The contactor is the electrical gatekeeper of your system — when the thermostat sends a 24V signal, the contactor closes its contacts to deliver line-voltage power to the compressor and\/or condenser fan motor. A failed contactor is one of the most common causes of an air conditioner that won't turn on, hums with no start, or trips the breaker repeatedly. Pitted, burned, or welded contacts are telltale signs it's time for a replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 25 FLA (Full Load Amps) | 24V AC 50\/60Hz Coil | Definite Purpose Contactor | Factory-matched OEM tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor is manufactured to Carrier's exact contact gap, coil impedance, and pull-in voltage specifications.
