The contactor acts as the primary electrical switch that sends 240V power to the compressor and condenser fan motor when the thermostat calls for cooling. A failing contactor is one of the most common causes of a non-functioning AC — symptoms include the outdoor unit not energizing, a buzzing or chattering noise from the disconnect area, pitted or burnt contacts, or a system that cools intermittently and stops unexpectedly.\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 CSA0750H2H | Silver alloy contact tips for reduced arcing and extended service life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier contactor built to exact factory specifications.
