Keypad too dark

LG Microwave LMV1831SS 9/27/2022

Bought this 2 weeks ago unhappy with the microwave because the keypad is too dark. I have to turn on light even during the day to see the numbers. Microwave already attached to cabinet so hard to remove and return.

Great microwaveI would only change one thing.

TVon 9/23/2022

This is a great microwave and is very easy to use. All the features are nice to have including the rack inside. Buttons are very reactive and unlike previous microwave ovens I have owned it seems to heat evenly. Installation was even easy. The only thing I would change is the light as it is a little dimmer than I would like but overall I am very happy.

Good basic microwave

Gas Range Detailed Review 9/23/2022

We bought a whole suite of new LG kitchen appliances largely due to the buy more save more promotion. We originally picked the next higher level microwave which had a few more features and a higher capacity but it was out of stock so we settled on this model. Like most folks the microwave is one of the most used appliances in our kitchen. Weve had this one for a few months and it has performed well. We generally dont use the sensor basked cooking options but weve tried a couple with this one and they do work about as expected. Basically results were slightly undercooked but this is desirable as opposed to overcooked. Our biggest complaints with this microwave I suspect apply to all LG microwave models. The control panel buttons are not backlit and the legends do not have enough contrast so theyre hard to read. We have found we have to have all the kitchen lights on in order to read the buttons. Theyre also difficult to press. They seem to be typical membrane type buttons but for some reason its hard to find the right activation spot so we find ourselves having to press a button several times moving our finger slightly each time until it finally registers the press. The other issue I have with it is the display. Its bright glaring white. There is no control to dim it. As I mentioned above we also bought other appliances so they would all match. The LG range which is below this under cabinet microwave has a nice blueish white display. The microwave display stands out like a sore thumb. Silly me for thinking theyd use the same display. I ended up ordering some colored gel material and cutting a piece to go over the microwave display. The colors still dont match but the microwave display isnt so harsh and doest stand out like it did before. The only other issue I have is the light provided on the bottom presumably to illuminate the stove top below is so weak its almost useless. I was able to find a much brighter LED replacement on Amazon. Overall were pleased with this LG microwave.

fastmike 9/16/2022

The most obvious concern we have with the unit is how hard you must push the keypad for use. Not like any other unit we have used. Calling it Touch Pad would be incorrect. Additionally the keypad is very dark. In a dimly lit kitchen its very hard to read the keys. Should be backlit. The microwave functionality is fine but thats what you expect

MSgtLarryK 9/11/2022

I recently bought this microwave to replace a competitors brand. We chose LG due to the features and the fact that we have replaced all our kitchen appliances with LG. We use our kitchen hard and LG has always outperformed others. This microwave has already demonstrated performance that has surpassed our previous microwaves Outstanding

Control panel hard to read

Brand71 9/1/2022

The microwave itself is fine. I use it only for basic microwaving tasks. However the control panel is very dark and difficult to read at times I use a flashlight to illuminate it. I am very disappointed in that respect. I will have to buy a stick on LED light to place above the panel to make the controls more visible.

Wish I had done my homework before buying

Lisa Loundagin 8/15/2022

I was excited to purchase my first LG appliance but I am definitely disappointed with this microwave. The worst is that the keypad is nearly impossible to see especially when its darker in the room. This thing is also the loudest microwave Ive ever used and you have to push too hard on the buttons to get them to work. Finally a high/low option on the light would be a nice feature. The microwave seems to heat food well but based on the above complaints I would not recommend this and am already regretting my purchase after just a few days.

Clock wont stop blinking

Margaet Henne 8/14/2022

I bought all new LG appliances from Home Depot including microwave model LMV1831ST in July 2021. Today the microwave clock light will not stop blinking and it is out of warranty. It is August 2022. They wont fix it unless I pay for it myself since the warranty is for 12 months. BUYER BEWARE I think 12 months use is a very short time and LG products should work longer than 1yr. Very unhappy with LG.

LG does it again

mmtc 8/11/2022

This was a replacement for slightly smaller model due to our kitchen renovation. There have been several tweaks since we bought the other one. One my husband is thrilled about is the ability to stop the turntable. I am happy that there is a separate timer. The only downside we have encountered is the inability to lower the volume on the end of cooking alert... it seems really loud. But we can definitely live with it because this unit works great

Horrible LG Experience

DF2022 8/3/2022

We purchased an LG microwave in November of 2021. Within the year the control pad began to flicker and then went black. LG came out to repair in late 2021 since it was still under warranty. Within 7 months the repaired control pad is now flickering as the first one did. However LG will not fix the unit this time since it is out of warranty. Yes they are technically correct however the repaired unit broke within its first year of getting fixed. We purchased 5 LG appliances in November of 2020. 3 out to the 5 appliances have required repairs.

Michette 7/23/2022

the control panel button are to dark and I have to use a flashlight to see them. On your picture you can see them on the microwave you do not see them. I am very disappointed about this purchase. Therefore I would not buy another one and would have returned if it was not hard to remove.

Good microwave

Janw68 7/23/2022

Bought this last month. One problem I have with many products that need to be installed is they dont have a standard installation no matter the brand. I was replacing a microwave in the same spot but I couldnt use the bracket I put in for the old one nor could I use the same holes in upper cabinet for the screws that go in the top. So new bracket and new holes had to be drilled. The other issue is the over the stove light under the microwave is very weak. I replaced the bulb with a LED bulb. The microwave does work good

An Excellent Over-the-Range Microwave

RTF70 6/19/2022

I purchased this over the range microwave last December. I bought this model in late December because my prior LG model which was over 10 years old stopped working and could not be repaired. There are many features on the new microwave which was not present on the prior model. We are and continue to be very pleased with our purchase.

Disappointed

dorisanne 4/17/2022

While this is a very good microwave but I was so disappointed that it didnt have the LG tune indicating the finish. I was so tired of that incessant beep my former microwave had that I was eager to replace it. Wish I could turn it off Another feature I miss is the express cook feature. Simply pressing one number to start cooking was a feature I regularly used and miss it. I admit I didnt do my homework before purchase. Now to the features I do like...the quick defrost and timed defrost are both effective doing the job without cooking the item. The sensor reheat is also effective leaving the food nicely heated. I also like the add/subtract 10-second feature.

Looks so pretty

Bonnietds 4/11/2022

Overall the microwave is super attractive and looks awesome above the new LG stove below it The keypad is dark though and hard to read and I also feel like the buttons are fussy to use sometimes having to push a number twice for it to detect. The Grey interior is also dark so feels like a little cave. Wish it was brighter or had more light to illuminate whatever we are heating. Lastly the bulb for the over the cooktop light located in the bottom of the unit put out so much heat that we could feel the warmth on the inside of the microwave below glass plate therefore making us nervous to use as a night light as we had hoped. We changed it to an LED which seems to be working just fine.

There are two things that we would change. First the programming panel is not back-lit at all which makes it more difficult to see without a bright kitchen light being turned on. Secondly we are used to our previous microwave displaying a number to choose with an abbreviated food item when using the sensing cook mode. I had to make a copy of the Sensing Cook mode selection recommendations and put in the cupboard with this microwave .
