LG Refrigerator Noise That Stops When the Door is Opened
Written ByZein
Have you ever opened your LG refrigerator door only to hear a sudden silence when the noise you’ve been hearing instantly stops? It can be annoying and confusing, especially when the noise seems to appear randomly or only under certain conditions. But no worries — you’re not alone, and there are simple explanations and fixes for this. Let’s dive in and figure out what’s going on and how you can fix it in no time!
Possible Causes of LG Refrigerator Noise When the Door is Closed
Refrigerator noise can be super frustrating, especially when it seems to appear without warning. If you’ve noticed that your LG fridge starts making strange sounds but stops when you open the door, you might be wondering what’s causing it. Let’s break down some common causes and potential reasons behind this odd behavior.
1. Compressor Running
The compressor is like the heartbeat of your refrigerator. It works tirelessly to circulate refrigerant throughout the fridge and freezer, maintaining the internal temperature. When the fridge door is closed, the compressor is often active, and this can sometimes generate a buzzing or humming sound. However, once the door is opened, the fridge’s internal temperature briefly changes, and the compressor may shut off temporarily, which could explain why the noise stops.
Why this happens: When the fridge door is closed, it’s maintaining a steady internal temperature, and the compressor needs to stay on. Opening the door changes the temperature slightly, triggering the fridge’s thermostat to stop the compressor for a short period. When the compressor restarts, the noise might begin again.
How to fix it: This kind of noise is usually normal, and the compressor’s behavior isn’t something you need to worry about. But if the noise is unusually loud or bothersome, you might want to check if the compressor is working properly or if it’s time for maintenance. Ensuring the fridge has good airflow and isn’t overloaded can also help minimize the sound.
2. Evaporator Fan Problems
The evaporator fan is another key part of the refrigerator’s cooling system. Located in the back or at the top, this fan helps circulate cool air throughout the fridge and freezer. If you’re hearing a buzzing or whirring noise, it could be coming from this fan. The noise may stop when you open the door because the airflow is temporarily disrupted or the fan’s motor has to adjust.
Why this happens: The evaporator fan works hard to distribute cool air, and when the door is shut, it often runs at full speed to keep everything cold. Opening the door can cause the air pressure to change, affecting the fan’s operation. The fan may stop running temporarily, causing the noise to stop too.
How to fix it: Check if the evaporator fan is clean and free of ice buildup. Ice or dirt can cause the fan to struggle and make more noise. If the fan blades are damaged or the fan motor is malfunctioning, you may need to replace the part. Cleaning the fan regularly can also help it run smoothly and quietly.
3. Defrost Heater Cycle
Fridges with a defrost cycle often make some noise when the heater turns on. The defrost heater melts any ice that forms on the evaporator coils, preventing ice buildup and maintaining optimal cooling. The heater usually runs on a timer, and when it activates, it can create a cracking or sizzling noise as ice turns to water. You might hear this noise when the door is closed, but as soon as you open the door, the temperature change can cause the heater to turn off, stopping the noise.
Why this happens: If your LG fridge has an automatic defrost cycle, the defrost heater might be the culprit. When the fridge door is closed, the heater works to melt any ice buildup, and you hear the noise as part of the melting process. Opening the door temporarily stops the cycle, causing the noise to stop as well.
How to fix it: If the noise is coming from the defrost heater, it’s usually nothing to worry about. The noise is just a part of the normal defrost process. However, if the noise becomes loud or frequent, it could be a sign of an issue with the heater, thermostat, or defrost timer. In that case, you may need to replace the faulty component to prevent excessive noise.
4. Ice Maker Operation
If your LG refrigerator is equipped with an ice maker, it could be contributing to the noise you’re hearing. Ice makers operate using a motor to move water through the system and produce ice cubes. When the door is closed, you might hear the sound of water filling the ice tray or the motor running. But once the door is opened, the mechanism is temporarily interrupted, and the noise stops.
Why this happens: The ice maker’s cycle involves water flowing into the tray, freezing, and then the motor moving the tray to release the ice. These motions create a sound that can be pretty noticeable, especially in a quiet kitchen. Opening the fridge door can disrupt the cycle, causing the noise to stop momentarily.
How to fix it: If the noise is just from the normal operation of the ice maker, there’s no need to worry. However, if the noise is excessively loud or the ice maker isn’t functioning properly, check if the water line is clogged or if there’s ice buildup that might be interfering with the system. Clean out the ice maker regularly, and make sure the water line is clear.
5. Water Line or Valve Noise
For refrigerators with a water dispenser or ice maker, the noise could be coming from the water line or valve. The water supply valve opens and closes as the fridge needs water for its ice maker or water dispenser. When the door is closed, the valve is likely open, but when you open the door, the temperature change can cause the valve to momentarily close, stopping the noise.
Why this happens: When the water valve operates to fill the ice maker or provide water for the dispenser, it can make a clicking or humming noise. This noise may stop when you open the door because the water pressure is momentarily affected, and the valve temporarily closes.
How to fix it: If the noise is coming from the water valve, you might want to check for any blockages in the water line. Sediment buildup or kinks in the line can cause irregular sounds. Ensuring the water filter is clean and replacing it regularly can also help reduce noise and improve water flow.
6. Vibration from Items Inside the Fridge
Sometimes the noise you hear isn’t even from the fridge’s mechanical parts; it could be from something inside the fridge. If there are items inside that are too close to the sides of the fridge or freezer, or if they’re not secured properly, they can vibrate when the compressor or fan turns on. This can lead to an irritating noise that stops when you open the door, as it changes the airflow and stops the vibrations.
Why this happens: If you have a lot of items in the fridge or if some items are positioned poorly, they can rattle or vibrate when the cooling system kicks in. When you open the door, the airflow changes, and the vibrations may stop because the compressor or fan may temporarily stop working.
How to fix it: Rearranging items inside the fridge to ensure they’re not touching the sides or stacked improperly can help. Make sure to distribute weight evenly and avoid overloading the fridge. Check if items like bottles, jars, or cans are placed in a way that could cause them to rattle when the fridge is running.
How to Fix the Issue of Noise Stopping When the Door is Opened in LG Refrigerators
While many of the causes of this noise are normal, there are some ways you can troubleshoot and possibly fix the issue yourself. Let’s explore the steps you can take to minimize or eliminate the noise completely.
1. Check for Proper Leveling
The first thing you should do is check if your refrigerator is properly leveled. It might seem like a small thing, but it actually plays a big role in how smoothly your fridge runs. If the fridge isn’t level, it can cause it to vibrate or make more noise than usual.
This is because when the fridge isn’t sitting on a flat surface, the parts inside — like the compressor and fan — can become unbalanced, making it work harder. When the fridge door is closed, this extra strain could cause noise. Opening the door can sometimes change the balance slightly, which could explain why the noise stops.
How to fix it: To level your fridge, you’ll need a simple level tool, which you can get at most hardware stores. Once you have the level, place it on top of your refrigerator to see if it’s even. If the fridge is tilted, adjust the leveling legs at the front of the fridge. These legs are designed to make the fridge sit flat.
You can turn the legs to raise or lower them, depending on where the fridge is leaning. After making adjustments, double-check the level again to make sure it’s perfectly balanced. A well-leveled fridge runs much more quietly and efficiently, and this might solve the noise problem altogether.
2. Clean the Evaporator Fan
Next, it’s important to check the evaporator fan. This fan is responsible for circulating cool air throughout your fridge. Over time, dust, dirt, or even ice buildup can gather on the fan blades, making the fan work harder and create more noise.
The fan’s motor may also struggle if it’s dirty, which is why it could make buzzing, whirring, or rattling sounds. When you open the door, it might temporarily stop the fan or disrupt the airflow, which is why the noise disappears. But once the door is closed again, the fan starts working harder, and the noise returns.
How to fix it: First, unplug the fridge to make sure it’s safe to work on. Once the fridge is unplugged, remove any food items from the fridge to make the process easier. The fan is usually located at the back or the top of the fridge, so you may need to remove some panels or shelves to access it.
Once you find the fan, check for any visible dirt or ice buildup. Use a soft cloth or sponge to clean the blades carefully. If there’s a lot of dust, you can use a can of compressed air to blow it off. If you notice that ice has built up around the fan, it might indicate a bigger issue with the defrost system, and you should let the ice melt away before cleaning.
After cleaning, make sure the fan blades can spin freely without obstruction. Once the fan is cleaned, plug the fridge back in and see if the noise stops or is reduced.
3. Inspect the Ice Maker
If your LG fridge has an ice maker, it might be the source of the noise. Ice makers have motors and moving parts that can make various sounds, like humming or clicking, as they work. When the fridge door is closed, the ice maker might be in the middle of making ice or filling the tray with water.
You may hear the noise from the motor or the water valve as it runs. But when you open the door, the system gets interrupted, and the noise temporarily stops. This is a pretty common issue with ice makers, and it’s usually nothing to worry about.
How to fix it: First, make sure the ice maker is turned off. You can usually do this by pressing a button on the control panel or by switching the ice maker off. Let the system fully stop before you start checking it.
Once the ice maker is off, open the freezer door and take a look at the ice tray. If you see any large blocks of ice stuck in the tray or around the mechanism, gently break them up. Ice buildup can make the ice maker’s motor work harder, which creates more noise.
Also, check the water line connected to the ice maker for any kinks or blockages. If you find any, straighten the line and clear any obstructions. You should also make sure that the ice maker’s motor is working properly. If the noise continues after these steps, it could mean the motor is malfunctioning, and you may need to replace the ice maker motor or call a professional.
4. Check the Water Valve
For refrigerators that have a water dispenser or ice maker, the water valve can sometimes make noise. The valve opens and closes to supply water to the ice maker and water dispenser, and sometimes it can make a clicking or buzzing sound when it’s operating.
When the door is closed, the valve might be open, but once you open the door, the temperature change can cause the valve to close temporarily, stopping the noise. If you think the water valve might be the cause of the noise, it’s important to check it.
How to fix it: First, you’ll need to turn off the water supply to the refrigerator. This is usually done by turning a valve on the water line that connects to the fridge. Once the water supply is off, locate the water valve. You may need to remove some panels or parts of the fridge to access it.
Look for any signs of sediment buildup, which can block water flow and cause the valve to make noise. You can clean the valve using a soft cloth or sponge, but be gentle to avoid damaging any delicate parts. If the valve looks corroded or damaged, you may need to replace it with a new one.
After cleaning or replacing the valve, turn the water supply back on and test the fridge to see if the noise has been reduced or eliminated.
5. Rearrange Items Inside the Fridge
Sometimes the noise you hear isn’t coming from the fridge’s mechanical parts at all. It could actually be caused by things inside the fridge. If you have a lot of heavy items in the fridge or if some things are leaning against the sides, they can vibrate when the compressor or fan turns on.
These vibrations may stop when you open the door because the air pressure is slightly different. Once the door is closed, the vibrations start again, and the noise continues.
How to fix it: Take a look inside your fridge and check for any items that could be causing vibrations. Move any bottles, jars, or cans away from the sides of the fridge. It’s also a good idea to make sure that nothing inside is leaning or stacked in a way that could cause it to shift and rattle.
If you have any glass jars or bottles, make sure they’re not touching each other, as they can make noise if they’re clinking together. When you open the door, the airflow inside the fridge changes, and this can temporarily stop any vibrations. By rearranging the items, you’ll reduce the chance of those annoying rattling noises when the door is closed.
6. Consider Professional Help
If you’ve tried all the above steps and the noise still hasn’t stopped, it might be time to call in a professional. Sometimes, the cause of the noise could be something more complicated, like a malfunctioning compressor or a failing fan motor.
These are parts that are harder to fix without professional knowledge or tools, so it’s best to get expert help. An experienced technician can diagnose the problem and recommend the best solution, whether it’s a simple repair or a replacement part.
How to fix it: If you think the issue is more serious or the noise has become unusually loud, it’s time to contact a licensed LG technician. They have the knowledge and tools to properly diagnose issues with the compressor, fan, or other parts of your fridge. They can also perform any necessary repairs or replacements to get your fridge back to working quietly and efficiently.
I hope you found this guide helpful in understanding why your LG refrigerator makes noise when the door is closed and why it stops when you open it. Most of the time, the noise is normal and part of the fridge’s operation, but if it’s bothering you, there are easy ways to troubleshoot and fix it.
