OEM Carrier 1-Pole Contactor 30 Amp 24V Coil — HN51KC024 for Model PH10JA04200GABAA

This is the factory-authorized OEM replacement contactor for the Carrier PH10JA04200GABAA packaged heat pump unit. The contactor is the high-voltage relay that energizes your compressor and fan motor every time the thermostat calls for cooling or heating. When the contactor fails — due to pitted contacts, a welded/stuck plunger, or an open coil — the system will either refuse to start at all, run continuously without shutting off, or fail to respond to thermostat commands. Replacing with the correct OEM part restores factory-specified switching performance and protects the compressor from premature failure.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact OEM specifications — not a generic substitute. Generic contactors often use lower-grade contact materials that pit faster under high inrush loads, shortening compressor life and causing nuisance lockouts.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in with a meter after installation before restoring load power.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
