The transformer steps down line voltage (120V) to the 24V control circuit voltage that powers your thermostat, contactor coil, gas valve, and all low-voltage safety controls. When this component fails, the entire control circuit goes dead — the thermostat display may go blank, the system won't respond to calls for heating or cooling, and no relays or valves will actuate.
