The refrigerator that hasn t been used for a long time opens and crackles? 15

The line is a little old, it's best to let the professional personnel test, about 200 yuan.

1. The refrigerator emits vibration and noise, the levelness of the refrigerator installation position is poor, there is a gap between the anchor screws of the refrigerator and the ground, and the refrigerant cycle changes when the compressor starts or stops, causing the refrigerator to vibrate and emit vibration and noise. Adjust the anchor bolts of the refrigerator to be in good contact with the ground, and try to keep them as level, and add rubber or foam pads between the anchor screws and the ground to reduce vibration.

2. There is a crash sound when the refrigerator is shut down, and in the middle of the operation of the new refrigerator, the exhaust valve of the compressor is not closed strictly due to low precision, resulting in air leakage, which is superimposed with the braking force of the motor, causing a large impact sound when the refrigerator is shut down, and after the running time is extended, the exhaust valve is no longer leaking, and the reverse thrust of the piston does not exist, so the impact sound of the refrigerator when it is shut down also disappears.

3. This is the sound of thermal expansion and contraction of the condenser and evaporator of the refrigerator or the icing on the surface of the evaporator when heated or cold. It's normal, don't worry.

There are more opportunities to make this sound in the following situations:

1) The internal stress of some refrigerator materials has not disappeared. As the material is used over time, the internal stresses of the material gradually disappear and the possibility of emitting this sound decreases.

2) After the box is just defrosted, the temperature in the box is uneven.

3) When you open the refrigerator door to pick up the goods, the evaporator in the box is heated up suddenly.

4) A few minutes after the refrigerator starts running or is shut down, the temperature of the condenser and evaporator changes greatly.

5) After the refrigerator is used for half a year or a year, due to the running-in of the internal body of the compressor, the gap increases, and the noise also increases.

It means that the compressor cannot be started, and the overheating and overcurrent protector is working. Check whether the starting capacitor is broken, you can replace it with a good one; Either the compressor stalled, this is the need to change the compressor. There is also a possibility that the impedance of the power circuit is too high, check whether the socket is plugged in tightly, and whether the wiring is not in good contact.

The refrigerator will have an automatic temperature control function, after reaching a certain temperature, the energizing switch will be automatically disconnected, when it is higher than a certain temperature, the relay will be engaged, and the sound of suction will be heard.

The voltage is not hungry, the refrigerator will give out fat business from time to time, I think ah uh, the refrigerator is a temperature control appliance, when the temperature reaches a certain length, that is, the specified temperature, it will naturally stop the cycle. This will happen when the temperature gradually changes after a period of time. So this is when the cycle starts again.

The so-called fixed frequency is a refrigerator that works at a fixed frequency. When the refrigerator first starts running, the compressor will run at a specific frequency, when the refrigerator drops to the specified temperature, the compressor will stop running, and then the temperature will slowly rise, when the temperature and the specified temperature reach a certain difference, the compressor will start to run to cool down, and repeat this process. So what we hear is actually the sound of the compressor starting.

This may be the sound of the compressor when the refrigerator is started, and often this sound appears in the fixed-frequency refrigerator, and the inverter will not appear.

The refrigerator always makes a sound, and the refrigerator itself has an engine running in it, so it makes a sound normally.

It is estimated that the sound is caused by a physical change in the thermal expansion and contraction of the system pipes when the refrigerator is working. The refrigerator is working normally, don't worry too much, the refrigerator is still within the warranty period, you can also call the manufacturer's customer service** to contact the door-to-door inspection.

It may be that the refrigerator is faulty, in this case, it is better to ask a professional maintenance personnel to check it to see what is causing it.

The refrigerator makes a popping sound from time to time, which may be caused by the failure of the refrigerator temperature control, the storage of too much food in the refrigerator, and the high temperature of the external environment.

This is the sound of the compressor working intermittently.

A snap is likely to make the refrigerator suddenly lose power.

If the refrigerator is connected to the outside of the additional power-saving device, you can try to adjust the power-off interval shorter, so that the refrigerator can play a role in freezing and refrigeration, if you want to fully achieve the refrigeration effect, remove the external additional power-saving device.

If the refrigerator does not have an external power-saving device and there is a frequent snapping sound, it is likely that there is a problem with the induction setting of components such as the internal temperature control device of the refrigerator, or there is a problem with these components themselves that will cause the refrigerator to automatically lose power.

Normally, when the set temperature is reached, some machines will have when the press stops working.

It is generally normal, and the sound of the mallet rising and shrinking is fine.

The sound of the rotor colliding with the compressor shell at the moment when the compressor starts or stops automatically from time to time due to the unlevel ground!

Adjust the level of the base and the problem will be solved!

When it rings, it doesn't mean that the refrigeration starts or the refrigeration ends", doesn't it mean the moment when the compressor starts or stops automatically from time to time, right?

1. It may be that the refrigerator is placed unevenly, causing the rotor inside the compressor to hit the cylinder, or the sound of the refrigeration pipeline.

2. It may be that the voltage connected to the refrigerator is unstable, resulting in the sound of abnormal compressor operation.

3. It may be that the frost in the refrigerator room is severe, blocking the drainage pipe at the bottom of the back wall of the box.

Effects of a fridge rattle:

1. A kind of noise, which has an impression of family rest.

2. Abnormal noise indicates that the refrigerator or accessories are faulty, affecting normal use.

The solution to the constant rattling of the refrigerator:

1. Put the refrigerator and lay it flat, check whether all four feet are on the ground, or try to put a wooden block on one foot pad.

2. Find an electrician to check the voltage.

3. Check whether the refrigerator room is frosty, if so, unplug the power supply, wait for the frost to melt, the drainage hole is unblocked, and pay attention not to get too close to the drainage hole in the future.

There are many reasons for the noise of the refrigerator, generally it may be due to the refrigerator is not placed properly, it may also be due to the working noise of the compressor, or it may be due to the loose fixing of other parts, and the screws and other fixed parts are given with tools.

After moving the position, wait 30 minutes for the power to be turned on!

This is the compressor starting to work, because the temperature in the refrigerator is higher than the set temperature, and the snapping sound is that the compressor touched the shell at the moment of starting, but this doesn't matter, this is normal.

The sound of the relay should not be that loud. It may be caused by periodic deformation of the inner tank due to temperature changes. It's best to call after-sales service to see.
