OEM Carrier Single-Pole Contactor 30A 24V Coil for Model PH13NR036000ACAA — HN51KC024

This is the genuine OEM factory-replacement contactor for the Carrier PH13NR036000ACAA heat pump condenser. The contactor is a high-voltage relay that closes when the thermostat sends a 24V signal, allowing line voltage to reach the compressor and condenser fan motor. When the contactor fails — through burned contacts, a welded plunger, or an open coil — the outdoor unit will not respond to a cooling or heating call, even when the thermostat is functioning correctly. You may hear the indoor air handler running while the outdoor unit stays completely silent.

• 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 OEM contactor is manufactured to Carrier's exact factory specifications, ensuring proper coil pull-in voltage, contact gap, and silver-alloy contact material. Generic aftermarket contactors often use lower-grade contact alloys that pit and weld prematurely under compressor start loads.
• Install Difficulty: 2/5 — Always disconnect and lock out ALL power before opening the control panel. Photograph all wiring before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify coil continuity and confirm 24V signal). Label line and load terminals carefully before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
