OEM Carrier Dual Run Capacitor 35+5 MFD 370V for Model PH10JA03600GAGAA

This is the factory-specified OEM dual run capacitor (part number P291-3554RS) for the Carrier PH10JA03600GAGAA packaged heat pump unit. The dual run capacitor provides the electrical start-and-run boost required by both the compressor and the condenser fan motor simultaneously. When this capacitor fails, symptoms include a loud humming noise with no motor movement, the system short-cycling within seconds of startup, a warm supply despite the system running, or complete failure to start. Left unaddressed, a weak or failed capacitor places severe strain on the compressor — the most expensive component in your system.

• Specs (P291-3554RS): 35+5 MFD (microfarad) | 370V rated | Round dual run case | Factory-matched ±3% tolerance | Replaces OEM part P291-3554RS
• Companion Start Capacitor (P281-8806): This unit also uses a separate 88–108 MFD 330V start capacitor (P281-8806) to assist compressor startup. If your compressor is struggling or failing to start, consider replacing both capacitors together for a complete restoration.
• OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances (±3% MFD). Generic aftermarket units frequently run ±10% or wider, accelerating motor and compressor wear and shortening overall system life.
• Install difficulty: 2/5 — Always discharge the capacitor fully before removing any terminals — stored voltage can be lethal. Tools needed: 1/4" nut driver, needle-nose pliers, insulated screwdriver, multimeter. Photograph all wiring connections before disconnecting. If unsure, contact a licensed HVAC technician.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
