The transformer steps down line voltage (120V) to 24V AC to power the control board, thermostat, contactor coil, and all low-voltage safety circuits. When it fails, the result is total loss of thermostat response, a blank display, or a tripped fuse — the system appears completely dead even though line voltage is present.
