Throubleshooting
SYMPTOM POSSIBLE CAUSE PROBABLE SOLUTION
The oven (all
decks) does not
start, oven deck
lights is off and
display (ED mo-
del) is completely
dark
The power to the oven has been disconnec-
ted
Control voltage for all phases on termi-
nal X100 on deck 1
Bottom decks internal circuit breaker F101
has tripped
Reset tripped breaker
1 or more burned out PCB board. A broken
PCB board is mostly recognized by a slightly
round top of the PCBs black transformer,
when not broken/short circuit it is flat.
Replace the broken PCB boards. Con-
trol voltage as the most common cause
to a broken PCB board is a faulty electri-
cal/voltage connection.
If equipped with automatic start/stop timer,
settings are incorrect or timer is broken
Set main switch to position 1, restart
oven. If oven starts see page 30-33 for
correct timer settings, restart with timer
again. If timer is broken replace timer.
1 oven deck does
not start, OFF
is visual in the
display
Only for ED model, automatic timer function
is activated (Auto LED is lid up green) next
to ON/OFF button on the decks display.
Press and hold the displays ON/OFF
button until the Auto LED is turned off,
then start the deck by pressing the ON/
OFF button
1 or 2 (per deck)
oven lights does
not work but oven
deck is heated
normal
1 or more oven lamp bulbs is broken Replace the broken lamp bulbs, see
page 21
PCB board lamp output terminal can be
broken.
Control voltage between terminals (for
ED models ”LA” on green contact to
PCB board), should be 200-250V, if not
replace PCB board.
If both lamps are out the lamp transformer
can be broken (it is important to use original
lamp bulbs)
Control voltage on ceramic terminal
prior lampsocket, voltage should be 10-
12V. If not replace lamp transformer.
Lampsocket is broken. (still no lights and
lamp -bulbs -PCB board -transformer have
been checked OK)
Replace lampsocket.
Oven temperature
drop too much or
recovery period is
too long
Top and/or Top Front heat zones settings are
too low
Increase Top and/or Top Front heat
zones, see page 26
The draft connected to the ovens ventillation
is too high
Reduce draft, see page 16
The power to the oven has been partly dis-
connected
Check external breakers/fuses and
check that there is power in all the inco-
ming phases
The ovens ventillation is closed when oven is
fully loaded
Open the ovens ventilation
A contactor has burned out or a contactor
output is broken
Check contactors all in- and outputs
(L1-L3 and T1-T3)
