OVEN MODEL CONFIGURATION, TEST PROCEDURE & ERROR CODES
OVEN MODEL CONFIGURATION
Resistors R49, R51 and R52 on the display board must be configured properly, according to the oven model,
prior to installing the display board in the oven.
• Always cut R49 in single ovens.
• Always cut R52 in 27” ovens.
• Always cut R51 in ovens with a thermal cavity.
The test procedure must be completed to acknowledge and confirm this selection. If the control has never
been configured before, the display shows “F11 Err” at power-up. Once a configuration has been accepted,
the failure disappears.
At every power-up, the control runs a latch auto-test cycle. The lock icon flashes while the latch is moving.
Hold the [STOP] and [SET CLOCK] buttons at the same time for about 3 seconds. Check that all the display
elements and the buzzer turn on for about 5 seconds.
Press [+] to enter test mode, then press [+] to proceed to the next step or [-] to go back to the previous one.
Check the display board software version (d36 or d38).
Check the main power board software version (P32 or P34).
Check the lower oven power board software version (P32 or P34 - double ovens only).
Check whether the oven model has been correctly detected. Otherwise, check whether the configuration
resistors have been properly set as described earlier.

OVEN MODEL CONFIGURATION, TEST PROCEDURE & ERROR CODES
Verify that the meat probe option is off.
NOTE: In case of a thermal cavity, some steps are not necessary and are automatically skipped.
STEP 01: Check the oven lights.
STEP 02: Check the cooling fan.
STEP 03: Check the working fan.
STEP 04: Check the double line break (DLB) relay. The bottom element relay is closed, the DLB relay stays
open. The heating element must not energize, otherwise it means that the DLB relay has shorted.
STEP 05: Check the bottom heating element (3000W). The DLB relay is now closed.
STEP 06: Check the top heating element (3500W).
STEP 07: Check the ring heating element (2500W). The working fan is also running.
STEP 08: Check the additional heating element (1000W).
STEP 09: Check the cooking mode selector. Within 1 sec., “C00” is automatically displayed. Turn the knob
clockwise and check that the values match the ones in the following table:
Once back to the “off” position, the control automatically comes back to the S09 step indication.
STEP 10: Check the temperature selector. Within 1 sec., “dEf” (default) is automatically displayed in the
“preset” position. Turn the knob clockwise and verify that:
1. The temperature changes between 170°F and 550°F.
2. In “clean” position, the display must show “Cln”.
Once back to the “preset” position, the control automatically comes back to the S10 step indication.
STEP 11: Press [SET CLOCK] and check the temperature measured by the sensor inside the cavity.

STEP 12: Press [SET CLOCK] to go back to the S11 indication.
Single Oven: Once “End” has been displayed, hold the [COOK TIME] and [TIMER] buttons at the same time
to quit manual test and go back to the normal oven operating mode. Go to section “FURTHER
VERIFICATIONS IN THE NORMAL OVEN OPERATING MODE” on the following page.
Double Oven:Repeat the same steps for the lower oven. In case of a thermal cavity, some steps are not
necessary and are automatically skipped.
STEP 13: Check the oven lights.
STEP 14: Check the cooling fan.
STEP 15: Check the working fan.
STEP 16: Check the double line break (DLB) relay. The bottom element relay is closed, the DLB relay stays
open. The heating element must not energize, otherwise it means that the DLB relay has shorted.
STEP 17: Check the bottom heating element (3000W). The DLB relay is now closed.
STEP 18: Check the top heating element (3500W).
STEP 19: Check the ring heating element (2500W). The working fan is also running.
STEP 20: Check the additional heating element (1000W).
STEP 21: Check the cooking mode selector. Within 1 sec., “C00” is automatically displayed. Turn the knob
clockwise and check that the values match the ones in the following table:
Once back to the “off” position, the control automatically comes back to the S21 step indication.
STEP 22: Check the temperature selector. Within 1 sec., “dEf” (default) is automatically displayed in the
“preset” position. Turn the knob clockwise and verify that:
1. The temperature changes between 170°F and 550°F.
2. In “clean” position, the display must show “Cln”.
Once back to the “preset” position, the control automatically comes back to the S22 step indication.
STEP 23: Press [SET CLOCK] and check the temperature measured by the sensor inside the cavity. Press
[SET CLOCK] to go back to the S23 indication.
Once “End” has been displayed, hold the [COOK TIME] and [TIMER] buttons at the same time to quit manual
test and go back to the normal oven operating mode.

FURTHER VERIFICATIONS IN THE NORMAL OVEN OPERATING MODE
Self-Clean:
1. Open the door and verify that the oven lights switch on. Close the door and verify that the lights switch
off (door microswitch verification).
2. Turn the cooking mode selector to “clean” position. Self-clean must not start.
3. Start self-clean in the main cavity by also turning the temperature knob to the “clean” position (two
steps on).
4. Check whether the door is actually locked. (As soon as the lock icon stops flashing and remains
steadily on, the door is locked.)
5. Stop self-clean by turning the cooking mode selector to the “off” position (one step off).
6. Check whether the door is actually unlocked. (As soon as the lock icon stops flashing and turns off, the
door is unlocked.)
7. Turn the temperature selector to the “preset” position.
8. FOR DOUBLE OVENS ONLY: Repeat the same sequence described above for the lower oven.
NOTE: The lock icon flashes when the latch is in motion.
Remaining Buttons Functionality:
1. Press the [LIGHT] button and verify that the oven lights switch on. Press it again to switch the lights off.
2. Press the button:
a. [UPPER/LOWER] (in the case of a double oven) and verify that the cavity selection box turns on
and switches up and down every time the button is pressed.
b. [LOCK] (in the case of a single oven) and verify that the buzzer sounds.
3. Press the [-] button and verify that the buzzer sounds.
When a failure occurs, the display shows “F07 Err”.
To reset the failure, the cause must be removed and the cooking mode selector must be turned to the “off”
position.
