OEM Carrier 2-Pole Contactor 24V Coil for Model PY3GNAA42060AA

This is the genuine OEM replacement contactor for the Carrier PY3GNAA42060AA packaged unit. The contactor is the high-voltage relay responsible for switching 240V power to the compressor and condenser fan motor every time the thermostat calls for cooling. When the contactor fails — due to burned or pitted contacts, a coil that no longer energizes, or contacts that weld shut — the result is either an AC that won't start at all, one that runs continuously regardless of thermostat demand, or a unit that hums and trips the breaker. Replacing it with the factory OEM part (Carrier part number HN51KC024) ensures reliable, code-compliant performance without guesswork.

• Specs: 2-pole design | 24V AC coil voltage | Rated for 40A+ compressor loads | Factory-matched contact gap and coil pull-in voltage per Carrier specifications
• OEM vs Generic: OEM Carrier contactors are manufactured to exact coil impedance and contact silver-alloy specs. Generic alternatives frequently use thinner contact material, leading to premature pitting, arcing, and nuisance call-backs — especially under the high inrush currents of scroll compressors.
• Install Difficulty: 2/5 — Turn off power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to confirm voltage is absent before touching terminals. Photograph all wire connections prior to removal. Swap wires one-at-a-time to avoid miswiring.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.
