Antenna Motor Removal
1. Disconnect the power supply cord and then remove
outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Remove the hood duct from the oven cavity, referring
to the procedure of “Hood Fan Motor, Hood Duct And
Oven Lamp Socket Removal”.
5. Disconnect the wire leads from the antenna motor.
6. Remove the one (1) screw holding the antenna motor
to the waveguide of the oven cavity.
7. Remove the antenna motor from the waveguide.
8. Now, the antenna motor is free.
9. When installing the antenna motor, the shaft of
antenna motor must be inserted to the stirrer antenna
shaft. Refer to the procedure of “Stirrer Cover And
Stirrer Fan Installation”.
Oven Lamp Removal
1. Disconnect the power supply cord.
2. Remove the hood louver from the oven. (Refer to
procedure of “Hood Louver Removal”)
3. Lift the oven lamp cover up.
4. Now, the oven lamp and the socket are found.
5. Screw the oven lamp off from the lamp socket.
6. Now, the oven lamp is free.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.

Stirrer Cover And Stirrer Fan
Installation
1. Put the stirrer antenna on the wave guide to match
the stirrer antenna shaft to the center of the stirrer
hole.
2. Insert the shaft of stirrer antenna to the shaft of
antenna motor.
3. Rotate the antenna holder to lock at the cavity top
plate.
4. Insert the cutout of stirrer cover to the tabs on the
ceiling.
5. Install the stirrer cover to the oven cavity, and secure
it by one canoe clip.

Precautions for Handling Electronic Components
This unit uses CMOS LSI in the integral part of the
circuits. When handling these parts, the following
precautions should be strictly followed. CMOS LSI
have extremely high impedance at its input and output
terminals. For this reason, it is easily influenced by the
surrounding high voltage power source, static electricity
charge in clothes, etc. and sometimes it is not fully
protected by the built-in protection circuit.
In order to protect CMOS LSI.
1. When storing and transporting, thoroughly wrap them
in aluminium foil. Also wrap all PW boards containing
them in aluminium foil.
2. When soldering, ground the technician as shown in
the figure and use grounded soldering iron and work
table.
