Two-chamber refrigerators Indesit with system No Frost have earned popularity due to their reliability and the absence of the need for regular defrosting. However, even time-tested equipment may require intervention from the owner to operate correctly. Incorrect temperature settings or incorrect position of the housing often cause poor cooling or excessive noise.
Many users are faced with a situation where food in the main chamber begins to freeze, but in the freezer, on the contrary, it is not cold enough. In other cases, the device begins to hum or knock when the compressor is running. Adjusting the refrigerator is a set of measures that includes setting the level, adjusting the thermostat and checking the air dampers. Understanding these processes will help you avoid calling a technician and extend the life of the unit.
In this article we will look at all the nuances of setting up two-chamber models Indesit. You will learn how to correctly position the legs, where the temperature regulator is located and what to do if the system No Frost is malfunctioning. Proper initial setup is the key to ensuring that the equipment will operate silently and economically for many years.
Diagnostics before starting adjustment
Before you take a screwdriver or turn the controls, you need to understand what exactly is not working correctly. Often the problem lies not in a breakdown, but in a banal violation of operating or installation rules. Two-chamber refrigerator This is a complex mechanism where the freezer and refrigerator compartments may have different temperature requirements.
Pay attention to the nature of the noise. If the hum is uniform and quiet, this is normal operation of the compressor and fans. If knocking, rattling or whistling is heard, the installation needs to be checked. Also check that the doors fit tightly to the cabinet. The gap may be invisible to the eye, but sufficient to allow warm air to enter.
⚠️ Attention: If you notice that the back wall in the refrigerator compartment is covered with a thick layer of ice (“fur coat”), and the food is spoiling, this may indicate a malfunction of the defrost system or a freon leak, and not the need for simple adjustment.
First, conduct a visual inspection. Make sure there is a gap of at least 5-7 cm between the back wall of the refrigerator and the kitchen wall for ventilation. Check whether the chamber is overloaded with products, as this blocks the circulation of cold air, which is critical for the system No Frost.
Adjusting the position of the body and legs
The first step in setting up is always leveling the device. If the refrigerator is not level, the door may not close on its own, and the compressor will operate with increased vibration. The model Indesit is usually equipped with adjustable support screws in the front.
To adjust, you will need a level or just a visual assessment. The tilt of the body should be minimal back so that the door closes itself if it is opened 45 degrees. This ensures tightness and prevents ice from freezing on the seal.
Use the following algorithm:
- 🔧 Loosen the lock nut on the support leg, if present, or simply rotate the leg itself with a wrench.
- 🔧 Rotate the front supports clockwise to raising the corner or against it to lower it.
- 🔧 Achieve a position where the top edge of the refrigerator is parallel to the floor, and the body itself is slightly tilted back.
- 🔧 Check the stability: the device should not wobble when you lightly press the corner.
After adjustment, be sure to check the operation of the door. It should open smoothly, without jerking, and fit snugly around the entire perimeter. If the distortion remains, repeat the procedure, paying attention to the diagonals.
Setting the temperature mode
B two-chamber refrigerators Indesit temperature control can be carried out by a mechanical thermostat or an electronic panel. In mechanical models, inside the main chamber there is a knob with divisions from 1 to 5 (or Min to Max). It is important to understand: the number does not indicate degrees, but cooling intensity.
The higher the number on the regulator, the colder it will be in the chamber. For normal storage of food in the refrigerator compartment, it is recommended to set the handle to position 2 or 3. This corresponds to a temperature of about +4...+5°C. Setting it to maximum (5 or Max) results in icing of food and increased load on the compressor.
The temperature in the freezer should be maintained at -18°C. If your model has a separate control for the freezer (often located inside it or on the panel), it should also be set to the middle position. The system No Frost will distribute cold air itself if the dampers are working properly.
| Regulator position | Operating mode | Temperature range (approximate) | Recommendation |
|---|---|---|---|
| 1 (Min) | Minimum cooling | +6...+8°C | Summer, small quantities of food |
| 2-3 | Normal mode | +3...+5°C | Daily use |
| 4-5 (Max) | Maximum cooling | 0...+2°C | Large volume loading food |
If you have just turned on the refrigerator or loaded it with a large amount of warm food, you can temporarily move the regulator to position 4 or 5 for rapid cooling. However, after 6-8 hours, be sure to return it to normal mode 2-3.
Why can’t you keep the regulator at maximum all the time?
Constant operation at maximum power leads to the fact that the compressor does not turn off. This causes overheating of the motor, increased energy consumption and reduces the life of the No Frost system.
Adjusting the air damper (Damper)
In two-chamber refrigerators with the system No Frost cold enters the upper chamber from the freezer through a special channel. The air flow is regulated by a damper. If it is too cold in the refrigerator compartment and food freezes at the back wall, it is possible that the damper does not close completely or its calibration is lost.
On some models Indesit manual adjustment of the damper position is available. It is usually located at the top of the back wall of the refrigerator compartment or hidden behind a plastic panel. Before intervention, be sure to unplug the device!
⚠️ Attention: Plastic becomes brittle at low temperatures. If you decide to remove the panel to access the damper, let the refrigerator stand turned off for 15-20 minutes at room temperature so that the plastic “warms up.”
The adjustment mechanism may look like a screw or a slider with markings. Turning the screw clockwise usually closes the damper, reducing the flow of cold air into the main chamber. Proceed very carefully, turning no more than 1/4 turn at a time.
After adjustment, turn on the refrigerator and let it run for a day. Measure the temperature with a thermometer placed in a glass of water in the middle of the chamber. This is the only way to objectively assess the effectiveness of the setting.
Eliminating problems with the No Frost system
The No Frost system (or Full No Frost) involves automatic defrosting of the evaporator. If you notice that ice has appeared in the chamber, although there was none before, this may be due to a lack of air circulation. Often the reason lies in the fact that the products are pushed close to the back wall.
The fan driving the air should freely wash all the products. If flow is blocked, the sensors may not read the temperature correctly and the compressor will run longer than necessary. Free up space at the back wall by at least 3-5 cm.
☑️ Checking the No Frost system
It is also worth checking the condition of the door seal. If it is dirty or deformed, moist air from the kitchen enters the chamber. In the system No Frost this moisture quickly turns into an ice crust on the evaporator, which the standard heater may not have time to melt.
If ice forms only in one corner or in the lower part of the chamber, this is a sure sign of a leak or a malfunction of the defrost. In this case, simple adjustment may not help, and diagnostics of the heating element or defrost timer will be required.
Common mistakes when setting it up yourself
When trying to “improve” the operation of the refrigerator, users often make mistakes that lead to the opposite effect. For example, setting the regulator to maximum in the hope of cooling food faster. This leads to freezing of vegetables and fruits, which lose their properties.
Another common mistake is ignoring the floor level. If the refrigerator is tilted forward, the door will constantly strive to open, and the seal will quickly wear out. This leads to the constant entry of warm air and the formation of a “fur coat”.
You should also not change the thermostat settings often. The refrigerator takes time (from 6 to 24 hours) to stabilize the temperature after changing the position of the handle. Frequent switching disrupts the operating algorithms of the electronics (if any) and wears out the mechanics.
Prevention and care after adjustment
After you have successfully adjusted the position of the legs and set the temperature, it is important to consolidate the result. Check regularly to see if the settings have changed. Once every six months, wipe the rubber seals and check the cleanliness of the condenser at the back (if it is an open type).
Watch how the refrigerator reacts to changing seasons. In the summer, when the apartment is hot, a slightly more intensive operating mode (closer to 3-4) may be required, and in the winter, when the room is cool, position 2 is sufficient. However, modern models Indesit usually adapt to the climate class themselves.
Following simple operating rules will allow you to forget about problems with cooling. If after all the adjustments the problem persists, most likely there is a technical malfunction that requires replacement of parts.
How often does No Frost need to be defrosted?
Technically, the No Frost system does not require defrosting. However, manufacturers recommend that once a year (or if an odor appears) completely turn off the refrigerator for 24 hours for hygienic cleaning and removal of bacteria that may have accumulated in the drainage system.
FAQ: Frequently Asked Questions
Why does food freeze at the back wall in the Indesit refrigerator compartment?
This can happen for three reasons: the temperature regulator is turned to maximum (4-5), the food touches the back wall, blocking the exit of cold air, or the air damper is faulty, which supplies too much cold from the freezer.
What is the normal temperature in a two-chamber refrigerator?
Optimal temperature in the main one chamber is between +2°C and +5°C. The temperature in the freezer should not exceed -18°C. To check, use a regular outdoor thermometer placed in a glass of water.
Is it possible to adjust the legs without turning off the refrigerator?
Yes, you can adjust the support screws while the compressor is running. The main thing is to do this carefully so as not to tip the unit over and damage the floor. However, to access some elements of the damper adjustment, it may be necessary to turn it off.
What should you do if, after adjustment, the refrigerator begins to make noise?
Check whether the cabinet is vibrating against the wall or furniture. Make sure all shipping bolts (if any were on the compressor) have been removed. If noise appears after adjusting the legs, you may have warped the case and the compressor is touching the internal elements - level the device.
