OEM Carrier Single-Pole Contactor 1-Pole 30 Amp 24V for Model PH13NR048000AAAA

This is the genuine OEM factory-replacement contactor for the Carrier PH13NR048000AAAA heat pump condensing unit. The contactor is the high-voltage relay that responds to the thermostat's 24V control signal, closing to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, welded contacts, or an open coil — the result is a system that simply won't turn on, hums without starting, or runs continuously without shutting off. Replacing it promptly prevents collateral damage to the compressor.

• Specs: 1-Pole configuration | 24 VAC coil voltage | 30 Amp full load rating (FLA) | 150 Amp locked rotor rating (LRA) | 50/60 Hz | OEM Part # HN51KC024
• OEM vs Generic: This OEM contactor is factory-matched to Carrier specifications with verified contact alloy composition and coil resistance tolerances. Generic contactors often use inferior contact materials that pit and weld prematurely — a $15 savings that can lead to a $1,500 compressor replacement.
• Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before beginning. Photograph all wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify contactor pull-in by checking for 24V across the coil terminals on a thermostat call.
• Warranty: 1-year OEM manufacturer warranty. In-stock — ships same business day from our warehouse.
