Installation Warnings - Read Before
Lifting Oven

WARNING: The Eco oven weighs
approximately 118 lb. (54 kg). TurboChef
recommends lifting the oven with no fewer
than two people.

WARNING: Never lift the oven by the door
handle. Doing so will cause the door to
misalign, resulting in a non-warranty service call.

WARNING: The oven must be properly placed
on a food station at all times. TurboChef will not
recognize a fallen oven as a warrantable claim and
is not liable for any injuries that may result.

WARNING: This oven is not intended for built­ in installation (i.e., installing the oven in any
structure that surrounds the oven by five or more
sides). Be sure to provide a minimum of 2” (51
mm) clearance for all sides and 5” (127 mm)
clearance for the top.

WARNING: This oven is intended to be stacked
only with appropriate hardware. Never stack any
more than two high.

Lifting and Placing the Oven

1. Prepare a surface at least 23.5” (597 mm) deep

and capable of supporting 120 lb. (54 kg).

2. Position one or more persons at the left and

right sides of the oven.

3. Place hands under the oven and lift.

4. Place the oven on the prepared surface ensuring

no edges are hanging off the sides.

Partition

5. If stacking two ovens:
a. See page 1 for dimensions.
b. Install the stacking bracket (ECO-9420) to
the lower oven.
c. Place the upper oven on top of the lower oven.
d. Secure the bracket to the top oven.

6. Ensure the oven rack is properly installed
(attached to the bottom jetplate).

7. Ensure the lower panel (crumb tray) is attached
below the oven door.

8. Plug in the oven.

NOTE: The oven is primarily serviced through its
top. DO NOT install shelving directly over the
unit. The operator will be responsible for service
charges incurred as a result of added time required
to access the top of the oven.

Installation Near Open Heat Source

When placing a TurboChef oven near an open heat
source (Figure 2), strictly adhere to the following:

• If the oven is being placed near a grill or stove,

a divider must exist between the oven and the

OVEN CONTROLS AND COOKING

OVEN CONTROLS AND COOKING8

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 (page 19), programmed manually (page 21) or via
Middleby Connect™ on page 4.

If settings are not present, the oven will cook only in manual mode (page 11).
This oven uses impingement and microwave to cook food faster than traditional cooking methods. Air enters

the cavity from the top and bottom using a single fan. Because of this design and to ensure uniformity of
cooking, the oven must be operated only while the bottom jetplate is 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, a
non-warranty service call 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

Figure 5: Turn the Oven On (Menu or Manual) Figure 6: Set Oven Temperature

Step 2: Select Cook Temperature

NOTE: If the temperatures are the same, or if Manual Cook
Mode is disabled, this screen will be bypassed.

Figure 7: Oven Temperature Display

Step 3: Warming Up

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.

Impingement System

The impingement system is designed to rapidly
heat, clean, and recirculate air into the cook cavity.

This section contains information about the
following components:

• Blower motor

• Blower motor speed controller (BMSC)

• Heater elements

• Jetplate

• Stirrer motor and assembly

For information on accessing and removing parts,
see the Appendix.

Blower Motor

The blower motor is a brushless AC-switch
reluctance type and spins counter clockwise. Its top
speed is 7100 RPM at 1 HP, and it is controlled by
a proprietary controller.

The blower motor can be tested in Test Mode (see
page 18).

Heater Elements

The heaters are sheathed-style and rated at 2250
watts at 208 VAC, with a resistance of 14.4 Ohms.
The heaters are controlled by the K4/K5 solid state
relay, and can be tested in Test Mode (see 18).

Jetplate

The bottom and top jetplates channel air generated
from the blower motor into the cook cavity.

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
oven is not cooking.

The stirrer motor can be tested in Test Mode (see
page 18).

Blower Motor Speed Controller (BMSC)

The motor controller is proprietary and will only
operate the motor described above. It is controlled
via (0-9.5) VDC speed command from the Sage
control board and can be tested in Test Mode
by testing the blower motor. For additional
troubleshooting, see page 47.

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,
see the Appendix.

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.

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 74 to hold the hinges in the open
position.

3. Remove the plastic caps and 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.

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 35.

8. Complete a microwave leakage test (see page 36).

Figure 74: 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.

1. Open the door and remove the plastic caps (4),
2 on each side.

2. Ensure that the 2 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 36).

7. Repeat as necessary until within specifications.

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.

35

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 36) 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. The sequence is M, S, P as 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 primary
and secondary switches are located on the left side
hinge assembly and the monitor switch is located
on the right side hinge assembly. The primary and
secondary switches utilize an actuator (attached
to the door) and toggle assembly (attached to the
chassis) to engage (Figure 75). See page A-5 of the
Appendix for switch assembly detail.

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).

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 18).
b. Open the oven door and verify P and S

disengage before M.

c. Close the oven door and verify M engages

before S, and P.

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: The sequence of P in relation to S is not
important, rather, both P and S need to open before
M and close after M.

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.

1. Ensure the oven has been at operating
temperature for at least fifteen minutes.

2. If adjusting the primary or secondary switch,
confirm the latch toggle is in the correct
position.

Figure 75: Primary Switch Adjustment

NOTE: An over-rotated switch paddle can cause the
paddle to not engage the switch button properly.
Do not over-rotate the switch paddle.

4. Open and close the door several times to verify
the switch gap.

5. Perform a microwave leakage test (page 36).

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.

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.

9. After each test is complete, open the oven door
and dispose of the hot water. Let the steam
dissipate with the door open.

To Measure RF Leakage

1. Turn the oven on (page 7) 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:

a. Place the oven in manual mode (page 11).
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: Pyrex dish capable of 500º F

4. Close the oven door and press the Cook key.
The microwave system will turn on.

5. Measure microwave emission around the door
slowly as shown in Figure 76, 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.

Microwave System

The Eco oven utilizes a single magnetron system.
In the case of an over-current situation, the F3 fuse
will blow, shutting off the system immediately.

NOTE: The Eco oven utilizes a single magnetron
system.

This section contains information about the
following components:

• Capacitor

• Filament/High-voltage transformer

• High-voltage diode

• Magnetron

• Stirrer motor and assembly

• Waveguide

This section also contains procedures for:

• Testing a capacitor

• Testing a filament portion of the transformer

• Testing a high-voltage diode

• Wiring the high-voltage transformer

• Testing a magnetron for an open/shorted filament

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 4% maximum. If not, replace the
capacitor.

Combination HV/Filament Transformer

The control energizes the filament portion of the
transformer in combination with the high-voltage
(step up) portion of the transformer.

When in operation, the filament portion of the
transformer supplies approximately 3.15 VAC at 10
amps to the magnetron filament. The high-voltage
portion of the transformer supplies the high voltage
for the voltage doubler circuit.

The filament/high-voltage transformer is controlled
via the K2 Anode relay.

Wiring the Transformer

DANGER: Never attempt to wire or measure
the secondary voltage values of the transformer.
Lethal voltage will be present.

For information on accessing and removing parts,
see the Appendix.

Capacitor

The capacitor value will vary by country. Reference
the schematic (page 63) for proper values.

Testing a Capacitor

DANGER: Never attempt any measurement
of the capacitor while it is 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.

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

The proper reinstallation of the transformer is
critical. Upon removing the transformer, make sure
to note where each wire was installed. Refer to the
oven schematic (page 63 for wiring detail.

With the microwave system energized, the volt
meter will read the incoming voltage (different
readings for different electrical installations).

The wiring must be correct prior to returning the
oven to service, as the voltages must be:

• North America: 208 VAC between 1 & 2 and
240 between 1 & 3.

• International: 230 VAC between T1 & T2

NOTE: The orange wire must always go to
terminal 3 on US models.

OVEN SYSTEMS

Testing the Transformer

DANGER: Never attempt to measure the
secondary voltage values of the transformer.
Lethal voltage will be present.

1. Disconnect the AC power source and discharge

the capacitor.

2. Disconnect all the wires going to and from the

transformer.

3. Use an ohmmeter to check the resistance of the

primary and secondary winding. Refer to Figure

78, below, to determine if the transformer is

good. If the resistance is different than the table

indicates, replace the transformer.

High-Voltage Diode

The high-voltage diode (Figure 77) is assembled by
connecting several 1000-1500 volt semi-conductor
diodes in a series to increase the reverse voltage
capability.

Figure 77: High-voltage Diode

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.

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.

Testing the High-Voltage 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 capacitor.

3. Connect the voltage meter in series with the

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 direction.

CAUTION: Do not allow debris to enter the

waveguides when servicing the stirrer.

Waveguide

The waveguide channels microwave into the
cook cavity. If debris or contamination gets into
the waveguide, the life of the magnetron may be
shortened. Be careful to not allow debris into the
waveguide when servicing the magnetrons or stirrer
assembly.

Troubleshooting

The following faults may occur in relation to the
microwave system:

• F3: Magnetron Current Low (see page 49)

• F5: Magnetron Over Temperature (see page 50)

The following issues may occur in relation to the

Cooling Fans

There are five cooling fans. The three fans across the
top of the back panel are inlet fans and the other
two are outlet fans.

The electrical compartment cooling fans are
actuated by the cooling fan thermostat when the
temperature of the electrical compartment reaches
120ºF (49ºC). They operate at 200-240VAC.

The K7 relay actuates the magnetron cooling
fan and the transformer cooling fan when the
magnetron is in operation. The fans remain on
for four minutes and fifteen seconds after the
magnetron turns off. They operate at 24 VDC.

Display and UI Control Board (Phoenix)

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 transfers,via USB and Wi-Fi.

Electrical Compartment Cooling Fan
Thermostat

The cooling fan thermostat actuates the electrical
compartment cooling fans when the electrical
compartment temperature reaches 120ºF (49ºC).

Electrical Compartment Thermocouple

The electrical compartment thermocouple is
part of the Sage control board and measures the
temperature of the electrical compartment. If it is
above 149ºF (65ºC), an F6: EC TEMP fault will be
displayed on the screen and logged in the fault log;
however, the oven will give the user the option to
continue cooking. If the thermocouple reads above
158ºF (70ºC), the oven will stop cooking. The
control board checks the electrical compartment
temperature once every 60 seconds.

EMI Filter

The EMI filter helps suppress the amount of RF
interference emitted by the oven.

Fuses

The F1 and F2 fuses are 12-amp, ATMR, class CC.
The F3 fuse is 15-amp, ATMR.

The F1 fuse (via brown wire) and F2 fuse (via
blue wire) are designed to blow if an over-current
situation is encountered by the auxilary circuitry,
including the BMSC, any cooling fan, 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, transformer,
diode, capacitor), or if the microwave system is on
when the M (monitor) switch opens, indicating a
door alignment/adjustment issue.

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 80).

Reset Button

Relay - K1 Stirrer Motor

The K1 relay is a 240 VAC, 24 VDC coil, 20 amp,
sealed single-pole relay. It switches power to the
stirrer motor.

Relay - K2 Anode

The K2 relay is a 240 VAC, 30 amp, double-pole,
double-throw, 24 VDC relay coil. It switches power
to the high-voltage transformer.

Relay - K3 Monitor

The K3 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 out of sequence
before the primary or secondary switch.

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.

Figure 80: 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 63).

Magnetron Thermostat

The magnetron thermostat is “open-on rise.” It is
designed to open at 270ºF (132ºC), which triggers
an F5 fault.

NOTE: When open, the control will switch off the
magnetron until the open thermostat closes. The
thermostat is self-resetting.

Power Supply

The power supply outputs 24 VDC at 40 watts to
the control board, relays, speaker, and display/UI
board.

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.

Relay - K7 Magnetron Cooling Fan

The K2 relay is a 240 VAC, 24 VDC coil, 20 amp,
sealed single-pole relay. It switches power to the
magnetron cooling fan when the magnetron
filament is actuated. Power is switched off after
four minutes and fifteen seconds.

NOTE: The four-minute, fifteen-second timer
starts over each time the magnetron filaments are
actuated.

RTD

The RTD measures the temperature of the heater
element. If the display reads “999°F/C”, the RTD
is open, resulting in an F7or F9 fault. See pages 51
and 52 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 81 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

The USB allows the oven operator to load menus
and firmware updates to and from a USB thumb
drive. For instructions, see pages 20-21.

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.

WiFi Module

The WiFi module allows the oven to connect to the
internet via the store’s access point, provided the
user authorizes access and the preset credentials are
entered (see page 15). WiFi must be specified at the
time of the manufature; otherwise the Eco oven will
not include the WiFi module.

Transformer Thermostat

The transformer thermostat is “open-on rise” and
is designed to open at 280ºF (138ºC). When open,

The control system could potentially be related to
the cause of any fault (see pages 45-53 for detailed
fault troubleshooting).

The control system might also be related to any
issue diagnosed in the section “Non-Fault Code
Troubleshooting” on pages 54-61.

Filtering System

This section contains information about the
following components:

• Catalytic converter

• Air filter

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.

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 daily rinsing 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.

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 52).

• 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 or odors.

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.

• Fault code descriptions

• Fault code troubleshooting

• Non-fault code troubleshooting

For information on accessing Test Mode, see page

18. For information and illustrations on replacing
components, see the appendix.

Fault Code Descriptions

To view the fault log see page 17.

F1: Blower Running Status Bad

This fault is displayed when the motor controller
indicates no running status.

The motor and motor controller are monitored
continuously in all modes with special handling in
the Test Mode (page 18). 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 motor. If the restart 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 the blower motor is tested in Test
Mode.

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.

F4: Door Monitor Defective

This fault is logged when the control detects
that the monitor interlock switch opens 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 63. 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 the magnetron
thermostat reaches 270ºF (132.2ºC).

The thermostat will reset automatically. The fault is
cleared from the display at the onset of a cook cycle
if the thermostat is closed.

F6: Electrical Compartment
Temperature High

This fault is displayed when the EC thermocouple,
located on the Sage Board, exceeds 149ºF (65ºC).
If the thermocouple reads above 158ºF (70ºC),
the oven will stop cooking. 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
149ºF (65ºC).

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 18).

F3: Magnetron Current Low

This fault is displayed when the current transformer
(CT) on the I/O control board detects less than 7
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 7 amps, or when the
magnetron is successfully energized in Test Mode.

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 60
seconds.

TROUBLESHOOTING

TROUBLESHOOTING46

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
seconds but less than 2 minutes. The fault will only
appear in the fault log and will not terminate a cook
cycle upon discovery.
