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.

Microwave caught fire Poor customer service

CAChef 11/4/2025

My 18 month old microwave caught fire last month hearing a cup of coffee. Not in the cooking chamber but the enclosed motor. Thankfully I was standing nearby and also had a fire extinguisher. My experience replacing this faulty unit has been inexcusable bad. An original delivery date of 11/3 was not met after taking off a day of work later rescheduled twice in 1 day for no obvious reason to 11/10. I remodeled my home installing all LG appliances tv washer/dryer. After this experience I am regretting that choice

Junk customer service is terrible

Rickp63 8/18/2025

Used this microwave for 2 months and it died. Been waiting for a replacement for 4 months all Im getting is the run around from lg. Customer service is crap Lies on top of lies It was condemned but the engineering department but no record of that in the customer service department. Ive contacted the BBB I guess its an attorney next

Microwave with convection and air fryer options.

markian12 12/1/2024

We have used this with the microwave convection oven and air fryer. I thought it was supposed to cook foods faster than a conventional oven but have found it takes the same or longer with the convection feature. Also I was supposed to get an additional year warranty. I submitted the paperwork that I had an email confirming the online purchase. This is all I received with the online purchase from Home Depot and it was rejected as not enough.

HORRIBLE product.

JudyWI 11/21/2024

This is the worst microwave I have ever purchased. The soften butter feature literally melts a stick of butter the so-called feature to reheat a plate of food dinner plate far overheats it the front panel lights are dark gray print against a reflective black background and impossible to see. No nightlight feature either like on my old GE. This is 2024 - you should be able to have all your selection menu items show up electronically instead of having to open the door and find them - and those selections are also dark gray print on black. I have to use a flashlight to see them. So hugely disappointed. I can only hope it dies before my 5 year warranty. Will probably go back to GE.

Sit down and wait

William Perez 10/23/2024

I bought stove refrigerator and wine cooler in September 2024 and i have still not received it. I cant register the warranty because we are at the end of October and the 30 days are up. I dont have the information or the paperwork to register my appliances for the warranty.

Horrible customer service

PilotWerx 8/28/2024

Have tried for 6 months to get a call back about the microwave. Works fine when the plate spins in one direction but makes a thumping sound spinning the other way. Here is my last try. Either someone reaches out or I am going to purchase another one and return the original in the replacements box.

LG Under range 1.7 microwave

GJoanne 5/4/2024

I purchased this LG microwave and have used it about two weeks. So far everything is great. The one comment I would make that they could improve on the grease filters on the bottom of the microwave. They were extremely portly made.

Works as it should accept for the WiFi. No amount of screwing around on my part can make the iPhone app talk to the microwave.

Wont buy again

Dissatisfied chef 3/5/2024

Overall it does what a microwave does. Major two complaints are that the fan doesnt suck up any steam coming up from the stove. Yes we verified it is in the correct way. So the majority just cones up the front of the microwave and makes it extremely wet with condensation. The second issue is the clunking sound when the turntable goes around. Yes we cleaned everything verified position etc. All the useless tips they have. We have been an LG fan for years but between this and other LG appliances I doubt we will ever buy again. The quality of the products extremely dropped over the years.

Fantastic Features

Douglas G Duggar 1/19/2024

We love our LG Microwave/Convection oven. We use it almost daily to either warm up a snack or a cup of hot tea or warm up a cup of coffee. I addition I love baking fresh bread and always wanted a proofing oven. Now I have one and it works perfectly. I havent had the opportunity to make my sour dough yet but I will be within the next week or two and Ill let you know how it went. Douglas D.

The all-in-one

Jerry7988 1/14/2024

The all-in-one as I call it can cook just about anything you can think of. I like the quiet notification sound wotj food is ready and not loud constant beepiing. I must admit it takes time to learn which option Microwave Air Fryer or Convection oven. Air Frying hot wings is the best part for me.

LG Microwave Features

Douglas G Duggar 1/14/2024

We love our new LG microwave and the many many new features it has over the GE Profile we previously had. We are still learning about all the exciting features LG built into their Microwave especially the Convetion Oven feather for my wife and the Proofing feather for me as I bake bread of all kinds especially during the cold winter months. Thank you again.
