1. Disconnect the power supply cord, and then remove
outer case.
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
If the door sensing switch, secondary interlock switch and
monitor switch do not operate properly due to a
misadjustment, the following adjustment should be made.
4. Loosen the two (2) screws holding latch hook to the oven
cavity front flange.
5. With door closed, adjust latch hook by moving it back and
forth, and up and down. In and out play of the door
allowed by the upper and lower position of the latch hook
should be less than 0.5mm. The vertical position of the
latch hook should be adjusted so that the door sensing
switch and secondary interlock switch are activated with
the door closed. The horizontal position of the latch hook
should be adjusted so that the plunger of the monitor
switch is pressed with the door closed.
6. Secure the screws with washers firmly.
7. Check the operation of all switches. If each switch has
not activated with the door closed, loosen screw and
adjust the latch hook position.
After adjustment, check the following.
1. In and out play of door remains less than 0.5mm when in
DOOR SENSING SWITCH/SECONDARY INTERLOCK SWITCH AND MONITOR SWITCH ADJUSTMENT
the latched position. First check upper position of latch
hook, pushing and pulling upper portion of door toward
the oven face. Then check lower portion of the latch
hook, pushing and pulling lower portion of the door
toward the oven face. Both results (play in the door)
should be less than 0.5mm.
2. The contacts of door sensing switch and secondary
interlock switch open within 1.6mm gap between right
side of cavity face plate and door when door is open.
3. Monitor switch contacts close when door is opened.
4. Re-install outer case and check for microwave leakage
around door with an approved microwave survey meter.
(Refer to Microwave Measurement Procedure.)

REMOVAL
1. Disconnect the power supply cord and then remove the
outer case.
2. Open the door slightly.
3. To discharge high voltage capacitor, wait for 60 seconds.
4. Disconnect the wire harness from the power unit on the
base plate.
5. Insert a putty knife (thickness of about 0.5mm) into the
gap between the choke cover and door frame as shown
in Figure C-6 to free engaging parts.
6. Pry the choke cover by inserting a putty knife as shown
Figure C-6.
7. Release choke cover from door panel.
8. Now choke cover is free.

9. Release two (2) pins of door panel from two (2) holes of
upper and lower oven hinges by lifting up.
10.When pulling out the wire harness from the hole of the
oven cavity front plate and the front leg. Remove the door
from the oven cavity.

11.Now, the door is free from the oven cavity.
REINSTALLATION
1. Insert the wire harness to the holes of the front leg and
the oven cavity front plate.
2. Catch two (2) pins of door panel on two (2) hole of upper
and lower oven hinges.
3. Re-install choke cover to door panel by pushing.
4. Connect the wire harness to the power unit on the base
plate.
5. Now the door is installed.
Note: After any service to the door;
(A) Make sure that door sensing switch and secondary
interlock switch are operating properly. (Refer to
chapter “Test Procedures”.).
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
After any service, make sure of the following :
1. Door latch heads smoothly catch latch hook through
latch holes and that latch head goes through center of
latch hole.
2. Deviation of door alignment from horizontal line of cavity
face plate is to be less than 1.0mm.
3. Door is positioned with its face pressed toward cavity
face plate.
4. Check for microwave leakage around door with an
approved microwave survey meter. (Refer to Microwave
Measurement Procedure.)
