Microwaves are one of the most popular kitchen appliances around. When people buy a microwave oven, they do not really know what to expect from the appliance. It is all about convenience and speed. In this age of instant gratification, microwaves are an ideal solution for those who want their food as quickly as possible without having to wait long hours in queues at restaurants or cafes. Other than that, many choose to have one because it can save them costs on electricity bills since microwaves use less energy compared with regular stoves and ovens.
But do they know how much sound a microwave makes? If you live in an apartment or house where noise travels through walls and floors, you probably hear your neighbors’ microwaves every day. This can be frustrating if it keeps you up at night or irritates you during meal prep. I heard my neighbor making popcorn last night, is there any way for me to stop hearing these sounds? Luckily, we have tips on how to reduce the amount of sound that comes from your own device!
Why Does the Microwave Make Much Noise?
A microwave is a kitchen appliance that uses radio waves to produce heat inside the food. It works by bombarding the liquid water molecules in your meal with high-intensity microwaves, causing them to vibrate and generate heat which cooks or warms your food from within. The issue of noise usually comes up when you open it while cooking because some parts still remain cool enough for soundwaves to travel through.
Even worse, microwaves also vibrate on the surface where they stand because of the internal mechanism (more specifically, the magnetron) that produces heat and cooks your food. This is why it is not recommended to install a microwave oven in high-traffic areas, such as hallways or common areas, as it will amplify the sounds it emits.
But, these are not the only reasons why your microwave can be so loud. Let’s investigate such reasons in detail.
The Drive Motor Noise
The drive motor sits in the back of your microwave oven and is responsible for spinning your food during cooking. It creates a humming noise that can be annoying if it penetrates through walls or ceilings into adjacent rooms. The best way to prevent this from happening is by placing a large piece of metal between the exterior wall and the unit itself, which will absorb vibrations before they reach other areas in your house.
The magnetron is the component inside your microwave that creates heat and cooks food. It makes a humming noise when working, which can be slightly noticeable in quiet rooms with nothing to mask it. When the magnetron does not work properly it starts making louder humming or buzzing noises. The best way to reduce such noise from escaping is by adding insulation around this area of the device or change the magnetron for a new one.
The Drive Coupler and Roller Guide Noise
The drive coupler and roller guide are two additional components that can create a loud humming noise. The best way to prevent this from happening is by applying some grease or oil on these parts whenever necessary so they have less friction when rotating inside the device. Another solution for reducing their sounds would be placing soft material around those parts of the appliance since it will absorb vibrations.
Cooling Fan Noise
A cooling fan is another component of a typical microwave that makes noise. It filters the air from outside when cooking, and its main function is to cool down your oven after use in order to prevent it from overheating or short-circuiting while not in use. The noise can be louder if there are some problems with a cooling fan.
High Voltage Diode Noise
The high voltage diode is a part of your microwave that emits microwaves and cooks food. If the device starts emitting strange sounds when in use, you might want to check its components for any damage or malfunctions. Another reason why this component may not work properly is that it overheated during cooking due to clogs within the oven cavity since such a problem will reduce airflow inside the appliance.
What is the First Thing You Need to Do Before Soundproofing a Microwave?
The first thing you need to do before soundproofing a microwave is by plugging it out and checking its noise level when in use. If the device makes loud noises, then there is an issue with either of these components: magnetron, cooling fan, or high voltage diode. In order to find where the problem lies from within your appliance, you will have to open it carefully until reaching one of those parts so check if they are working properly.
If all seems well after checking their functionality but still noticing strange sounds coming from your oven while using it, start looking for other possible reasons behind such annoying problems. You can also try different solutions for reducing interference that might not work right away so be patient and persistent! Let’s take a look at some workable ways to soundproof your microwave.
Hard Reset a Microwave
You can perform a hard reset on your microwave to resolve minor problems that are affecting its performance. Simply unplug the device from power, remove all components inside it and wipe them with a dry cloth before placing everything back in place. Plug the appliance back into an active outlet after waiting for around ten minutes so it has enough time to cool down completely, then try to use it again.
If you notice that the noise is still present, then there are some other problems with your microwave which will require professional help in order to be resolved. It might also mean that either of its components has overheated or reached a safety limit so replacing them would solve the problem once and for all!
Run the Silent Mode
Most microwaves come with a silent mode as an additional feature that might be useful when you want to cook without disturbing others. If the noise levels are high and unchangeable, then this option will lower both their pitch and volume level so it is easier for you to carry out your cooking tasks in peace and quiet!
Place Acoustic Foam Panels Where Your Microwave Fits
Another way to soundproof your microwave is to place acoustic foam panels around it to absorb some of the noise that travels inside and outside the device. Covering the walls and ceiling of your microwave with acoustic foam will help a great deal in order to reduce noise levels by around 70% or more.
This material is affordable, easy to install, and has many benefits when it comes down to sound insulation so make sure you utilize its advantages whenever possible. You will need more than two or three materials in order to make this solution efficient, so feel free to experiment with different combinations until you reach an optimal level. As such foam panels absorb high-frequency you need to place them around problematic areas where you suspect there might be issued with microwaves escaping from their intended space and see how well it works!
If even that does not help much, then buying an additional cover or plastic bag is another solution that should eliminate any sound produced by cooking food until finally reaching optimum performance once again.
Replace the Motor Drive Belt
Another possible reason why the noise levels are too high is because of a faulty drive belt which can be replaced if necessary so this solution might work wonderfully to resolve your problem. If you have problems with the motor drive belt you will start hearing unusual grinding noise.
You will have to open up your microwave for accessing its inner parts, then check how well the belt fits around them before you remove it completely. Afterward, clean all components with distilled water and let them dry out fully before replacing the motor drive belt by aligning it correctly around those moving parts that need energy in order to spin at an optimal rate without overheating or producing extra noises along the way.
Replace or Repair the Magnetron Tube
If you find that even after replacing the belt or your microwave is still giving problems, then it might be time to repair or replace the magnetron tube. In general, the magnetron produces a humming sound while working. But if you start hearing buzzing noise or humming sound becomes louder you may have problems with the magnetron.
In this case, you may need to check this part of your microwave and see what happened. You need to open up your device having removed the case and unscrew the magnetron. Check it for damages and clean every part carefully before placing them back in their original place and making sure they are perfectly aligned for maximum performance at all times.
If you do not see any problems you can plug in the device again and see if there’s any improvement with regards to sound levels you will need to replace the magnetron with a new one.
Clean or Replace the Drive Coupler
When the drive coupler is dirty or has problems, you will start hearing buzzing noise as well. You can clean it by removing all debris and replace it if necessary.
If you want to try the cleaning method first make sure that there’s no power going through the microwave before doing anything else! Then use a brush for sweeping away any dirt or dust particles present inside this component in order to check how much of an improvement this solution brings along with itself. If not even after brushing does not help too much then replacing this part might be your best option at hand so see what works better for you and your device’s particular needs accordingly.
Repair the Cooling Fan
When the cooling fan is not working as it should, then you might start hearing unusual noise coming from your microwave. This solution can be easily checked and repaired if necessary.
You will need a screwdriver for opening up your device and removing all parts attached to its shell after which inspecting them carefully before deciding what steps must come next. If everything looks fine with no damages or malfunctions found inside then you can clean the cooling fan from dust. If it does not help and your cooling fan continues working as a helicopter then replacing this part is the best possible option.
Replace the High Voltage Diode
If your microwave is still producing an unusual humming or buzzing sound instead of cooking food, then the high voltage diode might be faulty too. It can easily be replaced if necessary so this solution should work wonderfully for you and all of its particular needs accordingly.
You will need to open up your device in order to access its interior which must seem like a messy place at first glance but don’t worry about that because we are not going to take things any further than just checking what’s wrong and seeing how much of an improvement changing this particular part brings along.
In case replacing doesn’t bring results as well, then using new replacement parts should help tremendously so if possible replace both diodes since they commonly cause such issues.
Buy a Quiet Microwave
If you are not too keen about opening up your device or replacing any of its components, then this method is the best available option at hand so see how it works for you and all needs accordingly.
Buying a new microwave might be more expensive but if the soundproofing methods mentioned above do not help much to decrease noise levels inside your kitchen then purchasing a quiet one will definitely make life easier in that respect.
I hope you found these tips helpful and you will achieve a positive result with your microwave soundproofing.
