This is the genuine OEM Carrier contactor (part #HN51KC024) factory-specified for the Carrier PH13NR048000AEAA heat pump condensing unit. The contactor is the high-voltage relay that closes when your thermostat sends a 24V signal, routing line voltage to the compressor and condenser fan motor. When it fails, symptoms include the system not turning on at all, audible chattering or humming from the contactor, the unit running continuously and failing to shut off, or visibly pitted and burned contact points inside the control compartment.
Compatibility: Direct OEM replacement for Carrier model PH13NR048000AEAA heat pump condenser. Also cross-references Carrier/Bryant/Payne part numbers HN51CC024, P282-0311, P282-1304, P282-1305, and others. Always verify pole count, coil voltage, and amp rating against your unit's wiring diagram before ordering. Our fitment team is available to confirm compatibility before you buy — order today and get it shipped the same day.
