What to do if the refrigerator ice is blocked, and how to deal with the refrigerator ice blockage?

After the refrigerator or freezer leaks in the system, it is easy to increase the moisture in the pipeline system after pressure and leak detection, and form an ice plug after adding refrigerant. Usually, some maintenance personnel use methods such as repeatedly adding and releasing refrigerant, replacing filters, blowing with nitrogen, vacuuming on both sides, and adding methanol to solve the fault of ice blockage, but these methods not only increase costs and waste resources, but the operation is also complex and troublesome. In fact, the following simple and practical methods can be used to solve the ice blockage, and the specific operation process is as follows:

1. After repairing the leakage of the refrigerator pipeline system, vacuum the system for about 1 hour;

2. Add a small amount of refrigerant to the system to restore the pressure gauge pointer to the left and right;

3. Run the refrigerator compressor and shut down for about 20 minutes. After waiting for the pressure of the system to be balanced, open the three-way valve to release the gas in the system (if there is an ice blockage during operation, wait for the ice blockage to naturally dissolve and the pressure is balanced before releasing the gas);

4. After the gas is discharged, weld any end of the filter drier with a welding torch (note that the welding is not cutting), and then place the end of the filter opening vertically upward, and trim the open end of the filter and the nozzle end of the butt. The purpose of this is to be able to smoothly butt weld the tubing when it is restored at a later date. Then use the outer flame of the welding torch to bake the filter evenly heated, after no gas comes out of the filter opening, use glass or iron plate to block it at 1 2cm away from the filter opening to see if there is any water vapor, if there is, continue to bake until there is none.

When there is no water vapor, immediately plug the filter and the tubing while it is hot and weld it well.

5. Re-vacuum the system and add refrigerant.

Note: Ensure that the environment is well ventilated during the above operation.

Causes of ice blockage.

1. Changing the compressor produces ice blockage, a refrigerator compressor is suddenly damaged, replacing the compressor must open the piping system, because the temperature of the evaporator is much lower than the ambient temperature, a large amount of air enters and combines with the cold air inside will generate water sustenance.

2. The pipe of the refrigerator is pierced by a knife, so that after the shutdown, a large amount of water will be sucked in at the next time.

3. When injecting a large amount of air into the leak detection, it will form water in combination with the cold air inside. The correct method is to use nitrogen to suppress the leak detection.

4. Replace the evaporator system, and the vacuum is not thorough.

Solution. This method is a bit more cumbersome, but it is very thorough and saves time.

Disconnect the high-pressure pipe before the filter drier, string a large freezer here with that kind of removable large filter dried, fill with silica gel, fill with a small amount of refrigerant, and then seal, start the machine and transport ** cycle. Stop the machine once every hour, rest for half an hour, turn on the machine, repeat this, about 6 times to open the machine, wait for the temperature of the freezer to be consistent with the ambient temperature, open the sealing tube and release the system gas, remove the large filter dried, replace the original filter drier with a new filter-dried, and the welding is completed. Vacuum with a vacuum pump for 1 hour, and fill the refrigerant with normal weighing.

Complete the commissioning. This method is very effective because the large filter drier for freezers can absorb a large amount of water and can be reused. This can also be used for air conditioners.

Just be careful not to compress the overtemperature run.

What should I do if my fridge is clogged? Just deal with it once like this.

The system is flushed with high-pressure nitrogen and re-vacuumed, while the filter drier must be replaced. Because since the ice jam has occurred, it means that the old filter drier is saturated and has failed. If this problem suddenly appears in the old machine, it means that there must be a leak at the low-voltage end of the system (evaporator side), pay attention to leakage and repair!

Refrigerator ice blockage, generally at the capillary outlet, ice blockage is caused by the refrigerant and refrigeration oil containing moisture, so only need to replace the refrigerant and refrigeration oil.

This is not necessarily an ice blockage, it has to be tested by pressure, and the master does not actually need to discharge the vacuum when repairing the refrigerator, and the freon saturation method is used, and I am not good to tell you here.

Novice maintenance refrigerator, to ensure cleanliness, there is to drain the vacuum, but also to replace the dryer, the ice plug will not burn the compressor, there are many maintenance without vacuum, add methanol, get too much, the compressor is easy to break.

The quick solution to the ice plugging of the refrigerator is the water removal method of discharging refrigerant, the drainage method of the dry filter screen, and the ice plugging method of too low temperature. Wax front can not be treated with formaldehyde.

1. Discharge refrigerant water removal method in the open discharge area.

When the ice blockage is more serious, the refrigerant discharge method can be adopted, which should be run with the machine, and the refrigerant will be discharged with the help of pressure, and then the water in the machine can be discharged to the outside of the machine by means of vacuuming and pipe wall heating.

2. Dry filter screen drainage method.

First, heat the compressor, connect the drying filter to the end of the capillary, drill a 1 mm hole between the capillary and the filter, and then heat the drying filter to let the water out of the hole. Fresh dry air is constantly fed into the process pipes.

3. Ice plugging method when the temperature is too low.

If there is ice blockage in the zero degree climate, don't rush to put the refrigerant first, turn off the machine and wait for 24 hours before turning it on, so that the ice blockage problem is solved. Because the refrigerator has been shut down for a long time, when it is turned on again, the dry filter can absorb the moisture from the ice jam.

Ways to avoid ice jams in the refrigerator

1. Check the seal regularly.

When using the refrigerator daily, after opening the refrigerator, close the refrigerator door with your hands and check whether the seal on the door is intact at the same time. If the seal is deformed or falling off, it will directly affect the tightness of the refrigerator door, which will easily cause the cold air to leak out, which will increase the power consumption of the air conditioner. If only the seal falls off, just put it back on, if the seal has been seriously deformed, it is necessary to replace the seal in time.

2. Defrost regularly.

After the refrigerator works for a period of time, it will produce some frost inside, although this is a normal phenomenon, but if there is no regular defrosting, the refrigeration effect of the air conditioner will not be ideal, which will increase the power consumption of the air conditioner, will speed up the aging of parts, and even cause damage to its compressor. Generally speaking, when the height of the frost is greater than 7 cm, it is necessary to defrost it.

Refrigerator ice blockage is mainly caused by the following reasons:

1.Setting the temperature too low: If you set the temperature of your refrigerator too low, it can cause condensate to freeze and accumulate in the cooling chamber.

2.Fluorine leakage or insufficient refrigerant: If the refrigerator leaks fluoride or does not have enough refrigerant, it can cause the cooling system to not work properly, resulting in ice jams.

3.Poor refrigerator sealing: If the refrigerator door is not well sealed, air will flow into the cooling chamber, causing the condensate to freeze and form an ice blockage.

Here's how to fix it:

1.Adjust the temperature setting: Adjust the refrigerator temperature to the appropriate range, and avoid raising the refrigeration temperature to avoid too low a refrigeration temperature. The temperature can be adjusted according to the recommendations on the refrigerator's instruction manual.

3.Confirm the tightness of the door: Check the tightness of the refrigerator door, and replace the worn, aging, and broken door seals in time. Also, when closing the refrigerator door, make sure that the door is completely closed and that there are no air leaks.

4.Regular cleaning: Regularly clean up dust and dirt in and around the refrigerator to ensure good air circulation and a good cooling system.

It should be noted that in order to avoid the occurrence of ice blockage in the refrigerator, we should carry out regular inspection and maintenance. If there is a serious problem with the refrigerator or it will not be repaired, please contact a professional for support and handling.

The refrigerant is discharged, and then the system pipes are cleaned and dried, and the water in it can be re-vacuumed and fluoridated.

<> solution to deal with the blockage of the refrigerator: 1. Open the refrigerator door and find the location of the small hole, if you find a lot of water, it means that the drainage hole is blocked. 2. The location of the drainage hole of each refrigerator is different, use a small toothpick or a small bamboo stick to get through, if the blockage is not very bad, it can generally be opened.

3. If it can't be opened, find a syringe, cut off a section of plastic infusion tube, put the plastic infusion tube on the syringe, insert the hose into the small hole, and suck out the water inside.

4. After sucking the water out, fill up a syringe with water, drive it into the small hole, and try to see if the drainage hole is open.

5. If the water does not overflow, it means that the drainage hole is open, then clean the refrigerator, and wipe the refrigerator after washing.

When there is ice blockage inside the refrigerator, it may cause the temperature of the refrigerator and freezer to rise, and may even affect the operation of the entire refrigerator. Here are a few effective ways to deal with the problem of ice blockage in the refrigerator.

1.Arrange the food properly.

When too much food accumulates inside the refrigerator, it can hinder the air circulation and cause ice jams. Therefore, keeping food properly can alleviate the problem of ice blockage. It is advisable to tidy up the contents of the refrigerator frequently and allow it to be fully ventilated.

2.Clean the fridge water pan.

The water pan of a refrigerator is often used to collect moisture from the inside of the refrigerator in order to prevent freezing. However, if too much water accumulates or becomes contaminated in the pan, it can lead to ice blockage. Therefore, regular cleaning of the refrigerator water tray is the key to solving the problem of ice blockage.

3.Start the defrost function.

Modern refrigerators are usually equipped with a defrost function. When there is an ice jam problem in the refrigerator, you can activate the defrost function to solve the problem. Some of these refrigerator defrost functions can be activated by pressing a button or by manually re-fixing the cooler for a period of time.

4.Change the temperature setting.

The temperature setting may affect the temperature inside the refrigerator, which can lead to ice jams. If the temperature set by the refrigerator is set too low, it will cause the bottom to freeze, and it is recommended to increase the temperature to an appropriate level.

In short, when there is an ice blockage problem in the refrigerator, it can be solved by the above methods. Maintain good fridge performance by keeping food handled properly, cleaning the water pan regularly, activating the defrost function, and adjusting the temperature.

If the drain hole of the refrigerator is blocked accordingly, it is necessary to clean the drain hole in time, if the ventilation hole of the refrigerator is obviously blocked, it will also affect the comprehensive refrigeration efficiency inside the refrigerator, and the ventilation hole should be checked regularly when the refrigerator power is turned off.

1. In the process of working of the refrigerator, there will inevitably be a certain amount of water accumulation inside, if it is not discharged in time, it will cause very obvious frost inside the refrigerator, and there will be certain errors in the refrigeration efficiency and temperature control of the refrigerator, which is due to the fact that there is a certain blockage in the drain port of the refrigerator, and the user needs to re-detect and clean the drainage hole to ensure the normal drainage working environment.

2. The inspection of the ventilation hole of the refrigerator is also a very important link, because the refrigerator is in the actual working process, it is necessary to remove the hot air inside the refrigerator in time, which can ensure a stable refrigeration working temperature. In the case of blockage, it will reduce the refrigeration effect of the refrigerator, and at the same time, it will also increase the power consumption and working time of the refrigerator, resulting in a certain shortening of the service life of the refrigerator. It is believed that for professional users, regular refrigerator maintenance will also be carried out, so as to ensure a stable working environment.

1. Vacuuming. When eliminating the ice plugging fault, the refrigerant is discharged first. The refrigeration system is vacuumed and filled with dry nitrogen.

Start the compressor to run until the dry nitrogen absorbs the moisture before vacuuming, and so on several times. The refrigeration system should also be replaced with a new filter drier when it is restored. During the filling process of high-quality refrigerant, the filter should also be dried to absorb as much water as possible from the refrigerant.

2. Drying treatment. Before the refrigeration parts are loaded into the system, they must be dried in a constant temperature drying oven. For complex parts, such as a fully enclosed compressor, it is necessary to bake for 816 hours in a constant temperature environment of about 105 (slightly higher than the boiling point of water at local atmospheric pressure) to allow the water to vaporize and discharge.

However, the temperature should not be too high, as temperatures above 120 will damage the motor insulating medium. Generally, parts with simple structure can be baked for about 4 hours. If possible, vacuuming while baking can reduce the pressure or temperature, as this will lower the boiling point of the water and facilitate the discharge of water.
