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 remains on during a cook cycle or when
the oven is in
TEST MODE
when the cook cavity temperature recedes 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
page 16).

Convection System Troubleshooting

The following faults may occur in relation to the con-
vection system:
- F1: Blower (see page 37)
- F2: Low Temp (see page 38)
- F6: EC Temp (see page 41)
- F7: Thermo (see page 41)
- F8: Heat Low (see page 42)
- F9: CC Temp (see page 42)
The following cooking performance issues may occur
in relation to the convection system:
- Food not cooking properly (see page 45)

Oven Door

This section contains information about the
following components:
- Oven door
- Interlock switches
- Hinges and counter-balance assembly
This section also contains procedures for:

- Removing/reinstalling the oven door

- Adjusting the oven door

- Adjusting the oven door switches
. The stirrer motor turns off
(see
TEST MODE
- Adjusting the counter-balance assembly
- Measuring RF leakage for microwave safety
For information on accessing and removing parts, see
the Appendix.
NOTE: The proper fit and adjustment of the oven
door is essential for safe and reliable oven operation.
The oven door assembly consists of a shunt plate,
skin, and handle. Each of these items can be
replaced independently.
Removing/Reinstalling the Oven Door
To remove or reinstall the oven door, follow the steps
below. For illustrations, see page A-3 of the appendix.
1. Ensure the oven has cooled to 150°F (66°C).
2. Open the oven door to its full open position.
3. Remove the #8-32 screws (three per side).
4. Carefully remove the oven door by pulling it away
from the oven. It will slide off the hinges, and the
hinge blocks will stay in place. See Figure A-1,
page A-3 of the appendix.
CAUTION: The door hinge is preloaded and
can pinch or injure if allowed to slam closed
without counterbalance pressure.
5. To reinstall or fit a new door, carefully slide it
back over the hinge blocks and replace the six
#8-32 screws (three per side).
6. Verify that the door is parallel to the oven
frame. If it is not parallel, adjust the door per
the instructions in the following section.
7. From (page 16), check the status
TEST MODE
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 24.
8. Complete a MW leakage test (pages 25-26).
Adjusting the Oven Door
Ensuring the oven door is parallel to the cavity frame
is essential for safe and proper oven operation. If the
door is misaligned, follow the proceeding steps.
