Why does the refrigerator make an abnormal noise every once in a while while it is running?

There is an abnormal sound every once in a while when the refrigerator is running, first check whether the refrigerator compressor is stuck inside? The second question is whether the compressor is lacking liquid? And is there a leak in the compressor lines?

Do you mean that the abnormal noise is that the refrigerator starts every once in a while, which is very normal, because when the refrigerator temperature reaches a certain level, the motor will automatically stop. When the temperature is low, it will automatically restart.

When running as above, there will be a certain impression every once in a while, so I think this should still need to be paid attention to, otherwise, this may be a state of a period of operation, so I think this should be repaired to the refrigerator.

The reason why the fridge rings every once in a while:

The refrigeration program of the refrigerator is determined by the refrigerator thermostat, when the user adjusts the thermostat to 3-4 gears, the refrigerator starts to start the working program for refrigeration due to insufficient internal temperature. When the internal temperature is slowly reached by the system cooling to the temperature set by the user, it starts to stop working and is in standby mode.

However, due to the refrigerated food in the refrigerator and the sealing of the refrigerator, the temperature inside the refrigerator will slowly rise, when the internal temperature reaches the maximum temperature of the user's set temperature. The refrigerator starts the refrigeration program again, and when the refrigerator starts and stops, there will be a sound of the compressor working and stopping.

This cycle goes on and on, so the user will hear the refrigerator ring every once in a while, and that sound is a normal sound when the compressor starts or stops.

Note: The compressor of the refrigerator is supported by four springs to prevent its vibration and noise from being too loud, and it is also convenient for the refrigeration oil to cool down its motor. The motor will have a large rotation distance when starting, which will lead the electric grip to shake on the spring when starting or stopping, and sometimes this shaking will occasionally cause noise to hit the housing, which is a normal phenomenon.

There are many common reasons why your refrigerator makes an abnormal noise, and here are some possible explanations:

Compressor sound: The largest part of the refrigerator is the compressor, if you can hear a continuous low-frequency hum or whistling sound after the refrigerator is turned on and off, then it is most likely caused by the compressor running. This sound is usually more noticeable during initial installation or momentary turn-on.

Fan failure: Some parts of the refrigerator need to be used for air flow and cooling through the fan, if there is a problem with the fan, resulting in the air not flowing up or foreign objects stuck, etc., it will make a whirring sound or periodic tapping sound.

The compressor is one of the most important components in a refrigerator, and if something goes wrong with it, it can cause the refrigerator to make noise. For example, when the compressor is turned on or off, there may be a humming or clicking sound. This could mean that the compressor needs to be repaired or replaced.

The fan in the refrigerator is responsible for circulating the air and keeping the temperature even. If there is a problem with the fan, it may cause noise. For example, when the fan speed is unstable or rubs against other components, it may make a noisy sound. This may require the fan to be repaired or replaced.

1.It is normal for the refrigerator to ring every once in a while, because when the refrigerator reaches the set problem, the compressor will stop working to save energy, and when the temperature in the refrigerator rises, the compressor needs to start working again.

2.Under normal circumstances, it runs for a while or so every ten years, and it is normal to have a little noise, and the brand is a little lighter, and the sound of the bad brand is louder. But it's not normal if it's very loud.

3.If there is a loud continuous vibration sound. It may be that the ground where the refrigerator is placed is uneven or unstable, which is also a common cause of noise generated by refrigerators.

Solution: Pat or push the refrigerator with your hands first, listen carefully to whether the abnormal noise has changed, and then observe whether the refrigerator is flat, if not, twist the adjusting screw at the bottom of the refrigerator, adjust the height, when the adjusting screw touches the ground, the four feet touch the ground is the best state. Or put the uneven parts with plastic blocks, and the problem can be solved.

In addition, there is another reason - there are items on top of the refrigerator. The refrigerator and the items placed on top of it resonate when the motor starts, causing noise. Removing the items on the top of the refrigerator will prevent it from resonating and the noise will naturally be eliminated.

Hello, your refrigerator makes a noise from time to time because your refrigerator is a fixed-frequency refrigerator, and the sound is generated by the compressor of the fixed-frequency refrigerator when it starts. If you want to avoid it, choose to buy an inverter refrigerator. Inverter is also the development trend of refrigerators in the future. Fixed frequency refrigerators.

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.

The reasons why the refrigerator clicks when it starts up are as follows. The refrigerator connection current is too large, and the compressor can't stand it. There was a lag on the working equipment of the refrigerator.

Refrigerator starter capacitor device damaged; The refrigerator compressor is damaged and does not work properly. There was a problem with the refrigerator's circuitry, causing the circuit to reflow. Here's how to fix it:

Confirm the size of the current in the house circuit and adjust it to the appropriate current for the refrigerator circuit. Please turn the refrigerator back on and try it. If there is a problem with the internal equipment of the refrigerator, please go to the relevant after-sales department for maintenance and inspection.

The refrigerator has a national standard in terms of noise, as long as the sound does not exceed 45 decibels, it is qualified. If the refrigerator is too noisy or there is no sound in the past, as long as there are several reasons (faults that can only make a "buzzing" sound) 3354 does not affect the cooling, you don't need to worry about the noise problem. The refrigerator must be placed horizontally on the floor, it is best to put it away, shake the refrigerator with your hands, and do not shake it easily.

If it is uneven, the compressor will cause the refrigerator to move and vibrate together when it is working. The lower refrigerator feet slap the ground. Because of the fast frequency, what we hear is a "buzzing" sound.

The refrigerator feet can generally be adjusted, so it is enough to adjust the square height and keep it level. If one foot is broken, you can use something like a rubber sheet to cushion it. The top of the refrigerator is prone to this problem.

When a relatively light thing is placed on the top of the refrigerator, such as plastic bags, packaging boxes, etc., the compressor will resonate when it is working, which will eventually cause the thing to constantly slap on the top of the refrigerator, and eventually make a "buzzing" sound, which is the most common. Especially when moving the refrigerator for post-processing – if there is no refrigerator box or the carrier is unprofessional, the pipe may come loose.

The most susceptible pipe to loosen is next to the compressor, called the "exhaust pipe", which is U-shaped. After the compressor is turned on, the exhaust pipe begins to vibrate, and if the "buzzing" sound loosens any line of the 3354, it will make a "buzzing" sound, but the exhaust pipe is easy to loosen, so take it out specifically to say. To solve the pipe resonance problem, the refrigerator must be disassembled.

Repairs are generally not recommended. In general, a humming sound inside means that the refrigerator compressor continues to run with no downtime. This may be because the thermostat is damaged, the control temperature cannot be recognized, and the compressor continues to work without a shutdown signal, so a new thermostat needs to be replaced.

If the buzzing sound occurs at some point on the outside, it may be a resonance caused by uneven placement of the refrigerator or placing something on top of the refrigerator. The four corner screws on the bottom can be adjusted to keep the refrigerator vertically level. It is also possible to reduce the sound by putting rubber on the bottom of the refrigerator to reduce vibration transmission.

Since the compressor is still running, an abnormal sound from the refrigerator is generated. The internal cause is a loose pipe in the refrigerator. After buying a refrigerator and moving it home, the plumbing may become weaker due to the carelessness of the workers.

You can ask a professional to open the case for repairs. If the refrigerator is not installed correctly, it can also cause noise. The inside of the spring cannot be positioned properly due to its unevenness.

Just adjust the height of the bottom screw slightly. We may be faced with another situation to a greater or lesser extent, and that is that the refrigerator is used as a storage place and small items are always placed on it. Over time, more stuff builds up and puts pressure on the compressor.

Remove the things mentioned above and fix them.

During the use of the refrigerator, the motor inside runs non-stop, and it is normal to make a sound, which is a normal situation, and there is no need to worry about it at all.
