The contactor acts as the primary switching device that allows 240V power to flow to the compressor and condenser fan motor when the thermostat calls for cooling. When it fails, the most common symptoms are an outdoor unit that won't energize at all, audible chattering or buzzing at the contactor, or a system that short-cycles and trips the breaker. Burned or pitted contacts are a leading cause of premature compressor failure — replacing a worn contactor promptly protects the most expensive component in your system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole | 30 Amp | 24V AC coil voltage | 240V load voltage | Factory-matched contact material and spring tension to OEM specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contacts rated to factory arc-interruption specs.
