Question 1

Why does the freezer of the refrigerator completely defrost while the fridge operates normally?

Accepted Answer

If the contents of your freezer completely defrost while the refrigerator compartment works properly, it indicates that cold air is no longer reaching the freezer. This is usually a problem of air circulation between the two zones, not a major fault of the compressor.

Most likely causes:

Blocked damper - This is the most common cause. This small mechanism controls the flow of cold air from the cooling unit to the drawer freezer. If it gets stuck in the closed position, the freezer receives no cold air.
Cold air duct obstructed by frost - The pipe that channels air from the fridge to the freezer may be partially or completely blocked by a buildup of ice.
Sealing defect in the distribution circuit - An air leak at the internal connections causes cold air to escape before it reaches the freezer.

Solution: This type of repair requires the intervention of a qualified technician, who will need to access the internal components of the RBM90S5FPNS (damper and air ducts) to identify and correct the problem. If your appliance is still under warranty, immediately contact BERTAZZONI customer service for free assistance.

In the meantime: Keep your frozen foods in a neighbor's or friend's freezer, or temporarily invest in dry ice to preserve sensitive foods.

Question 2

Why is the freezer temperature continuously flashing on my BERTAZZONI refrigerator?

Accepted Answer

A flashing temperature display in the freezer generally indicates a cold air circulation problem between the refrigerator compartment and the freezer, or an abnormal reading from the temperature sensor.

Possible causes on the RBM90S5FPNS:

Blocked air damper - This is the most common cause. The damper that regulates the flow of cold air from the freezer to the fridge is not opening/closing properly, causing temperature fluctuations.
Frost or obstruction in the cold air circuit - Ice crystals may block the internal air circulation ducts.
Temperature sensor (NTC) failure - The thermistor measuring the freezer temperature may be faulty, leading to the flashing display.
Leak in the air distribution circuit - A leak prevents the correct transmission of the cold flow.

What you can check before calling a technician:

Rear ventilation space - Ensure there is at least 10 cm of free space behind the refrigerator. Lack of ventilation can cause the compressor to overheat and lead to erratic readings.
Audible check of the compressor - Approach the back of the appliance: you should hear a continuous humming from the motor. If it’s silent, the compressor is not working.
Condition of the internal back - If you can access the internal back panel (some models allow for inspection), check for any abnormal frost buildup.

Important: According to the documentation for the RBM90S5FPNS, any diagnosis or repair of the damper and internal cold air circuits requires intervention by a qualified technician. Do not attempt to force access to internal components.

Contact the BERTAZZONI customer service by providing: the model RBM90S5FPNS, the fact that the freezer temperature is continuously flashing, and your observations on the compressor's operation. This will expedite the diagnosis.

Question 3

What does the error code CE displayed on the freezer temperature panel mean?

Accepted Answer

The error code CE displayed on the temperature panel of your Bertazzoni REF704BBNPTC indicates a communication failure between the main board and the display panel. This is not a failure of the cooling system itself.

What does this code mean exactly?

The main electronic board of the appliance is unable to communicate properly with the control panel (control screen)
This is an electronic communication issue, not a failure of the motor or refrigeration system
The display of the CE code occurs silently - there is no audible alarm

What about the operation?

Your refrigerator continues to cool normally even when this code is displayed. The compartments maintain the programmed temperatures (refrigerator at 2-8°C and freezer at -15 to -25°C depending on your settings). The appliance is therefore not in immediate danger.

What to do?

Although cooling continues, this communication failure indicates an electronic problem that may worsen. You should quickly contact Bertazzoni customer service or a qualified refrigeration technician to diagnose and repair the connection between the motherboard and the display panel. Do not wait too long, as this failure could evolve and affect other functions of the appliance.

Question 4

What does the CE marking on this refrigerator mean?

Accepted Answer

The CE marking on your BERTAZZONI REF704BBNPTC refrigerator confirms the compliance of the product with all relevant European requirements regarding safety, health, and the environment.

In particular, this marking certifies that:

Electrical safety - The appliance meets standard electrical safety requirements for residential appliances
WEEE Directive (2012/19/EU) - The refrigerator is labeled in accordance with the European directive on waste electrical and electronic equipment, ensuring proper treatment at the end of its life

The CE mark stands for “European Conformity”. It is a legal requirement for all electrical appliances sold in the European Union. This mark guarantees that your appliance has been checked and meets all mandatory standards, ensuring safe and responsible use.
