Microwave ovens were life-altering from the moment they began humming and heating homes in the 1970s. As a tool for cooking, microwaves are very helpful. They are small, nimble, and remarkably versatile machines, but how do they operate? Will use the microwave harm you in any way? In this article, let’s seek answers to each of these queries. So let’s get started.

What is Microwave Oven?

How Does A Microwave Oven Work - Complete Guide to Use It in 2023

A microwave oven is a household appliance that has revolutionized modern home kitchens. It is designed to cook food quickly by using special electromagnetic radiation that heats objects from within. It is primarily used to quickly heat food and is most practical for lengthy tasks like melting butter or heating water. Microwaves cook food from the inside instead of the outside, unlike conventional ovens. Although it was first employed in commercial kitchens, today homes and workplaces are where it is most frequently seen.

When you hit the start button “it usually takes about 2 seconds to heat up a filament inside the magnetron tube,” says Following that, the food compartment is blasted with microwaves, says Schiffmann.

Water, fat, and sugar are readily absorbed by the microwave frequency that is most frequently used, 2.45 gigahertz. Says Bloomfield: “The waves are at the right frequency to penetrate deep into food and they deliver cooking power primarily to the food’s water content. Solids devoid of water hardly absorb microwaves.” That’s why microwave-safe containers don’t get as hot as the food inside them.

By twisting water molecules back and forth, microwaves heat food, such as a cup of coffee or a slice of lasagna. The ends of water molecules are each positively and negatively charged. Bloomfield claims that one water molecule resembles the head of Mickey Mouse. Consider Mickey’s face to be the negatively charged oxygen atom and his ears to be the two smaller positively charged hydrogen atoms.

The negatively charged end of the water molecule points away from the electric field of the microwave, while the positively charged end attempts to align itself with it. But because the field reverses 2.5 billion times a second, Mickey’s ears and face are being twisted back and forth rapidly.

The molecules rub against one another as they oscillate back and forth. Friction is produced as a result, and heat is generated.

According to Schiffmann, a microwave cooks food much more quickly than a conventional oven because it simultaneously microwave heats the inside and outside of the food. In a typical oven or frying pan, the food’s surface is heated first and then the heat gradually moves inside. Foods do not brown or become crispy as they would when cooked in a conventional oven because the air inside a microwave oven is room temperature.

What is Convection Microwave Oven

How Does A Microwave Oven Work - Complete Guide to Use It in 2023

A convection microwave combines some of the features of two kitchen appliances – a microwave and a convection oven, allowing you to bake and roast foods in addition to heating them. Thanks to their versatility and small size, convection microwaves can be a good choice for small kitchens, apartments and RVs.

A convection microwave has at least two operating modes, the first of which is the conventional mode, which employs microwaves to heat or cook food. The second option is a convection mode, which turns your microwave into a convection oven. A convection oven uses a heating element and a fan to distribute heat throughout the appliance. Because of this, a convection microwave enables you to use cooking methods like baking, roasting, and broiling that aren’t possible with traditional microwaves. Convection microwaves let you alternate between both modes to cook foods faster.

When Was the Microwave Oven Invented

How Does A Microwave Oven Work - Complete Guide to Use It in 2023

Over 70 years ago, an engineer testing a military-grade magnetron discovered it had melted a snack he was carrying in his pocket. This discovery led to the accidental invention of the microwave. Accidentally, the microwave oven was created. Or not, since some people were already aware of what microwaves were capable of. Only one man asked himself how these microwaves could be used in a peaceful manner.

A few interesting facts about microwaves:

  • By 1997, more than 90% of American households owned a microwave oven, up from about 25% in 1986.
  • Due to its dipole molecules, microwave heating is most effective when applied to water and less effective when applied to fats and sugars.
  • Microwave ovens do not cook food “from the inside out”. It’s a widespread misunderstanding.
  • Any metal or conductive object placed in the microwave oven will act as an antenna and, if it has sharp edges, could result in an electric arc or even a fire.
  • A metal box that contains the food and functions like Faraday’s cage stops microwaves from escaping the oven.

How Long Do Microwaves Last

Even with heavy use and poor maintenance, the typical microwave oven only lasts about seven years under normal use. As a large family becomes more dependent on the appliance to heat up snacks and leftovers or to defrost meals, they may find that they need to replace it every four to five years. If the incorrect items are put inside, they may result in irreparable damage or a risk of fire, which can reduce this lifespan even further.

How to Clean Microwave Oven

Here are some of the things you need to know when it comes to cleaning your device:

Wet Paper Towel Method

A lot of wet paper towels would be more than enough to clean your microwave if it doesn’t appear that a nuclear explosion occurred inside of it. You only need to put the wet paper towels inside the microwave and run it on high for about 5 minutes. Using this trick will help you remove unwanted dirt and contaminants from your microwave by creating steam. It also functions as a starting point for more difficult problems, like stuck food.

Using Dish Soap

This method functions very similarly to the wet paper towel method. Water and dish soap mixed in equal parts should be placed in a non-metallic bowl that can be used in a microwave. Let it run at a high temperature for only one minute, or until it steams. After removing the bowl, wipe the microwave’s interior with a sponge. While you’re at it, don’t forget to clean the microwave door.

The Power of Baking Soda

In addition to other uses, baking soda is the go-to cleaner for stuck food in your microwave. You can easily remove any hardened food from your microwave by making a paste out of baking soda and water and applying it there. Simply wipe it off with a wet sponge or towel after letting it sit for at least five minutes. You may repeat the process until you can completely and easily remove the unwanted burnt food inside.

Vinegar and Water Solution

Similar to using dish soap, this solution can be used in the same way. One cup of water and one cup of vinegar should be combined equally in a bowl that can go in the microwave.

Put it in the microwave and let it steam for a long time. Before reusing the appliance, wipe it dry to ensure that there are no vinegar residues inside the microwave.

A natural cleaning solution that has stood the test of time and is incredibly adaptable is vinegar water. A match made in heaven for an extra dirty microwave.

How to Repair Microwave Oven Not Heating

Possible reasons why your microwave isn’t heating up are listed below, along with possible fixes. If these steps don’t work, or if you are unsure of how to proceed, contact a qualified service technician.

Step 1: Check the Microwave’s Power Supply

Verify that the power supply for the microwave is connected to a grounded, working outlet. If you are unsure if the outlet being used is working or not, try plugging in a lamp or other small household item to see if it turns on. If the outlet seems to be working properly, check to see if your home’s circuit breaker or fuse has blown.

Step 2: Ensure the Door is Closing Properly

The door of a microwave must be properly closed before it can begin to heat as a safety measure. Check to make sure the microwave door is firmly shut before attempting to operate. If your microwave is brand-new, make sure to take out the shipping spacer and any remaining packaging that might be preventing the latch from closing all the way.

Step 3: Check the Microwave’s Controls

Make sure the controls on your microwave are set to the appropriate temperature for the object you are trying to heat. Your food is probably coming out cold because the current settings aren’t producing enough heat for your dish, in which case you should adjust the power level.

Step 4: Check for Error Or Display Codes

If your microwave encounters an error or is set to a specific mode, the unit will not heat and a code will appear on the display. It is necessary to disable Control Lock and Demo Mode in order to allow the appliance to heat up again.

Air Fryer Vs Microwave

How Does A Microwave Oven Work - Complete Guide to Use It in 2023

It would be difficult for me to choose a microwave or air fryer if you asked me to choose one over the other. Microwave ovens and air fryers both excel at their respective processes. It is wonderful to have both gadgets in my kitchen, which motivates me to cook every day.

The microwave is the winner if you want to make a purchase or choose a cooking method solely on which is less expensive to operate. But because they can be used for different things, it’s typical to have both a microwave and an air fryer in the kitchen. (Read More: 20+ Instant Pot Air Fryer Recipes 2023 – Tasty & Delicious)

Food cooks and reheats effectively in a microwave. Foods cooked in an air fryer have a crisp, fried texture that a microwave simply cannot match. A faster and healthier option for cooking is an air fryer.

In the end, it depends on what you like to cook and which appliance is best for that, but using both is certainly acceptable.


Due to the fact that a magnetron electron tube inside the oven creates microwaves, microwaves are masters at quickly delivering hot food. Many more recent microwaves go beyond what a microwave typically does. To stimulate the food’s molecules and generate heat, they use electromagnetic energy. Some microwaves also have settings that are akin to those found in conventional ovens, such as convection cooking, broiler-like heat, and low heat to keep food warm.


How Do Microwave Ovens Work in Physics?

By bouncing electrons around in a vacuum-filled cavity that is exposed to a strong magnetic field, the magnetron produces microwave radiation. This magnetic field forces these electrons to circle around inside the cavity, absorbing energy. This energy is eventually released as a microwave.

What is the Point of a Microwave Oven?

A microwave oven is a very adaptable kitchen tool with a wide range of applications. Food can be heated up and cooked in a microwave oven, as well as used to dehydrate honey and roast garlic. They can also be used to clean kitchen utensils and make citrus fruits more juicy.

Is Microwave Radiation Harmful to Humans?

Non-ionizing radiation includes radio waves, visible light, and microwaves. UV light is the only non-ionizing radiation that can cause cancer. In conclusion, microwaves are safe to use and do not harm human health in any way, including the development of cancer.

What Makes a Microwave Heat Up?

By creating intermolecular friction between the food’s molecules, microwave ovens cook food. The microwaves cause water molecules to vibrate; the increased friction between the molecules results in heat.
