OEM Carrier Dual Run Capacitor 50+7.5 MFD 370V for Model PH13NR036000AHAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH13NR036000AHAA heat pump condenser. A dual run capacitor serves two motors simultaneously — storing and releasing the electrical charge needed to start and sustain both the compressor and the condenser fan motor during every cycle. When this capacitor weakens or fails, you'll typically notice a loud hum with no compressor start, the condenser fan spinning slowly or not at all, warm air blowing from your vents, or the unit short-cycling shortly after startup. Catching a failing capacitor early prevents far more expensive compressor damage down the road.

• Specs: 50+7.5 MFD (microfarad) | 370V rated | Round case | Factory-matched OEM tolerance | OEM Part Numbers: P291-5073RS, P291-5053RS (dual run) | P281-8806 (start capacitor, sold separately)
• OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances for the PH13NR036000AHAA platform. Generic aftermarket capacitors frequently operate outside ±5% MFD tolerance, placing additional stress on the compressor windings and accelerating wear — especially problematic in heat pump applications that run year-round.
• Install difficulty: 2/5 — Capacitors store a lethal charge even after power is cut. Always shut off the disconnect, then discharge the capacitor using an insulated resistor or discharge tool before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Note the HERM, FAN, and C terminal labels on the capacitor body.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff. Note: P291-5073RS has been superseded by P291-5074R — our team verifies the current active OEM part ships for your unit.
