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.

Disappointing Experience with Ovens Failing

CherylH55 10/17/2025

I bought this oven in July 2024 and 14 months later it stopped working in the middle of baking something. Both ovens and the control panel stopped working abruptly. I loved this product up until then although I didnt really like the air fry option. Anyway I had bought a 5 year care plan on it and a couple other appliances. The repair person who came out to diagnose the problem said it appeared to be the main panel. I was told it would be ordered but then got an email and spoke to someone at Allstate the care plan managers and they said it couldnt be repaired and that I would receive a refund for the purchase price. So now I have to buy new ovens and pay again for installation etc. All my other appliances are LG but I will need to buy another brand for the ovens to feel confident Ill have an oven to use of the holidays coming up and for years thereafter. Really disappointed.

Love the oven/ air fryer but...

Carlene8 11/4/2024

I love my new oven/ air fryer. I choose to hire my own person to wire and install. While the product is great the customer service is not. Be sure to document everything when ordering. The product is definitely a very good oven however.

Unnecessary Problems

WantedBetter 10/7/2024

Had this oven installed in February 2024. It has a very nice exterior appearance. The interior looks like a standard oven but the shelf spacing made it difficult to fit two shelves worth of food on them. This oven lends itself well to shallow pans. Initial use was good but found that temperatures were inconsistent this includes temperature inconsistency based on interior thermostat versus a manual thermometer and inconsistencies between top and bottom heat. The oven includes a temperature offset but even adjusting the offset does not resolve all the issues. The bottom heats more than the top causing the bottoms of dishes to burn unless the temperature is reduced significantly e.g. 25 degrees. After using the oven for 7 months the top oven started making a very loud noise from the convection fan. Called for warranty service and the experience was surprisingly good. They were responsive and were able to troubleshoot the issue within a week. The repair man tried to adjust the fan but assessed that the fan motor needed to be replaced. Getting the replacement fan took about a week and he was able to replace the motor in about an hour. The repair man did a great job and was very professional. He mentioned that he replaces the top fan motors often on these LG ovens. Overall this oven is acceptable but given the temperature inconsistencies shelf spacing and the faulty fan motor I wouldnt recommend buying it due to the inconvenience of being without an oven for a couple of weeks and having to coordinate the repair even if it was a good repair experience - not needing a repair would have been ideal.

Very poor customer service.

Dom66 7/9/2024

So far Im pretty happy with the wall oven purchased in March of this year. I had to contact LG as the internal glass cracked and needed replacing as there must have been a fault during shipping up here to Alaska but after managing to convince a rather untrusting customer service rep there had been NO IMPACT and supplying video and still photographs for their assessment whereby they could see I was not lying it was assessed again by a local contractor glass ordered and replaced. This is the only reason I have marked them down as the oven is very good indeed. Its pretty unfair to be thought of as someone lying when your product complaint is their error.

Works great

Lori112 6/20/2024

Have only had this for about 2 months but am happy with how it performs. Seems to bake true. One thing I find a bit bothersome is that you cannot use the broil function with the over door open as I prefer to do Not a big deal really. Love the blue interior. Am still getting to know the ovens and have not tried the air frier yet. Also it does take longer to heat to temperature than my old one did.

ME TOO: NEW Double Oven Trouble NO Help From LG

Goodnerd 3/21/2024

I am also the victim of a shoddy product and how LG refuses to stand by their product. Our problem is on the upper oven also but with us we had large black stains appear all over the surface of the bottom of the oven after the first use. THESE ARE NOT FOOD STAINS - THIS IS BURNT ENAMEL UNDER THE EXTERIOR FINISH This means this will likely chip and crack because it was not properly coated. LG would not even come out or even call. They refused to do any warranty work and TEXTED me saying that their warranty does not cover cosmetic damage. This is a brand new oven It was used once and there are dozens of black burn marks on the inside now and the oven was only heated up to 375 for just a few minutes as we were cooking fillets. LG does not stand by their product at all. LG: If you had a brand new car and the paint started peeling after the first time you drove it would you accept that as just a cosmetic issue? Of course not - this is damage caused by a faulty manufacturer procedure. I am filing a report with the U.S. Consumer Product Safety Commission as this is not just a cosmetic issue.

Severe blemishes on oven bottom after only one use

v3games 3/19/2024

We just purchased this double oven a few days ago. It was used once and I am very well aware on how ovens work and these are not stains that are on the surface of the enamel. The top oven now has dozens of black spots with 2 of them measuring several inches in length. The only thing we cooked was a filet mignon that was in at 375 degrees convection that was in the oven for less than 10 minutes. These stains are not from splatters or drips on the surface The surface is still smooth as glass and these blemishes are appearing from the underside of the enamel. This is not the result of drippings. Nothing leaked splattered or was dropped on the oven bottom. At first there was just the 2 large ones so I tried heating up the upper oven to 350 this morning and now there are dozens more smaller spots. This was with nothing cooking in the oven as it was just preheat. This is totally unacceptable especially for an oven of this price. These are NOT food spatters These are stains showing up from the underside of the enamel. I tried to upload images but the site rejected them.

Oven Racks

AndrzejSop 1/23/2024

Oven by itself is great but........oven racks are garbage. Cannot have them inside oven while doing either easy clean nor self clean.If you do chrome plating will come off. So they get dirty and you the end user is stuck with hours of hard labor to clean them. I used to have GE oven with racks that I could leave inside the oven while running self clean cycle. I did not know about this LG junky racks up front if I did I would NOT buy LG.
