Surface burners•
Convection fan•
Door latch motors•
Caution: This kit must be installed by qualified personnel only.
To install the demo kit:
Disconnect the ground strap from the range body (the strap must not contact the range structure or the1. 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 block.3.
Connect the larger of the two smooth black wires to the right terminal of the junction block and the4. smaller 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:
Reverse the above process, ensuring that the ground strap is reconnected to the range body using the
grounding screw.

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 oven.

Control Panel Assembly
Control Panel
The controls for the oven system consist of a key
panel touch film 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).
There is also an RTD oven sensor and motor door
lock assembly with position switches.
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:
Pull the range out approximately 6 inches from1. the wall.
Remove the six 1/4-in. hex-head screws that2. hold the top of the rear panel to the range.
Remove the ground screw.3.

5. Using a stubby or offset Phillips-head
screwdriver, remove the 2 inverted screws that
attach the bottom of the control panel to the
range.
4. Place a protective cover on the main top of the
oven.

2. Remove the main logic board. (See Main Logic
Board.)
3. Remove four 1/4-in. hex-head screws that
attach the glass to the frame.
4. Lift the glass from the frame.
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
finger.
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:
Place the control panel in the service position.1. (See Control Panel.)
Main Logic Board
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.
To remove the main logic board:
Place the control panel in the service position.1. (See Control Panel.)
Mark and disconnect the 2 wire harnesses,2. mode/select plug and 3 ribbon connectors.
Remove the two 1/4-in. hex-head screws that
attach the board to the metal frame.
Note: Make sure to transfer the model select plug to
the new board before applying power.
