The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to supply line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the most common symptoms are an AC unit that won't turn on at all, a compressor that won't start despite the thermostat calling for cooling, or a unit that runs continuously without shutting off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V coil voltage | Factory-rated amperage for Carrier CP50P450P405010CP | OEM part number HN53CD115 | Direct drop-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contact tips rated to factory specifications, ensuring proper inrush and continuous current handling.
