OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH13NR03600GAAAA

This factory-matched capacitor kit includes both the P291-5073RS Dual Run Capacitor and the P281-8806 Start Capacitor — the two OEM-specified capacitors for the Carrier PH13NR03600GAAAA 3-ton heat pump condenser. The dual run capacitor continuously supports both the compressor and condenser fan motor during normal operation, while the start capacitor delivers the short, high-torque burst of current needed to kick the compressor into motion on each cooling or heating cycle. When either component degrades, you may experience a humming condenser that never starts, a compressor that trips on thermal overload, or a system that short-cycles within the first few minutes of operation — all classic capacitor failure signatures.

• Specs — Dual Run (P291-5073RS): 50 + 7.5 MFD | 370V rated | Round case | ±5% factory tolerance | Replaces HC98JA052
• Specs — Start Capacitor (P281-8806): 88–108 MFD | 330V rated | Includes bleed resistor | 2.06" diameter × 4.37" length
• OEM vs Generic: Genuine Carrier OEM capacitors are manufactured to exact factory tolerances. Aftermarket units frequently deviate ±10% MFD, accelerating compressor and fan motor wear and risking premature failure — especially in hard-start conditions common in heat pump applications.
• Install difficulty: 2/5 — Always discharge capacitors before handling — stored voltage can be lethal. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring terminals before disconnecting. The start capacitor includes a bleed resistor; confirm correct terminal orientation before reinstalling.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered as the OEM replacement for Carrier PH13NR03600GAAAA 3-ton R-410A split-system heat pump condensers. Always verify MFD and voltage ratings against your unit's data plate before installation. Have a question about fitment?
