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.

Bad design

RAD5 6/26/2025

Bad design. Actual temp not displayed in airfry. Preheat is slow gets to about 20 degrees then takes 20 minutes from there to set temp. Controls are not good. The app is a joke cant even turn on the oven unless you go to the oven and tell it to remote for each time.

LG oven software bug....please fix

happy2finish 2/1/2025

The problem I have found so far concerns the convection roast function on this model. For setpoints in the 435-450F range for both ovens after successful preheating when placing food-laden pans in the oven the oven CANNOT get back to setpoint and gets stuck at 420F and will not go any higher At temperature setpoints outside this range even 451F it works fine. LG service tech came to see confirmed the issue said its a software issue but had to close the service call because there was no hardware they could replace. So I wait for a software update that will fix this... Unfortunately im told software update are released very infrequently... I expect better from LG...obviously the software quality group failed here.

Flaking Blue Enamel

Bob629 7/27/2024

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.

Blue flaking paint enamel

I have owned the previous model WDEP9427F for about a year. It was purchased as part of a kitchen renovation and actually has only been in service from November 2023 to July 2024. Large areas of the bottom are flaking enamel and this is getting into the food we are baking in the oven. Customer service says it is only cosmetic damage and isnt covered under 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 7/12/2024

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.
