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.

Flaking Blue Enamel

Bob629 7/26/2024

I have owned the previous model WDEP9427F for about a year and it was purchased as part of a kitchen renovation. It has actually only been in service from November 2023 to July 2024. Large areas of the oven are flaking blue enamel and this is getting in the food we bake in the oven. Customer service said it was cosmetic damage and not covered by warranty. I told my guest that the blue enamel flakes in their cake was courtesy of LG Customer service.

No service for issues/problems available.

Isidro C 7/11/2024

After first time use of the oven the middle glass pannel had grease enter into it. There is not way to clean it. I have contacted LG service directly they are having a difficult time finding a service provider to come see/fix it. I have spent too much time on the phone with them. We got our oven in May. Very dissapointed.

Awful customer service

KHughes67 11/8/2023

I was very excited about our double oven but we are now having problems with the bottom oven starting the door is open when it is clearly closed. This makes it where we cannot use the lower oven but the real problem is the awful customer service. Over 10 days after reporting no one has come out to repair or look at the appliance.

Great installation + features

joshfi 9/13/2023

We replaced our old microwave + single oven with the LG Studio double oven. The cutout dimensions were spot on. We were able to modify our existing cabinet to fit the double oven just fine. It works great. We love all the features and the touchscreen interface plus app really add to the experience.

Like having a personal chef kinda

Ovey1 8/3/2023

If you are the household which that has a stay at home that prepares all the meals but can burn water this is the oven for you. The automatic cook functions make the cooking process fool proof. Everyday I would get a call from the wife asking how to cook this or how to cook that. How long do I cook it for. I dont think this chicken is cooked. Now select what you cooking put in the thermometer and wham b thank you maam youre done. Install was easy and the oven looks great

Excited but then let down

mkmorgan11 3/14/2023

We bought this LG wall oven as part of a remodeled kitchen in our new older home. I was so excited to be able to give her a double wall oven with all the bells and whistles. The most exciting part was having an oven size air fry feature. After using this four or five times with the air fry feature It did not work like an air fry oven. You turn it on you have to wait 15 to 20 minutes before the fan actually starts circulating the air in the oven. Totally defeats the purpose of a quicker cook time. When you air fry it is said that you dont have to defrost items that you place in the oven. You can instantly start cooking because the air circulates but only the LG double wall oven does not. I even had a technician come out and check it out for me. Ive learned thetemperature is set and after a few minutes it reaches its desired temperature. After about 10 minutes the exhaust fan comes on and then 5 minutes later the air fry fan comes on. So youre looking anywhere between 15 and 20 minutes to get to the air fry feature. Dont get me wrong its a beautiful oven but totally disappointed especially at this price

LG Double oven with steam assist

My9428 1/20/2023

Have had this oven for only one month so we are still exploring its varied functions. Love the style both in and outside and the control panel as well. Made a standing rib roast that was thoroughly enjoyed. Did one steam assist bread that came out nice but need more attempts to be fully satisfied with this function. Only disappointments so far is the soft close doors which fail to close completely on their own. Wonder if I need to call for service b/c of this issue. Lastly but importantly not happy the price dropped several hundred dollars a week or so after we purchased it.
