The transformer steps down line voltage (120V) to the 24V signal required by your thermostat, control board, contactor coil, and all low-voltage safety circuits. When the transformer fails, the entire control circuit goes dark — your thermostat goes blank, the system won't respond to any call for heating or cooling, and nothing operates.
