5.4. Freezer Fan Motor

The Freezer Fan Motor is fed by direct voltage (Vdc) and fixed to the rear cover of the evaporator
through a rubber flexible holder, that protects from occasional vibrations, and consequently noise. It is
responsible for the forced air circulation inside the product, as much the Freezer as 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 Freezer door 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.
