The refrigerator won t defrost automatically, what should I do?

There are two types of refrigerators: direct cooling and air cooling. Direct-cooling refrigerators are prone to frost when the weather is humid and when the door is opened frequently. Generally, it should be defrosted every 7 to 10 days.

Here's how: unplug the electric latch, take out the food, open the door, blow it with a fan, and connect the basin to the refrigerator. When the ice begins to melt, use a wooden spatula to scrape the ice (never use a metal spatula).

After removing the ice and wiping it with a towel, you can put it in and use it normally. Of course, if conditions permit, it is better to change to a new air-cooled and frost-free refrigerator, once and for all, and no longer need to defrost once a week.

The most basic method is to adjust the temperature compensation to 0 first, then close the refrigerator (if there is no temperature compensation, turn it off directly), unplug the power, take out all the contents and drawers in the freezer layer, let the frost inside melt naturally, wipe dry with a rag, and then restore. Cut off the power of the refrigerator, clear the contents of the refrigerator, use a hair dryer or electric fan to slowly blow the ice, and add a towel to absorb water at the bottom of the refrigerator. After all the ice has been cleaned, it is best to wipe it with a clean towel moistened with venom and then moisten it with water.

It depends on whether your refrigerator has a defrost function If you have it, it is generally a defrost heating wire or heating tube that is broken Replace it But that is hidden in the back of the refrigerator It is recommended that you let the maintenance personnel come to repair If the refrigerator itself does not have a defrost function, it can only be manually defrosted Unplug the power plug and wait for a few hours You said that it is not okay to use a hair dryer to defrost because the internal copper pipe is cold when the refrigerator is cold It is easy to heat up and shrink the copper pipe.

Hello friend, I think you can turn off the refrigerator and then his, automatically turn it off and then the water can be drained. I hope mine can give you some help, and I wish you good luck and peace, and be happy and happy every day.

First, check whether the temperature is adjusted correctly, and then see if the drain hole in the refrigerator is blocked.

1. Why is the freezer defrosted?

Because the frost is too thick, it will lead to a decrease in heat transfer efficiency and a decrease in refrigeration efficiency, resulting in long compressor operation time and increased power consumption. Manual defrosting is very simple, twist the thermostat to the stopping position or unplug it directly, then take out the food, let the hot air in, and when the frost melts, dry it with a towel.

Second, the freezer defrost cleaning cycle.

Generally speaking, it is more appropriate to remove frost once a month and a half or two months.

3. Freezer defrosting method.

1. Use boiling water to melt the ice, put the boiling water in a container, then close the refrigerator, and slowly increase the heat to melt the ice.

2. Use a hot towel to apply it, and the hot towel is applied to the frost, which can quickly make the ice layer fall off.

3. Paste a layer of plastic film on the inner wall of the refrigerator, and only need to remove the film when de-icing.

Usually when we use the refrigerator, we pay more attention to the use of the refrigerator, pay attention to the food not to put too much, at the same time there must be a certain gap between the food and the food, and do not directly put the hot food in the refrigerator, which will affect the operation of the refrigerator.

Because the frost is too thick, the heat transfer efficiency decreases, and the refrigeration efficiency decreases, resulting in long compressor operation time and increasing power consumption, so the refrigerator needs to be defrosted. Having a hair dryer at home can greatly reduce the defrosting time.

It is normal for the refrigerator to have frost, and it is possible to frost if the refrigerator is too hot and has too much moisture, and the refrigerator door opens and closes frequently. In fact, refrigerators have frost, but frost-free refrigerators can automatically defrost through air conditioning circulation, and we don't need to defrost ourselves.

Today's refrigerators have compressors, which transport heat through electrical energy, which is active cooling. Frost plays a counter-action here, knowing that ice is a good thermal insulating material, and igloos are built on this principle. Therefore, the wall of the pipe with low temperature is covered with ice, and the temperature cannot be transmitted to other places after the ice is covered, and the temperature of the food will not be able to drop due to frost.

If the temperature doesn't come down, the refrigerator will work harder, and this will be a vicious circle.

When the wall of the refrigerator is frosted, the heat exchange between the air in the refrigerator and the cold air around the refrigeration pipe is hindered, and the refrigeration effect is reduced. The heat exchange of the refrigerator is conducted through the wall of the refrigerator, and the metal is a good conductor of heat.

The simple point is that the refrigerator will freeze after a long time, and if you don't clean the ice inside, it will affect the refrigeration effect.

Generally, this situation is caused by the poor sealing of the refrigerator or the fact that there are too many contents in the refrigerator.

The defrosting timer calculates that the compressor stops the power supply to the compressor and the circulating fan after working for 17-24 hours, and at the same time supplies power to the evaporator and the heating wire of the water tank through the defrosting thermostat and temperature insurance, and disconnects the power supply to the heating wire when the defrosting thermostat monitoring reaches the critical point (the temperature of the defrosting thermostat), so that the process of defrosting is over, and then the timer resumes the power supply to the compressor, and delays the power supply to the circulating fan for a few minutes, and the re-cooling starts.

Every frost-free refrigerator has a mechanical or electronic defrosting system, and when the compressor has been working for a period of time (around 8-12 hours) the surface of the fin evaporator will also frost. The middle part of the fin evaporator is equipped with an electric heating wire and a bimetallic temperature control and a temperature fuse, and the evaporator is heated by the electric heating wire to a certain temperature during defrosting, and the bimetal temperature control is disconnected after the defrosting is over, and the refrigeration is resumed. The water formed by defrosting flows from the tank to the water storage box at the bottom of the refrigerator through the diversion pipe, and automatically evaporates when heated.

There is a defrosting device in the refrigerator, this device is composed of three parts, the main one is an electric heating wire tied to the evaporator coil, there is a thermistor and a bimetal switch near the heating wire, the degree of induction heating is not overheated, and the last one is the defrost timer.

Heating pipes are installed on both sides of the refrigerator, and when frost falls, the heating pipes are energized. If the temperature of the box wall is too high, there will be no frost.

1. If the purchased refrigerator has an automatic defrost function, but there is no such effect, it may be that the merchant sent the wrong goods or the location of the temperature control of the nuclear silver Tansun cream is not suitable, and it may be good to adjust it.

2. Some models can be defrosted automatically.

3. The refrigerator adopts air-cooled refrigeration mode and has automatic defrosting equipment. In particular, high-end refrigerators are almost all frost-free; Generally, more than 5,000 yuan have this function. If you feel that it is expensive, you can find a way to defrost it yourself; Refrigerator refrigeration methods are generally divided into direct cooling and air cooling, the wind chain cold refrigerator can be automatically defrosted, the direct cooling refrigerator can not be automatically defrosted, manual defrost is required, the refrigerator with the first letter after the volume in the general refrigerator model name is w is an air-cooled refrigerator.

4. The defrosting timer is broken and damaged.

5. The defrosting heating tube is broken.

6. The defrosting temperature control is bad, and it is checked separately.

It is normal for the refrigerator to be in automatic cream. The defrosting timer calculates the power supply to the compressor and the circulating fan after 17-24 hours of operation, and at the same time supplies power to the evaporator and the heating wire of the water tank through the defrosting thermostat and temperature insurance, and disconnects the power supply to the heating wire when the defrosting thermostat monitoring reaches the critical point (the temperature of the defrosting thermostat), so far a defrosting process is over, and then the timer resumes the power supply to the compressor, and delays the power supply to the circulating fan for a few minutes, and the re-cooling starts. Open the state of emptiness.

Disadvantages of frost-free refrigerators1. Food is easy to dry and lack of water.

Because there will be cold air circulating inside, which will make the air humidity in the refrigerator low, some foods are easy to lack water if they are not isolated with plastic wrap or crisper boxes, and then be blown dry. Therefore, many air-cooled refrigerators are designed with smaller storage boxes, which are not only convenient for food information, but also to slow down the air-drying speed of food.

2. The noise is slightly louder.

Air-cooled refrigerators require fans to constantly blow cold air to all corners of the refrigerator, so relatively speaking, the noise will be a little louder than that of direct-cooling refrigerators.

The automatic defrost of the refrigerator is the defrost function of the new shoe refrigerator, which is the function of the mobile phone.

If the purchased refrigerator has an automatic defrost function description, but there is no such effect, it may be that the merchant sent the wrong goods or the location of the defrosting temperature control is not suitable, and it may be good to adjust it.

2. Some models can be defrosted automatically.

The refrigerator adopts an air-cooled refrigeration method and has an automatic defrosting equipment. In particular, high-end refrigerators are almost all frost-free; Generally, more than 5,000 yuan have this function. If Juewu is expensive, you can find a way to defrost it yourself; Refrigerator refrigeration methods are generally divided into direct cooling and air cooling, air-cooled refrigerators can be automatically defrosted, direct-cooling refrigerators can not be automatically defrosted, manual defrost is required, general refrigerator model name in the first letter after the volume is w refrigerators are air-cooled refrigerators.

3: The defrosting timer is broken and damaged;

4: Those who have a bad cavity of defrosting heating tube;

5: Defrost the temperature control is bad, check it separately.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. Inside the box there is a compressor, a cabinet or box for ice making for icing, and a storage box with a refrigeration unit.

The volume of a household refrigerator is usually 20 500 liters. In 1910, the world's first household refrigerator with compression refrigeration came out in the United States. In 1925, the Swedish Lido company developed the household absorption refrigerator.

In 1927, the General Electric Company of the United States developed a fully enclosed refrigerator. In 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. In 1931, a new type of refrigerant freon was successfully developed, and in the second half of the decade, it began to produce household thermoelectric refrigerators with dates, and China began to produce refrigerators in the 50s.

Summary. The frosted parts of the refrigerator are only found in the freezer, so defrosting is generally for the freezer compartment; 1. It is more appropriate to find a freezer to defrost when there are few things in the freezer; Put the contents of the freezer into the refrigerator first2, turn off the switch, and unplug the power; 3. Take out the drawer and place two cups of hot water in the freezer to accelerate the melting of the frost; At this time, also wash the drawer first4, about a few dozen minutes later, the refrigerator is almost melted, and wipe the frosty place repeatedly with a towel; Repeated wiping in this way can also quickly remove the frost. 5. After the frost is removed, use a dry towel to dry the moisture in the refrigerator.

so as not to frost again. 6. Connect the power supply, let the refrigerator cool, and after the temperature almost reaches the set temperature, move the things back to the freezer.

Can you tell us more about that?

That's it

In addition to the problem of use, there may be the following reasons for the refrigerator not to defrost: 1. The defrosting trouser is broken, 2. The defrosting heating tube is bad, and 3. The temperature control of the defrosting is bad, and they are checked separately. In addition, if it is a new refrigerator, it may be that the location of the defrost temperature control is not suitable, and it may be good to adjust it.

Don't worry too much about it, it's easy to solve.
