OEM Carrier Single-Pole Contactor 1P 30A 24V — Model PY4GNAA24060AA (HN51KC024)

This is the factory-original OEM replacement contactor for the Carrier PY4GNAA24060AA packaged unit. The contactor is a high-voltage relay energized by the 24V control circuit — it closes to send line voltage to the compressor and/or condenser fan motor every time your thermostat calls for cooling. When a contactor fails, the most common symptoms are an AC unit that won't power on, buzzing or chattering from the control compartment, or a system that trips the breaker due to welded/pitted contacts that won't open.

• Specs: 1 Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50/60 Hz | OEM Part # HN51KC024
• OEM vs Generic: This is a Carrier Factory Authorized Part built to exact OEM contact-gap and coil-resistance specifications. Generic contactors often use thinner contact silver alloy, leading to faster pitting and premature failure — especially in high-cycle southern climates.
• Install Difficulty: 2/5 — Shut off power at both the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removal. Verify 24V coil pull-in with a multimeter after installation before restoring full power.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
