5.5. Refrigerator Fan Motor
The Refrigerator Fan Motor is also fed by direct voltage (Vdc), therefore, located inside the Wind Flow,
fixed to a plastic Housing by flexible rubber holder, which avoids occasional vibrations and consequently
noise. It is responsible for the forced air circulation inside the Refrigerator Compartment.
This component does not depend on the compressor to work, and its speed (rpm) can range according
to the function/necessity managed by the Electronic Control. The orders it performs are:
•
It receives signals from the Electronic Control to turn on/off, change speed according to the
necessity/function;
•
The Fan Motor
always
turns off when the
one of the doors
(Freezer/Refrigerator)
is opened
.
When closing the door, the Electronic System re-starts controlling the activation of the Fan Motor.
Note: - Except during the Initial Test Routine (factory routine) which has priority over other functions
(see Component Tests) and keep the Fan on during this time.
- In case that one of the Doors remains open during 6min, the Freezer Fan Motor will turn on
automatically
•
After a defrost or compressor start up cycle, the Fan Motor will re-start only when the temperature
differential between the Freezer and the Defrost sensors reaches 2º C, it means it is reactivated
according to the temperature, not according to the time, as it used to be in other product models.

Remark
In order to avoid the return of hot air (re-circulation air) through the Wind flow, whenever the Refrigerator
Fan Motor is "on" the Freezer Fan Motor will also be.
5.6. Temperature Control
The temperature inside the product depends on the quantity of food and the open-door frequency. The
refrigerator and freezer temperature sensors are responsible in checking the inside temperature in each
compartment, sending signals to the electronic control, and it will activate/disable the interface
components so that the inside temperature is kept next to desired, according to selected in the LCD
Display (temperature / function) or automatically by the 6
th
Sense mode.
The temperatures range of each compartment by graduation level are described as follows:
Level – 24

COMMENTS
The temperature value is measured close to the Sensor
and not at the center of the Refrigerator or Freezer compartment.
