THE KITCHEN — When most of us hear the word "appliance," we probably think of large household machines that require at least two people to carry. You know, dishwashers, dryers and washing machines.

But the mighty microwave is also an appliance. And given its smaller size and simpler design, we don't tend to take care of it as well. With just a little manufacturer-suggested maintenance and awareness, you can help your microwave have a not-so-micro lifespan.

5 tips to get started

  1. Always cover food: This sounds obvious, but we're all guilty of throwing uncovered food in the microwave from time to time. Problem is, food splatters continue to absorb energy and cook after the mess is made. The result is lower efficiency and the potential for damage to your microwave.
  2. Clean the interior: Even in the best of times, messes can still occur in your microwave. Wipe out the inside on a regular basis to remove any foods and liquids left behind. And, every few months, consider cleaning it with a mild detergent. This will improve your microwave's performance and help guard against corrosion.
  3. Keep metal objects away: Everyone reading this article already knows that metal and microwaves don't mix. But do your kids know that? Even seemingly innocent things like aluminum can cause issues, as they reflect microwaves and can damage your appliance. So, make sure everyone in your home understands the risk.
  4. Never run it empty: It's not only what goes in your microwave to worry about. Running it when it's empty means there's nothing inside to absorb the microwaves, so they're instead absorbed by your appliance's components, which can cause damage.
  5. Take care of the door: The door to your microwave helps keep radiation inside the appliance so that food cooks evenly and your home stays safe. Never slam your microwave door, as this can damage the latch. You should also keep an eye out for any damage or cracks that could compromise the door.

A few brands to try

From tiny counter units to larger multifunction units, microwaves come in all shapes and sizes. The following are three great options I would suggest:

LG 1.3 cu. ft. Smart Low Profile Over-the-Range Microwave Oven with Sensor Cook

This new microwave from LG is one of the most low-profile models on the market, yet, it still has 1000 watts of cooking power and a 1.3-cubic-foot capacity. And when mounted flush with your cabinets, the door has a unique design that opens smoothly.

From a tech standpoint, there are lots of great features here. For example, you can sync the microwave with compatible appliances in LG's app and then make it so that the overhead vent and light automatically turn on when you're using the range/cooktop below. And there's a "Scan-to-Cook" technology that lets you scan barcodes from ready-made meals with LG's app and it will automatically dial up the ideal power level and cook time for you.

According to the manufacturer specifications, the microwave has 10 different power levels and uses sensors to detect humidity and adjust accordingly for the best results. And its print-proof finish means your kids won't leave fingerprints and smudges all over it (at least, not as much as usual).

Sharp 1.9 cu. ft. Smart Over-the-Range-Microwave Oven

This over-the-range unit has 1100 watts of power, 1.9 cu. ft. capacity and a 13.6-inch turntable, making it ideal for large families. It also has a four-speed ventilation system that does an incredible job of getting rid of cooking steam and smells from the range below.

One thing you'll notice right away is this microwave is super quiet. You almost can't tell it's running, which means you don't have to turn your TV up or talk louder on the phone while it's in use. And speaking of sounds, the microwave also connects with Alexa. There are 65 voice commands to use, which becomes very convenient when your hands are messy and you don't want to touch the buttons.

Additional features, according to manufacturer specifications, include a removable grill rack for double-decker cooking and sensors that can automatically adjust cooking times, so you don't waste energy or create unnecessary splatters.

KitchenAid Multifunction Over-the-Range Microwave Oven with Flush Built-In Design

KitchenAid has added nearly everything but the kitchen sink to this multifunction unit. In addition to the standard microwave/ventilation hood, you get an air fryer, toaster oven, convection oven, food dehydrator and bread proofer. The appliance is equipped with triple heating elements that cook at temperatures up to 450 degrees Fahrenheit — which this manufacturer ensures is perfect for baking, roasting, broiling and toasting.

Even with all the cool technology in this microwave, it's still got a flush design that sits further back in your cabinets than many other models. The one compromise is the interior is on the small side, with just 1.1-cubic-foot capacity. While that's undeniably cozy, it's still enough room for most mixing bowls and dishes. And it comes with a removable rack, so you can often double up the amount of food you're cooking.

One of the most unique features of this microwave is the integrated meat thermometer, which monitors your food and then automatically turns the appliance off when it reaches the proper temperature. And since this is a smart appliance, you can preheat, monitor and control it through KitchenAid's app. You can also use voice commands via Google Assistant or an Alexa-enabled device.
