OEM Carrier Dual Run & Start Capacitor Kit — P291-3554RS + P281-8806 for Model PH10JA036000AGAA

This factory-matched OEM capacitor kit contains both the dual run capacitor (P291-3554RS) and the start capacitor (P281-8806) required for the Carrier PH10JA036000AGAA heat pump system. The dual run capacitor continuously powers both the compressor and the condenser fan motor, while the start capacitor delivers the high-torque surge needed to kick the compressor into motion on each cycle. When either capacitor fails, you'll experience symptoms ranging from an audible hum with no motor movement, a system that trips the breaker, or a unit that starts briefly and then shuts down within seconds. Replacing both together is the industry-recommended approach — if one has failed, the other is under equal stress and near end of life.

• Dual Run Capacitor (P291-3554RS) Specs: 35+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | Non-PCB dielectric fluid | UL-approved pressure-sensitive current interrupter
• Start Capacitor (P281-8806) Specs: 88–108 MFD | 330V rated | Round case | Includes bleed resistor | Factory-spec direct drop-in replacement
• OEM vs Generic: OEM Carrier/Totaline capacitors are held to tighter manufacturing tolerances than aftermarket alternatives. Generic units often deviate ±10% MFD from rating, increasing thermal stress on compressor windings and shortening equipment life. This kit is genuine factory-authorized.
• Install difficulty: 2/5 — Always discharge the capacitor before handling — it retains lethal voltage after shutdown. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The start capacitor bleed resistor must be reinstalled on the new unit. If in doubt, call a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty on both capacitors. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the exact OEM replacement kit for Carrier model PH10JA036000AGAA. Verify your unit's data plate MFD and voltage ratings before ordering. Our fitment team is available to confirm compatibility — reach out before you buy for total peace of mind. In stock and ships today.
