OEM Carrier Dual Run Capacitor 45+5 MFD 440V for Model PY4GNAB36060AA

This is the genuine OEM factory-specified dual run capacitor for the Carrier PY4GNAB36060AA split-system air conditioner, OEM part number P291-4554RS. The dual run capacitor provides the electrical charge required to start and sustain both the compressor and condenser fan motor simultaneously. When this component fails, you'll typically hear a low hum with no motor movement, experience a hard-starting compressor, or notice the outdoor unit shutting down within minutes of starting — all classic signs of capacitor failure that should be addressed immediately to prevent compressor damage.

• Specs: 45+5 MFD (microfarad) | 440V rated | Round case | 50/60 Hz | ±6% tolerance | Castor oil protected | No-PCB construction | Replaces legacy part numbers HC98KA046 and 319186-702
• OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerances. Generic alternatives commonly run at ±10% MFD variance, which places unnecessary stress on your compressor windings and condenser fan motor, shortening their operational lifespan significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter. Photograph all wiring connections before disconnecting the old capacitor to ensure correct re-wiring of HERM, FAN, and COMMON terminals.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
