The LG WCEP6427F is a combo wall oven that pairs a TurboCook speed oven with a lower oven. LG lists Infrared Heating, convection in both cavities, air fry, steam baking, roasting, steam sous vide, backlit SmoothTouch Glass Controls, and ThinQ support.
With steam functions in play, we check water-related parts as well as heat. We confirm that the steam mode is making steam, check the supply path, and look for mineral buildup. On the heating side we test the infrared system, the convection fans, and the elements. The speed oven’s door switches are tested because the cavity will not start without them.
The glass controls are checked for a clear response, and the app link is tested at the unit. We take the model and serial off the label first, then order the matching part. You see a written price first, and repairs include a 30-day workmanship warranty.

What do you check if steam sous vide does not work?
We confirm that the oven makes steam, then check the water path and any buildup. Steam modes need water and heat together, so we test both before quoting.
Why would the speed oven not start?
A speed oven will not begin unless the door latch and switches register closed. We test those first, then move to the heating parts, and give a written price.
Can you repair the backlit glass controls?
We test the panel, its connection, and the control board. If the panel is dim or does not respond, we explain which part is needed and its price before doing any work.
