OEM Carrier Dual Run & Start Capacitor for Model HA1CJX060000AAAA

This OEM-matched capacitor set includes both the dual run capacitor (P291-5554RS) and start capacitor (P281-8806) factory-specified for the Carrier HA1CJX060000AAAA 5-ton condensing unit. The dual run capacitor continuously supports both the compressor and condenser fan motor during operation, while the start capacitor delivers the high-torque burst needed to get the compressor spinning under load. When either component fails, symptoms include a loud hum with no motor movement, repeated tripping of the breaker, a compressor that starts briefly then shuts off, or a condenser fan that refuses to spin. Replacing both at once is industry best practice — if one has failed, the other is typically near end of life.

• Specs: P291-5554RS — Dual Run Capacitor, 440V rated, round case, ±5% MFD factory tolerance | P281-8806 — Start Capacitor, 330V rated, designed for hard-start assist on 5-ton compressor loads
• OEM vs Generic: OEM capacitors are wound to exact factory MFD tolerances, protecting compressor windings and fan motor bearings from voltage stress. Generic replacements commonly run ±10% MFD deviation, which shortens compressor life and can void equipment warranties.
• Install Difficulty: 2/5 — Capacitors store lethal charge even after power is cut. Always discharge using an insulated resistor before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before removal.
• Warranty & Shipping: 1-year OEM factory warranty on both capacitors. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier HA1CJX060000AAAA 5-ton single-stage condensing unit. Always verify MFD and voltage ratings on your unit's data plate before installation.
