OEM Carrier 1-Pole Contactor 30 Amp 24V Coil for Model PH13NR03000GAEAA — HN51KC024

This is the factory OEM contactor for the Carrier PH13NR03000GAEAA heat pump/air conditioning system. The contactor is the high-voltage relay that receives the 24V signal from your thermostat and closes the circuit to power the compressor and condenser. When it fails, the most common symptom is the outdoor unit failing to respond to a cooling call — you'll hear the air handler running inside but the compressor and fan outside remain silent. Pitted or burned contacts from years of arcing are the leading cause of failure on contactors of this age and duty cycle.

• Specs: 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz | OEM Part Number HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact OEM contact gap, coil impedance, and housing tolerances. Generic aftermarket contactors often use lower-grade silver alloy contacts that pit faster, reducing service life and increasing the risk of contact welding.
• Install difficulty: 2/5 — Always disconnect power at both the breaker and the disconnect block before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph existing wiring before removing any leads. Coil leads are polarity-independent on this unit.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
