More Even Cooking & Better Defrosting

Try defrosting in an ordinary microwave and you'll get alternating blasts of full power followed by periods of no power until the timer goes off. LG Smart Inverter replaces this all-or-nothing approach with precise, variable power that provides more even cooking and better defrosting. Whether you're thawing a pound of meat or reheating last night's dinner, your food is heated more evenly, avoiding cold centers and overcooked edges.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Poor customer service

Microwave 1590S 12/1/2024

This microwave was a replacement for another LG that stop working. They sent the replacement promptly but then the door would not open on the replacement . It was taking so long I had to buy another microwave. They were supposed to refund me for the microwave. I still havent received a refund. This complaint was started on September 26th. Every time I call they say it I should hear from them in 2 days or its in RA dept one excuse after another. I feel this issue should have been taken care of by now. We have all LG appliances but I would never buy online directly from LG.

Did a Good Job But Would Randomly Trip Circuit

evelyn22 11/28/2024

The first oven we picked up at Best Buy was roaringly loud. We plugged it into our 20 amp microwave-dedicated circuit and it kept stopping and tripping the circuit breaker after 3-8 seconds. Thought it could be a lack of clearance so moved it to the kitchen island. Same tripping. After 7 days we returned it no questions asked to Best Buy. We tried this model again. This time it was nice and quiet and seemed to function as expected. This second machine defrosted very well and had superior cooking power. However it inexplicably suddenly tripped for either no reason or very little provocation. For example it stopped when someone waved a dishtowel in front of the rear fan vent. We are very tired of resetting our tripped circuit breakers every 4th - 5th time we use the machine so we are returning it.

Not loving this new neochef version

Sheri38 11/20/2024

We bought this microwave to replace the old LG 1.5 cf countertop microwave we had for 10 years and it finally died. It was awesome and we loved it. It was quiet and cooked the food perfectly and was easy to open and close and fit in our space. The new neochef is so loud Like an airplane getting ready for takeoff. If I put my hand on the door it gets a bit quieter. The new 5 point tray wheel is horrible. There are 3 wheels and 3 square pieces that drag along and the plate sits up too high. Also there is SOOO much condensation after cooking it is awful Is there any fix for this?? On the older version there was a :30 add time or reduce time which I liked a lot. Its gone. The clock does not keep time. I set it and it falls behind in a day. Also the almost all black door is constantly smudged with fingerprints. Why fix something if it is working???? This machine is like a relic from the 1980s. Total garbage. If the door is not supposed to be loose I would like a different machine or an explanation for why it is so loud please

High quality performance that fits a smaller place

Mythred 10/3/2024

Attractive fits perfectly in designed space works reliably and quietly. Lots of cooking options. I use the 30 second instant button often which can be increased easily in 30 second increments. Love the gentle ding when time is finished. Purchased through online LG website with help from chat representative who answered all my questions and found a microwave that met my exact requirements. Packaging and delivery was excellent.

I have been using this microwave for almost a month. For the most part it is working just fine. There is a kind of rattle when the turn table is moving. It may only be a loose fit. It is just an annoying sound.

Good microwave

Stellasmomma 9/16/2024

So far so good. We have had it about a month and it has worked out just fine. No kids in our house so we took a screwdriver to the side and disabled the child lock. I can say that even with the lock in place it opens nicely.

Circuit overload without reasons

pkpgh 9/10/2024

I concur with Nana146 on the circuit overload. The spec has 10.4 Amp power. We require to have arc flash breaker so we put in 20 Amp arc flash breaker for the microwave. It overloads the circuit FIVE times in two runs in one day. On average it overloads the circuit once a week. It will be in the basement soon enough. This is the second one we trade in. The first identical unit had the burnt smell when operated and louder than normal noise.

A huge upgrade for us

Simon2 6/24/2024

Our current home has a fancy microwave nook above the counter. When we bought the house the previous owners left their small old microwave. It was fine but small and heated unevenly. Ive been looking for a replacement since day 1 but its hard to find something which would fit. This microwave fits very nicely since it is very short compared to its width. I can now heat my two plates of cat food without them overlapping and spilling which by itself is priceless. I like the clean and bright LEDs so I can actually see what the food is doing and most importantly this microwave works very quickly and evenly for everything Ive tried. The one complaint is the sensor cooking basically doesnt work. Im disappointed in this because I used heard that microwaves with a humidity sensor do work and LG knows their tech well enough that I had high hopes but pizza mode just cremated my slice. Maybe the other modes will do better.

Poor quality control possible EMI shielding issue

mrock 6/19/2024

I wanted to love this microwave because I really like the design. However I ordered one unit that I immediately returned do to a rattling noise when on. I wanted to give it another chance and ordered a second. The second unit had less of a rattling noise but the magnetron noise was very unpleasant compared to other microwaves Ive used. Additionally the 0 button on our first unit was not very responsive to inputs. The second unit was maybe a bit better but still an issue. It is very frustrating because that is the most used button on most microwaves. Finally we have severe issues with EMI interference with this unit. When on our baby monitor does not work and it interferes with our house WiFi connection. That may just be an issue with our set up but we have not had the same issue with other microwaves.

Died after ~18 Months

RunningSmart 5/27/2024

After approximately 18 months this unit completely failed. While I generally like LG products this one has been a huge disappointment. The warranty expired after just one year. I hope LG will focus on creating higher-quality products that last beyond the warranty period.
