OEM Carrier Dual Run & Start Capacitor Set for Model HC1CJX048000ABAA

This OEM-matched capacitor set includes both the dual run capacitor (P291-6073RS) and the start capacitor (P281-8806) factory-specified for the Carrier HC1CJX048000ABAA 4-ton condensing unit. The dual run capacitor sustains continuous operation of both the compressor and condenser fan motor, while the start capacitor delivers the high-voltage boost needed to get the compressor spinning on each cycle. When either component fails, symptoms include a loud humming with no motor movement, a compressor that trips the breaker immediately, a condenser fan that won't spin, or a system that short-cycles within the first few minutes of operation — all of which result in lost cooling and accelerated compressor wear if left unaddressed.

• Specs: P291-6073RS — Dual Run Capacitor, 370V/440V rated, round case, ±5% MFD factory tolerance | P281-8806 — Start Capacitor, high-capacitance boost design; verify MFD ratings on your unit's data plate before ordering to confirm exact values
• OEM vs Generic: OEM capacitors are wound and tested to Carrier's exact factory tolerance, ensuring proper motor start torque and run efficiency. Aftermarket units often carry a wide ±10% MFD variance that increases compressor heat, shortens motor life, and can void equipment warranties.
• Install Difficulty: 2/5 — Always shut off power at the disconnect and at the breaker panel before beginning. Use an insulated screwdriver or a bleed resistor to fully discharge both capacitors before touching terminals — stored voltage can be lethal even with power off. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before disconnecting.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. In stock and ships same business day from our U.S. warehouse when ordered before 3 PM local time.

Compatibility: Engineered as the factory-direct replacement for Carrier model HC1CJX048000ABAA (4-ton R-410A condensing unit). Always cross-reference the MFD and voltage ratings printed on your existing capacitors and the unit's data plate before finalizing your order.
