Main Control Board description

The Main Board is located in the compressor area and communicate to the User Interface board.

The Main Control Board is installed on Side by Side appliances with In Door Ice Ice- Maker system (current Ice-
Maker) or NOT IDI Ice-Maker system (Ice-Maker Sankyo).

The product is a two compartments (refrigerator and freezer), one compressor automatic defrost appliance.

The main function of electronics is to manage the temperature inside the cavities and to manage the Ice and

Water dispenser controlling consequently the compressor and the other components operations.

The electronic control architecture is as follow:

7-segment IDI/NO IDI Biruni

LCD AKO-DIEHL

7-segment AKO-DIEHL

Main Board “Flextronics” to be

combined with the following User board
