Stirrer Motor and Assembly
The stirrer is responsible for evenly distributing hot
air and microwaves that are launched from the top of
the oven into the cook cavity. The stirrer is driven by
a motor that r
emains on during a cook cy
cle or when
the oven is in TEST MODE. The stirrer motor turns off
when the cook cavity temperatur
e r
ecedes below
150°F (66°C).
The i3 utilizes two versions of the stirrer and the
stirrer shaft. Ovens with serial numbers between
00001 and 01000 use a mica stirrer, whereas ovens
with a serial number of 01001 or greater use a metal
stirrer. Each stirrer type also has a unique shaft. For
details including part numbers and illustrations, see
pages A-2 through A-3 and A-6 through A-7 of the
appendix.
The stirrer motor can be tested in TEST MODE (see

for
ward. Filament transformers are wired in-phase and
in-line. R
efer to the schematic on page 49, detailing
the proper wiring.
To verify correct wiring (North America),
measure the voltages between terminals 1 & 2 and 1 &

(Japan), or 230 VAC (International).
High-Voltage Transformers
The high-voltage transformers are of ferro-resonant
design, which limits fault curr
ents and minimizes
magnetron power changes due to input voltage
changes.
The high-voltage transformer supplies the
high v
oltage for the voltage doubler circuit. They are
contr
olled via the K2 relay.
Wiring the High-Voltage Transformers
DANGER
:
Never attempt to touch, contact, or
measure the secondary voltage values of the
high-v
oltage transformers while they ar
e
enabled. Lethal v
oltage will be present.
The pr
oper reinstallation of a high-voltage transformer
is critical. U
pon removing a high-voltage transformer,
make sur
e to note where each wire was installed. See
the o
ven schematic on page 49 for the wiring detail.
As shown in the schematic, transformers are installed
mirror opposite and wired 180ºout-of-phase. It is
essential for longevity that the high-voltage transformers r
emain 180
º
out-of-phase.
This can be checked
b
y placing a volt meter across terminals T1-1 and T2-1
(primar

oltage).
W
ith 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
wir
ed in-phase. As a last check, energize the microwave
system and v
erify the voltages between the taps on
each high-v
oltage transformer
.
The wiring issue must be corrected prior to returning
the o

- NORTH AMERICA: 208 VAC between 1 & 2 and
240
betw
een 1 & 3.
- LATIN AMERICA: 220 VAC
-
JAP
AN: 200 VAC
- INTERNATIONAL: 230 VAC
NOTE: The terminals with the orange dot/orange wire

Testing a Filament or HV Transformer
DANGER
: Never attempt to measure the
secondar
y voltage values of the transformers
when they ar
e connected to the magnetron
cir
cuit. Lethal voltage will be present.
1. Disconnect the AC power source.
2. Remove the top cover of the oven and discharge
the high-voltage capacitors.
3. Disconnect all the wires in question going to the
transformer
.
4.
Use an ohmmeter to check the impedance of the
primar

is OK. If the resistance is different than the table
indicates, r

Voltage Diodes
The high-v
oltage diode (Figure 34) is assembled by
connecting sev
eral 1000-1500 v
olt 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 positiv
e, thus as the high-v
oltage winding
of the transformer goes to a peak of 2400 v
olts, the
high-voltage capacitor is charged to 2400 volts.
Figure 34: High Voltage Diode
Page 49
OVEN SYSTEMS
29
When the high-v
oltage winding starts to go toward
negativ
e, 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 v
oltage applied to the filament is -4500 volts. The
high-v
oltage diodes are rated at 16 kVDC.
T
esting a High-Voltage Diode
DANGER: Never attempt to measure high
voltage directly. Death or serious injury
could r

1. Disconnect the oven from the power source.
2. R
emove the top cover of the oven.
3. F
ully discharge the capacitors.
4. Connect the v
oltage meter in series with the diode.
5. 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 diode.
6.
Connect the other side of the 9-volt battery to
the other side of the diode. DC v
oltage should
only be present on the meter in one direction.
7. Switch the meter leads on the diode, which will
cause the opposite r
eading to be visible.
D

5. A continuity check between either filament terminal
and the magnetr

infinite resistance (open).
CAUTION: Be careful to not allow debris
into the wav
eguides when ser
vicing the
magnetrons.
Stirrer Motor and Assembly
The stirr
er is responsible for evenly distributing hot air
and microwaves that are launched from the top of the
oven into the cook cavity. 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 temperatur
e r
ecedes below 150°F
(66°C).
The i3 utilizes two versions of the stirrer and the
stirrer shaft. Ovens with serial numbers between 00001
and 01000 use a mica stirrer, whereas ovens with a
serial number of 01001 or greater use a metal stirrer.
Each stirr
er type also has a unique shaft. For details
including part numbers and illustrations, see pages A-2
thr
ough A-3 and A-6 through A-7 of the appendix.
The stirr
er motor can be tested in TEST MODE (see
page 16).
W
aveguides
The wav
eguides channel microwaves into the cook cav-
ity
. If debris or contamination gets into the wave-
guides, the life of the magnetr
ons may be shortened.
Be careful to not allow debris into the waveguides
when servicing the magnetrons.

NO
TE: The F2 alarm can be turned off to prevent
the cook cy
cle from being interrupted. See page 14 for
details.
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 monitor
ed when the microwave is
on during a cook cycle or in TEST MODE.
The fault is clear
ed fr
om the display at the onset of a
cook cycle if the CT detects 10 amps or when the
magnetr
ons 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
v
oltage system is energiz
ed when the fault occurs. The
fault is cleared from the display when the oven is
po
wered off and then back on.
NO
TE: See the oven schematic, page 49. The fault is
monitored during a cook cycle and in TEST MODE
when the microwave is on.
F5: M
agnetron Over Temperature
This fault is display
ed when either magnetron thermo-
stat reaches 212ºF (100ºC).
The thermostats will r
eset automatically, and are wired
in series.
The fault is clear
ed from the display at the
onset of a cook cy
cle if the thermostat is closed, or
when the magnetr
ons ar

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
the indicated limit.

ault codes are listed in order of hierarchy. For example, if during cooking the oven experiences both an F1 and
F2 fault, it will r
eport only the F1 fault because the software will halt all actions upon discovering the F1 fault.
Fault codes F1 - F5 and F7 will terminate a cook cycle upon discovery.
F7: RTD Open
This fault is display
ed when the control detects that
the R
TD is “
open” for more than two continuous
minutes. The display will show a reading of
“

if the cook cavity temperatur
e 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 “

due to excessive grease. The fault occurs when the
R
TD 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
