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.

Goldminer 5/21/2018

Had the 1813 4 years and it laid an egg. This is the only one that fit in the 1813 space. It is very noisy when in use. Makes terrific grinding noise. It is only 1000 watt so does not perform as well as old one. The light 1813 had 2 is so dim that you need to turn off room light to see whats cooking. The cook area is considerably smaller so things we used to cook in will no longer fit. Its bad

GreenGirl 4/29/2018

We bought the stainless steel one and it is pretty easy to clean like it says. It is also pretty quiet. It cooks the food nicely. It could use another light on the inside though there is only one on one side and the interior is dim. I also wish the outer light that is above the stove was brighter it is near the front though which is better than most.

First want you to know I already own an LG washer and dryer so I am usually very happy with LG products and my microwave is no exception The favorite feature about this microwave is the sensor button which cooks things without me having to know how much time is needed. Love that feature. Plus this is the first over the stove microwave Ive ever owned and I am so happy with the purchase. It has freed up a whole other counter space in my kitchen.

GGGMOM 10/11/2017

Cooks great. I Like several of the unique features including the popcorn and butter melt options. Both work great and I dont end up with burnt popcorn and spattered butter like I did with my old microwave My only complaint is that I cannot turn off the beeper. It is a bit loud and if you dont take your food out right away it will beep at you again reminding you that your food is ready. I find this feature to be annoying as our bedrooms are located near the kitchen and the beeping is very loud. Other than this one issue I really love my new LG microwave.

Good Micro at a Great Price But...

Foodii 9/22/2017

Ive been using this microwave for at least a year now and have a love-hate relationship with it. I love the powerful 4 speed exhaust fan with turbo boost the large turntable and interior space and the variety of auto settings to defrost reheat and cook. But the individual auto cook times are off so performance is lacking somewhat. My vegetables come out overcooked and my meat defrost settings tend to burn the outside edges. The displays layout needs improvement and simpler features i.e. a keep warm setting would be nice a one-button 1 minute timer instead of 30 seconds and laid out in groups by common tasks. There is no rhyme or reason to the current layout. I really wish there was a way to customize the settings so that my ingredients and meals come out perfect each time

No, I do not recommend this product

While we originally looked at the LG micro wave because it matched our appliances we soon discovered it was a great buy The speed of the unit its quietness capacity and builtin optrions sold us on the brand. The store where we bought it also installed it. Just watching this operation convinced us that we would have had no trouble doing it ourselves.

Perfect

Lynnae1 9/22/2017

I bought this to replace my old microwave that had a cracked in the door. It was plastic and just couldnt stand up to the heat and steam generated by my pressure canning activities. I expect my new stainless steel to do better. I dont cook with my microwave but this one has a few features that I love. The 1 button for 30 seconds. Perfect for warming a half cup of coffee or hit it several times for a whole plate of food. I enjoy the melt/soften feature as well for butter or cream cheese. This thing will do so much more than Ill ever need. Its beautiful for a microwave... and was priced right. It was so much easier than my old one to install. It had to be 50 lbs lighter Gotta love new technology.
