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 monitored latch switch, latch 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.)

[13] DOOR REPLACEMENT
1. REMOVAL
1. Disconnect the power supply cord.
2. Open the door slightly.
3. Insert a putty knife (thickness of about 0.5mm) into the gap
between the choke cover and corner portion of door panel as
shown in Figure C-5 to free engaging parts.
ure C-5.
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.
Figure C-5. Door Disassembly
7. Release two (2) pins of door panel from two (2) holes of upper and
lower oven hinges by lifting up.
8. Now, door panel is free from oven cavity.
9. Release door panel from ten (10) tabs of door frame and remove
door frame by sliding the door panel downward.
12.Now, door panel is free.
13.Slide latch head upward and remove it from door frame with releas-
ing latch spring from door frame and latch head.
14.Now, latch head and latch spring are free.
15.Remove door screen from door frame.
16.Now, door screen is free.
2. REINSTALLATION
1. Re-install door screen to door frame.
2. Re-install latch spring to the head. Re-install latch spring to the
door frame. Re-install latch head to the door frame.
5. Catch two (2) pins of door panel on two (2) hole of upper and lower
oven hinges.
6. Re-install choke cover to door panel by pushing.
NOTE:
After any service to the door;
1)
Make sure that monitored latch switch, latch switch and moni-
tor switch are operating properly. (Refer to chapter “Test Pro-
cedures”.).
2)
An approved microwave survey meter should be used to
assure compliance with proper micro-wave 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 Micro-wave Measurement Proce-
dure.)
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.
