The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes to deliver line voltage to the compressor and condenser fan motor. When a contactor fails — due to burned or pitted contact points, a stuck plunger, or a failed coil — the outdoor unit will not energize at all, or may run continuously without shutting off. Replacing the contactor is one of the most common and cost-effective AC repairs available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | 30–40 amp rated | Direct OEM replacement — matches factory wiring, mounting footprint, and terminal layout for the CH16NA04800GBAAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contact tips rated for thousands of switching cycles.
