The contactor is a high-voltage relay controlled by your thermostat's 24V signal — it closes the circuit to power the compressor and condenser fan motor every time a cooling call is made. When the contactor fails, the most common symptoms are an AC system that won't turn on at all, a compressor that fails to engage despite the thermostat calling for cooling, or pitting and burning on the contact points that cause intermittent or failed starts.
