The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC unit won't turn on at all, or runs intermittently. Signs of failure include burnt or pitted contact points, a chattering or buzzing noise from the outdoor unit, or a system that simply won't energize despite a good thermostat signal.
