The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, contactor coils, and all low-voltage control circuits. When this component fails, the entire control system goes dark — the thermostat loses power, the unit won't respond to calls for heating or cooling, and nothing operates.
