DIAGNOSTIC MODE
Diagnostic mode allows the Service Technician to determine the cause of the failure. In diagnostic mode only
the last error code is displayed.
To initiate diagnostic mode, the unit must to be in the "LOCK" mode. Then, press and hold the universal
"OFF" keypad for 5 seconds. The cooktop controls will now enter into diagnostic Mode.
In diagnostics mode, zone LED bars will illuminate and display the last error code logged.
NOTE: If no errors were recorded, no LED's will be illuminated. Unit will beep and return to "OFF" mode.
NOTE: If the "OFF" keypad is not released after 7 seconds,
the diagnostic mode will be cancelled and the unit will return
to the "OFF" mode.
NOTE: If any other input signals are detected from the key-
pad, the unit will not enter diagnostic mode.
NOTE: When in diagnostic mode all heating units are off.
NOTE: The unit will exit diagnostic mode if no inputs are
detected from the keypad in 20 seconds.
NOTE: If the "OFF" keypad is pressed again anywhere with-
in the diagnostic program, the unit returns to the "LOCK"
mode of operation.
NOTE: There will be no audible signals during the diagnostic
mode.
INTERPRETING HEX DECIMAL CODE
The front zone bar light uses the first four LED's from the
right (LED 16) to left (LED 1) to display the HEX DECIMAL
code used to determine the error code. Each LED has a cor-
responding numeric value that needs to be added together to
determine the corresponding error code.
(See Figure 6)
When the sum of the corresponding numeric value of the illu-
minated LED totals 10 - 13, then a letter is assigned in placed
of that sum. Example: 10 = A; 11 = B; 12 = C; 13 = D.
NOTE: The troubleshooting guide list the corresponding illu-
minated LED's. (See Figure 7)
NOTE: Error code may appear in either display or both simul-
taneously.
