The contactor is the critical switching component that receives the 24V signal from the control board and closes the high-voltage circuit to energize the compressor and condenser fan motor. When a contactor fails, the most common symptoms are an AC system that won't turn on at all, a compressor that won't engage despite the thermostat calling for cooling, or visible pitting and burning on the contact points inside the relay.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 3-pole configuration | 24V AC\/DC coil voltage | 40A continuous current rating | Max 600V load side | Screw-mount terminal design | Factory-matched replacement\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.
