Introduction
Monogram introduces the new GE Professional Wall Ovens. Their superior style and performance parallel
commercial ovens. Available in two design choices -- integrated and professional -- these ovens feature
electronic dial controls that combine the precision of modern digital technology with the simplicity of
traditional mechanical controls.
6 electronically controlled heating elements --
•
two bake, two broil, and two convection -- provide
precise cooking control with fast preheating.
Reverse-air convection technology utilizes a
•
bidirectional fan that works with a dedicated third
heating element to promote even heat circulation.
Performance compensation for 208-volt
•
installation boosts power as needed in multifamily
dwellings.
4.4 cu. ft. total capacity.
•
Recessed convection, low-profi le broil elements,
•
and hidden bake elements.
Halogen light columns located on both sides of
•
the oven interior.
Full-extension, self-cleaning porcelain-coated
•
racks that can be left in the oven during the selfclean cycle.
Hidden bake element, which is concealed
•
beneath the oven fl oor, allows quick and easy ash
removal following the self-clean cycle.
Both Monogram wall oven designs are available in
•
single and double confi gurations.

Your oven has additional Special Features that you
may choose to use.
They remain in the control’s memory until
the steps are repeated. The Special Features
will remain in memory after a power failure.
Either the Oven Mode knob and/or the
Temperature knob must be turned
to OFF.
You may find that your new oven cooks differently than
the one it replaced. Use your new oven for a few weeks to
become more familiar with it. If you still think your new
oven is too hot or too cold, you can adjust the thermostat
yourself.
To adjust the oven thermostat:
1 Push and hold the PROBE and DELAY START
buttons at the same time for 4 seconds until the
display shows SF (Special Features).
2 Push the PROBE button. A “0” will show in the
display.
On double wall oven models, a “0” will show in
both the upper and lower oven displays. Push the
PROBE button a 2nd time (“UPPER” will show in
the display) to set the upper oven, and push PROBE
a 3rd time (“LOWER” will show in the display) to
set the lower oven.
3 Turn the Mini-Knob to adjust the oven
thermostat up to 35°F hotter or (-) 35°F cooler
in 1°F increments.
4 Push the Mini-Knob to enter your choice.
On double oven models, either the Oven Mode knob or
the Temperature knob will have to be turned to OFF for
each oven.
NOTE: While in the Special Features mode, if the
Mini-Knob is not pushed to enter a choice after 60
seconds, the mode will be cancelled (without changes)
and the time of day will return to the display.
The following are the features and how you
may activate them.

time of day clock.
Do not use thermometers, such as those found in
grocery stores, to check the temperature setting of
your oven. These thermometers may vary 20–40
degrees.
NOTE: This adjustment will only affect baking
temperatures; it does not affect broiling, convection
or self-cleaning temperatures. The adjustment will
be retained in memory after a power failure.

baking/roasting only. It cannot be used for
convection, broiling, self-cleaning or Delay
Start cooking.
When the Sabbath Feature is set, the
oven light and all audible beeps will be

Sales Mode
The oven control can be operated in SALES MODE.
When the unit is connected to 120 VAC from L1–L2,
the control will function normally. The 240 VAC
relays will not function.
Operational Notes
Certain modes, when selected, will automatically
enter into a preheat. The PREHEAT light will turn
on and 100°F will appear in the display. (The
temperature display will start to change once the
oven temperature reaches 100°F.) The convection
fan will turn on several seconds into the preheat
cycle and remain on until the oven has reached the
set temperature. The control will beep when the
oven is preheated―this will take approximately 10
to 15 minutes. The PREHEAT light will turn off and
the display will show the set temperature.

Std Broil No
Clean No
Probe Usage No
Different broil elements are used in each broil
•
mode. There are 3 different broil modes, each
providing a HI and a LO setting.
The Dual Broil mode uses both the inside and
•
outside broil elements.
The Standard Broil mode uses the inner element
•
only.
The Convection Broil mode uses both the inside
•
and outside broil elements and convection fan.
Broil will not work if the temperature probe is
•
plugged in.
When using the probe, you can use the timer,
•
but you cannot use timed oven operations.
On the double wall oven, the oven control will
•
automatically set the oven that has the probe
plugged into it.
In Convection Bake, the rear bake element and
•
the fan operate whenever the oven is heating.
Convection Broil will not work if the temperature
•
probe is plugged in. Never leave your probe
inside the oven during a broil cycle.
On the double wall oven, you can use timed
•
baking in both ovens at the same time. Turn the
Oven Mode knob and the Temperature knob of
the second oven to the desired settings. Push
the COOK TIME button and turn and push the
Mini-Knob to enter. Push the DELAY START button
and turn and push the Mini-Knob to enter.
Preheat operation consists of multiple phases
•
which are time and/or temperature dependant.
Each phase of preheat utilizes combinations
of inner and outer bake, broil, and convection
elements. For example, one phase may use
inner convection, outer convection, and outer
broil simultaneously. Another phase may use
inner broil and outer bake simultaneously.
The oven and the oven interior lights will turn on
•
immediately and stay on until the oven is turned
off.
The convection fan will cycle on and off while
•
cooking to best distribute hot air in the oven. The
convection fan shuts off when the oven door is
opened.
A cooling fan will turn on to cool internal parts.
•
This is normal, and the fan may continue to run
even after the oven is turned off.
•

The Clean cycle can be set for a minimum of 3
hours and a maximum of 5 hours. The default
setting is 5 hours. The 5 hour set time consists
of 4 hours and 20 minutes of cleaning and 40
minutes of cool down. The door will unlock at an
approximate temperature of 450°F.
On the double wall oven, you can set a clean
cycle in both ovens at the same time. The last
oven set will automatically delay its start until
the fi rst oven's clean cycle cools to 400°F. On
the double wall oven, you can bake or broil in
one oven and self-clean in the other at the same
time.
Self-Clean will not work if the temperature probe
is plugged in or if the Sabbath feature is set.
Proofi ng will not operate when oven is above
125°F. The display will show “too hot”. Allow the
oven time to cool.
