2. After adjustment, check the following.
1. In and out play of door remains less than 0.5mm when in 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 door sensing switch and secondary interlock switch interrupt
the circuit before the door can be opened.
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 Micro-
wave Measurement Procedure.)

1. REMOVAL
1. Disconnect oven from power supply.
2. Push the open button and open the door slightly.
3. Insert a putty knife (thickness of about 0.5mm) into the gap
between the choke cover and door frame as shown in Figure C-4 to
free engaging parts.
4. Pry the choke cover by inserting a putty knife as shown Figure C-4.
5. Release choke cover from door panel.
6. Now choke cover is free.
NOTE:
When carrying out any repair to the door, do not bend or
warp the slit choke (tabs on the door panel assembly) to
prevent microwave leakage.

7. Slide latch head upward and remove it from door frame with releas-
ing latch spring from door frame and latch head.
8. Now, latch head and latch spring are free.
9. Release door panel from tweleve (12) tabs of door frame.
10.Now, door panel with sealer film is free.
11.Tear sealer film from door panel.
12.Now, door panel is free.
13.Remove door screen from door frame.
14.Now, door screen is free.
2. REINSTALLATION
1. Reinstall door screen to door frame.
2. Put sealer film on door panel. Refer to “Sealer Film” about how to
handle new one.
3. Reinstall door panel to door frame by fitting tweleve (12) tabs of
door frame to tweleve (12) holes of door panel.
4. Reinstall the latch spring to the latch head. Reinstall the latch
spring to the door frame. Reinstall latch head to door frame.
5. Catch two (2) pins of door panel on two (2) hole of upper and lower
oven hinges as shown Figure C-5.
6. Reinstall choke cover to door panel by pushing
NOTE:
After any service to the door;
1)
Make sure that door sensing switch and secondary interlock
switch are operating properly. (Refer to chapter “Test Proce-
dures”.).
2)
An approved microwave survey meter should be used to
assure compliance with proper microwave radiation emission
limitation standards.
3. 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 micro-
wave survey meter. (Refer to Microwave Measurement Procedure.)
NOTE:
The door on a microwave oven is designed to act as an
electronic seal preventing the leakage of microwave
energy from oven cavity during cook cycle. This function
does not require that door be air-tight, moisture (conden-
sation)-tight or light-tight. Therefore, occasional appear-
ance of moisture, light or sensing of gentle warm air
movement around oven door is not abnormal and do not
of themselves indicate a leakage of microwave energy
from oven cavity.
