LG LMC0975ST Microwave Review

Tested using Methodology v1.0
Reviewed Jul 10, 2024 at 10:13 am

The LG LMC0975ST is a small, budget-friendly inverter microwave. Most of its buttons are hidden when the door is closed, giving it a sleek look. Instead of a handle or button, you open it by pulling on the door. It has basic features like a popcorn button and defrost function, but you can't mute the controls, and it doesn't have a steam sensor.

Our Verdict

10 Power

Although it's a 1000-watt microwave, the LG LMC0975ST is efficient and can heat food faster at maximum power than some bigger 1000-watt models like the LG LMV1764ST.

  • Heats food quickly.
  • Sleek design.
  • Suitable for small kitchens.
  • No steam sensor.
  • No mute function.

Differences Between Sizes And Variants

The LG LMC0975ST comes in one stainless steel variant. You can see the label for the unit we tested here and here.

If you encounter another variant, let us know in the comments, and we'll update our review.

Compared To Other Microwaves

The LG LMC0975ST is a small inverter microwave. While it has lots of automatic programs for cooking, reheating, and defrosting, it doesn't have a steam sensor, and you can't mute the controls. It stands out for its design, which hides most buttons when the door is closed. If you want a small microwave with a mute option, you might like the Insignia NS-MW09SS8 or the Toshiba EM925A5A-BS instead. The Toshiba EM131A5C-BS is an option with a steam sensor, although it's not quite as small.

It's a small microwave. A bump on the roof of the cooking chamber results in less usable height inside. The light inside makes it very easy to see into the cooking chamber when it's running.

Controls And Functions
Door Release
Recessed Handle
Cooking Sensor
Popcorn Button
Defrost Button
Add Time Button
Kitchen Timer
Mute Sounds Button
Lock Controls Button

Most buttons are only visible and accessible when the microwave door is open, which gives it a modern look but makes the controls a bit less accessible, which you might find annoying. That said, you can start, stop, and add time to a cooking cycle with touch-sensitive controls on the outside of the door. There are programs for reheating, cooking, and defrosting different foods. It doesn't use a sensor that detects steam, so all its programs are based on time or weight. You have to refer to the manual to know which program is which, and then repeatedly press the Auto Cook, Auto Reheat, or Defrost button to cycle through the options. There's a dedicated 'Popcorn' button too. Pressing 'Start' once will start a 30-second cook cycle immediately. Unfortunately, it beeps whenever you press a button and at the end of a cycle. You can't mute the controls.

There's no noticeable difference between microwaves for heating food in shallow containers. Evenness depends on factors like what you're heating, in what amount, and in what container. If you want to know more about microwave performance, you can read more about our investigations here.

Like with shallow dishes, microwaves all perform similarly when heating food in deeper containers. Heating evenness depends on what you're heating up and in what container. You can read more about our investigations into microwave performance here.
