OEM Payne Start Capacitor P281-1766 for Model PA4ANG030000BBAA

This is the factory-specified OEM start capacitor (part number P281-1766) for the Payne PA4ANG030000BBAA air conditioner. A start capacitor provides the high-torque electrical boost required to get the compressor motor spinning at startup. Once the motor reaches operating speed, the start capacitor is switched out of the circuit. When this component fails, you'll typically experience a humming compressor that won't start, repeated tripped breakers, hard-start conditions, or a system that simply won't turn on — even though the thermostat is calling for cooling.

• Specs: OEM start capacitor | Part No. P281-1766 | Factory-matched microfarad and voltage rating | Designed for Payne 2.5-ton split-system condenser applications
• OEM vs Generic: This is a genuine OEM part manufactured to exact factory specifications. Generic start capacitors frequently fall outside acceptable tolerance ranges, placing excessive strain on compressor windings and shortening equipment life significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — stored charge can cause serious injury. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. If unsure, consult a licensed HVAC technician.
• Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Payne PA4ANG030000BBAA split-system air conditioner. The "030" designation identifies this as a 2.5-ton unit. Always verify the microfarad (MFD) rating and voltage on your existing capacitor or unit data plate before ordering to confirm this is the correct replacement. Our fitment specialists are available to verify compatibility before you purchase — same-day shipping means your repair won't wait.
