Modern refrigerators of the Finnish brand Helkama are deservedly in demand due to their reliability and energy efficiency. However, after purchasing or moving equipment to a new location, owners are often faced with the need for correct initial setup. Correct temperature control is not just a matter of comfort, but also a guarantee of food safety, as well as the durability of the compressor.
Incorrectly set parameters can lead to rapid spoilage of perishable goods or, conversely, to their deep freezing, which changes taste. In this article, we will look in detail at how to set temperature in the Helkama refrigerator, taking into account the features of various models, from classic mechanical thermostats to modern digital control systems.
Understanding the operating principles of your unit will help you avoid common mistakes. Many users do not know that the initial startup takes time, and a sudden change in settings can be perceived by the electronics as a failure. Let's look at all the nuances of setting so that your Helkama works in optimal mode.
Initial setting and stabilization time
Before you begin to actively adjust temperature indicators, you need to give the refrigerator time to stabilize after transportation. If the unit has just been delivered, it needs to stand in an upright position for at least 2-4 hours so that the oil in the compressor returns to the crankcase. After connecting to the network, you should not immediately load the shelves with products.
Let the device idle. During this period, the electronics or mechanical thermostat will attempt to reach the basic factory settings. Typically this process takes from 4 to 8 hours depending on the ambient temperature in the room. Only after the refrigerator has completed one full cycle and automatically turns off, you can fine-tune it to suit your needs.
⚠️ Attention: Do not try to speed up the cooling process by setting the minimum possible values immediately after turning on. This can lead to overload of the compressor and false activation of the protective mechanisms.
It is important to consider that an empty refrigerator gains cold faster, but also holds it worse when the door is opened. Therefore, it is better to carry out the initial setup when the chambers are at least 30-40% full (water bottles can be used). This will provide a more stable thermal background for calibrating the sensors.
Adjusting the mechanical thermostat
In classic models Helkama, such as the HC series or older modifications, control is carried out using a rotary regulator located inside the refrigerator compartment. This is usually a round knob with numbers from 1 to 5 or Min to Max. It is important to remember the main rule here: a larger number means a lower temperature (more cooling).
For most everyday situations, the optimal position of the regulator is at 2 or 3. This corresponds to the range of +3...+5°C, which is ideal for storing most products. If you set the value to 5 (Max), the compressor will work almost non-stop, trying to reach extremely low temperatures, which can lead to icing of the evaporator.
- ❄️ Position 1 (Min): Minimum cooling mode, suitable for storing vegetables in large volumes or at very low room temperatures.
- ❄️ Position 3 (Medium): Standard mode for daily use, providing a balance between food safety and energy consumption.
- ❄️ Position 5 (Max): Intensive freezing or super-cooling mode, used for a short time to quickly cool a large amount of warm food.
Mechanical thermostats have a certain inertia. After turning the knob, the temperature inside the chamber does not change instantly, but over several hours. Therefore adjusting the settings should be done smoothly, taking breaks between changes in the position of the regulator.
Electronic display control
More modern models Helkama, including two-chamber and multi-chamber units, are equipped with an electronic control unit with a display on the outside of the door or inside the chamber. Here the adjustment is made with an accuracy of a degree. To change settings, you typically use the Up/Down arrow buttons or the touchpad.
To change the temperature in the refrigerator compartment, you often need to press and hold the appropriate button (indicated by a snowflake or thermometer symbol) for 3-5 seconds until the indicator light flashes. After this, the arrows set the desired value. Similar actions are performed for the freezer, where the snowflake symbol with stars is often used.
⚠️ Attention: In some models, a sound signal is heard when the settings are changed. If it does not stop, the button may be pressed for too long or a sensor error has been recorded in the system.
Electronic control allows you to implement the function Super Cool or Super Freeze. When these modes are activated, the refrigerator operates at maximum capacity for a limited time (usually a few hours), after which it automatically returns to the previously set user settings. This is convenient before guests arrive or after a large purchase of groceries.
Optimal temperature conditions
To ensure maximum freshness of products and the safety of their consumption, it is necessary to comply with the recommended temperature ranges. In the refrigerator compartment, the ideal value is +4°C. At this temperature, most bacteria slow down their activity, but the food does not freeze.
In the freezer, the standard is -18°C. It is at this temperature that products can be stored for up to 12 months without loss of taste and vitamin composition. Lower values (-24°C) make sense only in fast freezing mode, but constantly maintaining such cold is impractical in terms of energy consumption.
| Product type | Recommended zone | Optimal temperature | Shelf life (approximate) |
|---|---|---|---|
| Meat and fish (chilled) | Lower shelf / Freshness zone | 0...+2°C | 1-3 days |
| Dairy products | Middle shelves | +2...+4°C | 3-7 days |
| Vegetables and fruits | Bottom drawers | +5...+8°C | 3-10 days |
| Ready meals | Upper shelves | +3...+5°C | 1-2 days |
It is worth remembering that the distribution of cold in the chamber is uneven. It is always colder at the back wall, where the evaporator is located. Closer to the door, the temperature may be 2-3 degrees higher. Place products taking into account this feature: perishable goods - in the back, and drinks and sauces - on the door shelves.
Special modes: Vacation and Fast freezing
Many owners Helkama do not use the full potential of their devices, ignoring special modes. The Holiday function is designed for long trips. When activated, the temperature in the refrigerator compartment rises to +14...+15°C. This prevents the appearance of mold and unpleasant odors in an empty refrigerator, while the freezer continues to operate as normal.
The “Super Freeze” mode is indispensable when you need to preserve the maximum benefit in fresh berries or meat. When this mode is turned on, the compressor operates continuously, freezing food as quickly as possible, which prevents the formation of large ice crystals that destroy the cellular structure.
- 🏖️ Vacation mode: Saves energy, prevents odor, while keeping the freezer active.
- 🧊 Quick freezing: Requires manual shutdown after 24 hours in models without auto-timer.
- 🍺 Mini Bar mode: In some models, it allows you to turn off the freezer completely, turning the refrigerator into a drink cooler.
Using these functions requires an understanding of their purpose. For example, turning on the fast freezing mode in an already fully loaded freezer can lead to previously frozen food starting to thaw due to a disruption in heat exchange before the temperature drops again.
Why can’t fresh food be stored in vacation mode?
A temperature of +15°C is safe for an empty chamber, since it is above the threshold for active reproduction of many bacteria, but this is not enough for fresh food - they will begin to deteriorate within a few hours.
Diagnostics of temperature problems
If you notice that the refrigerator Helkama has ceased to maintain the temperature properly, do not rush to call a technician. Often the problem lies in improper operation or external factors. First of all, check the tightness of the sealing rubber bands. If the door does not close tightly, warm air comes in and the compressor cannot cope.
The second common reason is the location of the refrigerator. If it stands close to the wall or next to (battery, stove), heat exchange is disrupted. For normal operation, the rear radiator grille requires free air flow. Also check whether the ventilation holes inside the chamber are not blocked by food.
⚠️ Attention: If a “coat” of ice has formed on the back wall of the refrigerator compartment, and the food below is freezing, you may have turned the thermostat too far or the defrost sensor is faulty.
In models with system No Frost temperature problems may be associated with a clogged drain hole. The water stops flowing, freezes and blocks the cold air circulation channels. Cleaning the drainage with a special brush or soft wire often solves the problem without repair.
☑️ Check before calling a technician
Frequently asked questions (FAQ)
Why a refrigerator Helkama is loud after setting the temperature?
After changing the settings, especially to lower values, the compressor starts working harder to achieve the set parameter. This is fine. If the noise does not subside after 5-6 hours of operation or is accompanied by vibration, check whether the refrigerator is level (adjust the legs) and whether the pipes are touching the back of the wall.
What temperature should be set in the summer, if the apartment is hot?
In the summer, when the room temperature is high, the refrigerator requires more effort to cool. It is recommended to set the thermostat to a slightly above average value (for example, 3 out of 5), but not to the maximum. Maximum load in summer can lead to overheating of the compressor. Also make sure that the refrigerator is not placed in direct sunlight.
What to do if the refrigerator compartment is +10°C, although it is set to +4°C?
First, let the refrigerator operate without opening the doors for 24 hours. If the temperature does not drop, check the operation of the fan (if you can hear it) and the cleanliness of the condenser at the back. If the technical parameters are normal, there may be a freon leak or a malfunction of the thermostat/sensor, which requires specialist intervention.
Is it possible to turn off the fast freezing mode ahead of time?
Yes, you can. If you see that the food is already frozen, the mode Super Freeze can be turned off manually by pressing the corresponding button. This will help save energy and avoid unnecessary load on the unit. In some models, this mode turns off automatically after 24-48 hours.
