Not freezing is a common problem when using a refrigerator for a long time. Let's find out the causes and how to handle it when the refrigerator does not freeze in the article below!
Power supply
The first thing you need to do is check the power supply to the refrigerator.
Reason
How to handle
Refrigerator door does not close properly or gasket is broken
A loose refrigerator door is sometimes the simple reason why the refrigerator is not freezing or making ice.
Main cause
How to handle
The temperature control knob or air flow control knob is in the wrong position.
Refrigerators usually have 2 control buttons : temperature adjustment in the refrigerator compartment and air flow adjustment in the freezer compartment.
Reason
Many people mistakenly think that the control knob only works for the refrigerator compartment, so they adjust it down. As a result, the refrigerator does not freeze.
How to handle
Blocked cold air duct to the refrigerator compartment
The refrigerator's cool compartment is cold because there is a pipe that leads cold air down there.
Reason
When the evaporator is frozen or the vents in the refrigerator compartment are frozen or covered by food, the cold air duct will be blocked and not cold.
How to handle
The defrost system is not working, causing the evaporator to freeze.
The refrigerator defroster is very important. When the defroster is not working, it will cause the evaporator to freeze. A frozen evaporator is one of the very common reasons to answer the question of why the refrigerator is not freezing.
The evaporator is the part that receives the cold temperature of -18 degrees Celsius from the gas inside the copper pipes of the evaporator. Then, the fan will blow cold air from the evaporator into the refrigerator compartment to bring the refrigerator compartment back to -18 degrees Celsius. Part of the cold air will be sent to the refrigerator compartment to cool the food.
Thus, if the evaporator is frozen, the temperature will not reach -18 degrees Celsius and will hinder the circulation of cold air.
How to handle
The timer is broken, causing the evaporator to freeze.
The timer (also known as a time relay) is a device located inside the temperature control box in the refrigerator compartment. It is responsible for turning the refrigerator and the defrost unit on and off. When the relay is broken, the defrost unit will not work, causing the evaporator to freeze. As a result, the refrigerator will not freeze ice or it will take a long time to make ice.
How to handle
Fan
1. Damaged
When the fan is broken, cold air from the evaporator will not be transmitted to the freezer and refrigerator compartments, so the refrigerator will not be cold and the ice will not freeze.
How to check
2. Fan running in reverse
This case is quite rare in newly purchased refrigerators. The reason is that when repairing, the technician wired the fan in reverse, causing the fan to "spin backwards". Instead of blowing cold air from the evaporator to the 2 compartments of the refrigerator and freezer, the fan "sucks" air from the freezer into the evaporator, causing the refrigerator not to cool.
How to check
How to handle
Out of gas or low on gas
Gas is an important medium in the cooling process. When the refrigerator runs out of gas or lacks gas, it will cause the refrigerator to freeze slowly, the cooling time will be prolonged...
How to handle
Refrigerator block is broken
The refrigerator block (also known as the refrigerator compressor) is the main part, the “heart” of the refrigeration system. The block helps pump compressed gas into the condenser and recover gas from the evaporator. A damaged or weak refrigerator block is one of the reasons why the refrigerator does not freeze.
In addition, when the cooling fan is damaged, it can cause the refrigerator block to be damaged. Therefore, it is necessary to check both to completely fix the problem of the refrigerator not freezing.
How to handle
The above article has fully and detailedly summarized the reasons why the refrigerator cannot freeze and how to handle them. Hopefully you have found the cause and how to fix it if your refrigerator does not freeze.
