The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage control circuits. When this part fails, the entire control circuit goes dark — nothing works: no heat, no fan, no thermostat response. A failed transformer is often the overlooked culprit when a furnace appears completely dead but the power supply is confirmed good.
