The freezer works without refrigeration, and the freezer is functioning normally but not refrigerate

1. The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not suctioning, so although the compressor is running, it is not refrigerated.

2. The refrigeration system leaks, the refrigerant runs out, and although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, so the temperature in the refrigerator does not drop.

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

Refrigerator does not refrigerate exclusion method.

1. Cut the casing, replace the buffer tube, or tighten the screws.

2. Find out the leakage part of the system first, and add refrigerant to a certain amount after passing the welding repair, pressure test and evacuation, usually according to the evaporator is full of frost or the refrigerator reaches the rated temperature.

3. The capillary tube or dryer is blocked, and the outlet is hot, so remove it to remove it! In addition, there are generally two types of household refrigerators: direct cooling and intercooling, which refers to the heat exchange between the evaporator (cooling pipe) and the freezing and refrigeration rooms to achieve the purpose of cooling; Intercooling means that the evaporator (cooling pipe) is separated from the freezing and refrigeration room, and the cold air is blown into the freezing and refrigeration room by a fan to achieve the purpose of cooling.

I also want to know the answer, I want to find someone to repair the refrigerator, in addition to being free, I am afraid of being pitted. If something is broken, just buy it yourself and replace it, I hope there will be a big guy to help us.

Normal operation without refrigeration is mostly due to refrigerant leakage.

The reasons and solutions for the normal operation of the freezer but not refrigeration, do not disassemble it without authorization.

If the freezer has been used for a long time, then there may be some problems with the refrigeration system, maybe the refrigerant is missing, if the freezer has just been bought and has not been used for too long, then it may be a problem with temperature regulation, or a problem with the power supply, which needs to be checked and eliminated one by one.

1. If the freezer is not refrigerated, first check whether there is a problem with the socket, power supply, etc. First look at whether the socket is powered on normally, whether the work indicator light is on normally, if these are not, then it may be power-off, replace the socket or plug-in board.

2. Problems with the refrigeration system. Generally, the freezer is not refrigerated, because the refrigeration system is faulty, such as whether the refrigerant in the refrigeration system is missing, whether there are loopholes in the entire pipeline of the refrigeration system, or whether the capillary part of the refrigeration system is blocked, or the capillary is crushed during transportation. These are all common reasons for the failure of freezers that do not refrigerate.

3. Check the expansion valve and outlet valve of the refrigerator to see if the valve is not properly adjusted, or there is too much refrigerant in the system, there is air in the refrigeration system, the valve plate assembly is poorly sealed, and the compressor liner piston is worn. These are all major faults, and maintenance is more troublesome. In addition, compressor failure is also common in this problem, such as the high-pressure output buffer pipe in the compressor is broken, or the screw fixing this tube is loose, resulting in the high-pressure pipe not exhausting, and the low-pressure pipe not suction, so although the compressor is running, it is not refrigerated.

1. The high-pressure car output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, resulting in the high-pressure pipe not exhausting, and the low-pressure pipe not suctioning, so the compressor is running but not refrigerating. 2. The leakage of the refrigeration system causes all the refrigerant to run away, so although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, so the temperature in the electric freezer will not drop. 3. The capillary is blocked, and the refrigerant cannot enter the evaporator to evaporate and absorb heat, so the temperature in the electric freezer does not drop.

Suggested solutions: 1. Find out the leakage part of the system first, weld repair, pressure test, and evacuate qualified, and add refrigerant to a certain amount, usually subject to the frost in the closed evaporator or the rated temperature in the freezer. 2. If the capillary tube or dryer is clogged and the outlet is hot, it needs to be removed and removed.

In addition, there are generally two types of household freezers: direct cooling and intercooling, which refers to the heat exchange between the cooling pipe and the freezing and refrigeration rooms to achieve the purpose of cooling; Intercooling means that the cooling pipe is separated from the freezing and refrigeration room, and a fan blows cold air into the freezing and refrigeration room to achieve the purpose of cooling. 3. Check whether the freezer power plug is plugged in; The electrical socket is not electrified; Whether the power circuit breaker is disconnected. Check that the refrigerator door light is on to make sure the freezer is plugged in.

Also check whether the thermostat is in the working gear, if the thermostat has a shutdown gear, the compressor will definitely not work if it is placed in the shutdown gear. If the above items are normal, it is recommended to contact professional maintenance personnel to solve the problem.
