OEM Carrier Dual Run & Start Capacitor Kit 80/5 MFD 370V + 88-108 MFD 330V for Model PH12NA060000AAAA

This factory-matched OEM capacitor kit contains both the dual run capacitor (P291-8053 / P291-8054R, 80/5 MFD 370V) and the start capacitor (P281-8806, 88-108 MFD 330V) specified for the Carrier PH12NA060000AAAA heat pump. The dual run capacitor provides continuous electrical support to both the compressor and the condenser fan motor, while the start capacitor delivers the high-torque surge needed to cycle the compressor on under load. When either capacitor degrades or fails, symptoms include a loud hum with no motor movement, the system tripping on thermal overload within minutes of startup, or the compressor failing to start on warm days while the fan continues to spin.

• Dual Run Cap Specs: 80+5 MFD (microfarad) | 370V rated | Round case | OEM part P291-8053 (current successor: P291-8054R) | ±5% factory tolerance
• Start Cap Specs: 88-108 MFD | 330V rated | With bleed resistor | OEM part P281-8806 | Cycles off after compressor reaches operating speed
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances and undergo 100% electrical testing. Generic aftermarket units commonly run outside rated MFD tolerance, accelerating compressor wear and shortening system life — especially critical on high-demand 5-ton heat pump compressors like the PH12NA060000AAAA.
• Install difficulty: 2/5 — Always discharge capacitors before handling (use a 20,000-ohm resistor or insulated screwdriver across terminals). Photograph all wiring before disconnecting. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter set to capacitance mode. Replace both capacitors together for maximum reliability and value.
• Warranty: 1-year OEM factory warranty on both capacitors. Ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PH12NA060000AAAA 5-ton heat pump. Verify MFD ratings and voltage on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — in stock and ships today.
