5.3. Sensor

Check the correct position of the freezer sensor on its housing;
Its wires should run downwards to prevent them from being broken.
Right
Wrong
The temperature value is measured close to the sensor and not at the center of the refrigerator or freezer
compartment.
When the product is for the first time connected to the electrical power supply, the interface panel will start with
the factory pre-selected temperature; medium level.
If the product is disconnected during its use, or lack of energy occurs, it will assume the last
function/programming done by the user when reconnected. When this lack of power makes the freezer and
defrost sensors temperatures upper than +20º c, the control will assume the pre-selected factory temperature.
When necessary, do the check of temperatures / resistances of the sensor in its terminals on the control board.
All operation range must be in accordance to the selection (temperature) done on the interface panel, and the
software of the electronic control will convert as following:
