1. What Microwave Ovens Do

Microwave ovens are now used for more than just heating food or boiling water by only home users. Chefs use them; they are located in convenience stores; gas stations; office break rooms; school and college dorms; and renters at apartments and condos. RVs, and semi-trucks use them with an inverter.

Baked goods, pastries, pizza, popcorn, entire meals, defrosting, and more are done today in a microwave. A regular oven takes about an hour to bake a potato when it bakes under 10-minutes in a microwave saving power costs.

A new and very best countertop microwave is compact and portable to take with you when leaving an apartment or college door room. When replacing an old microwave or one that has broken, you will appreciate the features so convenient in the new ones.

Many have locks to keep the little ones out, many levels of power, customized cooking menus on the control panel, programmable defrosting, warming up leftovers, a clock, and a timer setting.

The designs are as sleek as a Corvette car that are available in stainless steel, black, white, and retro fun colors to harmonize with your kitchen décor. They are large inside with a glass turntable and easy-to-open handles. Some models will turn off the beep tone if you don’t want to hear it using the buzzer mute button or the method listed in the User’s Manual.

The more wattage a microwave has, the more power for cooking in shorter times.

2. Features to Consider

The most import things to consider for your best buy functions are:

Size Outside and Capacity Inside

For less space, compact countertop microwaves might just be for you, or for a larger family, you might want an extra-large unit for over the range, that are not reviewed here.

One-Touch Buttons

Press a specific preprogrammed button that shows pizza, baked potatoes, popcorn, hotdogs, and others. Buttons are shown for reheating, defrosting, and more.

Menu buttons let you do multiple functions. For example, if you want to make a bowl of oatmeal, first add cold water to a bowl, put into the microwave and push 3 for 3-minutes to get it to boiling. After it shuts off, open the door and add the oats, and close the door. Push 7 for 7-minutes then push 4 for the power level, meaning 40% power, so that it doesn’t boil over and when it’s finished, the beep sound will tell you to open the door and take it out.

My microwave reviews below show #5 to be well adapted for seniors and those in wheelchairs with rotary knobs.

Power Level

Most of today’s microwaves have at least 10 levels of power from which to choose other than high, which is 100% power. These levels let you simmer, cook at a medium high rate and others. Read my microwave oven reviews here to find the best brand, wattage, cubic-foot sizes, and functions for your needs.

Microwave ovens are not Energy Star® rated since they use such little power.

If you want to make toast, microwaves will not do that. Get yourself a toaster oven for brown toast.

The microwaves reviewed here are not convection ovens.

FAQS for Microwave Ovens


What is the difference between a toaster oven and a microwave oven?


Browning—Toaster ovens can brown foods, microwave ovens cannot. With a toaster oven you’ll have a          function to broil similar to an oven broiler; with a toaster oven doing broiling is faster.

Countertop Accessibility—Both ovens can sit on the kitchen countertop, however, most microwaves are installed over the cooking stove. The microwave is much heavier than a toaster oven. Microwave ovens are bigger and require more headspace than do toaster ovens.

Energy—The microwave is a little more energy efficient than a toaster oven. Microwaves typically pull about 700- to 1300-Watts of power and a toaster oven pulls about 1200- to 1800-Watts of power.

Crispy Food—The toaster oven will crisp up food whereas a microwave cannot do this. The broiler in the toaster oven will create crisp bacon, meat, bread, potato chips and more without all the grease to do this when frying on the cook stove.

Reheating Bread—Microwaves will make the bread tough; toaster ovens will make bread and pastries soft.

Big Meals—Microwave ovens will make larger meals when you have its larger capacity oven. However, both the microwave and toaster oven can bake a whole chicken these days and a 13-inch pizza.

Heating—Both ovens are similar. However, it will be contingent on what food is being heated. Equally, the microwave might be faster heating some foods, but it can toughen them. The toaster oven distributes heat to some extent longer on meats yet provides more even cooking at a slower time for cooking it. Baked potatoes turn out about the same in both ovens.


What is an inverter microwave oven?


The first company that developed a microwave oven to use inverter technology was Panasonic®. A regular microwave oven uses a magnetron connected to its transformer for power. The transformer’s voltage is stepped up from its low-voltage that the wall outlet receptacle it’s plugged into provide.

The magnetron on the inverter microwave is powered from the inverter circuit. During operation of this oven, the circuit can control the amount of power to the magnetron that controls the power level of the inverter microwave oven when it is operating. The main advantage of the cooking process for this oven’s cooking is its variable method for controlling temperature when cooking.


What is a convection microwave oven?


It is the combination of a convection oven and a regular microwave oven.


What is a combination microwave oven?


A regular microwave oven is a cross with a full-size convection oven used for baking. It is combining both together as one oven.

The convection microwave ovens are incredible when merging the technology of both ovens. If you have the money and space to buy it with three distinctive modes being microwave, convection, and grill modes, you will love it.

In the microwave mode you do the same as with any microwave: reheat coffee, cook frozen vegetables, defrost, make popcorn, and more.

The convection mode is like using a regular oven for baking cakes, cookies, pizza, pastries, and pies.

The grill mode of the combination oven is the magic of this oven in that it will grill burgers, steak, chicken, and more.


How does a microwave oven work?


Don’t you first want to know what microwaves are? I do! They are in the atmosphere like the air we breathe. Microwaves are used for more than ovens! They are used for wireless communications: cell phones, Bluetooth, broadcasting systems, navigation, burglar alarms, garage door openers, police speed detectors, just to name a few.

Microwaves out in space are highly technical to discuss. Read Microwave Oven Radiation to learn more.

Electricity is turned into heat. Inside the oven’s metal box is a microwave generator known as a magnetron. When you start cooking, the magnetron takes the electricity from the home’s outlet converting it into high-powered 4.7-inch radio waves.

The magnetron sends these waves into the food area through a wave guide channel where the food is on a turntable spinning slowly around being evenly cooked by the microwave energy. The microwaves pass through the food and as they do, they vibrate the molecules fast. Heat is produced by vibrating molecules. Therefore, microwaves pass its energy to the molecules in the food, heating it up quickly.


When was the microwave oven invented?


The modern microwave oven, generally called ‘microwave’ was invented, and usually credited by American self-taught engineer Percy Spencer from Howland, Maine in 1945. He worked for Raytheon, a missile defense company, at that time after World War II and used radar technology during the war. The oven was then named the ‘Radarrange.’ It was sold first in 1946. Percy accidently discovered the heating effect of a high-power microwave beam when he noticed that microwaves from an active radar set that he was working on started to melt a chocolate bar he had in his pocket.

Home-use microwave ovens were created when Raytheon licensed its patents later on, and in 1955, Tappan introduced these microwave ovens that were expensive and too large for home users.

The first microwave oven with a turntable was sold by Sharp Corporation between 1964 and 1966.

In 1967, the Amana Corporation gave us the countertop microwave oven.

In the late 1970s, after Sharp launched low-cost microwaves for home use, they then extended into commercial kitchens globally. The ovens are also used in industrial procedures for heating.

Tips for Microwave Ovens

Microwave Oven Tips

  • Read your instruction manual to understand how your countertop microwave works.
  • It’s important to know the amount of time it takes to cook specific foods and your User’s Manual will tell you. Plus, you will learn by trial and error.
  • Different Watts and different brands for microwaves vary. A 700-Watt oven will not have the power of a 1200-Watt unit.
  • Don’t know the Watts of your oven? Check the door panel on the housing on the left side on inside bottom frame edge. If it’s printed on the back, write it down on your User’s Manual to have at hand.
  • Standing time is the time it takes for the food to rest. That’s the same as using a regular oven. It lets the food have time to blend the flavors improving the taste. Let the food rest inside the microwave for best results.
  • When your plastic bottle of honey has turned to sugar, remove the sugar crystals by putting the bottle in the microwave for 30-seconds to a minute. Do this again if all the crystals have not dissolved. Be sure to open the lid or remove it.
  • To clean your microwave, put a bowl of water inside and let it run for a few minutes then sit for the steam to do all the work. Remove the bowl and wipe clean. Glass turntables are best handwashed for not chipping in the dishwasher.
  • Never use scratchers, abrasives, or sharp knives in your microwave; it will damage the inside material its made of. Dishwashing detergent will work just fine.
  • Never ever put metal or stainless-steel cookware inside a microwave. It will cause sparks and ruin your oven.
  • It’s best to cover your food with a microwave plate cover for under $10, paper towel, or plastic wrap to avoid the mess to clean up in the first place. I know I love mine and it’s dishwasher safe on the top rack.

  • Do you want to pasteurize your garden soil without using the power of a regular oven to heat your kitchen for potting soil? To kill the diseases in soil and prevent problems with your plants, simply fill a paper bag (not plastic) with soil and cook in your microwave oven that uses less energy than the big oven. Be sure the soil is moist; if not, add drops of water. The minimum temperature is 140-degrees for a half-hour. Your instructions will tell you the power level for temperatures. Remove the soil, let it cool in the paper bag, then pot your seeds or plants. I’ve had success with this using my own garden soil or commercial soil in bags.
  • You will want to know the output wattage not the input wattage of your oven.
    • 1000-Watts or more—water boils in less than 2-minutes.
    • 800-Watts or more—water boils in 2-1/2-minutes.
    • 650-700-Watts—water boils in 3-minutes.
    • 300-500 Watts—water boils in 3- to 4-minutes
    • I have a 900-Watt microwave in a popular brand, and it takes 3-minutes to boil a cup or mug of water.
  • Before grabbing a hot cup or hot plate, touch it; you might need to use a pot holder.
