The advanced defrosting systems features

A couple of decades ago, each housekeeper knew that it is necessary to defrost and clean the refrigerator at least once a month. Nowadays this is not necessary because almost every refrigerator is equipped with the No Frost technology, that is, an automatic defrosting system. However, it is impossible to completely forget about manual defrosting. Toronto appliance repair specialists advise doing it 1-2 times a year to avoid the fridge doesn’t work properly.

The causes of frost

The reasons for the formation of frost on the walls of the refrigerator compartment are worth understanding. They are numerous but the following are considered the main ones:

  • Excessive moisture. Condensation forms on the walls of the refrigerator compartment. Later it is converted into a snow cover. Initially, it visually looks like a kind of crystals but over time they increase in volume.
  • The presence of unpackaged products of plant origin and liquids in the refrigerator. This leads to an increase in the level of air humidity and temperature, which, as a result, causes condensation.
  • Long-term operation without defrosting. In such a situation, a small layer of frost becomes an ice armor which often becomes the cause of further fridge breakdown. And when you try defrosting it manually you will face a meltwater tsunami. In this case, calling fridge repair services in Toronto is the best solution.

The advanced frost free technologies

Today, the electrical engineering market is filled with a variety of refrigeration units.  Almost all of them, regardless of size and functionality, are equipped with automatic defrosting systems. They can be divided into 2 main subtypes:

  • manual and automatic No Frost for the freezer compartment;
  • automatic drip and automatic No Frost for the refrigerator compartment.

These automatic defrosting systems are a true relief for the housekeepers saving them from monthly headaches due to frost formation. Today on the market there is a rather impressive range of refrigeration units that are equipped with several defrosting systems: manual, drip, and No Frost.

No Frost systems pros and cons


  • no frost;
  • uniform temperature distribution over the entire area of the refrigerator compartment;
  • rapid recovery of the temperature regime after a long opening of the chamber;
  • the possibility of buying a combined type refrigerator ( No Frost in the freezer compartment, and a drip system in the refrigerator);
  • versatility (in contrast to drip defrosting, the No Frost system can be installed both in the refrigerating compartment and the freezer).


  • a decrease of humidity inside the chamber leads to drying of many products;
  • high power consumption;
  • increased noise level (in some models);
  • high cost compared to a refrigerator equipped with a drip system;
  • less capacious due to the presence of a rather dimensional evaporator mechanism in the chamber.

Drip defrosting systems pros and cons


  • low cost;
  • simple design;
  • efficiency;
  • simplicity and low cost of fridge repair;
  • autonomy and reliability.


  • limited use (works only in the refrigerator compartment, does not apply to the freezer);
  • long defrosting time,
  • a complete shutdown of the fridge (however, some systems can perform defrosting without deactivating general activity).

Therefore, when choosing a refrigeration unit with a No Frost or drip defrosting system, first of all, think about the criteria the refrigerator should meet. Then analyze the above material given to you by our trained appliance repair professionals and make the right choice.
