Most common issues on this model
- Air fry airflow and fan noise
- Uneven heat in either cavity
- SmoothTouch glass controls that miss presses
- ThinQ connection and alerts
The LG WDEP9423D is a double wall oven with convection in both cavities and air fry in the upper oven. LG lists SmoothTouch Glass Controls, a PrintProof finish, and ThinQ Care alerts. The WDEP9423F is a listed variant. It is built into cabinetry.
The upper oven works hardest here, since it does both baking and air frying. We test it first for element output, the convection fan, and the sensor, then compare the lower oven. Glass controls are checked for response across the panel, and the app link is tested at the unit.
If air fry results are weak, we look at the fan and airflow before the element. Because the D and F versions share a base number, we read the full model and serial from the label before ordering parts. A written price comes first, and the repair has a 30-day workmanship warranty.

Why is air fry weak on my WDEP9423D?
Air fry depends on the convection fan and element working together. We test the fan, the heating, and the sensor, then explain which part needs repair and its price.
Is the PrintProof finish affected by service?
We protect the finish during work and use gentle cleaners. The finish resists fingerprints, but harsh products can still dull it, so we take care around the oven face.
Can you fix glass controls that miss presses?
We first clean the panel, then test its connection and the board. If a part must be replaced, we give a written price before starting.
