Generator Boards
To remove the generator boards:
Remove the heat shield. (See
1.
Heat Shield
.)
Note:
The thermal cut-out on the right and left
generator boards on the 30-in. model and on the
center and right generator boards on the 36-in.
models are joined together with 2 metal clips. The
clips must be removed to replace either generator
board.
2. If applicable, use a small
fl
at blade screwdriver
to pry up and remove the 2 thermal cut-out
clips.
3. Mark the location of the black L1 and the blue L2
wires and disconnect both from the generator
board.
Note:
When replacing the L1 and L2 wiring
connecting the
fi
lter board to the generator board,
connect that wiring in a matching con
fi
guration. For
example, if the L1 output is connected to the bottom
terminal on the
fi
lter board, it must be connected to
the bottom terminal on the generator board.
4. Disconnect the LINbus connector. (See
LINbus
Connectors
.)
5. Note the position of the thermal cut-out and pull
it out of the heat sink
fi
ns.

6. Remove the two T-15 Torx screws that hold the
generator to the module base.
7. Lift the heat sink side and slide the generator
board away from the 2 tabs on the module
base.
Thermal Cut-out
The thermal cut-out is located between the
fi
ns of
each generator board heat sink and is connected
to the
fi
lter board with a wire harness. The location
of the thermal cut-out allows it to sense an over-
temperature condition of the generator board.
The thermal cut-out has a resistance value of less
than 1
Ω
and opens at approximately 250°F. An
open thermal cut-out will stop operation of the
cooktop. If the thermal cut-out is open, check for
proper operation of the fan and possible vent
obstructions.
