OEM Carrier Dual Run Capacitor 55+7.5 MFD 370V for Model PH13NR042000ACAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH13NR042000ACAA heat pump condenser. Part number P291-5573RS (also serviced by successor P291-5574RS), this round capacitor stores and releases the precise electrical charge required to start and sustain both the compressor and condenser fan motor simultaneously. Common failure symptoms include a loud hum with no motor movement, intermittent short-cycling, a tripped breaker, or a system that runs briefly then shuts down. A failed dual run capacitor is one of the most frequent — and most field-replaceable — causes of a no-cool call in summer heat.

• Specs: 55+7.5 MFD (microfarad) | 370V rated | Round case | ±6% factory tolerance | 50/60 Hz | No-PCB, castor oil-protected | AFC: 10,000 | RoHS compliant
• OEM vs Generic: This OEM Totaline/Carrier capacitor is manufactured to exact factory tolerances. Generic capacitors often carry ±10% MFD variance, placing added stress on the compressor windings and shortening equipment life — especially critical for heat pump compressors that run year-round.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use a 20kΩ resistor or insulated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Match MFD ratings exactly; voltage rating must be equal to or greater than original.
• Warranty & Shipping: 1-year OEM factory warranty. Ships same business day from our warehouse. Free ground shipping on qualifying orders.

Compatibility: Designed for the Carrier PH13NR042000ACAA heat pump condenser. This unit also carries companion start capacitor P281-8806 (88–108 MFD, 330V) — consider replacing both capacitors together during a service call to restore full system reliability and avoid a repeat trip. Verify MFD and voltage ratings on your unit's data plate before ordering. Our team is available to confirm fitment before you buy.
