Microwave Making Loud Noise: 7 Causes and Their Fixes!

Anyone who has ever used a microwave knows how handy they are for heating up food quickly. But what happens when your microwave starts making loud noise? It can be pretty alarming! A noisy microwave could mean something’s not right, and you might be wondering if it’s time for a repair. In this article, we’ll explore the common reasons for a microwave making loud noise and what you can do about it. Let’s dive in and find out more!

Common Causes of Microwave Making Loud Noise

Microwaves are great for cooking food quickly. However, sometimes they make loud noises that can be annoying. Here are some common reasons why microwaves make loud sounds.

1. Turntable Issues

Many microwaves have a turntable inside. This part helps to cook food evenly. If the turntable is not placed correctly or is damaged, it can hit the walls of the microwave and make loud noises. Make sure the turntable is sitting well on its base.

2. Fan Problems

Microwaves have fans that help cool the machine while it works. If the fan is blocked by dirt or food, it can make loud grinding or rattling sounds. Cleaning the fan area can help reduce the noise.

3. Magnetron Noise

The magnetron is the part that makes microwaves. Sometimes, this part can make humming or buzzing sounds. This noise can be normal, but if it gets too loud, it might mean there is a problem. It is best to check if the magnetron needs fixing.

4. Loose Parts

Over time, some parts of the microwave can become loose. This includes screws or other pieces. Loose parts can rattle and create noise when the microwave is on. Tightening these parts can help stop the noise.

5. Food in Container

If food is in a container that is not microwave-safe, it can create strange noises. The container might vibrate or even crack under heat. Always use microwave-safe containers to avoid this problem.

6. High Power Settings

When the microwave is set to a high power level, it can make more noise. This is because the machine is working harder. Lowering the power setting can help reduce noise while cooking.

7. Age of Microwave

Like all machines, microwaves can wear out over time. Older microwaves might make more noise as parts start to break down. If your microwave is very old and noisy, it might be time to consider getting a new one.

Understanding these common causes can help you keep your microwave working well and your kitchen quiet.

How to Fix Microwave Making Loud Noise: Step-by-Step Guide

If your microwave is making loud noises, it can be annoying. Luckily, there are some simple steps you can take to fix the problem.

1. Check the Turntable

The first step to fix a noisy microwave is to check the turntable. The turntable is the round plate inside the microwave that spins. It helps to cook food evenly by moving it around. Sometimes, the turntable can make noise if it is not placed correctly.

To check the turntable, start by opening the microwave door. Carefully remove the turntable from the microwave. You can lift it straight up off the base. Look at the bottom of the turntable for any cracks or damage. If you see any cracks, it may need to be replaced. You can buy a new turntable from a store or online.

Once you have checked for damage, put the turntable back on the base. Make sure it sits evenly and securely. It should not wobble or move around. Spin it with your hand to see if it rotates freely. If it feels stuck or makes noise while spinning, there may be a problem with the base or the turntable itself.

After placing the turntable back, close the microwave door and run it for a short time. Listen closely to see if the noise has stopped. If the noise continues, the turntable might not be the only issue. You may need to check other parts of the microwave.

2. Clean the Fan Area

The second step in fixing a noisy microwave is to clean the fan area. The fan is an important part of the microwave. It helps to cool down the machine while it is cooking. If the fan is dirty or blocked, it can make loud grinding or rattling sounds. Cleaning the fan can help reduce these noises.

First, unplug the microwave to ensure your safety while cleaning. It is very important to make sure the microwave is not plugged in when you are cleaning inside. This helps prevent any accidents. After unplugging, look for the fan area. The fan is usually located at the back or the bottom of the microwave.

To clean the fan, you may need to remove a cover. Use a screwdriver to carefully take off any screws that hold the cover in place. Once the cover is removed, you can see the fan. Look for dust, food particles, or anything that may be blocking the fan. Use a soft cloth or a brush to gently clean the fan blades. Make sure not to damage the fan while cleaning.

After cleaning, replace the cover and screw it back into place. Then, plug the microwave back in. Run it for a short time and listen for any changes in noise. If the noise has decreased, you have successfully fixed the problem. If the loud noise continues, it may be time to look at other parts of the microwave.

3. Listen for Magnetron Noise

The third step in fixing a noisy microwave is to listen for magnetron noise. The magnetron is a very important part of the microwave. It creates the microwaves that cook your food. Sometimes, the magnetron can make humming or buzzing sounds. Some noise from the magnetron is normal, but if it gets too loud, it could mean there is a problem.

To check for magnetron noise, start by plugging in the microwave and running it with a cup of water inside. Listen carefully to the sound it makes while cooking. If you hear a loud buzzing or humming noise, it may be coming from the magnetron. You can also gently touch the outside of the microwave to feel for vibrations. If you feel strong vibrations, it is a sign that something may be wrong.

If the noise is not too loud, it may be okay. However, if it is very loud or gets louder over time, you should consider calling a technician. A professional can help check if the magnetron needs repairs or replacement. Fixing or replacing the magnetron can be complicated, so it is best to let an expert handle it.

In some cases, the magnetron may make noise due to the power setting of the microwave. If you are using a high power setting, try lowering it to see if the noise reduces. Sometimes, a simple change in the power level can make a big difference in how the microwave sounds.

Listening for magnetron noise is an important step in troubleshooting your noisy microwave. If the noise is too loud or unusual, don’t hesitate to seek help from a professional. They can provide the best solutions to get your microwave working quietly again.

4. Tighten Loose Parts

The fourth step in fixing a noisy microwave is to check for loose parts. Over time, microwaves can have parts that become loose. This is especially true if the microwave is older or has been used a lot. Loose parts can rattle and create annoying noises while the microwave is running.

To start, unplug the microwave to ensure safety while you check for loose parts. Look at the outside of the microwave for screws or any parts that may not be tight. Use a screwdriver to tighten any screws that seem loose. Pay close attention to the area around the door, the control panel, and the back of the microwave.

After checking the outside, open the microwave door and look inside. Check for any loose components inside the microwave cavity. Some microwaves have screws that hold the turntable support and other parts in place. Tighten these screws if needed.

Once you have tightened all the screws and parts, plug the microwave back in. Run it for a short time to see if the noise has stopped. If it is still making noise, it could be due to other issues, but tightening loose parts often helps reduce or eliminate rattling sounds.

Regularly checking for loose parts is a good practice to keep your microwave in good working condition. It can help prevent future noise problems and extend the life of your appliance. If you notice that parts continue to become loose, it might be a sign that there is a more serious issue with the microwave. In that case, consider consulting a professional.

5. Use the Right Containers

The fifth step in fixing a noisy microwave is to use the right containers. Not all containers are safe for use in microwaves. If you use containers that are not microwave-safe, they can vibrate, rattle, or even crack while cooking. This can create loud noises and may damage your microwave.

To ensure you are using the right containers, look for labels that say “microwave-safe.” These containers are designed to handle the heat and energy of microwaves. Glass, ceramic, and certain plastics are often good choices. Avoid using metal containers, as metal can spark and cause damage to the microwave.

When placing food in the microwave, make sure the container fits well on the turntable. If the container is too large or heavy, it can cause the turntable to struggle, leading to noise. Try to use smaller, lighter containers whenever possible.

While cooking, check the container periodically to see if it is shaking or moving. If you notice that the container is making noise, stop the microwave and take a look. It may be best to switch to a different container that is more stable.

Using the right containers not only helps to reduce noise but also ensures your food cooks evenly and safely. If you are unsure whether a container is microwave-safe, it is better to choose a different one. Always prioritize safety to avoid any accidents or damage to your microwave.

6. Adjust Power Settings

The sixth step in fixing a noisy microwave is to adjust the power settings. Sometimes, the power level can affect how loud the microwave is while it is cooking. If you are using a high power setting, the microwave may work harder and produce more noise. Lowering the power setting can help reduce the noise while still cooking your food properly.

To change the power setting, look for the power level button on your microwave. This button is often labeled as “Power” or “Power Level.” Press this button to cycle through different settings, usually ranging from low to high power. Try setting the microwave to a lower power level, such as medium or medium-low.

Once you have adjusted the power level, run the microwave for a short time with food or a cup of water inside. Listen to see if the noise has decreased. Often, using a lower power setting can help quiet the microwave while still effectively cooking or reheating your food.

If lowering the power setting helps reduce noise, you can continue to use this method in the future. It is also a good idea to keep the power level lower when cooking foods that do not require high heat. This can help prolong the life of the microwave and keep it running smoothly.

7. Consider Age and Repairs

If your microwave is old and still making loud noises, it might be time for a new one. However, if it is relatively new, consider contacting a repair service. They can help diagnose and fix any issues with the microwave.

I hope this guide helps you fix your noisy microwave. By checking the turntable, cleaning the fan, and using the right containers, you can make your microwave quieter. If the noise continues, remember to look for loose parts or adjust the power settings. If everything else fails, consider getting a new microwave. Enjoy cooking in peace!
