There are many reasons why the upper floor of a vertical freezer is not refrigerated, specifically there are 6 reasons.

1) The capillary tube of the freezer is blocked, resulting in the refrigerant being unable to enter the evaporator, so it cannot absorb the heat emitted by the refrigerator, and the temperature in the freezer cannot drop, resulting in the phenomenon of non-refrigeration.

2) It may be because the screws that hold the buffer pipe with the high-pressure output inside the compressor are no longer strong, or because the buffer pipe is broken, so the low-pressure pipe cannot suction and the high-pressure pipe cannot exhaust, although the compressor is running, the freezer is not refrigerated.

3) There is a problem with the refrigeration system, such as leakage, and the freezer that lacks refrigerant to absorb heat naturally does not refrigerate, which is a relatively common phenomenon.

4) The outlet valve and expansion valve of the freezer are not properly adjusted, and the components of the valve plate are not sealed well, resulting in cold air leakage, or the compressor piston is worn, which also needs attention.

5) The leakage of the refrigeration system may be due to the fact that the freezer is not welded well or there is a problem with the use method, resulting in slow refrigeration and no refrigeration.

6) It may be that the refrigerator refrigeration gear is too low, which will affect the temperature of the freezer, which also requires you to do an independent inspection.

1) If the capillary is blocked, the capillary must be removed for cleaning, so that the effect of refrigeration can be achieved.

2) If there is a problem with the buffer tube, you can only open the casing, fix the screws or replace the buffer tube, and the problem will be solved.

3) If there is a problem with the refrigeration system, first find out the location of the leakage of the refrigeration system, weld the position, test the pressure, evacuate, when all the standards are qualified, and then add a certain amount of refrigerant until the freezer reaches a certain temperature.

4) If there is a problem with the expansion valve and the outlet valve, first power off the freezer, then rotate the inlet valve to the end in the counterclockwise direction, remove the screws, install the "wire" and then install the pressure gauge and connecting pipe, close the gauge valve, rotate the inlet valve in the clockwise direction to make it tee, and observe whether the internal pressure of the freezer is normal;

5) If it is a gear problem, you need to adjust the gear according to different seasons and temperatures.

You can see everywhere, when you encounter the freezer is not refrigerated, the first reaction is to call the maintenance personnel, but I think that we should first observe, understand, and find out the reason why the freezer is not refrigerated. Below, let's analyze some of the phenomena and causes of problems in vertical freezers and how to solve them.

Introduction to upright freezers.

Vertical freezer is an electrical equipment used to refrigerate beverages, yogurt, cakes and other foods, and the refrigeration temperature is generally 0 -10, which is generally in supermarkets, convenience stores, and hotels.

Bar. Cake shops, food stalls and other occasions that require refrigerated food.

Reasons why upright freezers are not cooling.

1.The freezer's capillary tube is blocked, preventing refrigerant from entering the evaporator.

medium, so it can not absorb the refrigerator.

The heat emitted cannot be lowered in the freezer;

2.Probably due to the stationary compressor.

The screws of the buffer tube with the high-pressure output are no longer strong, or because the buffer tube is broken, so the low-pressure pipe cannot be suction and the high-pressure pipe cannot be exhausted, and although the compressor is running, the freezer is not refrigerated;

3.If there is a problem with the refrigeration system, such as leakage, the freezer that lacks refrigerant to absorb heat will naturally not be refrigerated;

4.Refrigerator. The outlet valve and expansion valve are not properly adjusted, and the components of the valve plate are not sealed well, resulting in cold air leakage, or the compressor piston is also very likely to be worn;

5.A leak in the refrigeration system may be due to the freezer not being welded.

Good or there is a problem with the use method, resulting in slow refrigeration;

6.It may be that the refrigerator refrigeration gear is too low, which has an impact on the temperature of the freezer.

What to do if the upright freezer is not refrigerated.

In view of the above problems, there are several ways to solve the problem of vertical freezer not being refrigerated

1.If the capillary is clogged, the capillary must be removed for cleaning;

2.If there is a problem with the buffer tube, you can only open the casing, fix the screws or replace the buffer tube;

3.If there is a problem with the refrigeration system, first find out the location of the leakage of the refrigeration system, weld the position, test the pressure, evacuate, when all the standards are qualified, and then add a certain amount of refrigerant until the freezer reaches a certain temperature.

4.If there is a problem with the expansion valve and the outlet valve, first power off the freezer, then rotate the inlet valve to the end in the counterclockwise direction, remove the screws, install the "wire" and then install the pressure gauge and connecting pipe, close the gauge valve, rotate the inlet valve in the clockwise direction to make it tee, and observe whether the internal pressure of the freezer is normal;

Adjust the gears according to different seasons and temperatures.

One. Cause analysis.

Check if the power connection is normal. Open the door and observe whether the light in the box is lit, or test it with an electric pen.

or the screws fixing this tube are loose, and the high-pressure output buffer pipe in the compressor is broken. As a result, the high-pressure pipe does not exhaust, and the low-pressure pipe does not suction, so although the compressor is running, it is not refrigerated.

The refrigerant ran out of compressor although it was running, 2Leaks in the refrigeration system. However, there is no refrigerant evaporation and heat absorption in the system, so the temperature in the freezer does not drop.

The refrigerant cannot enter the evaporator to evaporate and absorb heat, 3Capillary blockage. The temperature in the refrigerator does not drop.

Two. Exclusion Method.

Replace the buffer tube, 1Cut open the casing. Or tighten the screws. After welding repair, pressure test, and evacuation are qualified, 2Detect the leakage of the system first. Add refrigerant to a certain amount, usually according to the evaporator is full of frost or the rated temperature in the freezer is reached.

1. The lack of refrigerant causes the freezer to not refrigerate. 2. Frost in the evaporator causes the freezer hole to be regrouped and not refrigerated. 3. Failure of compressor or starter or thermal protector.

4. There is a problem with the thermostat. 5. There may also be a problem with the freezer compressor. Suggested workaround:

1. First of all, check whether the high-pressure section of the freezer refrigeration system is leaking. If it is an internal leak, the orange is formed due to the condensation and dew prevention pipe due to sand holes, fractures, cracks, etc., and the pipeline will be corroded until it leaks or leaks. The strength of the pipe wall at the leakage is weak, and it is manifested as leakage under high temperature and high pressure.

The refrigeration system leaks, the refrigerant slowly runs out, although the compressor is running, look at the system There is no refrigerant evaporation and heat absorption, so the temperature in the electric freezer does not drop. 2. If the compressor can be started, we first remove the return pipe, and slowly block the outlet with our fingers, check how much the downward pressure is, if it is low, then there may be a problem with the compressor that causes the compressor to not start, and check whether the power supply of the freezer is plugged in. 3. You can check whether there is a lack of freon.

Generally, most of the double-door electric freezer capillary outlet is advanced to the beginning of the freezer and then circulated, that is to say, the refrigeration at the beginning of the freezer and then the completion of the refrigerator, if the refrigerant is lacking, you need to add refrigerant.

The reasons why the upper level of the refrigerator does not refrigerate are as follows:

1.The exhaust vent is blocked:

The refrigerator thermostat is installed in the refrigerator, and the temperature of the refrigerator does not reach the temperature required by the thermostat, so it does not stop. If the compressor does not work around the clock, the freezer compartment may cause the refrigerant to reach the maximum refrigeration temperature.

Most of this phenomenon occurs in air-cooled refrigerators. The reason is that the evaporator flower froster in the cold room is broken, which produces an ice blockage. It cannot be ruled out that the air cooling fan is broken, and there are too many items in the refrigerator to block the air outlet, causing poor cooling effect.

2.Too many items in the fridge:

The temperature of the refrigerator is automatically adjusted with the temperature adjustment of the freezer, and the temperature of the freezer can be lowered. Generally, the temperature of the refrigerator room is 4-10 degrees Celsius.

Note that the higher the number of the temperature controller, the lower the temperature, the higher the number in summer and the smaller number in winter. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the refrigeration effect is not ideal.

3.Compressor malfunction:

The reason why the refrigerator is not cooling may also be that there is a problem with the refrigerator compressor. The compressor can start, remove the return pipe and block the outlet with your fingers, check how much the downward pressure is, if it is too low, then there is a problem with the compressor, if the compressor can not start, then check whether the refrigerator power is plugged in. This answer applies to any Haier refrigerator.

The upper floor of the refrigerator is generally set up for the refrigeration compartment. Not for refrigeration.

The most likely thing is that there is some degree of refrigerant leakage in the piping of the refrigerator refrigeration system.

When the refrigerant leaks and the amount of refrigerant is insufficient, the low-temperature and low-pressure liquid refrigerant has evaporated in the freezer pipeline below, and the refrigeration and cooling effect can be very poor or even no when it reaches the refrigerator room pipeline.

It is recommended to carefully detect the leak of the refrigerator refrigeration system, find the refrigerant leakage point, braze and repair the leakage, vacuum pump vacuuming, and refill the standard amount of new refrigerant after the negative pressure is qualified.

Hello dear 1, ice blockage. It is very likely that the freezer is not frozen above the freezer and the bottom is not frozen, resulting in the refrigerant cannot be circulated, because the compressor is running at high temperature, and it will lead to overheating and automatic shutdown when there is dust. 2. Lack of fluoride in the freezer.

If the freezer itself is refrigerated but fails, it is likely to be caused by refrigerant leakage, which will cause a situation where it cannot be refrigerated, so it is recommended to add refrigerant to it. 3. Frost in the evaporator. When the evaporator frost cannot be melted away, the air duct mouth is blocked, and the cooling capacity cannot go out, resulting in the refrigerator not being refrigerated.

This situation requires the replacement of the defrost timer or heating element. 4. There is a leak in the freezer pipe or evaporator. In this case, it is necessary to find the leak point for repair.

5. Freezer compressor problem. If the compressor return pipe pressure is too low, the compressor will not start, resulting in the refrigerator not being refrigerated. Check that the freezer power plug is plugged in properly, or that the power supply is insufficient, etc.

6. The exhaust valve of the freezer compressor is damaged. This situation will lead to a decrease in exhaust capacity, and the freezer will not be fully refrigerated and will need to be replaced. 7. The temperature controller is set too low.

Generally speaking, it is more appropriate to have a number between 3 and 4, and you can set it again.

Hello friend, when the refrigerator is working normally, it is fresh and refrigerated, and it is not refrigerated, which can only mean that Frion is not enough liquid brother. In this case, first fill in some Freon, and try to see how effective it is within ten hours after filling. If it still doesn't work, you need to look at the compressor, which may be the case that the compressor is not working properly.

This requires a professional to detect the incident to be determined.
