OEM Carrier Dual Run & Start Capacitor Kit for Model PH12NA030000ABAA

This OEM capacitor kit includes both the dual run capacitor (P291-4573RS) and the start capacitor (P281-8806) — the two factory-specified capacitors for the Carrier PH12NA030000ABAA packaged heat pump unit. The dual run capacitor sustains continuous operation of both the compressor and condenser fan motor, while the start capacitor delivers the extra torque burst needed to kick the compressor into motion on each cycle. When either fails, symptoms range from audible humming with no motor spin, to hard start attempts, to the unit short-cycling off on thermal overload within minutes of startup.

• Dual Run Capacitor Specs (P291-4573RS): 45+7.5 MFD (microfarad) | 370V rated | Round case | ±5% factory tolerance | Replaces HC98JA047 and GE 97F9969
• Start Capacitor Specs (P281-8806): 88–108 MFD | 330V rated | Includes bleed resistor | Factory Totaline/Carrier specification for PH12NA030000ABAA
• OEM vs Generic: OEM capacitors are built to Carrier's exact tolerance specifications and reliability-tested to 60,000 service hours. Generic aftermarket units frequently run at ±10% MFD tolerance, accelerating compressor wear and increasing hard-start failures over time.
• Install Difficulty: 2/5 — Always discharge both capacitors fully before touching terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
• Warranty: 1-year OEM factory warranty on both capacitors. Ships same business day from our warehouse.

Compatibility: This kit is engineered specifically for the Carrier PH12NA030000ABAA packaged heat pump. Always confirm your unit's data plate MFD and voltage ratings before ordering. Bryant and Payne variants sharing the same capacitor spec may also be compatible — contact our fitment team to verify before purchasing. In stock and ready to ship today.
