The contactor is a high-voltage relay controlled by the 24V signal from your thermostat or control board — when energized, it closes the high-voltage circuit to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a packaged unit simply won't turn on, buzzes without starting, or runs intermittently. Pitted or burned contacts, a stuck plunger, or a failed coil are all telltale signs it's time for a replacement.
