LG LMV2031ST Microwave Oven Review

LG LMV2031ST Microwave Oven Review

Over the decades, kitchen appliances have come a long way, incorporating numerous features to provide optimal results and save time in our busy lives. Many of the vital appliances we see in a modern kitchen include not one, but many other functions that cut short the need for another product, just like an Over-the-Range microwave.

An Over-the-Range or OTR microwave is a combination of a microwave oven and a range hood. In some cases where it incorporates the convection feature as well, it also becomes your secondary oven. It’s basically a 2-in-1 device that eliminates the need for a dedicated range hood in our kitchens. However, it should be noted that any OTR microwave compares poorly to the peak capacity of a powerful under-cabinet range hood. Like most other over stove microwaves, this one satisfies venting requirements of small to moderate sized kitchens. That’s why it has become a priority in smaller kitchens as it saves a great amount of space which would otherwise be totally occupied by a range hood.

LG LMV2031ST is one of the best OTR microwaves available in the market, which is a suitable option for most of the kitchens. Customers across the world are pleased with its convenience and efficiency. So, in this LG LMV2031ST microwave review, I will be informing you of each characteristic of this model from its design, size, wattage, features to controls, venting system, price, and warranty an overview of its performance and reliability. As a takeaway, the microwave is fairly reliable for the price and takes a decent spot in our top recommendations for the best over-the-range microwaves across all budget segments.

Over-the-Range microwaves are created to save more valuable countertop surface area. As OTR microwaves are to be installed above the range or oven, the size of the model has to match with the existing kitchen oven in order to provide excellent ventilation. The LG LMV2031ST features 30 inches, which is considered the standard size for an OTR microwave. This model comes with the exterior dimensions of 29.94 × 15.87 × 16.44 inches and the interior dimensions of 21 3/4″ × 10 5/8” × 14 5/8” which is perfect for most of the kitchen ovens, be it smaller or larger.

The capacity of LG LMV2031ST is 2.0 cu. ft. which is justifiably large for the actual size of this microwave. This microwave features turntable operation, which is DDS type with a great 14.2” diameter to enhance the cooking capacity.

3. Wattage

Another important aspect that goes overlooked by customers is the power rating of a microwave. The working of a microwave depends on its hardware known as a magnetron tube. The ones that produce less than 700 watts, can’t spread the heat evenly, so the cooking time gets increased whereas a 1000 watts microwave ensures fast and even cooking every time. The LG LMV2031ST has a wattage of 1000 watts, which is known to be the threshold wattage count for a good microwave. That’s why it prepares your favorite dishes efficiently.

Different types of foods require different power levels. When you see a delicious recipe wanting 800 watts with 5 minutes to cook, you have to increase the cooking time in your microwave if that is less than 800 watts. But, this LG LMV2031ST features 1000 watts with 10 power levels, which can turn into the apt wattage the particular food needs without extending the cooking time.

4. Control

Digital controls are more convenient than push-button controls on any kitchen appliance. When you’re working hard in your kitchen, you don’t want to give directions to a machine. That’s why LG LMV2031ST features Smoothtouch Glass Digital Control with a Green 4 Digit LED Display placed on the left of the microwave. The touchpad comes with one-touch settings to save you more time.

Apart from the basic features to operate, the panel also includes some of the important shortcuts and cooking modes like auto defrost, quick defrost, and only having to touch one button for some foods like Pizza and Popcorn. There is also a frozen entry option given on the panel.

5. Venting System

Venting System Review in LG LMV2031ST Over the Range Microwave

Over-the-range microwaves are the only ones among other types that come with a fully functional venting apparatus incorporated in its design. The assembly consists of charcoal/grease filters, exhaust fans and often a customizable outlet. An OTR microwave reduces the dirty smoke and odors, which are produced by cooking in the kitchen. If you want efficient results just like a dedicated range hood, you have to choose an OTR microwave with good fan speed. Microwaves that have venting airflow of 300 CFM or lower than that can’t eliminate all the polluted air from the kitchen. But LG LMV2031ST features 400 CFM, which gives you relief from the smoke and from airborne particles and grease and oil from the kitchen. It also offers 3 fan speed settings – Turbo, Hi and Low, to speed your kitchen needs. Compared to the ventilation of a downdraft cooktop, the microwave performs better at venting out steam and cooking odor.

This model offers Charcoal Filtration, which captures all the grease and oil and filters the dirty air. The venting grills are hidden, and it features a QuietPower Ventilation System so you can’t hear any noise when it’s on duty. The venting performance is in lines with any high-end downdraft cooktop
