face below the Advantium rise into the base hood
of the oven, the Base Hood TCO (see page 53)
senses this temperature. When the temperature
of the TCO reaches 133°F/56°C, the TCO trips
(contact close) and signal the Smart Board to
turn on the vent fan. When the temperature of
the TCO cools to 104°F/40°F, the TCO will open
and signal the Smart Board to turn off the vent
fan.
The important item to note is that this feature is
not controllable by the consumer, but is instead
fully automatic.
Relay Board Assem-
bly Removal
The relay board can
be replaced from
the front of the oven.
This board receives
control inputs from
the Smar t Board,
which in turn acti-
vates and deacti-
vates relays on the
relay board (turning
the halogen lamps on
and off as required).
To replace the board, re-
move the screw shown in
the illustration to the right.
Once this screw is remove, gen-
tly lift upward on the board, in order to release
the mounting tab on the back of the plastic
bracket. This tab secures the relay board as-
sembly (relay board and plastic mounting
bracket).

ADDENDUM
LAST MINUTE ADDITIONS TO THE MANUAL
The items included in this addendum were added
at the last minute, just prior to the printing of this
service guide. Please read each of these items
carefully and note their reference to other sec-
tions and topics within the service guide.
Voltage & Thermal Compensation
Pages 25-27 describe voltage and thermal com-
pensation. It is important to note that voltage
and thermal compensation only occur during
SPEEDCOOK
operation (preselect
menu item). In other words, when
cooking with
MANUAL COOK
, ther-
mal and voltage compensation
do not occur. When using
SPEEDCOOK
, you are selecting
preselected items from a menu.
These items require compensa-
tion in order for accurate and con-
sistent cooking results.
Thermistor, Oven Cavity
The oven cavity thermistor has a
negative temperature coefficient. In
other words, as the temperature of the
thermistor probe (located inside the
oven cavity - see page 26) increases,
the resistance of the thermistor de-
creases. The resistance of the ther-
mistor changes quickly with small changes in tem-
perature. In fact, you can squeeze the thermistor
and see the resistance change fairly quickly.
At room temperature, the thermistor should read
approximately 150K-220K ohms.
Vent Fan Automatically Activates
The vent fan can automatically come on without
being select by the consumer. This feature is
controlled by the Smart Board and Base Hood
TCO. As heat and fumes from the cooking sur-
