Owners of brand refrigeration equipment Vestfrost often face the need change the operating temperature of the unit. Situations can be different: you need to defrost the lower compartment, save energy during a long absence, or simply reduce the load on the compressor. However, the design of most modern models does not provide for physically turning off only the freezer without stopping the entire refrigerator.
Nevertheless, there are effective ways to control the temperature that can minimize the formation of cold in the freezer. In this article, we will analyze in detail software configuration methods, the use of special modes and technical nuances that will help you achieve the desired result without the risk of damaging your equipment.
Understanding the principles of operation No Frost systems and static cooling will help you correctly interpret thermostat readings. It is important to consider that completely shutting off one of the circuits is often impossible due to the design features of heat exchange between the chambers.
Design features of Vestfrost refrigerators
Danish brand refrigerators Vestfrost are known for their reliability and thoughtful engineering. Most models are equipped with a dual-circuit or single-circuit cooling system. In single-circuit systems, cold is generated in the freezer compartment and then distributed to the refrigerator compartment. That is why complete shutdown the freezer in such models automatically leads to defrosting of the main compartment.
More modern models, especially with the system No Frostmay have separate evaporators. However, even in this case, the electronics often block the ability to independently control compressor power for one zone. Control is carried out through a single module that regulates the operation of the compressor and fans.
Why can’t you just cut the wires?
Inside the refrigerator there is refrigerant and a complex electrical circuit. Any intervention in the wiring without the appropriate qualifications will lead to a short circuit, failure of the control board or, in the worst case, to a freon leak and the need for expensive repairs with refilling the system.
It is important to note that attempts to mechanically disconnect heating elements or fans can upset the temperature balance. Air circulation in the chambers must remain unobstructed to prevent the formation of ice traffic jams and mold.
Software shutdown via the control panel
The safest and most correct way to change the operating mode is to use a standard control panel. Depending on the model Vestfrost, the interface can be represented by mechanical regulators or an electronic display. For models with electronics, the “Vacation” or “Eco” mode is often available, which increases the temperature in the refrigerator compartment, but leaves the freezer running.
To reduce the temperature in the freezer compartment as much as possible programmatically, you need to find a power control function. It is usually indicated by snowflakes or numbers from 1 to 7. By setting the minimum value, you will force the compressor to turn on less often. However, remember that safe minimum a temperature of -12°C is considered, below which food can begin to deteriorate.
Some advanced models allow you to activate the function Super Cool or Super Freeze with a reverse timer, but for our task we need to do the opposite - look for energy saving modes. If the instructions for your model Vestfrost CNF or VC series do not directly indicate independent control, then this option is not implemented by the manufacturer.
Using the Holiday mode and its effect
Holiday Mode is a standard feature for many European brands, including Vestfrost. Its main purpose is to prevent the appearance of odor and mold in the refrigerator compartment during a long absence of the owners, while keeping food frozen in the lower compartment.
When this mode is activated, the temperature in the upper compartment rises to +12...+15°C. This is not enough for storing perishable food, but it is enough for ventilation. The freezer continues to operate normally. Unfortunately, invert this process, leaving the cold only at the top, is technically impossible in domestic conditions.
⚠️ Attention: Leaving the refrigerator for a long time at elevated temperatures without regular washing can lead to the growth of bacteria in the drainage system. Before turning on the “Vacation” mode, be sure to empty the refrigerator compartment of food.
Activation of the mode is usually done by long pressing the button with the image of a palm tree or suitcase. The corresponding indicator lights up on the display. If your model does not have a display, consult the instructions, since this mode may not be available on mechanical models.
Physical limitation of cold access
If software methods do not give the desired result and you critically need to reduce the cold output in the freezer compartment (for example, to store vegetables there that should not freeze), you can resort to physical methods. They do not turn off the camera completely, but they significantly change the temperature profile.
The essence of the method is to isolate the space. You can fill the free volume of the freezer with heat-insulating materials, for example, polystyrene foam or thick blankets (if the chamber is empty and dry), or, conversely, fill it with buffer products that will maintain the temperature. But the method of partially blocking the air channels is more effective.
☑️ Safely lowering the temperature in the freezer
In models with the system No Frost cold is pumped by a fan through special channels. Partial blocking of these channels (no more than 30% of the area) will reduce the cooling intensity. However, this must be done with extreme caution so as not to cause overheating of the compressor due to insufficient heat exchange.
| Method of exposure | Efficiency | Risk to equipment | Influence on products |
|---|---|---|---|
| Vacation mode | Low (for freezer) | Absent | Safe |
| Minimum thermostat | Medium | Low | Thawing is possible |
| Channel blocking | High | Medium (overheating) | Uneven cold |
| Fan shutdown | Very high | High (combustion) | Food spoilage |
Saving energy during operation freezers
Often the desire to turn off the freezer is dictated by the desire to save on electricity. The freezer consumes a significant portion of the refrigerator's energy by maintaining low temperatures. If you do not use the bottom compartment, its maintenance may indeed be unprofitable.
To optimize costs, it is recommended to check the door sealing rubber bands. If they do not fit tightly, the cold escapes and the compressor runs in vain. Regular cleaning the condenser (grids at the back of the refrigerator) from dust also reduces energy consumption by up to 20%.
Another tip is to adjust the temperature according to the load. An empty freezer is easier to keep cold, but when you open the door, the temperature drops faster than a full one. Therefore, if you are not using a camera, it is better to fill the available space with plastic water bottles. This will create thermal inertia and stabilize the temperature.
What you should absolutely not do
In the pursuit of solving a problem, users sometimes make mistakes that lead to the breakdown of expensive equipment Vestfrost. There are a number of actions that are prohibited by the instructions and operating rules for electrical appliances.
Never try to turn off the power to the freezer by cutting the wires inside the case or disconnecting the terminals from the defrost heating element without understanding the electrical diagram. This may result in a short circuit, fire or electric shock. In addition, such actions will void warranty obligations the manufacturer's warranty.
⚠️ Attention: In modern electronically controlled models, the disconnection of any sensor or actuator is perceived by the board as a malfunction. The refrigerator may go into emergency mode and stop cooling both chambers completely.
It is also not recommended to use external timers to cycle the refrigerator on and off from the outlet. Frequent starts of the compressor without rest (less than 10-15 minutes of inactivity) lead to its rapid wear and jamming of the piston group.
Frequently asked questions (FAQ)
Can a Vestfrost refrigerator be used only as a refrigerator?
Technically, if do not use the freezer, it will simply be empty. But you cannot disable it separately. If you only need a refrigerator, the freezer will still consume compressor life. Some users install a thermostat in the freezer, which opens the circuit when a certain temperature is reached, but this requires the skills of an electrician.
Why does the freezer not turn on after defrosting?
Perhaps the compressor protection has tripped or the contact of the temperature sensor has come loose. Let the refrigerator stand unplugged for 30-40 minutes. If the problem is not solved, check whether the regulator is set to position “0”.
How to check if the freezer is working?
Put a piece of ice or a special test cube into the chamber. If after 2-3 hours it freezes or increases in size (due to air moisture), then the camera is working. You can also use a household thermometer.
Is it harmful to keep the freezer empty?
Yes, it is harmful for the compressor. The empty air volume quickly heats up when opened, causing the unit to wear out. Fill the voids with any items that retain cold (bottles of water, bags of cereal).
