The control board is located inside the
refrigerator compartment, and contains
the microprocessor which controls the
operation of the appliance, the buzzer
and the reed-element.
The power board is located in the compressor compartment, and
contains the triac for the following outputs:

The power board is also fitted with a 24V DC transformer for the
fans.
In addition, a safety NTC fitted to the power board interrupts
operation of the compressor if the temperature exceeds 75°C; the
NTC switches the compressor on again when the temperature falls
to below 65°C, thus keeping the fans in operation.
The connection box is located inside the freezer compartment. The
NTC sensors, heaters, evaporator fan and freezer door switch are
connected to the connection box.
