OEM Carrier Dual Run Capacitor & Start Capacitor for Model PH13NR04200GACAA

This OEM-matched capacitor set — dual run capacitor P291-5573RS and start capacitor P281-8806 — is the factory-specified replacement for the Carrier PH13NR04200GACAA 4-ton single-stage R-410A heat pump condenser. The dual run capacitor stores and releases the electrical energy needed to start and sustain both the compressor and condenser fan motor simultaneously. The start capacitor provides the extra torque boost required during compressor start-up under high-load or high-ambient-temperature conditions. When either fails, symptoms include a loud hum with no motor start, compressor short-cycling, tripped breakers, or the system failing to cool or heat altogether.

• Specs — Dual Run (P291-5573RS): Factory-rated MFD and voltage matched to Carrier PH13NR04200GACAA | 440V round case | ±5% OEM tolerance | Replaces compressor + fan motor capacitor in a single unit
• Specs — Start Capacitor (P281-8806): High-microfarad short-duty start boost capacitor | Rated for intermittent use | Paired with hard-start relay for maximum compressor longevity
• OEM vs Generic: OEM capacitors are manufactured to exact factory MFD tolerances (±5%). Generic aftermarket units frequently run ±10–15% out of spec, placing unnecessary stress on the compressor windings and shortening equipment life — especially critical on R-410A systems operating at higher pressures.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling terminals (use an insulated resistor or discharge tool — never a screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The start capacitor mounts in-line with the compressor start terminal; confirm relay compatibility before installation.
• Warranty & Shipping: 1-year OEM factory warranty coverage. Ships same business day from our stocked warehouse — order by 3 PM local time for next-day delivery eligibility.

Compatibility: Designed specifically for Carrier PH13NR04200GACAA 4-ton single-stage R-410A heat pump condensers. Always verify MFD rating, voltage, and terminal configuration against your unit's data plate before installing. Not sure it fits?
