How can I hear the sound of a refrigerator loophole

Your question is very unclear and you don't know exactly what you want to know. If you want to know the judgment that the cabinet foam is not true, as long as you tap the cabinet (a bit like shooting a watermelon), the sound is dull and foamy, and the sound is empty.

If you can, of course, buy a leak detector, which detects the approximate location of the smell of refrigerant. If not, use the foam inspection method, on the heat dissipation copper pipe of the refrigerator, or on the elbow of the outlet pipe. You use an empty plastic kettle to pour some dish soap or hand sanitizer and add water, not too much.

When you shake it, there are bubbles.

Because the refrigerator liner is made of aluminum blow molding, and the difficulty of aluminum welding is high, it is not easy for ordinary people to master, and the simple and easy way is to replace the evaporator (using copper pipe winding), which is not very high. The evaporator must be removed before it can be repaired, because the evaporator cannot be serviced in such a small space in the refrigerator. Secondly, the manufacture of the evaporator is formed in one time with a machine in the factory, and once it is destroyed, it is difficult to restore it by hand welding.

Third, the maintenance personnel door-to-door maintenance methods are quick repair, and finally settled by piece, if it takes a day to repair the evaporator of a refrigerator, even if it is repaired, it can only earn 20 yuan of wages. Therefore, how fast and easy to save is to change the pipeline as a whole!

Personal advice: When putting sharp, bulky metal, ceramic, glass and other sharp and hard objects in the freezer, remember, ah, it's the freezer! The action must be gentle, because the evaporator is in the freezer, and these things accidentally break the evaporator.

Adding a plugging agent to the refrigerant in the refrigerator can effectively prevent fluorine leakage in the refrigerator.

Look at the leakage, the copper pipe or the valve.

In the process of using our refrigerator, there will definitely be a failure due to some such reasons, which will affect our use very much, so if the refrigerator fails, how to repair it? Today, I will introduce some maintenance methods of the refrigerator to help you use the refrigerator better.

Refrigerator repairs – door opening checks or sensor failures.

Consult the user whether the door is opened frequently, whether the door can not be closed tightly due to too much food, consult the user to use it correctly, and check whether the door seal is flashed, and whether the door seal pressing area (pressing width should exceed 6mm) is sufficient. If the refrigeration effect of a certain temperature zone is poor, you can refer to the computer refrigerator sensor detection method to check whether the sensor parameters of the temperature control zone are normal.

Refrigerator repairs – faulty thermostat or main control board.

Adjust the temperature control gear to the appropriate gear, if the refrigerator is on for a short time, detect whether the temperature of the back evaporator reaches the shutdown temperature, and if the shutdown temperature is not reached, it should be a thermostat problem, and reaching the shutdown temperature may be a fault such as compressor overheating protection.

Refrigerator repairs. Refrigerator repair – poor compressor exhaust.

Open the refrigerator system, check whether the compressor exhaust is normal, the simple way is to use your finger to see if you can block the compressor exhaust port, if it is very volumetrically blocked, you can judge that the compressor exhaust is poor, if it is difficult to block, you need to use the second method to further judge. The first method is to connect the pressure gauge at the outlet of the condenser, check whether the exhaust pressure can be higher than and the gauge needle slowly retreats after power-off, if it cannot be reached, or even can not be reached, it can be judged that the compressor exhaust is insufficient, if the gauge needle quickly retracts, it means that the compressor strings gas.

Refrigerator repair – refrigerant leakage.

If the compressor is normal, it can be judged that it is a refrigerant leak, check the leakage point, and focus on checking the solenoid valve (which can be placed in warm water to detect the leak more accurately) and the frozen locke ring to prevent it from being judged to be internal leakage.

The refrigerator is out of power and washed again. Wash it regularly once a month.

The hazards are as follows:

1. If the refrigerator leaks fluoride quickly, and the room is not ventilated enough, the refrigerator freon leakage has a rapid suffocation effect. When the concentration of freon in the refrigerator is high, it can cause disorientation, nausea, vomiting, anesthesia, heart rate disorders, and even death after inhalation.

2. Fluorine leakage in the refrigerator, freon is the most harmful to the ozone layer, it will destroy the ozone layer, after the ozone layer is destroyed, the ultraviolet rays will increase, bringing a series of problems and increasing the incidence of some diseases.

Note: 1. The cause of fluorine leakage in the refrigerator is generally the failure of the refrigerator's compressor, evaporator or condenser.

2. The reason for fluorine leakage in the refrigerator may also be that the refrigerator has been used for a long time, which makes the machinery and equipment inside the refrigerator age, the closure of the machine decreases, and the freon in the refrigerator leaks out of the aging machine.

。I don't know if you have noticed such and such sounds in the refrigerator during use. Many people have asked me on this issue, so I will give you a brief introduction now, the sound of the refrigerator is emitted there, whether it is a refrigerator problem.

Our most common sounds are the sounds of running water that "hiss" and "gurgle, gurgle", and these sounds are normal. They are generated inside the refrigerator refrigeration system, and are the sound of the refrigerant flowing in the refrigeration system, which will never affect the refrigeration effect of the refrigerator. But then again, if there's no sound that's bad, I can only wonder if your fridge refrigeration system is clogged.

The upper part of the refrigerator may sometimes hear a "ticking" sound or a blowing sound, so it's normal not to be afraid of it. It is the sound of an automatic frost timer, and the sound of blowing is the sound of a fan turning on the upper part of a cooled refrigerator.

Some refrigerators make a "crackling" sound when they start or stop, this sound is normal, this sound mostly occurs on the evaporator and condenser, and will not have any effect on the refrigerator.

You should be familiar with the sound of "clicking", which is the sound of a hammer relay, thermal protector or defrost timer when the refrigerator starts and stops, which is a normal phenomenon.

If you find that the refrigerator box is hot, don't worry. It is the heat generated when the refrigerator compressor is running, and this heat is mostly dissipated through the compressor housing, so the refrigerator box is sometimes hot.

When you open the refrigerator, you are sure that the door seal of the refrigerator is a little hot.

The sound of water flow is the sound of refrigerant flowing, and the landlord may be lacking in refrigerant, causing the refrigerator to not refrigerate.

It is safe to say that it is a leak failure, and it is very likely that it is an internal leak. Thorough repairs must deal with the loopholes in order to be able to rejuvenate, and blind Gaver will make people's heart rhythm crisp and cried.

Refrigerant is lacking and needs to be replenished.

1. The noise of the refrigerator is mainly the working sound of the compressor;

2. The sound of thermal expansion and contraction of the evaporator or condenser;

3. Resonance sound between pipes;

4. The sound of the refrigerant in the pipeline;

5. The sound produced by the uneven placement of the product.

6. Different methods are used to eliminate different phenomena, such as installing shock absorbers, damping blocks, fixed parts, defrosting, etc.

It is recommended that you ask a customer service staff to come to check.

It should be the alarm sound that the refrigerator door is not closed. The landlord checked the door and took a look.

It must be caused by the compressor running.

Analyze the specific situation on a case-by-case basis!! Open the back cover of the refrigerator to see what the sound is ringing, so that others may help you solve it, and it is unreliable to imagine it out of thin air.
