OEM Carrier Dual Run Capacitor 35+5 MFD 440V for Model PH10JA036000AAAA

This is the factory-specified OEM dual run capacitor (part number P291-3554RS) for the Carrier PH10JA036000AAAA packaged heat pump unit. The dual run capacitor stores and releases the electrical charge required to start and sustain both the compressor and the condenser fan motor during every cooling and heating cycle. When this capacitor weakens or fails, the most common symptoms are a loud humming from the cabinet with no compressor start, the condenser fan spinning slowly or not at all, or the unit tripping on thermal overload after struggling to start. A companion start capacitor (P281-8806, 88–108 MFD 330V) is also used on this model to give the compressor an additional torque boost at startup — consider inspecting or replacing it at the same time.

• Specs (P291-3554RS): 35+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | Non-PCB dielectric fluid | UL-approved pressure-sensitive interrupter | Replaces HC98KA030, HC98CA035, HC98CA036, P291-3553RS
• OEM vs Generic: This OEM Carrier/Totaline capacitor is factory-matched to ±6% MFD tolerance. Aftermarket generics commonly run ±10%, which causes the compressor and fan motor to draw excess current, accelerating winding wear and shortening equipment life.
• Install difficulty: 2/5 — Always discharge the capacitor before removing terminals (use an insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Total job time: 15–20 minutes.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH10JA036000AAAA packaged heat pump unit. Always verify MFD rating and voltage on your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — contact us today.
