OEM Carrier Single-Pole Contactor 30A 24V (HN51KC024) for Model PH13NR036000AEAA

This is the factory OEM single-pole contactor for the Carrier PH13NR036000AEAA heat pump system. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to power the compressor. When it fails, the most common symptoms are an air conditioner or heat pump that won't turn on at all, a system that clicks but never starts, or pitted/burnt contacts visible on inspection. Replacing a worn contactor is one of the most cost-effective repairs you can perform on a residential HVAC system.

• Specs: 1-Pole | 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 genuine Carrier Factory Authorized Part is manufactured to exact factory tolerances, ensuring proper coil pull-in voltage and contact life. Generic contactors frequently use lower-grade contact materials that pit and weld shut faster under compressor cycling loads, shortening system life.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Photograph all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify 24V coil signal. Swap wires one at a time to avoid miswiring.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
