The contactor acts as the primary electrical switch that receives a 24V signal from the thermostat and closes the high-voltage circuit to energize the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will either refuse to start entirely, run continuously without shutting off, or trip the circuit breaker repeatedly.
