The contactor is the high-voltage relay that closes the circuit to your compressor and condenser fan motor each time your thermostat calls for cooling or heating. When it fails, your system may fail to start entirely, drop out mid-cycle, chatter loudly at the unit, or show burned or pitted contact points on inspection. Replacing a worn contactor promptly protects your compressor — the most expensive component in any system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole | 40A FLA (Full Load Amps) | 24V 50\/60Hz coil voltage | 240\/277V load voltage | Factory-matched OEM tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM contactor built to exact factory specifications.
