OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil (HN51KC024) for Model PH13NA03000GABAA

This is the factory OEM replacement contactor for the Carrier PH13NA03000GABAA heat pump. The contactor is the primary high-voltage switching relay in your condensing unit — it receives a 24V signal from the thermostat and closes the circuit to energize the compressor and/or condenser fan motor. When the contactor fails, the most common symptoms are a unit that won't turn on despite a thermostat call, a buzzing or chattering sound from the outdoor unit, or a compressor that runs continuously because pitted contacts have welded shut. Worn contacts are among the most frequent causes of summer no-cool service calls and are an affordable fix when caught early.

• Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part Number: HN51KC024
• OEM vs Generic: This is a genuine Factory Authorized Part built to exact Carrier specifications. OEM contactors feature precision contact surfaces and factory-rated coil windings — generic aftermarket units often use lower-grade contact materials that pit faster under cycling loads, shortening service life significantly.
• Install Difficulty: 2/5 — Disconnect and lock out all power before opening the unit. Photograph all wiring connections before removing the old contactor. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify 24V coil signal. Confirm contactor pull-in with a thermostat call after installation.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse — get your system back online fast.
