OEM Carrier Dual Run Capacitor P291-4573RS & Start Capacitor P281-8806 for Model PH13NR03000GAFAA

This factory-matched OEM capacitor set — comprising the P291-4573RS Dual Run Capacitor and the P281-8806 Start Capacitor — is the manufacturer-specified replacement for the Carrier PH13NR03000GAFAA split-system heat pump condenser. The dual run capacitor continuously powers both the compressor and the condenser fan motor, while the start capacitor delivers the extra torque burst needed to bring the compressor up to operating speed under load. When either component degrades, you'll typically experience symptoms such as a humming condenser that won't start, a compressor that short-cycles after a few minutes of operation, a condenser fan that spins slowly or not at all, or hard-start trips on the circuit breaker.

• OEM Part Numbers: P291-4573RS (Dual Run Capacitor) | P281-8806 (Start Capacitor) — factory-direct components engineered to exact Carrier tolerances for the PH13NR03000GAFAA platform.
• OEM vs. Generic: OEM capacitors are manufactured to ±5% MFD tolerance as required by Carrier. Generic alternatives commonly run ±10–15%, increasing stress on the compressor windings and condenser fan motor bearings, shortening system life and potentially voiding equipment warranties.
• Install Difficulty: 2/5 — Always disconnect and lock out power before servicing. Capacitors store a lethal charge even with power off — discharge all terminals with an insulated resistor before handling. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting. Most technicians complete this repair in under 30 minutes.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up and running fast.

Compatibility: Engineered specifically for the Carrier PH13NR03000GAFAA heat pump condenser. Always verify MFD, voltage rating, and terminal configuration against your unit's data plate before ordering. Not sure if this fits your system?
