Operation Overview - GE Profile PHB925SB1SS Technical Service Manual

The controls for the oven system consist of a
key panel touch-fi lm-on-glass assembly and
main logic board with its model-select resistor
plug located in the control panel. There is also
one RTD oven sensor, optional meat probe,
and a motor door lock assembly with position
switches. The oven and warming drawer are
controlled by relays found on the RPSM main
board.
There are four induction cooktop coils. The
controls for the cooktop module consist of
two burner touch boards connected to and
working through the main logic board. The
main logic board is connected via the local
interconnect network (LIN) serial wire to the
cooktop module and a relay power supply
board (RPSM) located on the back of the unit.
A fi fth cooktop element is a resistive warmer
controlled by RPSM relays. (See
.) No relay boards or line
and Wiring Diagrams
voltage are brought to the control panel.
The bridge board contains the surface on/
hot cooktop indicator lights. The induction
module cooling fan connection is also located
on this board. This board bridges the Linbus
connections from the fi lter board and main
logic board along with the RPSM.
