A thermic refrigerator, also known as a thermoelectric refrigerator, is a type of refrigerator that uses the Peltier effect to create a cooling effect. Unlike traditional refrigerators that rely on compressors and coolants, thermic refrigerators work by passing an electric current through two different types of semiconductors, which causes one side to become hot while the other side becomes cold.
The cooling effect in a thermic refrigerator is the result of a phenomenon called the Peltier effect. When an electric current passes through the semiconductors, heat is absorbed from one side and released from the other. The cold side of the thermic refrigerator is used to cool the interior of the refrigerator, while the hot side dissipates the heat outside.
However, like any other appliance, thermic refrigerators may encounter issues and become dysfunctional. Common causes of a broken thermic refrigerator could include power supply problems, excessive heat build-up, faulty fans or heat sinks, damaged wiring, or even a defective thermoelectric module. If your thermic refrigerator is not cooling as it should, there are a few steps you can take to fix it.
Firstly, check the power supply and ensure it is functioning properly. Make sure the refrigerator is properly plugged in and that the electrical outlet is working. If the power supply is fine, examine the fans and heat sinks to see if there is any dust or debris blocking the airflow. Cleaning these components can often resolve cooling issues.
If neither of these steps helps, it may be necessary to inspect the thermoelectric module. Look for any visible damage, such as broken or loose wires, and replace or repair them if necessary. Additionally, ensure that the temperature control settings are properly adjusted.
In summary, a thermic refrigerator is a cooling device that operates through the Peltier effect, using an electric current to create a temperature difference. If your thermic refrigerator is not functioning correctly, it is essential to troubleshoot and identify possible causes such as power supply issues, excessive heat build-up, or damaged components. By following appropriate steps to fix these problems, you can potentially restore your thermic refrigerator to proper working condition.
When the thermic of the refrigerator is broken, your refrigerator will appear to have symptoms such as weak cooling or not working. Join Dien May Xanh to find out what thermic refrigerator is, the cause and how to fix it!
What is thermic refrigerator?
Thermic refrigerator, also known as the sensor bulb, is located at the indoor unit location. It is connected to the thermal relay at the indoor unit by a long capillary. Inside the sensor bulb contains a liquid, when this liquid encounters cold temperatures, it will contract and expand when the temperature is heated.
In addition, the role of the refrigerator thermic is to monitor and control the operating temperature of the refrigerator at the most optimal level. Therefore, if thermic has a problem, it will cause the refrigerator to malfunction, or moreover, the refrigerator will stop working.
However, if not used in the refrigerator, usually thermic (thermal relay) will be a switch used to ensure the safety of all electrical equipment such as: electric motor, microwave oven, air conditioner block or refrigerator block,…
Signs to identify the refrigerator thermic is broken
The basic sign to recognize a broken thermic is that the refrigerator block is stopped unexpectedly, not in accordance with the normal operating principle of the refrigerator.
Besides, when the thermic is damaged, there will also be other signs such as: the refrigerator is less or not cold, the food stored in the refrigerator is rancid and damaged, …
Cause the thermic refrigerator is broken
Although today’s refrigerators vary in make and brand, they all have the same reason for the failure of thermic refrigerator.
Specifically, the cause of the failure of the refrigerator thermic is due to the failure of the bimetallic bar or the poor contact of the bimetallic bar to make the rod large and open.
How to fix a broken refrigerator thermic
When the thermic of the refrigerator is damaged, it is imperative that you replace it completely. Because this is a difficult case to fix, it cannot be repaired or replaced at home. The best way, you need to contact a reputable warranty center to promptly replace the thermic with a new one for your refrigerator.
Check the functions of the refrigerator when thermic has been repaired
After the thermic has been replaced, you need to check the functions of the refrigerator, to make sure your refrigerator is working properly, specifically as follows:
- If the refrigerator is working properly, when opening the refrigerator door, you will hear the sound of gas splashing in the indoor unit.
- The compression piping element will begin to heat up and the heating temperature must be gradually reduced thereafter, until the refrigerator filter is left with only warm air.
- The refrigerator works normally, you can hear a slight noise of the relay box right after plugging it in for 0.5 – 1s.
- The temperature relay is adjusted to the position corresponding to the smallest number, after a while the refrigerator must stop working. Besides, when the temperature rises, the refrigerator will operate as smoothly as before.
