The contactor is the high-voltage switching relay at the heart of your outdoor unit — when the thermostat sends a 24V signal, the contactor closes and delivers line-voltage power to the compressor. A failed contactor is one of the most common reasons an AC or heat pump stops cooling: symptoms include the system not turning on at all, a loud humming from the contactor coil with no compressor startup, or — in the case of welded contacts — the compressor running continuously even when cooling isn't called for.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 30A FLA \/ 150A LRA | 24 VAC coil voltage | 50\/60 Hz | OEM part number HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a Factory Authorized Part built to exact Carrier specifications.
