The contactor is the high-voltage switching relay that receives a 24-volt signal from your thermostat and closes the circuit to power the compressor and\/or condenser fan motor. When the contactor fails — due to pitted or welded contacts, a burned coil, or worn contact surfaces — the system will either refuse to start, stay locked on continuously, or trip the breaker. Replacing a failed 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 1-Pole | 24V AC Coil (50\/60 Hz) | 25 FLA (Full Load Amps) | Definite Purpose Contactor | OEM Part # HN51KB024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use factory-spec contact alloys and coil windings calibrated for your unit's exact pull-in voltage.
