The contactor is a high-voltage relay that switches line-voltage power to the compressor and condenser fan motor when it receives a 24V signal from the thermostat or control board. A failed contactor is one of the most common reasons a system runs at the air handler but the outdoor unit won't energize — symptoms include a humming outdoor unit with no compressor start, burned or pitted contact points, or a system that fails to respond to a cooling or heating call entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole configuration | 24V control coil | Factory OEM part number HN52TC040 | High-cycle-rated contact points for reliable long-term switching\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is manufactured to Carrier's exact coil voltage and contact ampacity specifications.
