Do you feel you have entered to the pole when you open the door of the refrigerator? Have your drinks become to ice in heaven? Have your vegetables wither due to frostbite? Do you want to know why your refrigerator is too cold?
Sometime the refrigerators do not work good and bring extremely cold! To the extent they force us to tell them very frankly: “Please don’t trouble yourself, my work goes well with less cold!”
But since talking to the refrigerator is useless, we, on the RepairLand website, decided to prepare a post about the reason of the low temperature of the refrigerator so that you can find the problem of it in a principle way.
Which part of the refrigerator does cause it to be too cold?
If you want to find the cause of your refrigerator freezing, the reasons can be one of the following things:
- Air inlet damper
- Thermistor or temperature sensor
- Main board
- Temperature control board
The malfunction of one of above components can be the cause of extreme cold in the refrigerator. Do not worry, it is not supposed to be content with these brief explanations; in the following we will talk in more detail about the performance of each of these components.
How does the air inlet damper problem generate too much cold?
How do you feel when you bite a frozen peach? Yes, of course, it is not pleasant! So if, after such an unpleasant experience, you are looking for the cause of your refrigerator shelf freezing, you must become acquainted with air inlet damper.
It is one of the important components of the refrigerator that balances air flow of the operator fan. The performance of this component causes the poppet valve (flapper) to be controlled. The air damper controls the amount of cold air entering the interior space of the refrigerator.
So, if the air temperature of your refrigerator drops and all your food freezes, you should check the flapper and its control handle.
Since this damper works mechanically, you must move the control handle slightly to check it to make sure that it moves freely, otherwise the damper has a problem and you must replace it.
Be careful not to damage the damper during inspection or replacement, because this component is usually made of plastic or has a polystyrene coating. It is easily damaged.
It is noted that sometimes, in some refrigerators, a piece called a measuring bubble regulates the temperature. If your refrigerator has it, be sure to check it and make sure not to be damaged and to be in its right place.
Is the extreme cold problem related to the main board?
One of the common questions of users is why a refrigerator freezes? If you are also trying to find the answer of this question, you must know that a main electronic board controls all the operation of the refrigerator in new model refrigerators.
Sensors or temperature sensors regulates and check the temperature of the freezer and that of the refrigerator connected to this board, constantly. In fact, the main digital board powers the sensors, compressor, fans, and defrost system using data to control damper and flapper to create a balanced air.
High cold in the refrigerator is one of the signs which warns you about the malfunction of the board, but before checking the board, you must make sure that the damper or sensor works well.
The thermistor problem: the most common reason of refrigerator cold
Sometimes, the problem of the thermistor performance is the cause of refrigerator cold. Thermistor or sensor is a component which measures the temperature and send information to the control circuit. The control circuit also regulates the input energy of fans, compressors, as well as evaporators after receiving the temperature and then controls the refrigerator temperature.
Thus, if the thermistor has a problem, this process will be disrupted. Therefore, the fan of the compressor and that of the evaporator work more than usual, the refrigerator temperature drops, and food freezes!
Do not forget that the thermistor or temperature sensor has the specific resistance on the basis of temperature. So if the technical specifications of the specific resistance are not clear, it is not easy to troubleshoot.
What is the thermostat or temperature control board?
Thermostat is one of the most familiar components of refrigeration equipment that you have probably heard of. It is a component which controls the temperature of different parts of the refrigerator.
When the temperature of the refrigerator increases and the cooling decreases, thermostat identifies this change and sends the voltage to the compressor, evaporator fan, and condenser fan motor. So, it makes the interior of the refrigerator cool enough.
Therefore, the reason of extreme cold of your refrigerator may be a faulty thermostat.
It is noted that some refrigerators have temperature control board instead of the thermostat. The main work of this component, like thermostat, is to deliver energy to the compressors and motor fans.
If this board is damaged and sending voltage to these components is not stopped, eventually you will be left with frozen food in the refrigerator!
The reason of the frost in the non-frost refrigerator
However, today’s refrigerators do not require to defrost, sometimes you may see the frost in your non-frost refrigerator!
This evet may happen due to some reasons that in the following, we check them together. But before that, you must know how the frost creates.
The frost creates due to mixing cold air with hot/humid air in the refrigerator! So, if your refrigerator frosts, you should know where this hot/humid air gets into the refrigerator.
If you live in the humid climate zone and install your refrigerator close to the window that humid air gets into the refrigerator, you should change its location.
Placing a samovar near to the refrigerator also allows humid air to enter your refrigerator.
The refrigerator rubber may have a problem and air may infiltrate.
If none of the above cases is not true for your refrigerator, so it is better to look at the thermostat.
Solving the problem of extreme cold in the refrigerator
At the first of this post, we tried to mention all things which cause the interior space of the refrigerator to become too much cold. But now, we want to explain you some easy solutions. We also propose that if you cannot solve your problem, you should contact a professional refrigerator repairman/woman.
Troubleshooting is the most important part of home appliance repairs. We suggest that you first identify the main problem of the device before doing anything else. Once you find the problem of your device, you can repair it.
- If the problem of this device is related to the temperature control board, you should take an action and fix it. Note that repairing, adjusting, or replacing the control board requires high skill that it must be done by a professional repairman/woman.
- If the appliances in your refrigerator freeze constantly, it is better to check the thermistor with a voltmeter. If the resistance of the thermistor does not match with the temperature of the refrigerator, you will require to replace this component.
- To solve the extreme cold problem of the refrigerator in the thermostat part, you should turn the thermostat selector from the lowest value to the highest value and pay attention to the clicking sound. If such a sound is not heard, it must be repaired or replaced.
- The next thing that you must check is the damper control system. To solve the problem of the damper control system, you should correct the system or replace it to solve the freezing problem of appliances in the refrigerator.
The above things are the problems which most likely cause the items inside the refrigerator to freeze.
Preventing the refrigerator from freezing
- Keep the door closed.
- Organize food inside the refrigerator.
- Do not overfill or overempty the refrigerator.
- Do not place hot foods and items in the refrigerator.
- Dry food before placing in the refrigerator.
- Use suitable containers to store food in the refrigerator.
- The temperature inside and outside the refrigerator must be appropriate.
In this post, we checked the cause of extreme cold in the refrigerator, thoroughly. So, if you are looking for the cause of freezing inside the refrigerator, this information help you find the reason as soon as possible whenever your refrigerator does extra work and creates more cold.
Of course, in most of the cases, even if you find a problem, you cannot solve it without any expertise. So, if you do not have any skill in this field, it is better to leave this work to the experts of agencies; because you may damage the refrigerator or other parts more.
