

• Specs: OEM-matched capacitance and voltage rating | Factory-specified tolerance | Designed for single-phase compressor start duty | Direct replacement for Payne part number P281-8806
• OEM vs Generic: This OEM unit is manufactured to exact Payne factory specifications. Generic start capacitors frequently ship with wider capacitance tolerances (±10% or more), which can cause hard-starting, premature compressor wear, and shortened equipment life — particularly in smaller 1.5-ton systems where electrical margins are tighter.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections prior to removal. Reconnect terminals firmly to avoid arcing.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered specifically for the Payne PA13NR018000ACAA 1.5-ton R-22 split-system condenser. Always verify your existing capacitor's MFD and voltage ratings against your unit's data plate before ordering. Not sure if this part fits your system?
