The contactor acts as a high-voltage relay, receiving a 24V signal from the thermostat or control board to close its poles and deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or contacts that weld shut — the system either refuses to start, runs continuously without cycling off, or trips the breaker repeatedly. Replacing the 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 2-pole configuration | 24V coil voltage | 40–50A contact rating | Direct OEM replacement — matches factory wiring footprint exactly.
