The contactor is a high-voltage relay controlled by a low-voltage (24V) signal from the thermostat or control board. When the thermostat calls for cooling, the contactor closes its poles to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioning system that powers on but won't cool — symptoms include the outdoor unit failing to start, visible pitting or burning on the contact points, or a contactor that is stuck open or welded shut.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier C4850C50AJ04111 | Heavy-duty silver alloy contact points for long service life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor is manufactured to exact Carrier factory specifications.
