OEM Payne Dual Run & Start Capacitor Kit for Model PA12NA018000AAAA

This OEM capacitor kit includes both the P291-4053RS Dual Run Capacitor and the P281-8806 Start Capacitor — the factory-specified replacements for the Payne PA12NA018000AAAA single-zone mini-split system. Capacitors store and release the electrical charge required to start and run both the compressor and fan motor. A failing capacitor is one of the most common causes of mini-split failure: symptoms include a loud hum with no motor movement, the system short-cycling within the first few minutes of operation, or the unit refusing to start at all despite the thermostat calling for cooling.

• OEM Part Numbers: P291-4053RS (Dual Run Capacitor) and P281-8806 (Start Capacitor) — factory-matched tolerances for the Payne PA12NA018000AAAA platform, maintaining ±3% MFD accuracy versus the ±10% common on aftermarket units
• OEM vs Generic: Factory OEM capacitors are wound to exact voltage and microfarad specifications for this unit. Off-brand substitutes running outside tolerance cause accelerated compressor wear, increased amp draw, and shortened system life — especially critical on inverter-driven mini-split compressors
• Install Difficulty: 3/5 — Always discharge capacitors before handling any terminals (stored charge can be lethal). Tools needed: insulated screwdrivers, needle-nose pliers, multimeter with capacitance mode, and a discharge resistor or insulated jumper. Photograph all wiring before disconnecting. If unsure, consult a licensed HVAC technician
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse — get your system back up and running fast

Compatibility: This kit is matched to the Payne PA12NA018000AAAA mini-split system. Always verify capacitor MFD and voltage ratings against your unit's data plate before installing. Our fitment team is available to confirm compatibility before you order — don't guess on a safety-critical component.
