Introduction
GE's second generation Profi le 30-in. free-standing double oven range is available with convection cooking in
the lower oven. These ranges feature electronic oven and surface unit controls that combine modern digital
technology with ease of operation. Their superior style and performance parallel many commercial ranges.
Electronically controlled oven heating elements - provide precise cooking control with fast preheating. •
Convection mode uses reverse-air convection •
technology - 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.
6.5 cu. ft. total capacity.•
Cooktop locked out during self-clean.•
New motorized self-clean door latch.•
Recessed convection, low-profi le broil elements, •
and hidden lower oven bake element.
Full-extension, self-cleaning, porcelain-coated •
racks that can be left in the oven during the selfclean cycle.

Control Features
Cooktop Burner Controls
To use the cooktop burners:
Touch the 1. ON/OFF pad for the desired burner.
Use the +/- pads to select the desired power setting. Nineteen power levels are available (L, 1 through 9 2.
with ½ step increments, and H).
Touching the 3. MELT pad selects the low setting.
Some burners have multiple cooking zones. Touching the 4. BURNER SIZE pad after the burner is on selects
the desired burner size. If no selection is made, all cooking zones for that burner will be on.
Touch the 5. ON/OFF pad again to turn the burner off.

Griddle Burner Control
Griddle temperature is regulated by an algorithm built into the control. It takes into consideration the mass
of the griddle, temperature selection, and the on/off times of the front and rear burners to approximate the
customer setting, but it will vary somewhat with the quantity of food on the griddle.
Note:
Use only the griddle pan provided with the range.•
The non-stick coating on the griddle will degrade if exposed to temperatures above 550˚F.•
Do not clean the griddle in the self-clean oven.•
To use the cooktop griddle control:
Touch the 1. ON/OFF pad.
Use the +/- pads to select the desired temperature setting. Temperature settings range from 200°F to 2.
400°F in 25°F increments. The default setting is 375°F.
“PrE” will be displayed until the desired temperature is reached. The left front and left rear burners will 3.
cycle to maintain the selected temperature.
Touch the 4. ON/OFF pad again to turn the cooktop griddle off.
375
Self Clean
The self clean procedure on the double oven is virtually the same as on the pervious version with one
exception. When in clean mode, the cooktop is still locked out, but instead of using a cooktop lockout relay,
lockout is done electronically by the main logic board.

Installation
Sales/Demo Mode
The demo kit model number is PB978 Demo Kit - Electric Ranges with Backlit Touchkeys. The cord is available
as Pub 3-A029. There is no change to the cord; the only difference is how the cord is attached to this model
range.
The following features are disabled in Demo Mode:
Oven heating elements•
Surface burners•
Convection fan•
Door latch motors•
Caution: This kit must be installed by qualifi ed personnel only.
To install the demo kit:
Disconnect the ground strap from the range body (the strap must not contact the range structure or the 1.
ground wire).
Connect the green wire to the range body using the grounding screw.2.
Connect the single black wire with ribs or the gray stripe wire to the left terminal of the junction box.3.
Connect the larger of the two smooth black wires to the right terminal of the junction box and the smaller 4.
of the two smooth black wires to the center terminal.
The cord is to be plugged into a 120V, 60 Hz polarized and grounded outlet.5.
To remove the demo kit:
To reverse the above process, ensure that the ground strap is reconnected to the range body using the
grounding screw.

Thermal Cutout (TCO)
The upper and lower ovens are protected by a TCO
mounted on the rear of the cabinet. The TCO will
open if temperatures on the rear reach 150˚C/302˚F.
The TCO is a "one-shot" device and is not re-settable.
If open, all oven elements will be disabled.

Hidden Bake Element
Before disassembling the range to access the
hidden bake element, check the resistance of
the element by disconnecting the plug and
checking between the orange and yellow wires.
The resistance reading of a good element is
approximately 21.7Ω.
If the hidden bake element does need to be
changed, the procedure is the same as for the
previous version of the dual cavity oven.

Control Panel Assembly
Control Panel
The controls for the oven system consist of a key
panel touch fi lm on glass assembly and a main logic
board with its model select resistor plug located in
the control panel.
The controls for the cooktop elements consist of
two burner touch boards connected to and working
through the main logic board.
The main logic board is connected via the LIN
serial wire to the Relay Power Supply Board (RPSM
Main) located on the back of the range, along with
a second relay board (RPSM Aux) and a smaller
Daughter Relay Board (DRM).
There are also RTD oven sensors and motor door
lock assemblies with position switches.
The upper and lower ovens are controlled by relays
found on the RPSM Main and DRM boards. (See
Wiring Diagram.)
Cooktop elements are controlled by relays found
exclusively on the RPSM Aux Board. (See Wiring
Diagram.)
No relay boards or line voltages are brought to the
control panel.
To remove the control panel:
Grasp the control panel and pull the bottom out, 5.
then lift the panel off the top 2 screws.
Place the control panel in the service position.6.
Service Position
Capacitive Touch Glass
A capacitive touch switch consists of two conductive
layers on opposite sides of an insulating material,
such as glass.
The 2 conductive layers create a capacitance that
decreases when a layer is touched by a human
fi nger.
Pull the range out approximately 6 inches from 1.
the wall.
Remove the fi ve ¼-in. hex-head screws that 2.
hold the top of the rear panel to the range.
Rear View
Place a protective cover on the main top of the 3.
oven.
4. Using a stubby or off-set Phillips-head
screwdriver, remove the 2 inverted screws that
attach the bottom of the control panel to the
range.
Interface circuitry is used on a touch switch to
convert the capacitance change into a usable
switching action to drive logic systems or to switch
analog signals.
To remove the capacitive touch glass:
Remove the ¼-in. hex-head screw that attaches 1.
the ground wire to the oven frame.

The main logic board is located inside the control
panel. The left- and right-side ribbon connectors
are replaceable components. The middle ribbon
connector is part of the capacitive touch glass.

Diagnostics and Service Information
Main Logic Board Failure Codes
F-codes are not shown on the display when they occur. They are stored in eeprom and can be retrieved by
pressing the TIMER ON + CLOCK + UPPER START pads together. The display then shows F-cd and prompts
for an UPPER or LOWER selection (1 is the upper oven and 2 is the lower oven). After an oven is selected, a
log is shown. Details of any one of up to 7 stored codes can be recalled by pressing a number pad. Press the
CLEAR/OFF pad to exit. The F-code log can be erased by pressing the 9 and 0 pads together while the log is
showing. (Only the log displayed is erased/cleared.)
Note: For the fi rst 3 minutes after power on, the F-code will show on the display.

Touch each pad. Pads should light in response, except CLEAR/OFF and COOKTOP Pads. Each pad must be
individually tested. Number pads, +/-, etc., respond only after a function is selected.
LIN Test
Press the OVEN LIGHT pad. Corresponding relay(s) should click and oven lamps should respond. If successful,
LIN bus is not the cause of nonworking elements.
Test Mode
The entry to the test mode is available for 3 min. after power up by pressing 1 and 5 pads together. The
display will switch to "tEST".
Pressing the CLEAR/OFF pad exits the test mode.
When a test feature is selected, it remains for 10 seconds, then returns to the "tEST" standby.

The current software version of the main logic board will cause the cooktop to become inoperative if either of
the sensors open.
If either sensor opens and the fault code sets to epprom memory (this takes about 3 min.), the cooktop will
become inoperative until the sensor is replaced.
