The contactor is the high-voltage relay that bridges the 24V control circuit to the high-voltage compressor and condenser fan circuits. When the thermostat calls for cooling, the 24V coil energizes and pulls in the contacts, sending line voltage to the compressor. When this part fails, the most common symptom is the outdoor unit simply not turning on — even though the thermostat is calling and the air handler is running — or intermittent cycling caused by worn or pitted contact points.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole | 40 FLA (Full Load Amps) | 24V 50\/60Hz Coil | 240\/277V switching voltage | Direct OEM factory replacement for part number HN52TC040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Carrier contactor is manufactured to exact factory specifications, including precise coil resistance, contact gap, and silver-alloy contact material.
