Caution: To avoid delivering an electric shock to
the new power board, place your hand on the
burner box for at least 2 seconds before reaching
for the new power board.
7. Remove the new power board from the anti-
static bag and reconnect the 26-pin wire har-
ness, the main power connector, and the burner
box power connector to their original positions.
8. Examine the inside of the cooktop (heaters,
sensors, wires, and thermal wall) for anything
that does not look normal.
9. Prop the glass onto the back of the cooktop.
Using one hand to lower the glass, use the
other hand to connect the wire harness from
GEA00826 the user interface to the 10-pin header on the
logic board.
10. Lower the glass onto the burner box, being
sure not to pinch any wires between the frame
and the burner box.
11. Apply power to the cooktop. Once the cooktop
appears to be in working order, remove power
from the cooktop and insert all the screws to
secure the frame to the burner box.
Calibration Instructions
for the Inductive Sensors
Note: Calibration of the inductive sensors must
begin with the LF surface element and proceed in
a clockwise direction around the cooktop. All of
the sensors must be calibrated to complete the
calibration procedure.
• Calibration of the inductive sensors must begin
within 15 minutes of applying power to the
cooktop.
1. Clear everything from the top of the glass.
2. Lock the control by pressing the control LOCK
key for 3 seconds. The control LOCK LED will
turn ON.
3. Enter tech mode by pressing the TIMER
ON/OFF, LF (+), and LR (+) keys at the same
time. The TIMER window will flash the words
TECH MODE.
4. Begin the calibration procedure by pressing the
TIMER ON/OFF, LF (+), and RF (+) keys at
the same time. The TIMER window will flash
CAL and the LF surface element power win-
dow will flash the U symbol.
