OPERATIONS TO CHECK
REMAINING FUNCTIONALITIES
1. Latch mechanism and cooling fan high speed. Press
[Cooking Mode] key then turn the knob CW until the CLEAN
mode is found. Press [Start] key once and again when the
writing REMOVE RACKS appears. The control runs the latch
until the door is locked. Just a while before the lock symbol is
displayed, the cooling fan switches to high speed. Check that
the door is actually fully locked. To unlock the door, press
[Cancel] key and wait for the lock symbol on the display
disappear. Now the door has to be fully unlocked.
2. Door switches and cavity lights. Open the door, if the cavity
lights turn on it means that the control has detected a change.
Close the door, the lights must turn off. If the lights don't turn
on, try to press the [Light] key and be sure to hear a key
pressed tone. If the lights still remain off, they are probably
broken. If no tone is heard, then the [Light] key is not
working.
3. Keyboard and thermal cavities. Select the lower cavity by
pressing [Upper/Lower] key, until the box is displayed in the
lower oven position (only for double oven). Press [Cooking
Mode] key, BAKE will flash. Turn the knob CW until BAKE
mode is found again. If the cavity is set as thermal, only
BAKE, BROIL CLEAN and WARMING must be available.
Press [Temperature] key and see that the displayed
temperature is flashing. Press [Start] to run the cooking mode
then [Lower Cancel] (simply [Cancel] for a single oven) to
stop it.
