Surface Element Replacement

Note: The surface element, pan sensor, and
temperature sensor are 

only  replaceable as an

assembly, which includes the sensor wire harness
and connector.

1.  Remove the glass and cooktop from the

countertop (see the procedure).

5.  When the TIMER window displays 

DISC and

the U symbol stops flashing in the LF surface
element power window, 

center  the aluminum

disk on the LF surface element.

6.  Press the PAN and LF (+) keys at the same

time.  The electronic control will perform the
calibration on the LF sensor and then proceed
to the next surface element.  The TIMER
window will flash 

CAL and the U symbol will

flash in the LR surface element power window.

7.  Repeat steps 5 and 6 for the LR, CR (if

present), RR, and RF surface elements.

8.  After the RF surface element has been cali-

brated, the timer window will display a PASS or
FAIL message for the entire calibration proce-
dure.  An 

F will be displayed in the surface

element power window of any sensor that fails
the process.  Acknowledge this message and
exit the calibration procedure by pressing the

PAN and RF (+) keys at the same time.

Note: If the calibration proceedure is interupted for
any reason, exit the calibration proceedure by
pressing the PAN and RF (+) keys at the same
time.

Note: Failure of the calibration procedure may
occur for several reasons. If the calibration proce-
dure fails, follow these steps:

•  Try calibrating the cooktop again, beginning with

step 1 from above.

•  Identify the sensor(s) that fails the calibration

procedure.

•  If multiple sensors fail the calibration procedure,

replace the logic board.

•  If only one sensor fails the calibration procedure,

replace the corresponding surface element.

Caution: Do not cut the wire ties from the wire

harness. Care 

must be taken to ensure that

only the sensor wires to the surface element
being replaced are cut.

Caution: Routing of the wires is extremely
critical. Care must be taken to ensure the wires
are routed exactly the way they were originally.

3.  Using diagonal cutters, snip 

both  the tempera-

ture sensor and the pan sensor wires and
remove them from the wire harness leading
from the logic board to the surface element.

Note: When installing the new surface element,
tie-wrap temperature sensor and pan sensor wires
to the existing wire harness. Do 

not  cut existing

wire harness. Do 

not cut existing tie wraps.

2.

  Disconnect the appropriate sensor connector

from the logic board by pulling 

upward  on the

connector. (Do 

not disconnect the connector by

pulling on the sensor wires.) Trace the sensor
wires back to the appropriate surface element,
making note of where and how the wires are
routed.
