The contactor is the high-voltage relay that receives a 24V signal from the thermostat or control board and closes the circuit to power the compressor and condenser fan motor. When the contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the system either won't turn on at all, runs continuously without cycling off, or trips the breaker repeatedly. Replacing a worn contactor restores reliable switching and protects your compressor from voltage irregularities.
