The most important electrical appliance in the kitchen is the refrigerator, and without it, life becomes very difficult today. For a shop and home refrigerator to function properly, its parts must be intact and repaired quickly
In the event of a malfunction. One of the important parts of the refrigerator is the heating element. Fault in the refrigerator heater element, as mold collects on the pipes located behind the refrigerator and causes the refrigerator to malfunction. Given the importance of this part, as soon as any signs of damage appear, you should head to a repair technician to repair the heater element.
What is a refrigerator heater element?
Heater means heater. It may be surprising that a refrigerator is a cooling device, but what is the role of the heater and what is its use? In old refrigerators, frost was constantly forming in the parts of the freezer and refrigerator, and to remove the frost, the refrigerator was separated and the frost was cleaned. Today’s refrigerators, which include the Urbano brand, are equipped with a frost prevention system that prevents frost. . The frost formed in this type of refrigerator is one of the frosts that form in the evaporator, and the presence of this frost causes serious damage to the refrigerator. When frost forms on the evaporator, it causes the frost to freeze and causes the refrigerant gas passing through these tubes to not work properly, as a result of which the performance of your Urbano refrigerator is affected.
Of course, it should be noted that the frost that forms on the evaporator is normal and this is due to the fact that we constantly open and close the refrigerator door, and thus the heat present in the external environment enters and exits the refrigerator. It disturbs the thermal balance, as this compressor takes heat from the refrigerator and creates cold. The lost heat turns into frost on the evaporator. This frost must be melted by the heater element so that the refrigerator can perform the cooling process properly.
Application of heater element in refrigerator
There are different types of heater elements, and depending on the make and model of your refrigerator, any of them can be used. Different models of heater element are metal rod type, aluminum rod (covered with aluminum tape) and wire inside glass tube. The task of the heater element in NoFrost refrigerators is to control the thermal disc, electronic board parts and perform the defrosting process. The heater elements in different refrigerators have different thicknesses and lengths, and refrigerators with larger capacity have stronger compressors, and their heater elements also have higher capacity. The heater elements are installed at the back of the refrigerator and are easily accessible in case the heater element in the refrigerator malfunctions.

Symptoms of a malfunctioning refrigerator heater element
If the heater elements are damaged, the following problems will appear for the refrigerator.
The refrigerator is overcooling or the appliance is not cooling
Overcooling and not cooling the refrigerator are symptoms of a damaged heater element, but it can vary depending on the damage to the heater element. If the refrigerator is on and running, but is not producing cold and does not reach the set temperature, the cause may be a burnt out heater element and failure of the heater element in the refrigerator.
Refrigerator Freezer Operator
If the refrigerator operators freeze due to damage to the heater elements, the refrigerator will not be able to reach the set temperature. To check this, take a look at the actuator located at the back of the freezer wall. If ice forms on the actuator, the heater elements are likely damaged or burned out.
The back of the refrigerator is not warm
The back of the refrigerator is always emitting some heat. If the heating elements are not working properly, you will not notice any heat from the back of the refrigerator.
How to test a refrigerator heater element
If you see signs of heater element failure in your upright refrigerator, you may want to test the heater element. To test the heater element, do the following steps:
Find the heater element
Remove obstructions such as shelves, drawers, and food items
Remove the screws
Remove the heating element
Check this with a multimeter or multimeter tester
If you see zero or infinity on the multitester, the heater element must be replaced quickly
If the resistance of 600 remains constant on the multimeter, then the heater element is broken. The resistance of the sanitary heater element ranges from 100 to 500.
What factors cause refrigerator heater element failure?
The following factors are effective in damaging and burning the refrigerator heater element:
Water does not reach the element
The refrigerator ran out of gas
Refrigerator compressor failure
Excessive opening in the refrigerator
Rotting and torn gaskets in the refrigerator
Replace the heater element
To change the heating element in a branded refrigerator, do not act arbitrarily and that is why be sure to hire an expert. To replace the heater element, you must first disconnect the refrigerator from electricity and empty the contents inside the freezer. After that, the repairman must open the screws and clips through which the heater is connected to the refrigerator and release the panel. Then the specialist connects the heater element wires, pulls out the heater and separates it from the refrigerator. Place the new heater in the previous place and tighten its screws and clips. The important thing to remember is that due to the sensitivity and expensiveness of the refrigerator, if you see any signs of a broken heater element, do not leave the repairs to inexperienced people and seek out a professional repairman. This will prevent additional costs and further damage.
Maybe your refrigerator doesn’t have a heater element?
Yes, some refrigerators defrost and defrost automatically without the need for a heating element. This is done in such a way that the refrigerant cycle is reversed with the help of solenoid valve and this process takes place. In this type of refrigerator, in addition to producing ice and frost, gas also melts them. These refrigerator models have very high energy consumption and must be constantly checked and repaired.
