OEM Carrier Single-Pole Contactor 1-Pole 24V 30A — HN51KC024 for Model PH14NA048000BAAA

This is the factory OEM replacement contactor for the Carrier PH14NA048000BAAA heat pump. The contactor is the high-voltage relay that bridges 240V power to your compressor each time the thermostat calls for cooling or heating. When the 24V control signal energizes the coil, the contacts close and the compressor starts. A worn or failed contactor is one of the most common reasons a heat pump will hum but not start, fail to turn on at all, or run continuously without shutting off — symptoms that often lead to costly refrigerant and compressor damage if left unaddressed.

• Specs: 1-Pole (single-pole) | 24 VAC coil voltage | 30 FLA (Full Load Amps) | 150 LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact factory tolerances. Generic contactors often use lighter-gauge contacts that pit and burn faster under the high inrush current of compressor starts, leading to repeat failures. OEM contactors deliver longer service life and preserve your compressor warranty coverage.
• Install difficulty: 2/5 — Disconnect and lock out all power before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removing the old contactor. Note: coil terminals may be on opposite sides from the original — verify against your unit's wiring diagram before energizing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
