ELECTRONIC CONTROL BOARD

The difference between the full electronic specification cabinet and the mid electronic specification
cabinet are as follows:
The full electronic specification cabinet consists of a main high voltage board located in the
compressor compartment with a display board mounted in the top of the fresh food compartment,
and a dispenser board mounted in the front of the freezer compartment. These three boards
control the many features of the fully electronic product using a switch mode power supply.
The mid electronic specification cabinet has only the two boards, one being mounted in the roof of
the fresh food compartment and the other being the dispenser board, using a capacitive power
supply, mounted in the front of the freezer door. This results in a less number of feature buttons
available for the customer to access and less digits displayed. The service technician does not
have access to all the diagnostic features of the fully electronic spec cabinet.
