OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — Model PH15NA02400GBAAA

This is the factory OEM replacement contactor for the Carrier PH15NA02400GBAAA heat pump. The contactor is the high-voltage switching relay that closes when the 24V thermostat signal calls for cooling or heating, energizing the compressor and condenser fan motor. When it fails — whether from pitted contacts, a burnt coil, or welded-shut contacts — your system will either refuse to start or run continuously without responding to the thermostat. Part number HN51KC024 is the Carrier Factory Authorized replacement, engineered to meet exact OEM specifications for this unit.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50/60 Hz | Screw-terminal line/load connections
• OEM vs Generic: OEM Carrier contactors use factory-spec contact material and coil windings matched to the PH15NA02400GBAAA's control circuit. Generic contactors often use softer contact alloys that pit and weld faster under high-cycle residential use, leading to repeat failures within a single cooling season.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the control panel. Photograph all wiring before removing the old contactor. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V coil signal). Note: low-voltage coil leads may be on opposite sides of the new contactor versus the original — confirm with your unit's wiring diagram.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — in stock and ready to go.
