The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to energize the compressor and condenser fan motor. When it fails, common symptoms include the outdoor unit refusing to start, a loud buzzing or chattering noise from the control compartment, welded or pitted contacts that keep the unit running non-stop, or a visibly burned\/melted contact assembly.
