Has added features: a variable temperature adjustment for those "fixed temp" refrigerators. The check light comes on after each ignition try that fails to sense a flame. The board repeats the 3 try ignition cycle at 30 minute intervals if no flame is sensed. On 3-way units the DC mode light will flash and the DC element will be disconnected if the DC voltage falls to an inadequate level for more than 10 seconds.
