ELECTRONIC OVEN CONTROL (FAULT CODES)
FAILURE MODES
F0 - ALARM (EEPROM OPTION)
This EEPROM selectable option enables the control to recognize a shorted key within approximately
32 seconds. This option has priority over shorted watchdog failure alarm F1.
F1 - ALARM
A failure is detected in the element relay watchdog protection circuits and will activate a "CANCEL"
feature. "F1" will be displayed in the time digits and the alarm will sound until the cancel key for the
oven is pressed or another function is selected.
F2 - ALARM
Occurs when cavity temperature exceeds the clean runaway temp in the clean mode or the cooking
runaway temp in a non-clean condition and will activate a "CANCEL" feature. "F2" will be displayed in
the digits for the affected cavity, and the alarm will sound until the CANCEL key for the oven is pressed
or another function is selected. This failure may be overridden by the F3 or F4 alarm.
F3- ALARM
Occurs when there is a short circuit in the oven temperature sensor for 16 temperature conversions in
a row and will activate a "CANCEL" feature. "F3" will be displayed in the digits for the affected oven
cavity, and the alarm will sound until the CANCEL key for the oven is pressed. The alarm will return in
16 seconds if the failure is still present.
F4 - ALARM
An open circuit in the oven temperature sensor for 16 temperature conversions in a row will activate a
"CANCEL" feature. "F4" will be displayed in the temp digits for the affected cavity, and the alarm will
sound until the CANCEL key for the affected oven is pressed. If the failure is present after cancel is
pressed, the alarm will not be reactivated unless a baking or cleaning function is attempted. The
opposite oven is unaffected with this alarm.
F6 - ALARM
A failure is detected in the EEPROM checksum comparison. This indicates the EEPROM checksum
and the calculated checksum are not the same. Only time of day and timer operation will be allowed in
the control.
F-7 ALARM
A failure detected in the clean lock/phase circuitry for 16 seconds in a row will activate a "CANCEL"
feature. "F7" will be displayed in the temp digits of the affected oven and the alarm will sound until
CANCEL for the affected oven is pressed or another function is selected. This test will be performed
constantly.
F-8 ALARM
Occurs when the door lock runs for 2 minutes without seeing either the lock or phase switch change
positions.
