What s the deal with the fact that the refrigerator has no noise?

1. During the use of the refrigerator compressor.

The work is subject to the thermostat.

If there is a problem with the thermostat, the contacts cannot be closed, the compressor will not work, and there will be no refrigeration and no sound. 2. When the temperature of the compressor shell is too high or the current on the compressor is too large, the contact of the overload maintainer jumps open and cuts off the circuit, so that no current on the compressor passes through the refrigerator, and the compressor does not work, and the operation is stopped, so as to maintain the compressor so that the compressor will not work and will not refrigerate. Suggested workaround:

1. Check whether there is a problem with the thermostat, if the thermostat has been damaged or the contact is not good, it needs to be repaired in time after the detection of professionals, and after the repair, it is adjusted to a suitable gear, and then the refrigerator should be restored to normal use. 2. There are overload maintainers inside the refrigerator, if it is overloaded for a long time, it will cause the overload protector of the refrigerator to stop working after a long time of use, in this case, it is recommended to unplug the power supply, contact professional maintenance personnel, overhaul the specific problem, and repair it in time after finding out the problem, so as to solve the problem of not refrigerating. 3. If the thermostat is not damaged but the adjusted gear is a little inappropriate, this situation only needs to be adjusted appropriately according to the ambient temperature.

Two situations: one is that the compressor works very quietly, so you can't hear the sound of the compressor running.

The second is that the compressor works intermittently, when the temperature in the refrigerator drops to the set temperature, the compressor will automatically shut down, and you can't hear the sound at this time. Especially in winter, due to the low ambient temperature, the compressor downtime is relatively long.

1. Refrigerant.

The sound of the normal flow. 2. The power supply is not properly connected. 3. There is a problem with the voltage and current, which conflicts with the voltage required by the refrigerator.

4. The ambient temperature is lower than the normal starting temperature of the temperature controller. Suggested solutions: 1. The refrigerant in the refrigerator is mainly vaporized by absorbing the heat of air or water, and then in the condenser.

It also transfers heat to air or water to produce condensation. To put it simply, refrigerants are sometimes solid and sometimes liquid. When it's liquid, there's naturally the sound of running water.

This is a normal phenomenon, if the sound is really loud, it may be that the sound insulation is not good. 2. There may be the following reasons why the refrigerator is not refrigerated: first check whether the lights in the box are on to determine whether the power supply of the refrigerator has been turned on.

If the light is on, the power supply is correct, you can proceed to the next check, if the light is not on, you need to use an electric pen or multimeter.

to check the electrical outlet.

Whether there is electricity or not, whether the power plug of the refrigerator is well plugged in. And check whether there are problems with the lines one by one, and repair them. 4. If the ambient temperature is lower than the normal starting temperature of the temperature controller, you should check whether the low temperature switch of the refrigerator is turned on.

Only when the low temperature switch is turned on can the temperature controller be turned on.

1. Check whether the lights in the refrigerator can be lit first, confirm that the power supply is good, and rule out the causes of power supply failures such as the power fuse is blown out, the power plug is in poor contact with the socket, the power supply is broken first, and the voltage is stable. 2. Next, it is necessary to eliminate other factors that cause the compressor to not start, such as adjusting the thermostat knob to the stop point, temperature control failure, poor installation or damage of the starting protector, etc. 3. After the above problems are ruled out, it is likely that the compressor has been damaged.

Suggested solutions: 1. If it is caused by the failure of the power supply or poor contact, you only need to unplug the power supply, replace the power cord in time, and plug it back in after replacing it, so that it can be restored to the normal refrigeration state. 2. After eliminating the power supply problem, if it is caused by the damage of the compressor, and the refrigerator has no sound and does not refrigerate, it is necessary to contact professional maintenance personnel in time to determine the problem after on-site inspection, and then repair the compressor or replace the coil, which can solve this problem.

3. Then if the thermostat is faulty or damaged, this problem is generally not recommended to be solved by yourself, and it needs to be replaced or repaired under the operation of professionals, and it can be restored to the normal refrigeration state after repair.

1. What is the reason why the refrigerator is not cold? 1.The compressor and accessories are broken.

2.Refrigeration pipes are clogged.

3.Refrigeration pipe leakage.

4.The grid voltage is too low. The refrigerator does not start properly.

Second, the refrigerator has a sound not cold reason solution. First of all, check if the light in the refrigerator is on, if it is on, check the temperature regulator, first turn it off, after cutting off the power for 30 minutes, put an ear on the side of the refrigerator, slowly adjust the temperature regulator from 0 to 7, and listen carefully to whether the temperature regulator has a tartar.

sound, if there is no sound, the temperature regulator will be broken. If there is, continue to listen to the compressor if it starts, and if it starts, the sound continues to hum, then the refrigerant. Leak.

1. It is very likely that in terms of connecting the refrigerator power supply, there has been an abnormal power supply, or the power cord is damaged, and in the absence of normal power supply, the refrigerator will have the problem of no sound and no refrigeration. 2. There are also because the power supply is normal, but the compressor fails, and after the failure, it is easy to cause the compressor to not run and not refrigerate. 3. In some cases, the windings of the motor may be burned, which is also easy to lead to the problem that the refrigerator has no sound and does not refrigerate.

Suggested solution: 1. Check whether the power supply connected to the refrigerator is in a normal state of power supply, or because the power cord has been damaged and the power supply needs to be unplugged, replace the bad power supply in time, and re-insert the power supply, so that the compressor can start normally before it can be refrigerated. 2. If there is a fault in the compressor itself, there is no way to start it after plugging in the power supply, it is recommended to unplug the power supply first, contact professional maintenance personnel in time for on-site inspection, and timely repair and replacement can be solved after understanding the problem.

3. If the motor is burned out because of the winding, there is no way to solve it, and the motor winding can be repaired or replaced with a new winding under the operation of professionals, which can be restored to the normal refrigeration state.

1. First of all, check whether the plug of the refrigerator has been plugged in, if the plug is not plugged in, it will not be powered on, which will lead to this phenomenon. 2. The compressor of the refrigerator is faulty, and once the compressor fails, it will also lead to this phenomenon. 3. The fuse in the refrigerator is burned out.

4. The temperature in the refrigerator has reached the set temperature, therefore, the compressor in the refrigerator cannot work, resulting in this phenomenon.

Suggested workaround:

If the refrigerator's socket is not plugged in properly, just plug the plug into the corresponding socket, and the refrigerator will run.

If the compressor in the refrigerator fails, you need to find a professional maintenance personnel to repair the compressor, or replace the compressor of the same model, so that the refrigerator will return to its normal state.

If the fuse in the refrigerator is blown out, then you need to replace the fuse in the refrigerator, then plug in the refrigerator to see if the refrigerator has been restored to the operating state.

You can also adjust the temperature controller in the refrigerator and observe whether the refrigerator is running. If the refrigerator still has no sound and does not refrigerate, it is necessary to find a professional to check and repair it at this time.

1. The capillary of the refrigerator may be blocked; 2. It may be that the refrigerant in the refrigerator has run out or leaked; 3. It may be that the compressor of the refrigerator has an aging fault.

Suggested workaround:

1. Check whether there is heat at the exit, remove the capillary or remove the dirty stuff, there are many ways to remove it, so I won't introduce it too much here. If the refrigerator has been used for a long time, check and dispose of it regularly.

2. It may be that the refrigerant in the refrigerator has run out and there is a leakage. Power on the refrigerator for about 3 5 minutes, then turn off the power and listen to the sound of water running inside. In the absence of the sound of water flowing, it means that the refrigerator has run out of refrigerant, or there is a leak that causes the refrigerator to heat up and not refrigerate.

At this time, the refrigerator should be sent to the manufacturer's after-sales department, or contact the relevant after-sales personnel for maintenance.

3. It may be that the compressor of the refrigerator has been used for too long and has failed, and the output buffer pipe in the refrigerator compressor has a break, although it is still working normally at this time, it is not refrigerated. Disassemble the case and replace it with a new buffer tube to see if it can still be used properly.
