How to Speedcook
To Select a Speedcook Program:
1. Press the SPEEDCOOK button.
2. Turn the selector dial to select the type of food you want.
Press the dial to enter it.
3. Turn the dial to select the specific food. Press the dial to
enter it.
4. Turn the dial to select the amount, size, and/or doneness (if
required, the oven will prompt you). Press the dial after
each selection.
5. Once the display shows “ADJUST TIME OR START,” press
either the selector dial or START/PAUSE button to start
cooking.
If the door is opened during cooking, the oven stops and
“PAUSE” appears in the display. Close the door and press
START/PAUSE to resume cooking. At any time during the
cooking, you can turn the selector dial to change the cooking
time. You can also change power levels.
Advantium uses power from high-intensity halogen
lamps, as well as microwave energy, to cook foods
evenly and quickly (average of one-fourth the time
of a conventional oven) to seal in moisture and
flavor.
Example: Upper element set at 80% (U=08),
lower element set at 50% (L=05), and microwave
set at 30% (M=03).
Select UPPER POWER:
5:00 U=08 L=05 M=03
Power levels are selected with the selector dial
and can be adjusted before cooking or during
cooking. When using preset menu foods, the
power levels are already selected for you.
However, power levels can be adjusted when
cooking both preset menu food and when manual
cooking.
Power levels are adjusted independently for the
upper halogen lamps (pair), lower halogen lamp
(single), and microwave energy. When selecting
an upper halogen lamp power level, the power
level can only be selected for the pair. You can not
select power levels for the upper rear and upper
front independently.
Power levels of 0 to 10 can be selected for the
upper halogen lamps (pair), lower halogen lamp,
and microwave energy. The power levels control
the percentage of ON time for the upper halogen
lamp pair, the lower halogen lamp, and microwave
high voltage circuit.
The programming on the smart board which
controls the upper and lower halogen lamps, as
well as the high voltage/magnetron circuits,
operates on a duty cycle of 32 seconds. This
means the power level you select for each
component controls the percentage of ON time
during each 32-second period of time.
In the following example, the upper halogen lamps
would cycle for 80% of each 32-second period, the
lower would cycle at 50% of each 32-second
period, and the microwave high voltage circuit
would be energized for 30% of each 32-second
period.

distributed to all portions of the food. Select a
higher setting to shorten cooking time for dense or
heavy foods (example: casseroles, whole
chicken). Select a lower setting for delicate foods
(example: cakes, breads, souffles) or foods

Voltage Compensation
Note: Voltage compensation only occurs during
speedcook operation (preselect menu item). In
other words, when cooking with manual cook,
voltage compensation does not occur. When using
speedcook, you are selecting preselected items
from a menu. These items require compensation
for accurate and consistent cooking results.
Voltage fluctuations in the power lines can cause

automatically measures line voltage at the start of
each speedcooking selection and adjusts thecooking time to achieve consistent quality
results.
Line voltage is monitored by the voltage

The optimal line voltage, where no voltage
compensation occurs, is 120 VAC. Above
120 VAC, time is subtracted from the recipe.
Below 120 VAC, time is added to the recipe. The
amount of voltage compensation required is
dependent upon the incoming voltage at the start
of the cooking cycle, and the particular
Voltage compensation only occurs during
speedcook operation and only occurs once during
the cooking cycle (at initial start of speedcook
operation).
Upper Halogen Lamp Balance
As stated previously, the upper halogen lamps
operate together at the same power level.
However, in order to provide even (balanced)
cooking performance, the upper rear halogen
lamp will always cycle at 85% of the upper front
halogen lamp. In other words, if the upper halogen
lamps are set at power level 10 (U=10), you would
expect both elements to operate at 100% of each
32-second duty cycle. Instead, the upper rear
halogen will cycle at 85% of power level 10, or
– 18 –
85% of 32 seconds. The upper rear halogen lamp
will cycle off just prior to the upper front.
Thermal Compensation
Note: Thermal compensation only occurs during
speedcook operation (preselect menu item). In
other words, when cooking with manual cook,
thermal compensation does not occur. When
using speedcook, you are selecting preselected
items from a menu. These items require
compensation for accurate and consistent cooking
results.
When cooking several food items consecutively,
the temperature in the oven’s interior can become
very hot. The Advantium speedcooking program
(smart board) automatically compensates for the
increased temperature by adjusting the cooking
power levels of the upper and/or lower halogen
lamps. This innovative technology gives you ovenquality food with consistent results.
resistance changes rapidly with small changes in
temperature. In fact, you can squeeze the
thermistor and see the resistance change fairly
quickly. At room temperature, the thermistor
should read approximately 200K to 250K ohms.
Thermal compensation can affect the upper
halogen lamps power level, the lower halogen
lamp power level, or both the upper and lower
halogen power levels simultaneously. Ther mal
compensation can lower the upper halogen pair
by 1, 2, or 3 power levels. The lower halogen lamp
can also be reduced by 1, 2, or 3 power levels, but
nev er independently of the top halogen lamp pair.
In other words, thermal compensation on the
lower lamp will never be greater than the
compensation occurring on the top lamps. It is
possible, however, to have thermal compensation
occurring on the upper halogen lamp pair, but not
on the lower lamp.
Neither the upper halogen lamp pair nor the lower
halogen lamp can be compensated below power
levels of 2. In other words, if a power level of 3 is
selected for either the upper halogen pair or the
lower halogen lamp, then thermal compensation
can only reduce the power level by a maximum of
1 power level.
GEA00439
Located inside of the oven cavity (upper right rear)
is a thermistor. At the start of each new
speedcooking operation (just prior to voltage
compensation occurring), the cavity thermistor
reads the oven cavity temperature. Depending
upon the oven cavity temperature and the amount
of cooking time selected, the smart board will
adjust the power level of the upper and/or the
lower halogen lamps to compensate for the
additional heat that may already exist in the oven
cavity (if previous cooking occurred).

The oven cavity ther mistor has a negative
temperature coefficient. In other words, as the
temperature of the thermistor probe increases, the
resistance of the thermistor decreases. This
– 19 –
Thermal compensation only occurs when oven
cavity temperatures are higher than normal from
the previous cooking operation. When thermal
compensation is required, it will occur immediately
upon the start of a new speedcook operation (just
prior to voltage compensation occurring) and
there will be no indication in the display that
thermal compensation has occurred. The amount
of thermal compensation (1, 2, or 3 power levels)
depends upon the temperature of the oven cavity
at the start of the speedcook operation and the
amount of time selected.
When thermal compensation occurs, it is not
possible to see the adjusted power levels in the
display. If you were to press the power level pad
during a speedcook operation in which thermal
compensation occurred, you would not see the
adjusted power levels in the display. In fact, what
you would see is the original power level setting.
However, you can visually see compensation
occurring by carefully observing the cycling of the
halogen lamps.
WARNING: When viewing the halogen lamps, do
not stare directly into the face of the door window.
View the oven interior from a distance far enough
not to cause eye strain.

Thermal Compensation Test
To better understand this operation, you can
perform the following test (only if the oven cavity is
at room temperature). Remove the pan from the
oven so you can see both the upper and lower
halogen lamps. Select “Speedcook, Meats,
Hamburger, 1/2 inch thick, 1-2 patties.” The
following will show in the display:
ADJUST TIME or START
3:00 U=10 L=10 M=10
OVEN LOCKED SELECTMUTE TIMER
GEA00426
Notice that the display shows power levels of 10
for each cooking component. During this test, you
will be operating the oven with no load. For this
reason, it will be necessary to adjust themicrowave power level to zero (M=00). To do
this, press the power level button on the control
panel. Leave the upper and lower power levels at
10 (U=10, L=10), and adjust the microwave to
zero (M=00).
Press START to run
3:00 U=10 L=10 M=00
OVEN LOCKED SELECTMUTE TIMER
NOTE: Set Microwave to Zero (M=00)
GEA00427
What is important to note is that while the power
levels have been reduced (thermal compensation),
the power levels which will show in the display (if
you touch the power level pad while speedcooking
operation is occurring) will be the original power
levels (U=10, L=10, and M=00).
From a consumer’s point of view, if the consumer
were to cook two hamburger patties, and then
immediately cook two more patties, they could
notice the halogen lamps cycling differently with
the same selection used each time. This is
perfectly normal when thermal compensation
occurs. The consumer’s Owner’s Manual states
the following:
Page 21 - Lights
“The halogen lights will dim and cycle on and off
during a speedcook cycle, sometimes even at full
power levels. This is normal. The oven senses the
heat level and adjusts automatically.”
Page 38 - Troubleshooting, Lights
“Light during a speedcook cycle dims and cycles
on and off, even at full power levels. This is normal.
Power level has been automatically reduced
because the oven is hot. The oven senses the
heat level and adjusts automatically.”
Thermal Protection
Start the speedcook operation and carefully notice
the cycling of the halogen lamps. At power levels
of 10, both the upper halogen lamp pair and the
lower halogen lamp should be on 100% of the
time. However, remember that the upper rear
halogen lamp always cycles at 85% of the upper
halogen power level setting, so you will be able to
see the upper rear halogen lamp cycle off briefly
(see “UPPER HALOGEN LAMP BALANCE” for
additional information).
With approximately 1 minute remaining, the oven
will stop and you will be instructed to turn over the
food. Briefly open the door and close it, and then
touch START to resume the remainder of the
cooking time. At the end of the cooking cycle,
repeat the steps above using the same
hamburger selection (remember to once againset the microwave power level to zero (M=00)).
Once again pay attention to the halogen lamp
cycling. Since the oven is now hot, you should be
able to visually see thermal compensation
occurring. You will notice that both the upper and
lower halogen lamp power levels have been
decreased by some amount.
If oven cavity temperatures reach somewhere in
the range of 500°F to 600°F, or if a speedcooking
selection is chosen which exceeds 12 minutes of
cooking at halogen lamp power levels (upper and
lower) greater than 7, all power levels (upper,
lower, and microwave) will be reduced to 7 for the
remainder of the speedcooking selection. This
system allows for safe exterior operating
temperatures.
In the unlikely event that ther mal protection is
required, the consumer will not notice any change
in the display readout (no power level change
indication); however, they may notice that the
halogen lamps are cycling differently than
expected, due to the change in power levels.
GEA00428

As was the case with thermal compensation, the
control is provided by the thermistor and smart
board, with the thermistor sensing the oven cavity
temperature and the smart board providing the
proper responses to lower all power levels to 7.

Thermal Safety
In the unlikely event that internal oven cavity
temperatures exceed 600°F, speedcooking
operation will be terminated.
The oven cavity thermistor is constantly sensing
oven cavity temperatures and providing input to
the smart board. When the smart board
determines that over 600°F has been reached, it
will terminate speedcooking operation and return
the oven display to its normal OFF position (with
time-of-day clock showing in the display). When
the unit cools, it will return to normal operation.

During microwave oven cooking, the damper door
is fully open, allowing air to travel through and
around the magnetron tube into the oven cavity.

GEA00431
During speedcooking operation (recipe or manual
speedcook), the metal damper door rotates into
the damper chamber, closing off air flow from the
magnetron blower into the oven cavity. In doing so,
heat from the oven interior is contained in the
oven cavity.
Damper Door Assembly
The damper door assembly has a metal semiround door, which rotates by control of a damper
motor, to open and close off air from the damper
chamber to the oven cavity. The thermal fuse and
door sensing switch mount to the damper door
assembly.
Damper Door Switch
The damper door sensing switch is mounted to
the damper duct. The switch monitors the metal
door position and provides this information to the
smart board (“Metal damper door open” or “Metal
damper door closed”), which controls the direction
and operation of the damper door motor. If the
damper door sensing switch shorts (or opens), the
damper motor will continually cycle the damper
door open and closed until one complete switch
cycle is detected.

•Speedcooking - At the start of speedcooking
operation, the damper door will close, sealing
off the damper duct from the oven cavity. The
damper door will remain in the closed position
during the entire speedcook operation,
depressing the damper door sensing switch.
•Microwave oven cooking - At the start of
microwave cooking, the damper door will cycle
one complete revolution (completely close and
then reopen) and stop in the open position
(damper door sensing switch not depressed).
The oven cavity lamps will not illuminate
during microwave operation.
Oven Cavity Lamps
The oven cavity lamps are located at the upper
rear of the oven cavity and illuminate only when
the oven door is opened. During microwave oven
cooking, the oven interior can be illuminated by
pressing the MICROWAVE OVEN LIGHT pad on
the front panel. The lights will come ON and will
remain ON until the end of the cooking cycle. In
the event that it becomes necessary to change the
lamps, it will be necessary to remove the oven
from its installation.
Thermal Fuse
The thermal fuse is mounted to the top of the
damper duct over a small rectangular hole in the
duct. This hole allows the thermal fuse to sense
temperatures inside the duct cavity. The fuse is
secured to the damper duct with a small screw
and retainer. In the event that it becomes
necessary to change this fuse, it will be necessary
to remove the oven from its installation (see page
32).

the end of speedcooking, the exhaust fan will
continue to run for 1 minute (30 seconds on HIGH
and 30 seconds on LOW), and the display will
read “OVEN IS COOLING.” The fan will
automatically shut off when the internal par ts of
the oven have cooled.
Upper and Lower Halogen Blowers
The upper and lower halogen blowers only run
during speedcook operations (speedcook recipe
or manual speedcook selections). Both motors
pull in fresh air from outside the unit and direct the
air across the halogen lamps.
Upper Halogen Blower
As you will note from the illustration on the
following page, the upper halogen blower pulls air
in from the upper grille area. The air is then
directed (blown) across the upper halogen lamp
pair and exhausted back into the room through the
lower grille area. The hot air directed across the
upper halogen lamp pair is not controlled or
directed by the exhaust motor.
Lower Halogen Blower
The lower halogen blower draws room air in
through the upper grille area. The air is pulled
down into the lower halogen blower and directed
(blown) across the lower halogen lamp. The air is
then exhausted through the lower grille area.
Magnetron Blower Assembly
During microwave operation, room air is drawn in
through the upper grille area and into the
magnetron blower area. The magnetron fan blows
the cool air through and around the magnetron
tube. The air then passes through the damper
door assembly (damper door is open during
microwave operation) into the oven cavity.

An important part of diagnosing any consumer
cooking concern is listening carefully to the
consumer describe the problem. Equally important
is asking the consumer the right questions. The
following diagnostic information is intended as a
guide for you to follow when addressing cooking
concerns.
Food Items Appear to be Undercooked
Foods which appear to be undercooked or
partially cooked can be the result of any one of the
following items. The possible causes listed below
are sorted from most likely to least likely, with item
#1 being the first item that you should check.
1. Is the consumer selecting the correct type of
cooking (microwave vs. speedcook), and/or is
the consumer using the correct time and
power levels for the type, size, and quantity of
food being cooked (see the Advantium cooking
guide)?
2. Is the consumer using the correct cookware
for the type of food being cooked (see pages
5 and 17 of the Owner’s Manual, and pages 5
and 6 of the Advantium cookbook)?
3. Is the consumer arranging the food properly
on the metal cooking trays (see the Advantium
cooking guide and page 7 of the cookbook)?
4. Is the turntable operating properly so that
microwave energy and halogen heat are being
evenly distributed to the food?
5. Inspect the upper and lower halogen lamp
covers to ensure that they are free of grease
and food spatterings. Build-ups of grease and
food spatterings can cause a decrease in
cooking performance.
6. Confirm proper line voltage to the unit (check
voltage under full load).
7. Confirm that voltage compensation is
operating properly (see page 18 of this service
guide for details and diagnostic information).
8. Confirm that the upper and lower halogen
lamps are operating (illuminating).
9. Check upper and lower halogen lamp
operation at power level 10 and again at power
level 5 to be sure that lamps are cycling
properly. At this point, you must have a
thorough understanding of power level
operation, upper halogen lamp balance
operation, and thermal compensation (see
pages 17-21 of this service guide for detailed
information).
10. Perform a microwave performance test (page
44) to confirm that microwave energy output
(HV/magnetron circuit) is operating to
specification.
11. Are all fan motors operating properly (page 23
of this service guide)? During speedcook
operation, all fan motors must operate
(exhaust fan, upper halogen lamp blower,
lower halogen lamp blower, and magnetron
blower). Improper airflow can cause the
halogen lamps or magnetron tube to cycle on
the thermal cut-outs (T.C.O.s).
Food Items Appear to be Overcooked or Burned
Foods which appear to be overcooked or burned
can be the result of any one of the following items.
The possible causes listed below are sorted from
most likely to least likely, with item #1 being the
first item that you should check.
1. Is the consumer selecting the correct type of
cooking (microwave vs. speedcook), and/or is
the consumer using the correct time and
power levels for the type, size, and quantity of
food being cooked (see the Advantium
cooking guide)?
2. Is the consumer using the correct cookware
for the type of food being cooked (see pages
5 and 17 of the Owner’s Manual, and pages 5
and 6 of the Advantium cookbook)?
3. Is the consumer arranging the food properly
on the metal cooking trays (see the Advantium
cooking guide and page 7 of the cookbook)?
4. Is the turntable operating properly so that
microwave energy and halogen heat are being
evenly distributed to the food?
5. Confirm proper line voltage to the unit (check
voltage under full load).
6. Confirm that voltage compensation is
operating properly (see page 18 of this service
guide for details and diagnostic information).
– 42 –
7. Check upper and lower halogen lamp
operation at power level 10 and again at
power level 5 to be sure that lamps are cycling
properly. At this point, you must have a
thorough understanding of power level
operation, upper halogen lamp balance
operation, and thermal compensation (see
pages 17-21 of this service guide for detailed
information).
8. Confirm that thermal compensation is
operating properly by following the thermal
compensation test (see page 21 of this
service guide).
Diagnosing a “Dead” Unit
A “dead” unit is better defined as a unit that
appears to have no power to it (no clock display,oven cavity lamp, or key panel responses). The
following components and associated wiring
should be checked in the below order when
diagnosing a “dead” unit.

3. If you read approximately 22 ohms from L1 to
NEUTRAL, suspect a defective smart board,
loose wiring connection, or open secondary
winding of the low voltage transfor mer.
1. At the power source, use your volt/ohmmeter
and check the resistance from L1 to
NEUTRAL. The resistance should be
approximately 22.0 ohms. Note: The
resistance reading that you just made is
shown in the schematic diagram at the upper
right corner of this page (low voltage
transformer primary resistance).
GEA00517
2. If you do not read continuity from L1 to
NEUTRAL, suspect the following:
• Open fuse
• Open cavity T.C.O.
• Low voltage transformer (open primary
winding)
• Open magnetron tube T.C.O.
• Open thermal fuse
• Defective smart board
Also, check all associated wiring and wiring
connections.

Microwave Performance Test
This test will verify that the microwave oven high
voltage and magnetron circuits are operating to
performance specifications.
1. Using only a WB64XO073 beaker, place a
standard test load of 1 liter (1000 ml) of water
in the beaker. Measure and record the water
temperature prior to making the test. The
water temperature should be between 59°F
and 75°F.
The humidity sensor can be tested from the front
control panel area using the following diagnostic
procedure:
1. Disconnect the humidity sensor connector
from the smart board (CN4, 3 pin - red
connector plug located at the top of the smart
board).
2. Using an ohmmeter, set the scale to Rx1000,
and confirm the following approximate
resistance readings:
2. Place the beaker in the center of the oven on
the white ceramic microwave cooking tray.
3. Close the oven door. At the front control panel,
select “Microwave, Time Cook, 2:03 Minutes,
Power Level 10.” Press START to begin
microwave cooking.
Select COOK TIME
2:03 M=10
OVEN LOCKED SELECTMUTE TIMER
GEA00437
4. At the end of the cooking cycle, remove the
beaker of water, and measure and record the
temperature.
5. The minimum difference between the initial
and ending temperatures should be 32°F at
240 volts.
If the water temperature rose but did not reach the
32°F minimum, suspect a problem with the line
voltage (test under full load) or magnetron tube/
high voltage circuit.
If the water temperature did not rise at all, suspect
a problem in the high voltage circuit.

Microwave Leakage Test
Caution: This test should not be performed
during a speedcook operation. This test should
only be performed during microwave-only
operation.
To perform a microwave leakage test:
1. Place 275 ml of water in a 600 ml beaker
(WB64X5010).
2. Place the beaker in the center of the white
ceramic tray.
3. Set the leakage meter to the 2450 MHz scale.
Humidity Sensor Test
Note: Oven should be plugged in at least 5
minutes before test.
• Room temperature should not exceed 95°F.
• Be sure the exterior of the cooking container
and the interior of the oven are dry.
• No sensor cooking is available during 5 minutes
immediately after speedcook.
4. Program the microwave for 5 minutes (power
level 10) and press START.
5. Hold the probe perpendicular to the surface
being tested and scan surfaces at a rate of
one inch/sec. Scan the following areas:
• Entire perimeter of door and control panel
• Viewing surface of door window
• Exhaust vents
– 44 –
Key Panel Test
If necessary, the key panel pads can be verified by
a continuity test. For ease of handling, the key
panel should be removed and placed on a flat
protected surface. Check continuity between the
connections at the end of the ribbon (use high
ohm scale).
GEA00340
Note: Maximum allowab le leakage should not
exceed 4 MW/CM2, which is used to allow for
measurement and meter accuracy.
6. Leakage should not exceed 4 MW/CM
2
.
7. Inform the manufacturer of any oven found to
have emissions in excess of 5 MW/CM
2
. Try to
determine the cause of excessive leakage and
make repairs to bring the unit into compliance
at no cost to owner. Instruct the owner not to
use the oven until it has been brought into
compliance.
8. Record the data on your service invoice and/
or microwave leakage report.
Performance Test for Halogen Lamps
Caution: When performing this test, use only a
glass beaker. Plastic beakers will melt!
Note: This test should be run when the oven is
cool.
1. Place 1000 ml of water in a 1000 ml glass
beaker.
2. Record the initial water temperature.
GEA00346
To perform the test, press the appropriate pad on
the front panel. While pressing the pad, check for
continuity between the appropriate pins. For
example, while pressing the SELECTOR DIAL,
you should read continuity between pins 1 and 8.
Fault Codes
The smart board monitors various operations and
can detect certain failure modes. In the event of
specific failures, cooking will be terminated, a 4beep signal will be heard, and a fault code will be
displayed.
3. Place the beaker in the center of the black
metal tray.
4. Program oven at U=10, L=10, and M=0 for 2.5
minutes and press START.
5. Record the ending water temperature.
The minimum difference between the initial and
ending temperature should be 15°F at 240 volts.
Also, a continuity test can be taken on the upper
halogen lamps by disconnecting the blue and
white connectors located near the upper blower
motor. Check the resistance with an ohmmeter.
Pressing the CLEAR pad will remove the fault
code display unless the failure is a shorted key
panel switch. Detection of a failed sensor will have
no effect on features that do not use that sensor.
F4 (open or shorted humidity sensor) and F6
(high cavity temperature during microwave
cooking) codes apply only to microwave
cooking.
– 45 –
The chart below indicates failure modes which can
be detected and displayed:
Sometimes fault codes will appear with no
apparent cause. These codes and their
symptoms include:
•F1 - If the food is a large cold load that must
cook over 5 minutes, the temperature of the
cavity may not rise fast enough to change the
thermistor resistance very much. The control
believes that the thermistor is not responding
because it is open, and thus displays the F1
code. This can be cleared at the end of the
cycle and cooking will continue.
•F4 - If there is an electrical surge or excessive
line “noise” within the home, it could cause F4
to display on the control. The sensor will
remain inoperable until the control is reset.
This can be done by removing power (turning
off the circuit) to the unit for 1 minute.
NOTE: Replacing the humidity sensor will not
cure this situation if it was due to electrical
“noise.”
•Interior oven lights stay on or off and donot respond to key commands - This is also
caused by electrical surge or excessive line
“noise.” Remove power (turn off the circuit) to
the unit for 1 minute. Replacing parts will not
solve the problem.
