OEM Carrier Dual Run & Start Capacitor Kit (P291-3553RS + P281-8806) for Model PH13NR018000ACAA

This factory-matched OEM capacitor kit includes both the dual run capacitor (P291-3553RS) and the start capacitor (P281-8806) specified for the Carrier PH13NR018000ACAA split-system heat pump. The dual run capacitor continuously supports both the compressor and condenser fan motor during operation, while the start capacitor provides a powerful extra torque boost to reliably kick the compressor into motion on every cycle. When either capacitor fails, symptoms range from a humming unit that won't start, to a compressor that trips the breaker, short-cycles within minutes, or fails to cool or heat entirely — leaving you with a fully non-functional system.

• Dual Run Capacitor Specs (P291-3553RS): 35+5 MFD (microfarad) | 370V rated | Round style | Terminals: HERM–C–FAN | Factory ±3% tolerance | Manufactured by GE/Genteq for Carrier
• Start Capacitor Specs (P281-8806): 88–108 MFD | 330V rated | With bleed resistor | 2.06" diameter | Cycles on the compressor at startup to prevent hard-start burnout
• OEM vs Generic: These are genuine Carrier-sourced OEM capacitors built to exact factory tolerances. Generic aftermarket alternatives commonly run ±10% MFD drift, which accelerates compressor wear, increases amp draw, and can void equipment warranties. Replacing both capacitors together as a kit is best practice and maximizes system longevity.
• Install Difficulty: 2/5 — Always discharge capacitors before handling — they store lethal voltage even with power off. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Start cap typically mounts near the contactor; run cap mounts in the outdoor unit's control section.
• Warranty: 1-year OEM factory warranty on both capacitors. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: This kit is engineered for the Carrier PH13NR018000ACAA heat pump condenser. Always verify the MFD and voltage ratings on your unit's data plate before ordering — using a capacitor with incorrect MFD will damage the compressor.
