Most common issues on this model
- Convection fan noise or airflow
- One cavity that heats unevenly
- Display and touch control response
- Door gasket and hinge wear
Two cavities share 9.4 cu. ft. in the LG WDEP9421S, a double wall oven with convection and an electronic touch control. It is built into a cabinet tower, so most households use the upper oven for daily cooking and the lower one for larger meals. That makes uneven use between the two a useful clue.
We start by running each cavity on its own and comparing its heat against the setting. Next we check the bake and broil elements, the temperature sensor, and the convection fan. The door gaskets and hinges are inspected, since loose doors can cause uneven cooking. The touch control is tested for a clear response.
If only one oven is affected, the repair stays in that cavity. If both are, we look at the shared control and its wiring. We read the model and serial from the label before ordering a part for the WDEP9421S. A written price comes first, and the work is covered for 30 days.
Key features
- 9.4 cu. ft. double wall oven
- Convection fan in main cavity
- Electronic touch control with display
Why does my lower oven cook differently than the upper?
Each cavity has its own elements, sensor, and fan. We test them separately and compare temperature to setting, then price only the part that tests badly.
Can the door gasket be replaced?
Yes. If a gasket is torn or loose, heat escapes and cook times stretch. We inspect it with the oven cool and give a written price before any replacement.
What do you check if the touch control is slow?
We clean the panel, test its connection, and then the control board. If a part is needed, we explain what it is and what it costs before we begin.
