What is Know Frost?

Samsung refrigerators “Nou Frost” differ from “counterparts” with a conventional cooling system in that the freezer itself does not have the usual evaporator made of metal on which products for freezing are laid.


The device of the refrigerator Nou Frost has such features:

  1. The evaporator in such models is taken out of the chamber, which creates cold, into the case of the back wall and is hidden behind plastic panels.

Important! This technology is also called defrosting windy type.

  1. Food in this type of refrigerator is cooled by the cold air circulating through the chambers passing through the evaporator, which is more correctly called an air cooler.
  2. The evaporator itself is reminiscent of a car radiator in design.
  3. In various models of devices, the air cooler can be located both in the upper and lower parts of the freezer, or behind the panel on the rear wall of this chamber.
  4. Refrigerators with the Nou Frost system have an additional fan, which is installed behind the evaporator.

Important! It is a fan that takes air from the freezer and refrigerator, and then drives it through the evaporator. Passing through the evaporator, the air is cooled to a certain temperature. Then, through a system of channels, sent to products.

  1. Most of the cold air enters the freezer, and the rest, through an additional channel, goes to the refrigerator.
  2. Contrary to the name of the “Nou Frost” system, which translates as “without hoarfrost,” moisture nevertheless settles, but not on the walls, but on an evaporator closed to the eyes. Once every 8-16 hours, the frost is thawed by the heating elements located under the evaporator.
  3. A defrost command is issued by a mechanical or electronic timer. Therefore, thanks to this technology, you can clean the refrigerator inside once a year. This facilitates the maintenance of the unit and saves the time of the owner of the “miracle technology”.

How does defrosting work?

Without periodic defrosting, refrigerators simply could not function. To understand how this process takes place in the Samsung Nou Frost refrigerator, we will familiarize ourselves with the standard procedure for this action:

  1. After a certain time (10-14 hours), having counted the freezing cycle, the timer makes the opening of some contacts and the closure of others.
  2. In this case, the power supply circuit of the fan and compressor is broken, the heaters turn on.
  3. As a result, the temperature on the surface of the evaporator rises, and the frost starts to thaw from it, and the melt water begins to drain through a tube into a special container located on the back of the freezer, on the compressor casing.
  4. Since the compressor heats up during operation, the water evaporates over time.

Important! Manually refrigerators with the Nou Frost system are not defrosted, only a one-time disconnection of the device from the mains is allowed once a year - for washing cameras and their parts.  

Advantages of Samsung Nou Frost

Refrigerators with an automatic defrosting system from Samsung manufacturer have the following advantages and advantages:

  1. The temperature is distributed evenly.
  2. The necessary storage conditions for products are quickly recreated with a large load or frequent opening of the door.
  3. Multi-threaded cooling system. Cold air through the openings located on each shelf effectively and evenly cools products.
  4. High-quality thermal insulation.
  5. The presence of a digital display allows you to set the required temperature - both in the freezer and in the refrigerator compartment.
  6. Protected container. While maintaining a low temperature in a protected container, the products are ideally stored, in addition, medicines in such a container will be inaccessible to children.
  7. Save time and effort in defrosting the refrigerator.
  8. Vegetables and fruits remain fresh for a very long time.

Important! Please note that the proper operation of the equipment is affected by its proper connection, therefore, we recommend that you find out information about how to install a refrigerator.

Disadvantages of Know Frost

Refrigerators “Nou Frost” have one feature that must be borne in mind: since air blowing of products occurs inside the device, this leads to their dehydration and airing.

Important! All products in this type of refrigerator must be stored in packages.

The technology provided has a number of disadvantages:

  1. High noise level.
  2. Part of the volume of the camera is embedded equipment.
  3. Increased energy costs.
  4. The price of the device is higher than the drip version.

Evaporator thermal relay defect

A sign of such a malfunction is the frost on the evaporator. For 2-3 days of such a breakdown, the evaporator will be completely covered with a snow layer and the refrigerator will stop freezing due to the temperature increase in the chambers. The compressor in this case will stop turning off by the thermostat.

Other breakdowns

Due to mechanical damage to components, for various reasons, such breakdowns occur:

Improper operation can lead to such problems:

  1. Clogged capillary line.
  2. Dehumidifier filter clogged.

Less common failures include:

  1. Open compressor winding.
  2. Jamming of the compressor motor and, as a result, lack of engine rotation.
  3. Defective evaporator blower fan. The first sign of such a malfunction is the absence of fan noise and an increase in temperature in the chambers.

Important! In all these cases, it is better to contact the Samsung service center.
