How to repair the freezer if it fails?

If the freezer fails, it can be repaired by following these steps:

1.Check that the power supply and plug are connected properly to make sure the power supply** is normal.

2.Check that the temperature controller of the freezer is working properly, if not, it needs to be replaced.

3.Check that the compressor of the freezer is working properly, if not, it needs to be replaced or repaired.

4.Check the condenser and evaporator for accumulated dust and dirt, and if so, need to be cleaned.

5.Check that the refrigerant in the freezer is sufficient, if it is insufficient, you need to add refrigerant.

6.If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for repair.

When servicing your freezer, be sure to pay attention to safety to avoid electric shock and other hazards. If you're not sure how to make a repair, consult a professional.

Long-term operation of the refrigerator will cause the equipment to be clogged with limescale, which will reduce efficiency, increase energy consumption and shorten the service life. If limescale is not removed in a timely manner, there is a danger that the equipment will be repaired, shut down or scrapped for replacement. For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc., have many problems when cleaning the freezer, which can not completely remove deposits such as scale, and cause corrosion to the equipment, and the residual acid produces secondary corrosion or corrosion under the scale of the material, which eventually leads to the replacement of equipment, and the high-efficiency environmentally friendly cleaning agent can avoid the above situation, which has the characteristics of environmental protection, safety and no corrosion, not only has a good cleaning effect and no corrosion to the equipment, which can ensure the long-term use of the freezer.

This is usually caused by frequent opening and closing of the refrigerator, or it is possible that the temperature of the refrigerator is set too high, or it is also due to the failure of the refrigerator's compressor. It is recommended to minimize the number of times you open the refrigerator or change the compressor to a new one.

1. It may be because of the failure of the compressor, if it is a new machine, you can rule out the possibility of this aspect, but if it has been used for five or six years, and the buzzing sound becomes louder and louder during the operation of the refrigerator, it is important to consider the problem of the compressor, and it can be restored by directly replacing a compressor.

2. Frequent opening and closing of the refrigerator door leads to the diffusion of cold air. If you open and close the refrigerator door frequently, a large amount of hot air will enter the refrigerator, and the neutralization of hot air and cold air will increase the temperature, and it seems that the refrigeration effect will become worse, but in fact, the air conditioner is in working refrigeration mode, just wait for a while. Don't always turn the refrigerator on and off, as it is not conducive to the life of the air conditioner.

3. The temperature of the refrigerator room is set higher, and the refrigerator refrigerator has actually reached the set temperature value or gear, and has been in a constant temperature state or suspended refrigeration, so what needs to be done is to appropriately adjust the set temperature of the refrigerator room, which can be set in 2 or 3 gears, and the lack of Li Collapse is appropriately adjusted according to the seasonal changes.

The main signs of a proper functioning of the refrigeration lubrication system are:

1) The oil pressure gauge specifies that it is stable, and the indicated pressure should be higher than the suction pressure for the piston or freezer, and higher than the condensing pressure for the screw freezer.

2) The oil temperature in the crankcase should be kept between 10-65, and the most suitable working temperature is 35-55.

3) The oil level in the crankcase should be sufficient and should be stable for a long time.

4) The filter element of the oil filter should not be blocked, and the fine oil filter with differential pressure should have a signal indication of blockage. The most common faults in the lubrication system are: no pressure of the oil pump, failure of pressure regulation, and violent swing of the pressure gauge pointer.

Refrigeration failure Frozen to refrigerated??

This is a typical refrigerator leaking refrigerant phenomenon, a brief introduction to the principle you will understand because the refrigerator refrigerant, compressed by the compressor, into the condenser, and then through the filter dried, through the capillary throttling, into the refrigerator evaporator, the refrigerator has two evaporators, a refrigerated evaporator, a refrigerated evaporator.

Here's the main problem: the refrigerant after capillary throttling is the one that goes into the refrigerated evaporator first, and then into the refrigerated evaporator, (that is, the refrigeration of the refrigerator that you said has failed, and the freezer has become refrigerated,).

At this time, there is a leakage phenomenon in a certain part of the refrigerator system, resulting in insufficient refrigerant circulation supply, unable to supply the refrigerated evaporator, because it is a micro leakage, the leakage is quite slow, first the storage is slowly not refrigerated, after a period of time, the freezing is not refrigerated.
