OEM Carrier Single-Pole Contactor 1-Pole 24V 30A for Model PH14NB01800GAAAA

This is the genuine OEM factory-specified contactor for the Carrier PH14NB01800GAAAA heat pump unit, carrying Carrier part number HN51KC024. The contactor is the high-voltage switching relay that responds to a 24V signal from the thermostat or control board to energize the compressor and/or condenser fan motor. When it fails, the result is typically a complete loss of cooling or heating — the outdoor unit simply will not power on, or it may hum and buzz without the compressor starting. Burned or pitted contacts and a failed coil are the most common failure modes.

• Specs: 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz rated
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact specifications for your unit. Generic contactors may not meet the precise contact gap, coil pull-in voltage, or LRA tolerance required, risking premature failure or compressor damage.
• Install difficulty: 2/5 — Always shut off power at both the breaker and the disconnect before proceeding. Photograph all wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify 24V coil pull-in after installation with the thermostat calling for cooling.
