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:
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
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.
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
Place a protective cover on the main top of the 3.
oven.
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.
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.
