4.3. Freezer Fan Motor
The Fan motor is a (V dc) motor and is fixed to the rear cover of the evaporator through a rubber flexible holder
(freezer), that protects from occasional vibrations, and consequently noise.
4.4. Refrigerator Fan Motor
The Refrigerator fan motor is also fed by direct voltage (V dc), 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.
