OEM Carrier 2-Pole Contactor 24V Coil for Model PY4GNAA30060AA

This is the factory OEM replacement contactor for the Carrier PY4GNAA30060AA split-system air conditioner, sold under OEM part number HN51KC024. The contactor is the high-voltage relay responsible for switching power to your compressor and condenser fan motor every time the thermostat calls for cooling. When it fails — due to worn contacts, pitting, or a burned coil — the outdoor unit will not energize even though the indoor air handler continues to run, leaving you with warm air and a frustrated household.

• Specs: 2-Pole configuration | 24V AC coil voltage | Factory-rated contact amperage | Direct OEM replacement — no modifications required
• OEM vs Generic: OEM contactors (HN51KC024) use factory-spec silver-alloy contact tips rated for thousands of switching cycles. Generic contactors often use inferior contact materials that pit and weld prematurely, shortening compressor life and increasing service callbacks.
• Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. The contactor slides into the control panel bracket and terminals are screw-type for straightforward replacement.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.
