OEM Carrier Dual Run & Start Capacitor Kit for Model PH11JA018000AAAA

This OEM capacitor kit contains both the factory-specified dual run capacitor (P291-2553RS) and start capacitor (P281-1896S) for the Carrier PH11JA018000AAAA heat pump condensing unit. The dual run capacitor stores and releases the electrical charge that keeps both the compressor and condenser fan motor running during normal operation, while the start capacitor delivers the high-torque burst of current needed to get the compressor spinning on each cooling or heating cycle. When either fails, you'll typically experience symptoms such as a humming compressor that won't start, a system that trips the breaker immediately, or a unit that short-cycles within the first few minutes of operation.

• Dual Run Capacitor Specs (P291-2553RS): 25+5 MFD (microfarad) | 370 VAC rated | Round case | Replaces HC98JA026, HC98CA026, P291-2553R | Factory-matched ±3% tolerance
• Start Capacitor Specs (P281-1896S): 189–227 MFD | 330 VAC rated | Round case | 50/60 Hz | Replaces 092A189B330CE7X, P2811896S
• OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances, ensuring precise MFD ratings and voltage stability. Generic aftermarket capacitors frequently exhibit ±10% MFD drift, accelerating compressor wear, shortening motor life, and voiding equipment warranties.
• Install Difficulty: 2/5 — Always discharge capacitors fully before handling — they store lethal voltage even when power is off. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring before disconnecting. Replace one capacitor at a time to avoid wiring errors.
• Warranty: 1-year OEM factory warranty on both capacitors. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PH11JA018000AAAA heat pump. Always verify the MFD rating and voltage stamped on your existing capacitors against the data plate inside your unit before installing.
