The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When a contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the most common symptom is an air conditioner that simply won't turn on, even though the thermostat is calling for cooling. You may also hear a clicking or chattering sound from the outdoor unit with no compressor startup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | Rated for high-amperage compressor loads | Direct factory replacement for OEM part number HN51KB024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor meets Carrier's exact contact material and coil voltage tolerances.
