The contactor is a high-voltage relay that acts as the primary switch between the 24V control circuit and the high-voltage compressor and condenser fan motor circuits. When the thermostat calls for cooling, the 24V coil energizes and closes the contacts to send line voltage to the compressor. A failed contactor typically causes the entire outdoor unit to not turn on, or may result in intermittent operation, visible pitting\/burning on the contact points, or a buzzing sound without startup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V AC coil voltage | 2-pole configuration | Factory-matched contact rating | OEM part number HN51KB024 | Direct drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact current specifications.
