What is true of this model and changes how you fix it
- Hardware — LG product pageSINGLE wall oven only, no microwave section (unlike the WCEP6423) and no cooktop, 4.7 cu ft, Fan Convection, AirFry, ThinQ app with scan-to-cook.
- Type — single WALL OVEN (no cooktop)A single built-in WALL OVEN — oven only, no cooktop or burners, so cooktop/burner symptoms do not apply. Installed in a cabinet, paired with a separate cooktop.
- Oven — electricElectric oven with ProBake convection and Air Fry on most builds. No-heat is the bake/broil element or control. A dead unit is often its dedicated circuit breaker.
- Self-clean & featuresEasyClean/high-heat self-clean (door locks, some smoke normal on high heat), ThinQ Wi-Fi on smart builds.
- An oven onlyIt sits in a cabinet and is paired with a separate cooktop.
- Electric heatingThe oven heats with electric ProBake elements and a convection fan, and AirFry on most builds. A cold oven is the bake or broil element or the control, and a dead oven is often its dedicated circuit breaker.
- EasyClean and self-cleanEasyClean and a high-heat self-clean lock the door, and some smoke is normal on high heat. A door that stays locked after a clean is waiting for the oven to cool.
- ThinQ and scan-to-cookOn smart builds the ThinQ app can monitor and control the oven, and scan-to-cook reads a package code and sets the cooking. It depends on a 2.4 gigahertz network.
- The touch panelThe control panel can be locked and reads best with clean, dry fingers. A locked or wet panel is the commonest reason it seems dead.
- AirFry modeAirFry uses the convection fan and high heat to crisp food. Use the perforated tray and a single layer, and keep the door closed, since opening it lets heat escape and slows the browning.
- Sabbath and demo modesA mode that disables normal heating can make an oven look broken. Check the display for a Sabbath or demo indication before calling for service.
- Cavity size and racksThe oven is sized for a wall cabinet and holds several racks. Use the center rack for most baking, and lower or higher racks for roasting and browning.
- Using the display and the wireless featuresThe display shows the set temperature and the actual one. If the display and the oven disagree, check for a Sabbath, demo or locked setting before assuming a fault.

Exact questions
Questions that only have an answer for the LG WSEP4723 wall oven
My LG WSEP4723 wall oven is completely dead.+
A totally dead built-in wall oven is most often its power supply — check the dedicated circuit breaker for the oven, which can trip and kill the whole unit. Confirm any clock/display is blank (no power) versus lit but not heating (a control or element issue). Because it is hardwired on its own circuit, there is no plug to check; the breaker is the first stop. There is no cooktop on this unit to consider.
