The contactor is a high-voltage relay controlled by the 24V signal from your thermostat and control board.

A failed contactor is one of the most common reasons an AC unit won't turn on — symptoms include the outdoor unit staying completely off, chattering or buzzing from the contactor coil, or visible pitting and burning on the contact points.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | 40–50A contact rating | Direct OEM replacement for part number HN53CB115 | Factory-matched electrical tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor uses factory-spec contact materials and coil windings.
