6. Secure the screws with washers firmly.
After adjustment, check the following.
1. In and out play of door remains less than 0.5mm at the
latched position.
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 Microwave Measurement Procedure.)
REMOVAL
1. Disconnect the power supply cord and then remove
outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Remove turntable tray and turntable support from oven
cavity.
5. Remove three (3) screws holding lower oven hinge.
6. Remove the lower oven hinge from oven cavity bottom
flange.
7. Remove door assembly from upper oven hinge on the
oven.
8. Door assembly is now free.
Note: When the individual parts are replaced, refer to
"Door Disassembly".
9. On re-installing door, insert the upper oven hinge into the
door hinge pin. Then while holding door in place.
10.Make sure the door is parallel with oven face lines (left
and upper side lines) and door latch heads pass through
latch holes correctly.
11.Insert the lower oven hinge into oven cavity bottom
flange and then engaged the door hinge pin. Then
secure the lower oven hinge firmly with tree (3) mounting
screws.
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.
DOOR ADJUSTMENT
The door can be adjusted by keeping screws of each hinge
loose.
After adjustment, 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. Re-install outer case and check for microwave leakage
around door with an approved microwave 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
airtight, moisture (condensation)-tight or light-tight.
Therefore, occasional appearance 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. If such were the case, your oven could not
be equipped with a vent, the very purpose of which
is to exhaust the vapor-laden air from the oven
cavity.
