Are these noises coming from your refrigerator? It means it's breathing its last. Do this immediately

A refrigerator is an electronic appliance that runs all day, so it's normal for it to occasionally make minor noises. However, sometimes these noises can be the beginning of a serious problem. 

People often ignore these noises, but identifying them early can prevent costly damage. Therefore, it's crucial to understand which noises are normal and which require immediate attention.

Tucking or cracking sounds: Not always a cause for concern.

When the temperature inside the refrigerator changes—such as when the door is opened or closed or during defrosting—plastic and metal parts expand and contract. 

This causes 'tucking' or 'cracking' sounds. This is a completely natural process and is not considered a malfunction. As long as the refrigerator is providing normal cooling, such sounds are not a cause for concern.

Ice Maker Noises: Normal Ice Falling Sounds

In refrigerators with automatic ice makers, ice will periodically form and fall into the container, producing a "thump" sound. The water filling valve then opens, producing a slight buzzing sound for a few seconds. This entire cycle repeats every few hours and is considered completely normal, so there's no need to panic.

Defrost Mode Sounds: The collision of heat and ice

during the refrigerator's defrost cycle can cause a variety of sounds. Melting ice and falling onto the heater can produce a crackling or hissing sound. 

Water flowing can produce a gurgling or bubbling sound. A dripping sound can also be heard as water flows down the drain pipe. This is all part of defrosting and is completely normal.

Compressor Noise: A Sign of a Major Failure

If your refrigerator makes a loud, "noise-inducing" noise or unusual vibrations, it often indicates a problem with the compressor. It's possible that a part inside the compressor is loose or the screws aren't properly fitted. 

In such a situation, it's essential to call a mechanic immediately, as if the compressor is completely damaged, repairing the refrigerator can be expensive, and purchasing a new refrigerator may be the better option.

If too much ice accumulates in the freezer, it hits the evaporator fan and produces a loud buzzing sound. This situation often occurs when the refrigerator door is left open or hot items are kept inside. 

It can be fixed at home – turn off the refrigerator and leave the freezer door open for 7–8 hours. But if the same noises start coming again, it is a clear sign of a malfunction in the auto-defrost system.

Loud humming or clicking: The compressor is on its last legs.

A mild humming sound is normal, but if it becomes too loud and the refrigerator isn't cooling properly, the compressor may be overloaded. 

Sometimes a clicking sound may also occur, indicating the compressor is overheating and shutting down repeatedly. First, clean the condenser coils. If the condition persists, it's time to replace the compressor or get a new refrigerator.
