The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, contactor coils, and control board. When it fails, the entire control circuit goes dark — the thermostat appears dead, the system won't respond to any call for heating or cooling, and no diagnostic codes are displayed.
