The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, contactor coil, gas valve, and control board. When this component fails, nothing in the system responds: the thermostat goes dark, the contactor won't pull in, and the unit sits completely unresponsive.
