Similar to previous models where a full size microwave was integrated into a 27 in. or 30 in. Wall Oven, the
new design also incorporates a GE Advantium® version.
The ovens are built on the 2013 Wall Oven design, thus servicing them will be the same with a few
exceptions.
Lower oven does not have a service mode.
A RJ-45 connector is available for service and/or software updates.
Only uses Machine Control oven control.
An added "Bridge Board" is used to communicate between the upper and lower ovens.
For Microwave or Advantium® service, the upper oven is a "module" that can be slid out for service.
Service harness extension (Part #: WX05X24267) is available to enable the upper oven to be serviced and
tested outside of its enclosure.
Time of day display location may change. This is normal operation to preserve display brightness.
This service guide will show the more complex version of the upper oven. The Advantium® model has more
components. The lower oven is based on the present production model of a single wall oven.
