Sometimes the refrigerator makes clicking or popping sounds that we don't know about, but the reason for these sounds is the usual popping sounds, which do not cause any problems with the refrigerator at all. There are other types of refrigerators that do not emit the sound as well.
But this means that it is the nature of the refrigerator, many people ask about this reason, whether the clicking sound is normal or not, for this reason we will mention to you the solution to this problem through this article, follow us.
Are clicking sounds in the refrigerator motor normal?
In fact, normal refrigerator operation can cause some noise and loud noise, as all refrigerators contain parts and components that contract or expand due to changes in temperature.
That is, before the refrigeration circuit operates, the refrigerator components are in a (relatively) hot environment, and when the refrigeration circuit operates, cold air is produced, which leads to a change in the climatic conditions in which the refrigerator components are located.
Also when you turn off the defrost heater, you will hear noises like those from a refrigerator or freezer.
These sounds are normal and nothing to worry about unless the sound is constant or changes in a strange way.
How to troubleshoot and find out the cause of the noise in the refrigerator (popping or crackling)?
If you suspect that the noise in your refrigerator is not the normal, typical sound caused by the refrigeration cycle and the climate change in the refrigerator, try to troubleshoot and resolve the problem by eliminating the possibility of failure of the refrigerator components.
First you need to determine the timing of the sound and see how often the noise is heard. If the popping sound is heard at equal intervals from 1 to 4 times a day, the reason may be the defrost heater turning on and off. This is normal and there is no need to worry.
What makes noise in a refrigerator?
All the different parts and components of a refrigerator contract and expand when the temperature changes.
Also in some refrigerators, when you open the refrigerator ice machines or water dispensers to let water in, you may hear a sound from the solenoid (the refrigerator water inlet valve), which may produce a sound similar to a popping, clicking, knocking, or gurgling sound of refrigerator water.
Also, in some refrigerators, turning the defrost heater on and off can cause knocking, popping, clicking, banging, or gurgling sounds, all of which can result from changing the defrost heater's position from on to off or vice versa.
The reason for the sound is that if there is an ice maker for the refrigerator, when it is working especially when the ejector arm ejects the ice from the mold and when that happens, a crackling sound is heard.
In most refrigerators, the defrost timer may make a clicking sound as the timer turns on the heater, and there is often a clicking sound between turning on and off.
In most refrigerators, the evaporator (freezer) fan is the cause of the noise. If the fan is not installed properly, it may crack, especially with bends. The refrigerator may also react to changes in temperature, causing the fan speed to change, which causes it to make a slight noise.
The temperature control unit turns the cooling unit on and off, and can make a popping sound when it is turned on or off. The movement of the refrigerant (known as Freon, which is not an accurate name) when the compressor (the refrigerator motor) draws in gas and compresses it with a condenser. The sound can sound similar to banging, popping, or gurgling.
Also, in most refrigerators, the evaporator coil cools down after defrosting, which can cause a popping or knocking sound.
Low voltage (weak electricity) connected to the refrigerator will cause the compressor to try to start the refrigerator's cooling cycle, but when it encounters weak electricity, it produces a clicking or tapping sound.
Causes of the gurgling sound inside the refrigerator and how to avoid it?
The refrigerator is one of the most used household appliances in the home, as all family members open and close it several times a day.
For this reason, they are prone to malfunctions after a period of use, and one of the most common of these malfunctions is water leakage.
When a refrigerator makes some noises while operating, it is confusing and many people wonder whether these sounds are normal or indicate a problem.
There are also several things that happen while the refrigerator is running that can cause this noise:
1. Defrost heater
Any refrigerator has a heater called a defrost, which is connected to the evaporator coil to melt ice, so it doesn't build up in the coil and cause insufficient cooling.
For this reason, while this heater is running and stopping, it will make a gurgling sound.
2. Water valve
The gurgling sound could be coming from the valve that supplies water to the refrigerator to operate the water dispenser and ice machine.
3. Cooling circuit
Refrigerators have refrigeration circuits that operate on a specific mechanism where they use Freon gas to produce cold air.
However, when this circuit is operating, some refrigerators make sounds similar to the sound of gurgling water.
Reasons for water leaking from the refrigerator
The sound of water dripping or accumulating at the bottom of the refrigerator may indicate that the refrigerator is suffering from serious problems, such as:
1. Clogged drain holes
Any refrigerator has a refrigeration circuit that can pump cooling air into the refrigerator and freeze food in the freezer, so there is an opening at the back of the refrigerator that drains the water coming from the evaporator through the refrigerator tube.
This is because it reaches the container installed above the engine, which may cause the engine to overheat, as it collects inside and then evaporates, and when this hole is blocked, water accumulates and begins to leak.
2. Do not close the refrigerator door.
When the refrigerator is overfilled, the refrigerator door will not close properly, allowing hot air to enter.
In addition, the refrigerator door may be opened for a long time to put in or take out items, which may cause outside air to enter the refrigerator, causing a malfunction in the cooling circuit and causing water leakage.
3. Damage to the water drain pipe.
The tubes that supply water from the evaporator to the bowl mounted above the motor can crack or become clogged over time, causing water to leak and pool under the refrigerator.
4. Cracked steaming plate
The container on top of the engine is called an evaporator plate, and if a crack occurs in this plate, the water accumulated in it leaks out, which also poses a danger to the engine.
5. Ice maker malfunction
Most refrigerators make ice cubes, so there is a special place for water to enter to make ice cubes, and it also consists of a valve, pipes, and filters.
Also, if any of these elements fail, water leakage will occur.
6. Damage to the outer rubber
If you notice a problem with the compressor, causing the freezer or refrigerator door to close tightly, hot air will enter the refrigerator and drain the water from the refrigerator.
How to prevent water from leaking?
The drain hole can be cleaned by inserting a curved wire, and repeating this process until all the impurities causing the blockage are removed.
There is accumulated dirt between the rubber folds, which prevents the door from closing tightly. The solution is to clean it well and remove all the accumulated dirt.
When the water in the evaporator freezes for a long time until it evaporates, the sediment will collect at the bottom, occupying the volume of the vessel, and the water will slide to the bottom, and the problem ends with cleaning and removing the sediment.
If the steamer has cracks or other problems, it will be replaced with a new one by a maintenance company.
When does the refrigerator motor shut down?
If we unplug the refrigerator for 6 hours, this means that the refrigerator motor is working properly, but there is a reason why it does not turn off. refrigerator motor About work
This usually happens due to frequent opening of the refrigerator, failure to clean the ice regularly, or a problem with the door opening, which could be caused by a technician.
How do I know if my refrigerator is burnt out?
Try not to hear the motor at all. Feel a short circuit somewhere inside the refrigerator.
The motor can also make annoying noises. Food can lose its cooling capacity, and ice in the freezer can turn to water.
How do I know if the refrigerator motor is burned out?
By adjusting the thermostat, ensure the temperature is set to at least 2°C. Touch the side and back of the refrigerator; if you feel heat, this is normal and strongly indicates that the motor is running.
