approximation of the laws of the Member States relating to electromagnetic compatibility at the time of manufacture. However, some equipment with sensitivity to signals below these limits may experience interference.
If your equipment experiences interference:
a
Increase the physical separation between this oven and the sensitive equipment.
a
If the sensitive device can be grounded, do so following accepted grounding practices.
a
If battery-powered microphones are being affected, ensure that the batteries are fully charged.
a
Keep sensitive equipment on separate electrical circuits if possible.
a
Route intercom wires, microphone wires, speaker cables, etc. away from the oven.

Date and Time Prompt
NOTE: The following information is applicable to
ovens equiped with a touch screen (see page 1).
The oven maintains a data log that contains
valuable information about the operation of the
oven, including faults, items cooked, and other
events. An accurate date and time are important
for the data log. If the oven loses the date and
time as a result of prolonged disconnection from
power, a prompt will alert the operator to set the
date and time. The prompt will only occur once.
If bypassed, the operator must update the date and
time from the Info Mode Settings screen (see page
16 for details).
Voltage Selection
For North America oven models, the oven will
detect 208 or 240 incoming voltage.
If incoming voltage for the store is different than
the factory-preset voltage, the operator will be
required to select either 208 or 240. The correct
voltage will be enlarged on the screen, identifying
which option to touch (see Figures 3 and 4 below).
Figure 3: Selecting Voltage

Menu Cook Mode
The oven is preprogrammed with recipe settings at the time of manufacture and is ready to operate out of the
box. New menu settings can be loaded via USB or smart card (page 31) or programmed manually
(page 33). If settings are not present, the oven will cook only in manual mode (page 23).
This oven uses impingement and microwave to cook food faster than traditional cooking methods. Air enters
the cavity from the top and bottom using independent fans. Because of this design and to ensure uniformity
of cooking, the oven must be operated only while the top and bottom jetplates are in place. While the
bottom jetplate is removable for cleaning, it is not removable for cooking. Without the bottom jetplate in
place, the oven will not deliver the proper cooking performance to either the top or bottom of the food item.
Additionally, oven damage may result.
The sequence of the steps below may vary, and some may not apply.
Step 1: Touch “Menu” or the Oven Set Temperature Icon to Turn the Oven On
Step 2: Select Cook Temperature
Step 3: Warming Up
NOTE: If the temperatures are the same, or if Manual Mode
is disabled, this screen will be bypassed.
NOTE: When the oven is done warming up, it will
“soak” for an additional eight minutes. “Soaking” ensures
the cavity surfaces absorb enough heat so that cooking
will not be affected.

Convection System
The convection system is designed to rapidly heat,
clean, and recirculate air into the cook cavity.
This section contains information about the
following components:
- Blower motor (bottom)
- Blower motor (top)
- Blower motor speed controller (BMSC)
- Heater elements
- Jetplate (bottom)
- Jetplate (top)
- Stirrer motor and assembly
For information on accessing and removing parts,
see the Appendix.
Blower Motor (Bottom)
The bottom blower motor is a brushless AC-switch
reluctance type and spins clockwise. Its top speed
is 7100 RPM at 1 HP, and it is controlled by a
proprietary controller.
The bottom blower motor can be tested in Test
Mode (see page 14, 29 for Touch).
Blower Motor (Top)
The top blower motor is a brushless AC-switch
reluctance type and spins counterclockwise. Its top
speed is 7100 RPM at 1 HP, and it is controlled
by a proprietary controller.
The top blower motor can be tested in Test Mode
(see page 14, 29 for Touch).
Blower Motor Speed Controller (BMSC)
The motor controller is proprietary and will only
operate the motors described above. It is controlled
via 0-10 VDC speed command from the I/O
control board and can be tested in Test Mode by
testing the blower motors (see page 14). For
additional troubleshooting, see page 33.
Heater Elements
The main convection heaters are sheathed-style
and rated at 3000 watts at 208 VAC, with a
resistance of 14.4 Ohms. The convection heaters
are controlled by the K4/K5 solid state relay, and
can be tested in Test Mode (see page 14, 29 for
Touch).
Jetplate (Bottom)
The bottom jetplate channels air generated from
the bottom blower motor into the cook cavity.
Jetplate (Top)
The top jetplate channels air generated from the
top blower motor into the cook cavity. Before the
air passes through the jetplate nozzles, it is mixed
by a stirrer.
CAUTION: The top jetplate is ceramic. Be
careful when removing or reinstalling it.
Stirrer Motor and Assembly
The stirrer is responsible for evenly distributing
hot air and microwave that enters the cook cavity
from the top. The stirrer is driven by a motor that
remains on during a cook cycle or when the oven
is in Test Mode. The stirrer motor turns off when
the cook cavity temperature recedes below 150°F
(66°C).
The stirrer motor can be tested in Test Mode (see
page 14, 29 for Touch).
Troubleshooting
The following faults may occur in relation to the
convection system:
- F1: Blower (see page 57)
- F2: Low Temp (see page 58)
- F6: EC Temp (see page 61)
- F7: Thermo (see page 61)
- F8: Heat Low (see page 62)

Oven Door
This section contains information about the
following components:
- Oven door
- Interlock switches
This section also contains procedures for:
- Removing/reinstalling the oven door
- Adjusting the oven door
- Adjusting the primary, secondary, and monitor
switches
- Measuring RF leakage for microwave safety
For information on accessing and removing parts,

The oven door assembly consists of a shunt plate,
skin, and handle. Each of these items can be
serviced and replaced independently.
NOTE: The proper fit and adjustment of the
oven door is essential for safe and reliable
oven operation.
7. From Test Mode, check the status indicators
“P” “S” and “M” to verify the switches engage
(door closed) and disengage (door open)
properly. If they do not, adjust the switches
per the instructions on page 45.
8. Complete a microwave leakage test (page 46).
Figure 32: Insert Rivet/Screw/Nail to Keep Hinge Open
Adjusting the Oven Door
WARNING: This procedure is performed
while the oven is hot. To avoid burns, be
careful when adjusting the door.
Removing/Reinstalling the Oven Door
To remove or reinstall the oven door, follow the
steps below. For illustrations, see page A-2 of the
Appendix.
1. Ensure the oven has cooled to 150°F (66°C).
2. Open the oven door to its full open position
and insert rivets, screws, or nails as shown in
Figure 32 to hold the hinges in the open
position.
3. Remove the plastic caps and inset 5/16” hex
screws (2 per side). This will allow the hinge
blocks to be removed together with the door.
4. If removing the door without the hinge
blocks, remove the #8-32 screws (3 per side).
5. Carefully remove the oven door by pulling it
away from the oven.
6. Reinstall (or replace) the door and/or hinge
blocks, verifying that the door is parallel to the
oven frame. If it is not parallel, adjust the door
per the adjacent instructions.
1. Open the door and remove the plastic caps.
2. Ensure that the 3 screws on each side of the
door are tight.
3. Loosen the hex screws and close the door.
4. Tap the center of the door to allow door and
frame to align properly. The hinge springs
will pull the door to the frame; do not push
on either side, rather only in the center.
5. Tighten the screws and reinstall the caps.
6. Plug in the oven and perform a microwave
leakage test (see page 46).
Critical Adjustment Notes
If the top or bottom of the door is rotated away
from the oven cavity frame, the door is misaligned.
Corrective Action
1. Loosen the hex screws and push the door
towards the flange.
2. The hinge springs will naturally pull the door
to the flange. Tap the center to ensure a level
surface and proper seal.
Continued on page 45.
Page 73
45
NOTE: Do not push one end at a time, which
could cause the opposite end to lift away from
the flange.
3. Re-tighten the hex screws.
4. Pull the door open only 0.25” (6 mm) and let go
of the handle.
The door must completely snap shut on its own. If the
door sticks and force is needed to finish closing it, it is
out of adjustment.
WARNING: Perform a microwave leakage test
(page 46) after adjusting the oven door.
Interlock Switches
The primary, secondary, and monitor interlock
switches engage and disengage in sequence to ensure
a proper seal. When the door is opened, the switch
sequence is P, S, M. Subsequently, the sequence is M,
S, P when the door is closed.
Adjusting the Primary, Secondary, and
Monitor Switches
WARNING: This procedure is performed while
the oven is hot. To avoid burns, be careful
when adjusting the switches.
Use the following procedure to adjust the primary,
secondary, and monitor switches. The secondary
switch is located on the left side hinge assembly
and the monitor switch is located on the right side
hinge assembly. The primary switch is located on the
upper-left corner of the oven and utilizes an actuator
(attached to the door) and toggle assembly (attached
to the chassis) to engage (Figure 33). See page A-8 of
the Appendix for switch assembly detail.
1. Ensure the oven has been at operating temperature
for at least fifteen minutes.
2. If adjusting the primary switch, confirm the
primary switch’s latch toggle is in the correct
position.
a. Visually inspect the latch toggle position and
verify it is angled at no less than 85° and no more
than 90° in reference to the front flange (oven
face). See Figure 33.
b. If the toggle is less than 85° or greater than 90°,
correct the toggle’s position by installing a
spacer/shim (the more distance from the flange,
the less angle on the toggle):
- NGC-1169-1: Shim, 0.030” (0.762 mm)
- NGC-1169-2: Shim, 0.045” (1.143 mm)
c. Verify the position of the toggle by opening and
closing the oven door several times.
3. Adjust the switch(es):
a. Enter Test Mode (page 14, 29 for Touch).
b. Open the oven door and verify P, S, and M
disengage in sequence.
c. Close the oven door and verify M, S, and P
engage in sequence.
d. If the switches do not engage or disengage in
sequence, close the door and adjust the
necessary switch(es) by loosening the two #4-40
screws and #8-32 screw until the proper
sequence is achieved.
NOTE: DO NOT allow the switch paddle to rest
on the body of the switch in the closed door position. The final adjustment requires a minimum of
a 0.030” (0.762 mm) gap to avoid over-travel and
bent/damaged switches.
4. Open and close the door several times to verify
the switch gap.
0.030” (0.762 mm) Gap

85° - 90° angle
5. Energize the microwave system and open the
oven door.
6. Verify the W indicator is backlit, meaning the
microwave system turns off when the door is
open.
7. Perform a microwave leakage test (page 46).

Measuring RF Leakage for Microwave Safety
WARNING: This procedure requires work with
hot surfaces and water loads. To avoid burns, be
careful when testing.
An RF (microwave) leakage test must be performed
at the conclusion of the following service tasks:
- Door removal, replacement and/or adjustment
- Waveguide removal and/or replacement
- Magnetron removal and/or replacement
- Door switch adjustment and/or replacement
WARNING: If the unit fails the microwave
leakage test (leakage greater than 5mW/cm2),
the oven must be taken out of service
immediately until the defect is corrected. In
addition, the CDRH Regulation 21 Subpart C,
1002.20 requires that leakage readings of over
5mW/cm2 must be reported to the manufacturer.
To measure RF leakage,
4. Close the oven door and press the Enter key.
The microwave system will turn on.
5. Measure microwave emission around the door as
shown in Figure 34, moving the meter sensor at
0.5 inches/second.
6. As microwave leakage is observed while moving
the sensor, note any meter spike areas that come
close to 5mW/cm2 for later re-measurement.
7. Replace the water load every 60 seconds until
the test is completed, and also after scanning
the door.
8. Close the oven door and return the meter probe
to any “meter spike” areas and allow the probe to
remain in the “spike” area for 17 seconds. Note
the highest reading obtained.
NOTE: There may be several places on the door
where this procedure needs to be done. If so, start
out with a fresh water load each time a new area is
measured, or if measurement of an area takes longer
than 60 seconds.
1. Turn the oven on (page 8, 20 for Touch) and
allow it to warm up to the set temperature
(approximately 15 minutes if the oven starts cold).
2. Once the oven has warmed up, ready the oven
for the test.
For Non-Touch Enabled Ovens:
a. Place the oven in Test Mode (see page 14).
From Test Mode, select Manufacturing Mode.
b. From the Manufacturing Mode screen, select
“MW Leak Test” and follow the instructions on
the screen (also detailed in the following steps).
For Touch Enabled Ovens:
a. Place the oven in Manual Mode (page 23).
b. From Manual Mode, create a 1 minute recipe with
a single event, 10% air, and 30% microwave.
3. Place a water load into the cook cavity. The
water load must conform to the following
specifications:
- Volume: 275 ml ± 15 ml
- Temperature: 68ºF ± 9ºF (20ºC ± 5ºC)
- Vessel: Low form, 600 ml beaker with an
inside diameter of approximately 3.35” (85
mm) and made of Pyrex or equivalent.
9. After each test is complete, open the oven door
and dispose of the hot water.

Microwave System
The Sota oven employs left and right microwave
systems. In the case of an over-current situation, the
F3 fuse will blow, shutting off both systems immediately.
NOTE: The Single Magnetron Sota oven utilizes a
single microwave system.
This section contains information about the
following components:
- Capacitors
- Filament transformers
- High-voltage transformers
- High-voltage diodes
- Magnetrons
- Stirrer motor and assembly
- Waveguides
This section also contains procedures for:
- Testing a capacitor
- Wiring the filament transformers
- Testing a filament transformer
- Testing a high-voltage diode
- Wiring the high-voltage transformers
- Testing a high-voltage transformer
- Testing a magnetron for an open/shorted
filament
For information on accessing and removing parts,
see the Appendix.
4. Check for an open or shorted capacitor by
placing ohmmeter leads between the capacitor terminals:
- Escalating ohm readings = capacitor OK
- Constant infinite resistance = capacitor open
- Constant very low resistance = capacitor
shorted
5. If the capacitor is not open or shorted, set the
meter to measure capacitance and again place
the leads between the capacitor terminals. The
meter reading should equal the label value, plus
or minus 10%. If not, replace the capacitor.
NOTE: The Single Mgnetron Sota uses only one
capacitor.
Filament Transformers
For better operation and reliability, the oven
uses separate transformers in order to preheat the
magnetron filament.
The control energizes the filament transformers for
approximately five seconds prior to energizing the
microwave circuit via the high-voltage transformers. When in operation, the filament transformers
supply approximately 3.15 VAC at 10 amps to each
magnetron filament. The filament transformers are
controlled via the K1 relay.
NOTE: The Single Mgnetron Sota uses only one
fialment transformer.
Wiring the Filament Transformers
Capacitors
- Capacitor rating is 0.91uF, 2500 VDC for all
60 Hz installations (except Japan).
- Capacitor rating is 1.15uF, 2500 VDC for all
50 Hz installations.
- Capacitor rating is 0.85uF, 2500 VDC for
60 Hz Japan installations.
Testing a Capacitor
DANGER: Never attempt any measurement
of the capacitors while they are enabled.
Lethal voltage will be present. Measure only
in compliance with these procedures.
1. Disconnect the oven from the power source.
2. Fully discharge the capacitor.
3. Isolate the capacitor from the circuit.
The installation of filament transformers is straightforward. Filament transformers are wired in-phase
and in-line. Refer to the schematic on page 79,
detailing the proper wiring.
NOTE: The Single Mgnetron Sota uses only one
fialment transformer.
To verify correct wiring (North America),
measure the voltages between terminals 1 & 2 and 1
& 3 on FT1 and FT2. The voltages must be 208 and
240 VAC respectively.
NOTE: The orange wire always goes to terminal 3
on US models.
To verify correct wiring (International), measure the
voltage between the taps on FT1 and FT2. The
voltage must be 230 VAC.
OVEN SYSTEMS

High-Voltage Transformers
High-voltage transformers are ferro-resonant, which
limits faulty currents and minimizes magnetron power
changes due to input voltage changes. The high-
voltage transformer supplies the high voltage for the
voltage doubler circuit. They are controlled via the
K8 relay.
NOTE: The Single Mgnetron Sota uses only one high
voltage transformer.
Wiring the High-Voltage Transformers
DANGER: Never attempt to wire or
measure the secondary voltage values of the
high-voltage transformers. Lethal voltage
will be present.
The proper reinstallation of a high-voltage transformer
is critical. Upon removing a high-voltage transformer,
make sure to note where each wire was installed. Refer
to the oven schematic (page 79) for wiring detail.
As shown in the schematic, transformers are installed
mirror opposite and wired 180º out-of-phase. It is
essential for longevity that the high-voltage transformers remain 180º out-of-phase. This can be checked
by placing a volt meter across terminals T1-1 and T2-1
(primary voltage).
Testing a Filament or High-Voltage Transformer
DANGER: Never attempt to measure the
secondary voltage values of the HV
transformers. Lethal voltage will be present.
1. Disconnect the AC power source and discharge
the high-voltage capacitors.
2. Disconnect all the wires in question going to and
from the transformer.
3. Use an ohmmeter to check the impedance of the
primary and secondary winding. Refer to Figure 36,
page 49 to determine if the transformer is okay. If
the resistance is different than the table indicates,
replace the transformer.
High-Voltage Diodes
The high-voltage diode (Figure 35) is assembled by
connecting several 1000-1500 volt semi-conductor
diodes in a series to increase the reverse voltage
capability. In the circuit, the high-voltage diode
conducts to prevent the filament voltage from
becoming positive, thus as the high-voltage winding
of the transformer goes to a peak of 2400 volts, the
high-voltage capacitor is charged to 2400 volts.
NOTE: The Single Mgnetron Sota uses only one high
voltage transformer.
With the microwave system energized, the volt meter
will read the incoming voltage (different readings for
different electrical installations). If the meter reads 0
VAC, the high-voltage transformers are most likely
wired in-phase. As a last check, energize the microwave
system and verify the voltages between the taps on each
high-voltage transformer.
The wiring issue must be corrected prior to returning
the oven to service, as the voltages must be:
- : 208 VAC between 1 & 2 and
240 between 1 & 3.
- : 230 VAC
NOTE: The orange wire always goes to terminal 3 on
US models.
Figure 35: High-voltage Diode
When the high-voltage winding starts to go toward
negative, the high-voltage diode becomes nonconducting with the charged high-voltage capacitor
in series with the high-voltage winding. When the
transformer gets to its negative peak of -2400 volts,
the voltage applied to the filament is -4500 volts. The
high-voltage diodes are rated at 16 kVDC.
NOTE: The Single Mgnetron Sota uses only one diode.

DANGER: Never attempt to measure high
voltage directly. Death or serious injury
could result.
1. Disconnect the oven from the power source.
2. Fully discharge the capacitors.
3. Connect the voltage meter in series with high voltage diode.
4. Using a multimeter set to DC voltage, connect
one meter lead to one side of a 9-volt battery
and the other lead to one side of the high-voltage
diode.
5. Connect the other side of the 9-volt battery to
the other side of the high-voltage diode. DC
voltage should be present on the meter in only
one direction.
6. Switch the meter leads on the high-voltage diode,
which will cause the opposite reading to be
visible. Depending on the voltage of the battery,
voltage between 5-7 VDC should be present in
only one direction and 0-0.1 VDC in the other

removing the wires from the F and FA terminals.
Figure 37.
Waveguides
The waveguides channel microwave into the cook
cavity. If debris or contamination gets into the
waveguides, the life of the magnetrons may be
shortened. Be careful to not allow debris into the
waveguides when servicing the magnetrons or stirrer
assembly.
NOTE: The Single Mgnetron Sota uses only one
waveguide.

Cooling Fans
Display, TFT (For Non-Touch Enabled Ovens)
The TFT display is the primary user interface.
Both 24 VDC and 5 VDC are supplied from the
control board through the 3-pin power cable. 24
VDC is used for the backlighting and 5 VDC is
used for the logic systems.
Display (Touch) and UI Control Board (Phoenix)
On touch-enabled ovens, the touch display is the
primary user interface. It is a 7 in. capacative touch
screen with a tempered protective glass cover.
Included with the display is the UI control board
(Phoenix). The Phoenix control board handles all
UI-related tasks, including graphics, menu and data
storage, and programing/data transfer, such as USB,
smart card, and Wi-Fi.
Electrical Compartment Cooling Fan
Thermostat
The cooling fan thermostat actuates the five rear
cooling fans when the electrical compartment
temperature reaches 120ºF (49ºC).
Electrical Compartment Thermocouple
The electrical compartment thermocouple is part
of the control board and measures the temperature
of the electrical compartment. If it is above 158ºF
(70ºC), an F6: EC TEMP fault will display. The
control board checks the electrical compartment
temperature once every 60 seconds.
There are seven total cooling fans. The three fans
across the top of the back panel are inlet fans and
the other four are outlet fans.
The four electrical compartment cooling fans on
the back panel and the one underneath the oven
are actuated by the cooling fan thermostat when
the temperature of the electrical compartment
reaches 120ºF (49ºC). The two magnetron cooling
fans (located on each side of the oven) are actuated
by the K2 relay when the magnetrons are in operation, and remain on for four minutes and fifteen
seconds after the magnetrons turn off. They operate at:
- 208/240 VAC (60 Hz with voltage sensing)
- 220 VAC (60 Hz with no voltage sensing)
- 230 VAC (50 Hz installations)
EMI Filter
The EMI filter helps suppress the amount of RF
interference emitted by the oven.
Ethernet Extension Cable
The ethernet extension cable exits the oven at the
back panel and allows the oven to be connected to
a local network, in case the customer desires remote
programming and oven diagnostics reporting.

Fuses
The F1 and F2 fuses are 12-amp, ATMR, class CC.
The F3 fuse is 20-amp, ATMR.
The F1 fuse (via blue wire) and F2 fuse (via brown
wire) are designed to blow if an over-current
situation is encountered by the motor controller,
any cooling fan, either filament transformer, power
supply, or stirrer motor. The F3 fuse is designed
to blow in case of an over-current situation relative
to the microwave system (magnetron, high-voltage
transformer, diode, capacitor).
High Limit Thermostat
The high limit thermostat is a 250 VAC, 3-pole,
manual-reset thermostat with a trip point of 572ºF
(300ºC). The thermostat interrupts power to the
main convection heater in the event of an abnormal
condition. Reset the high-limit thermostat by
pressing the reset button (Figure 38).
Reset
Button
Magnetron Thermostats
The magnetron thermostats are “open-on rise.”
They are designed to open at 270ºF (132ºC),
which triggers an F5 fault.
NOTE: Except for Single Magnetron Sota Ovens
(where only one magnetron thermostat is used) the
magnetron thermostats are wired in series. If one
opens, the control will switch off both magnetrons
until the open thermostat closes. The thermostats
are self-resetting.
Power Supply
The power supply outputs 24 VDC at 40 watts to
the control board and relays.
Relay - K1 Filament
The K1 relay is a 240 VAC, 24 VDC coil, 20 amp,
sealed single-pole relay. It switches power to the
filament transformers.
Relay - K2 Magnetron Cooling Fans
The K2 relay is a 240 VAC, 24 VDC coil, 20 amp,
sealed single-pole relay. It switches power to the
magnetron cooling fans when the magnetron
filaments are actuated. Power is switched off after
four minutes and fifteen seconds.
Figure 38: High-Limit Reset Button
I/O Control Board (SAGE)
The I/O control board (SAGE) controls each electrical component of the oven. 24 VDC can be measured at pin 2 of the J7 connector to confirm control
voltage is being applied (see page 79).
Keypad (For Non-Touch Enabled Ovens)
The keypad is a 8 x 11 matrix membrane switch.
For details on key functions, see page 7.
LED Light Ring (Soˇ ta only)
The LED light ring provides visual cues in regards
to oven operation, and counts down the final 30
seconds of each cook cycle.
NOTE: The four-minute, fifteen-second timer
starts over each time the magnetron filaments are
actuated.
Relay - K3 Stirrer Motor
The K3 relay is a 240 VAC, 24 VDC coil, 20 amp,
sealed single-pole relay. It switches power to the
stirrer motor.
Relay - K6 Voltage
The K6 relay is a 240 VAC, 30 amp, three-pole,
double-throw, 24 VDC relay coil. Operational in
North America only, it switches between 208 and
240 VAC on the HV transformer and filament
transformer taps (depending on incoming voltage).
Through the voltage sensor, the oven defaults to the
240V position and switches to 208 if less than 222
volts is detected. 230V/400V international ovens
and all Japan models utilize the N.C. contacts of the
relay to power the microwave transformers.
Page 81
53
Relay - K7 Monitor
The K7 relay is a 240 VAC, 30 amp, double-pole,
double-throw, 24 VDC relay coil. It shorts L1 and
L2 if the monitor switch opens before the primary
or secondary switches.
Relay - K8 Anode
The K8 relay is a 240 VAC, 30 amp, double-pole,
double-throw, 24 VDC relay coil. It switches power
to the high-voltage transformers.
RTD
The RTD measures the temperature of the heater
element. If the display reads “999°F/C”, the RTD
is open, resulting in an F7 fault. See page 61 for
troubleshooting.
Testing Procedure:
1. Disconnect the RTD from the control harness.
2. Place the RTD in ice water for two minutes.
3. Take a resistance reading of the RTD.
4. If RTD resistance is not 100 Ω, the RTD is
defective and must be replaced.
NOTE: Use Figure 39 below to determine resistance readings at temperatures other than freezing.
Speaker
The speaker provides audible feedback to the oven
operator whenever a key is pressed or a task (such
as a cook cycle) is completed.
USB/Smart Card Reader
The USB/smart card reader allows the oven operator
to load menus and firmware updates to and from a
USB thumb drive or smart card. For instructions,
see page 16, 31 for Touch. USB functionality is not
present on some Sota ovens.
Voltage Sensor
For North America models only. Voltage selection
is completed at the time of manufacture; however,
if incoming voltage for the store is different than
the preset voltage, the operator will be required to
select either 208 or 240 after turning on the oven.
The correct voltage will be enlarged on the screen,
identifying which option to select.
Wire Harness
The wire harness distributes power to the oven’s
electrical components. See page 79 for schematic.
Troubleshooting
Solid State Relay - K4/K5 Heater
The solid state relay is a 240 VAC, dual 40-amp
relay. K4 switches power to heater one, and K5
switches power to heater two.
The control system could potentially be related to
the cause of any fault (see pages 33-38 for detailed
fault troubleshooting).
The control system might also be related to any
issue diagnosed in the section “Non-Fault Code

Filtering System
This section contains information about the
following components:
- Catalytic converter
- Air filter
- Vent catalyst
Catalytic Converter
The catalytic converter, a VOC type catalyst, is
located behind the inside cook cavity wall and is
responsible for cleaning the recirculating airflow.
The catalyst functions by substantially lowering
the combustion temperature of grease entrained in
the air path to approximately the same temperature
of the airflow; thus the grease burns and breaks
down into CO2 and H2O as it passes through the
catalytic converter. The catalyst will operate most
efficiently at temperatures above 475ºF (246ºC).
The catalyst material is very sensitive to certain
chemical compounds. Irreversible damage can
occur if the catalyst is exposed to cleaning
chemicals containing phosphates, NaOH, silicates,
Na and Potassium Salts. These chemicals are found
in most commercial degreasers and cleaners;
therefore, only TurboChef® Oven Cleaner should
be used.
CAUTION: Clean the catalytic converter
with TurboChef Oven Cleaner and rinse
thoroughly with distilled water. Let the
catalytic converter air dry before reinstalling.
If TurboChef Oven Cleaner is not available,
use only distilled water.
Air Filter
The filter is located on the back of the oven. It
helps prevent debris from getting into the electrical
compartment through the cooling fans. This
component requires scheduled maintenance and
occasional replacement, as it must be kept clean
and in good working condition to ensure proper
air circulation to the electrical components of the
oven. See page 5, step 4 for details.
Vent Catalyst
In addition to the main catalytic converter, the
NGO oven contains a secondary catalyst in the
vent tube path. This catalyst further assists in the
breakdown of grease and particulate matter before
the excess air enters the atmosphere.
Troubleshooting
The following issues may occur in relation to the
filtering system:
- F9: CC Temp (if the catalyst is clogged with
grease and debris - see page 62)
- Fire in the cook cavity (if catalytic converter is
clogged and oven is not regularly cleaned).
- Electrical component failure (if filter is not
present or is clogged).
- Undesirable flavor transfer.
- Undesirable odor emissions.

Overview of Troubleshooting
This section contains information on the
following:
- Fault code descriptions
- Fault code troubleshooting
- Non-fault code troubleshooting
For information on accessing Test Mode, see page
14. For information and illustrations on replacing
components, see the appendix.
Fault Code Descriptions
To view the fault log see page xx.
F1: Blower Running Status Bad
This fault is displayed when the motor controller
indicates no running status.
The motors and motor controller are monitored
continuously in all modes with special handling in
the Test Mode (page 14, 29 for Touch). If a fault is
detected, the control will terminate a cook cycle and
display “F1: Blower.”
Upon turning on the oven, the control will attempt
to restart the motors. If the restart of both motors
is successful, the fault code will be cleared from the
display. The fault is also cleared from the display
at the onset of cooking or when a blower motor is
tested in Test Mode.
F3: Magnetron Current Low
This fault is displayed when the current transformer
(CT) on the I/O control board detects less than 10
amps. The fault is monitored when the microwave is
on during a cook cycle or in Test Mode.
The fault is cleared from the display at the onset of
a cook cycle if the CT detects 10 amps, or when the
magnetrons are successfully energized in Test Mode.
F4: Door Monitor Defective
This fault is displayed when the control detects that
the monitor interlock switch unlatches before the
primary or secondary interlock switches. In addition, this fault will blow the F3 fuse if the microwave high voltage system is energized when the fault
occurs. The fault is cleared from the display when
the oven is powered off and then back on.
NOTE: Door interlock switches are in parallel.
See the oven schematic, page 79. The fault is
monitored during a cook cycle and in Test Mode
when the microwave is on.
F5: Magnetron Over Temperature
This fault is displayed when either magnetron thermostat reaches 212ºF (100ºC).
The thermostats will reset automatically, and
are wired in series. The fault is cleared from the
display at the onset of a cook cycle if the thermostat
is closed.
F2: Cook Temperature Low
This fault is displayed if the cook cavity
temperature is more than 84ºF (47ºC) below the set
temperature after five seconds into a cook cycle.
The fault is cleared from the display at the onset
of cooking if the cook cavity temperature is within
84ºF (47ºC) of the set temperature or when the
heater is tested in Test Mode (page 14, 29 for
Touch).
NOTE: The Single Mgnetron Sota uses only one
magnetron thermostat.
F6: Electrical Compartment Temperature High
This fault is displayed when the EC thermocouple
exceeds 158ºF (70ºC). The EC temperature is monitored once per minute.
The fault is cleared from the display if on the next
check, the EC thermocouple temperature is below
158ºF (70ºC).
TROUBLESHOOTING

56 TROUBLESHOOTING
F7: RTD Open
This fault is displayed when the control detects that
the RTD is “open.” The display will show a reading
of “999ºF/C,” indicating the RTD is open.
The fault is cleared when the control detects
continuity.
F8: Heat Low
This fault displays when the oven is warming up or
during Test Mode if the cook cavity temperature
fails to rise at least 14ºF (7ºC) within a given 30
seconds.
F9: Cook Cavity Temperature High
This fault will signal that the catalyst has “flashed”
due to excessive grease. The fault occurs when the
RTD senses +650°F (343°C) for more than 40
