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.

Great overall experience

Briandon 11/23/2023

We purchased our microwave 1 year ago. It has worked great since day one. However 9 months in the digits showing time would flicker constantly in the background So it was noticeable but faint. I called for warranty service and they were very quick and helpful They tried trouble shooting with me but in th end needed to schedule a service call. He cam and replaced the panel within 15 minutes at no charge and now all is good. I like the product the company and its service organization.

Not working

DAO1 11/19/2023

Before the warranty was up it had to be fixed. Now it is a little over 2 years old and it doesnt work at all. The first thing that was repaired under warranty is happening again and it doesnt heat anything. I have been waiting for weeks to get LG to send a repairman in case it is the magnetron. I am extremely disappointed.

Poorly Made

Scott Murray 11/12/2023

The long piece above the door is attached to the microwave by cheap plastic. Heat from the stove ruins the connection which makes the long piece come off. After paying for a replacement part because the warranty had just ended the replacement part also broke off. Im using makeshift parts from local hardware store to keep it together.

Made cheaply

Scott Murray 11/12/2023

The microwave functions good. The issue with this product is the piece directly above the door connects to the microwave using cheaply made plastic connectors that are screwed in. Those pieces break due to heat and because they are plastic. I replaced the piece as it was just one year originally buying the microwave and the warranty didnt apply. The replacement piece also broke within a month. I would not purchase this particular microwave this is your warning.

Mark Stri 9/30/2023

I bought this microwave approximately 1 1/2 years ago and the LED Display has failed twice. 1st it was fixed under the warranty and now LG refuses to replace w/o charging me for parts and labor. The microwave itself works fine its just the display continues to fail.

DJ55 7/25/2023

We had a LG microwave before and it went out before 2 years. We are trying another one and it seems like this is an updated version of our last one. It is an under the cabinet model and the inside seems lower then the other one which makes it easier to reach inside. Also the ending tone is much quieter and the lights seem brighter. Weve only had it for 2 days so havent used many features but these stood out. Great Job LG

Nate52 7/23/2023

I choose this microwave for the name. I thought spending a bit more and getting a name brand Ive heard of would be a good idea. I thought it would last me a while. Where are the days of microwaves lasting 5 or 10 years? I called LG and no one was of any help?

Steven Puri 6/20/2023

Mocrowaves OK but the panel is hard to read

Rich Durkee 5/17/2023

If you dont have a light on in the kitchen you cant see the panel. It is not back-lit. Also the panel is stiff and so it is difficult to set a time of use any other function without really pressing hard.

Good microwave

Noifsamdsorbutts 3/15/2023

The microwave is attractive and well built with easy cleaning. We use this several times a day so it gets a workout. The only problem we had was it just stopped working. After a call to LG a tech appointment was made quickly and easily. The tech we had was here in just 2days and right on time. He came in and had it figured out in just a few minutes went out to his van came back with the part and was back up and running again. Very professional and neat.

Easy to use and clean

Jetball 2/20/2023

I like the printless stainless steel finish which matches our frig and dishwasher. The user panel is not on the door which I prefer. It is easy to operate if you have ever used a microwave before. The inside is easy to clean but is brown not white. We prefer white but brown is ok. The damper assy is rather flimsy and the installer had a difficult time installing it. I am still not sure the damper is opening like it should.. other than the damper it is working great.

Hard to see keypad. No light dark scheme.

Copernicushell 1/12/2023

I hate this microwave. Does it perform? Yes Is it accessible for dark rooms or for sight impaired users? No The keypad screen in the product image is bright and crisp. This is absolutely not the case. If you have a dark kitchen are installing in an area with adjacent windows that cause reflection have sight impairments relative to age or disability this keypad will be an issue. Our only solution is to attempt to find a stick-on mini down light.

Serious flaws in design

cre612 1/2/2023

Thirteen years ago when we renovated our kitchen we happily installed all new LG appliances. I wont get into the problems weve had with the refrigerator and oven at this place and time but we were always extremely happy with the over-the-range microwave. Recently it just died without any warning on Thanksgiving eve but at least it had a good run. We replaced it with the LG LMV1831SS. When we saw it on display in Best Buy there was no way to plug it in. So we were very surprised when we installed it at home and tried to use it for the first time. I do not have super vision like Superman and so I cannot see what any of the buttons are for unless the kitchen is fully lit up. The clock on the top of the display is lit up like the Rockefeller Center Christmas tree but nothing else is Not only that but the buttons are not very sensitive and I find myself pushing hard on them to make them work. Its aggravating and frustrating. If you see the photo of the microwave online the buttons are nice and clear almost like they are backlit. That is not the case Very misleading They are totally dark. I swear that theres a film over the buttons to keep the area looking new and I keep trying to pry up the corner of the film so I can see the buttons better but thats not the case at all. Its just that poorly designed. My old microwave was so much better The second thing Im unhappy about is not as important but very disappointing nonetheless. When I close the door of the microwave the sound is very tinny and it gives the impression of a cheap appliance. I know microwaves are hollow but the door of my last LG microwave gave a nice solid thud when it closed. I havent yet tried using the included metal tray for microwaving multiple items at once but Im hoping it turns out to be a useful feature. I also havent yet used the vent and probably wont. The only problem I had with my last LG microwave was that the vent sent all the greasy air straight up to the upper cabinets and ceiling without removing much grease. I would even get straight lines of grease on the ceiling that matched the shape of the vents. But I dont suppose much can be done about that when there is no way to install an outdoor vent. I hate that LG cheapened the new designs and hope they return to better quality.

Cant read control panel :-

Angela Forker 12/7/2022

We just bought an entire set of LG appliances. I love all of them sooo much...BUT I am extremely disappointed with this microwave The LG photos advertising it show bright legible numbers and words but in person they are hardly legible Even in bright light I cannot read these words I ended up overcooking something. I tried to stop the cooking but couldnt find the button because I couldnt see the words So this IS a problem Its not an issue at all with the stove. I see those numbers and words completely clearly but this microwave has GREY words on black See photo to see both displays. When I purchased this I was sure the words would be lit up but NOTHING I asked for support and all they said was Sorry this is the design. Feeling disappointed and very frustrated.

Dark Control Panel

Stace66 11/21/2022

Bought almost a month ago very disappointed with rattle/wobbling sound when it runs but even worse is the extremely dark Control Panel Cannot see without other kitchen lights on even during daytime. Thought I must be missing some light for the panel but in dealing with LG customer service for just short of an hour I got neither issue resolved. Would not recommend.

Heats up food well

HouseHubby85 11/17/2022

Overall its a pretty good microwave. Seems to heat up food quickly and evenly. It looks good and matches the rest of our LG appliances well. Similar to the stove the buttons could be a bit easier to push. I also would expect the lights to be brighter both in the microwave and below. I would expect them to match the bright LED lights of the fridge and dishwasher. One thing I cannot stand about this microwave is how loud the beeping is on it. If I am heating something up I am typically standing in the kitchen I do not need to hear this aggressive tone from a mile away. I thought perhaps it would have a tone similar to the washer and dryer. I look forward to hearing those theyre happy and much more pleasant.

Review on my LG Microwave

Barbara Burch review 11/13/2022

Purchased in October from Home Depot. They didnt have a model on the floor for me to look at. I went online to look at your marketing information and photos. The ones I saw all had the letters on the display visible against the black background Plus my brother has one and his is white letters. Once mine was installed I realized the entire display except for the time was all dark. I need to keep a flashlight by my microwave so I can see what commands I need to push ie Cook Time Defrost Melt etc I called customer service and was told this is the way it was designed. Cant believe this. Wrote a letter to your office havent heard back. Completed a notification online. Received a message saying yall are going to look into this But no one seems to be interested in correcting my unit. Im very disappointed in the feedback Ive received Guess you expect me to live with this inferior product the rest of its life OR place it on the curb and purchase another brand that I can see

Alza 11/11/2022

The buttons on the control panel are hard to push. The display is not backlit it is very difficult to read the buttons. The photo of the unit had to be photoshopped to make the buttons stand out like that. And an Energy Saver button that only turns off the timer display? O please.
