The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, contactors, and all low-voltage safety circuits. When this component fails, the entire control circuit goes dead — the thermostat goes blank, the system refuses any call for heating or cooling, and no relays or contactors will energize.
