The contactor acts as the primary electrical switch that allows the 24V thermostat signal to energize and control the high-voltage compressor and condenser fan motor circuits. When the contactor fails, the most common symptoms include the AC unit failing to turn on at all, the compressor not engaging despite the thermostat calling for cooling, or audible chattering and buzzing from the contactor coil. Pitted or burned contacts are also a telltale sign of a worn contactor that needs immediate replacement.
