OEM Carrier Single-Pole Contactor 30A 24V for Model PH13NR03600GAEAA

This is the factory OEM replacement contactor for the Carrier PH13NR03600GAEAA heat pump / air conditioning system. The contactor is a high-voltage relay controlled by the 24-volt thermostat circuit — when the thermostat calls for cooling, the 24V coil energizes and closes the contacts, sending line voltage to the compressor. When the contactor fails, the system will typically hum without starting, fail to respond to thermostat calls entirely, or trip the breaker due to welded or pitted contacts. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs.

• Specs: 1-Pole (single-pole) | 30 Amps | 24 VAC coil voltage | 50/60 Hz | OEM Part Number: HN51KC024
• OEM vs Generic: This OEM unit is factory-matched to the exact coil pull-in voltage and contact ampacity specified for the Carrier PH13NR03600GAEAA. Generic aftermarket contactors often use lower-grade contact materials that pit and weld more quickly under compressor inrush loads, shortening service life.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in after installation with a thermostat call.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
