Glass Touch Models ONLY

Touch Control
Check the touch control panel for delamination to
make sure the touch board is not separating from
the glass. Next, check to make sure the resis-
tance is infinitely high between ALL pins. Any
impedance implies a faulty touch control.
Attention: The new glass touch models maintain
a constant exchange of information between the
touch control and the main board through a ribbon
cable. These signals have an upper and lower
value limit for the ERC to interpret them correctly.
Any interruption to this connection will break the
continuity, and possibly push the parameters
outside the limits. This will issue an F0 fault code,
and cause the controls to not function.
When any service is performed that requires
moving, or removing, the touch control or
main board, the glass touch parameters must
be set.
Setting Touch Control Parameters
Note: After installing the control, the glass touch
parameters must be set. If they are not set, the
control will not operate.
To set these parameters on a new part
installation:
1) Reassemble the control panel and return the
oven to its normal installation.
2) Reset circuit breaker to apply power to the
oven. The control will briefly display all LED
segments, briefly display "LOC REF," then
display all segments again for 30 seconds, and
finally display "LOC REF" continuously. After
this sequence is completed, proceed to step 3.
3) For digital keypads, press the "6" and "8" keys
simultaneously.
For slew keypads, press the "Hour Down" and
"Minute Up" keys simultaneously.
4) The control will then display the time of day
and operate.

5) If steps 2 through 4 do not occur as described,
repeat the process.
6) Check the control for operation, especially the
"Clear/Off" and/or "Cancel" keys.
Note: If for any reason the control panel is
opened, or if the new control still does not
operate as described above, complete the
following steps:
1) Press the "Bake" and "Broil" keys
simultaneously.
2) For digital keypads, press the "9" and "0" keys
simultaneously for 5 seconds.
For slew keypads, press the "Hour Down" and
"Minute Down" keys simultaneously for
5 seconds.
3) Wait approximately 20 seconds after the time
of day is displayed.
4) For digital keypads, press the "1" and "5" keys
simultaneously.
For slew keypads, press the "Temp Up" and
"Minute Up" keys simultaneously.
5) The control will briefly go blank,briefly display
all LED segments, briefly display "LOC REF,"
then display all segments for 30 seconds, and
finally display "LOC REF."
6) For digital keypads, press the "6" and "8" keys
simultaneously.
For slew keypads, press the "Hour Down" and
"Minute Up" keys simultaneously.
7) The control will then display the time of day
and operate.
8) Check the control for operation, especially the
"Clear/Off" and/or "Cancel" keys.
