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.

Microwave lasted only 4 years

EstelaPC 1/28/2025

Bought this LG microwave for $379.99 and it worked fine for 4 years. However it stopped working and LG wants to charge $400 for repairs. This is frustrating as the microwave only lasted 4 years and now Im being asked to pay more than the original cost for repairs. Definitely not the quality I expected for a product at this price. Will not be buying from LG again.

Failed Flickering Screen

Hossam 1/6/2025

Like so many others left bad reviews the Flickering display board This is the third time The first time the replaced the whole unit because board was not available. Second time the replaced the board which failed again few months later. The unit is out of the one year warranty It is clearly a manufactured defect of the microwave with constant complaints from most customers. Would not recommend it. LG MUST ADDRESS THIS PROBLEM AND REPLACE ALL FIALED BOARDS REGARDLESS IF STILL IN WARRANTY OR NOT.

Clock/Timer Display Flickers Hard Press Buttons

Erik123456 12/29/2024

The microwave oven is not terrible but it does have issues. Most problematic is the clock/timer display that flickers. The flickering came on gradually and by the time it became annoying the warranty period was up. Also the amount of pressure needed when pressing the buttons is noticeably more than expected based on experience with previous microwaves. You have to press hard to make sure the oven senses the press.

Replaced The Digital Display Three Times

Joe 243 12/27/2024

Owned this microwave for only 2 years and I have replaced the digital display three times and the one currently installed began flickering within two months. I purchased a kitchen suite of LG appliances and I am so frustrated LG will not replace a defective part after so many failures. The display suffers from poor design and/or poor quality manufacturing. LG should pay the cost to have these displays replaced not their customers.

Not Reliable and Not Durable

Tony Impellitteri 10/14/2024

The LG LMV1831SS microwave I have was manufactured in 12/2021 and is 2 years and 10 months old as of this review. At less 1 year old the display began to flicker. This has gradually grown worse and is now at the point where all digits flicker rapidly. The microwave will still function but it is unsightly and clumsy to use for timer functions etc. After looking at this microwave a repairman stated that he could not get parts for this unit for that bit of information I was out 200 dollars. The only way that I believe LG can make this situation right is to replace it with an equivalent unit free of charge to me including installation labor. Right now I would never recommend an LG brand of appliance to anyone. I would have left a 0-star review but that option was not available. I doubt that anyone from LG will reply but this review includes my email.

Total waste of our money.

Rich Ga 8/26/2024

Purchased the microwave stove and fridge. The microwave display has not worked correctly since day one. The numbers for the clock just make circles. Now part of the display doesnt work. Complete garbage. The stove has had issues since day one. You cant use the oven with the timer because it just turns off randomly. Service guy said it is an issue with the main control board. He said he only gets used boards so if he replaced it we might have other issues. LG said we should just buy a timer and not use that feature. Never buying LG garbage again.

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.

LED Display Fails

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

Broke within 2 years

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?

Solid microwave but the display goes wacky

Steven Puri 6/20/2023

I bought this August 2021 and it had display flickering for a while but I thought it was my eyesight. I finally started taking videos with my phone and checking them and yes indeed the display goes wacky every now and then. Other than that it works great.

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.
