OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH10JA030000AAAA

This OEM-matched capacitor set — comprising the P291-3553RS Dual Run Capacitor and the P281-8806 Start Capacitor — is the factory-specified replacement for the Carrier PH10JA030000AAAA heat pump system. The dual run capacitor stores and delivers the electrical charge required to start and sustain both the compressor and condenser fan motor during every cycle. The start capacitor provides an additional boost of starting torque to get the compressor spinning under load. When either component degrades, symptoms include a distinct humming with no motor movement, the system tripping on thermal overload, compressor short-cycling within minutes of startup, or a complete failure to energize.

• Included Parts: P291-3553RS Dual Run Capacitor (compressor + fan) | P281-8806 Start Capacitor (compressor starting boost) | Both factory-matched to Carrier PH10JA030000AAAA specifications
• OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerance (±3%), ensuring proper motor starting torque and run efficiency. Generic aftermarket units commonly ship at ±10% tolerance, accelerating compressor wear and risking premature motor failure.
• Install Difficulty: 3/5 — Always disconnect power at the breaker and discharge the capacitor before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode), camera or phone to photograph wiring before disconnection. The start capacitor typically mounts with a bleed resistor — confirm resistor condition before reinstalling.
• Warranty & Shipping: 1-year OEM factory warranty on both components. In stock — ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH10JA030000AAAA heat pump. Always verify your unit's data plate for exact MFD ratings and voltage before ordering. Our technical team is available to confirm fitment — reach out before you buy if you have any questions.
