Correct setting of refrigeration equipment immediately after delivery is not just a formality, but a necessary condition for long and stable operation of the compressor. Many owners of new equipment make the mistake of plugging the unit into the network instantly, which can lead to failure of the cooling system due to improper distribution of oil in the circuit. For brand models Medline, like any other modern equipment, a period of adaptation to the room temperature is required before the first start.
During operation, you may encounter the need to change the temperature regime or activate the quick freezing function. Understanding the operating principles of thermostat and the refrigerant circulation system will help you avoid food spoilage and excessive energy consumption. In this material, we will analyze in detail all the stages of setting up the thermostat
Please note that the interfaces of the control panels may differ depending on the specific series and year of manufacture of your device. If you notice a discrepancy between buttons or symbols, check the paper manual included in the kit, as manufacturers often update the software and appearance of the panels.
Primary preparation and settling time
The first and most critical stage is the correct positioning of the unit in space. The refrigerator must stand strictly horizontally, which is checked by the building level. The legs are adjustable in height so that the doors close tightly under their own weight, but without distortion. If the device stands crooked, compressor it will operate with increased vibration and noise.
There is a golden rule regarding the waiting time before turning on. If transportation was carried out in a vertical position, it is enough to let the equipment stand for 2–3 hours. However, if the device was lying on its side, the waiting time increases to 8–12 hours. This is necessary for the oil to drain into the compressor crankcase.
⚠️ Attention: It is strictly forbidden to plug in the device if it has just been brought in from the cold. A sharp change in temperature indoors and on the motor windings can cause condensation, which will lead to a short circuit or damage to the insulation.After the device has settled, it is necessary to carry out initial hygienic treatment. Wipe the interior shelves and drawers with a soft cloth using a weak solution of baking soda or a special household appliance cleaner. This will remove factory dust and foreign plastic odors.
☑️ Check before first start
Done: 0 / 5Adjusting the temperature
The main task of the user is to set the optimal temperature for storing food. In refrigerators Medline this parameter is regulated either by a mechanical thermostat or an electronic control panel. The standard temperature for the refrigerator compartment is considered to be from +3 to +5 degrees Celsius.
If you have an electronically controlled model, the settings are made by pressing the buttons on the display. Digital values are displayed in real time. It is important to understand that changing the settings does not happen instantly - the system takes from 2 to 4 hours to stabilize the climate inside the chambers after your intervention.
For the freezer, the optimal value is -18 degrees. Lower temperatures have no practical meaning for normal food storage and only increase the load on unit. Increasing the temperature to -12 or -6 degrees is allowed only for a short period if you plan to use supplies in the coming days.
It is not recommended to open the doors frequently during the first day of operation, especially if the chamber is loaded with room temperature products. This will allow the system to quickly reach the set mode and form the necessary supply of cold in the evaporator.
Using the Super Freeze and Super Cool functions
Modern models are often equipped with accelerated cooling modes. The function Super Cool (Super cooling) is designed to quickly reduce the temperature in the refrigerator compartment. This is true when you have just returned from the store with a large amount of food that needs to be cooled urgently without increasing the overall temperature in the chamber.
Mode Super Freeze (Super Freeze) activates continuous operation of the compressor in the freezer. This is necessary when loading a large volume of fresh, non-frozen food. Intensive freezing allows you to preserve the cell structure of products, vitamins and taste, preventing the formation of large ice crystals.
- 🔹 Activate the mode 4-5 hours before loading products to achieve maximum effect.
- 🔹 Do not keep the function turned on for more than 24-48 hours, so as not to overload the motor resource.
- 🔹 After automatically or manually turning off the mode, give the system 3-4 hours to return to its normal operating rhythm.
In some modifications, these functions are turned off automatically after a specified period of time, in others they require manual shutdown. Follow the display on the panel to prevent the engine from operating in extreme mode unnecessarily.

The efficiency of the refrigerator directly depends on how you place the products. The circulation of cold air should not be difficult. If you pack the shelves tightly to the top, blocking the ventilation holes, the sensors will show incorrect data and the compressor will run without interruption.
There are certain cold zones inside the chamber. The coldest places are at the back wall and on the lower shelves (usually around 0...+2 °C). This is the best place to store meat, fish, dairy products and open packages. On the middle shelves the temperature is slightly higher (+3...+5 °C), which is ideal for ready-made dishes, sausages and cheeses.
Storage area Temperature conditions Recommended products Shelf life (approximate) Bottom shelf / Freshness zone 0...+2 °C Raw meat, fish, minced meat, open milk 1-3 days Middle shelves +3...+5 °C Ready meals, sausages, cheeses, eggs 3-5 days Door shelves +5...+8 °C Sauces, drinks, canned food, oil By expiration date Boxes for vegetables +8...+10 °C Fruits, vegetables, greens 5-10 days Door shelves are the warmest place due to constant contact with warm air when opening. Do not put perishable products there, such as milk or eggs (although many manufacturers equip refrigerators with trays for eggs in the doors, this is not the best place for long-term storage).
No Frost setting and humidity control
Technology No Frost (No frost) eliminates the need for the user to defrost the refrigerator manually. The system automatically removes moisture and prevents the formation of ice crust. However, it is important for owners of such models to know about the nuances of the system's operation.
In refrigerators with No Frost the air inside the chambers is drier than in drip systems. This can lead to rapid weathering of products if they are not packaged. Be sure to use containers with lids or cling film for storing vegetables, fruits and prepared foods.
Particular attention should be paid to the dampers that regulate the flow of cold air. Some models Medline have the ability to mechanically or electronically regulate the air flow between the chambers or inside the refrigerator compartment. If you notice that food in the freshness zone is freezing, try reducing the flow intensity.
⚠️ Attention: Do not seal the ventilation holes inside the chamber, even if they seem to you to be sources of excess cold. Blocking the air ducts will lead to local overheating of the evaporator and system breakdown No Frost.Why does meat dry in No Frost?
Dry air in the No Frost system intensively evaporates moisture from the surface of the products. Unlike the drip system, where the humidity is higher, here packaging is mandatory. If meat is stored open, it will lose up to 10% of its weight per day simply due to the evaporation of moisture.
Diagnostics and troubleshooting
During operation, situations may arise that require your intervention. Users often confuse normal operation of equipment with a malfunction. For example, noise when the compressor operates or clicks when switching modes are normal phenomena for most models.
If the refrigerator starts working continuously without turning off, check the tightness of the door seals. Falling crumbs or a skewed door can break the seal, causing warm air to constantly flow inside, causing the motor to wear out.
- 🔹 The appearance of a puddle under the refrigerator may indicate a clogged drainage hole. Clean it with a special brush or soft wire.
- 🔹 A strong hum often occurs if the refrigerator is too close to the wall or furniture. Maintain a gap of at least 5-10 cm from the back wall.
- 🔹 If ice forms on the walls of the refrigerator compartment (not No Frost), the temperature setting may be set too low.
Models with electronic control are characterized by error codes that may appear on the display. The decoding of a specific code (for example, F1, E2) should be found in the instructions for your specific model, since they may differ between different manufacturers and series.
What to do if the light goes out, but there is cold?
Most often the light bulb burns out. However, if the refrigerator has stopped freezing and there is no light, check to see if the power light is on. There may be a problem with the wire or socket. If the indicator is on but there is no light, it is a lamp. If nothing lights up, there is an electrical problem.
How long should the Medline refrigerator work for the first time?
The first cycle of operation can last longer than usual, from 6 to 12 hours, until the chambers cool down to the set temperatures. After this, the device should go into standby mode (turn off). If it works for a day without a break, check the settings and the tightness of the doors.
Why do the side walls of the refrigerator get hot?
In modern models, the condenser (heat exchanger) is often built into the side walls. Their heating to 40-50 degrees in the first hours of operation or during active freezing is a normal physical process of heat removal.
Is it possible to install a Medline refrigerator in an unheated country house?
Most household refrigerators are designed to operate at ambient temperatures from +10 to +32 degrees. Operation at lower temperatures may cause the oil in the compressor to solidify and cause the thermostat to malfunction. Check the climate class of your model in the passport.
How often do you need to defrost a refrigerator with the No Frost system?
The No Frost system does not require regular defrosting to remove ice. However, hygienic defrosting and washing are recommended to be carried out 1-2 times a year to remove bacteria and odors that the moisture removal system cannot eliminate.
What does a flashing temperature indicator mean?
A flashing indicator usually signals that the temperature inside the chamber is above normal. This can happen immediately after switching on, after loading warm food, or when the door is not tightly closed. If the blinking continues for more than 24 hours in normal mode, contact the service.
