1. CARRY OUT 3D CHECKS.

2. Remove the two (2) screws holding each of the upper and lower

oven hinges to the oven cavity.

3. Remove door assembly with upper and lower oven hinges by pull-

ing it forward.

4. Release upper and lower oven hinges from door assembly.

5. Now, door assembly is free.

NOTE: When individual parts are replaced, refer to “Door Disassem-

bly”.

1. Insert the upper and lower oven hinges into door hinge pins.

2. Insert the upper and lower oven hinges with door assembly into

rectangular holes of oven cavity front plate.

3. Make sure that the door is parallel with oven face lines (left and

upper side line) and door latch heads pass through the latch holes
correctly.

4. Fasten upper and lower oven hinges firmly to oven cavity with two

(2) screws on each hinge. 

NOTE: After any service to the door;

1) Make sure that interlock switches, stop switch and monitor

switches are operating properly. (Refer to chapter “Test
Procedures”.). 

2) An approved microwave survey meter should be used to

assure compliance with proper microwave radiation emis-
sion limitation standards.

When removing and/or loosening hinges such as in door replacement,
the following adjustment criteria are taken. Door adjustment is per-
formed with the door properly installed and closed and while the oven
hinges are loose.

1. Loosen upper and lower oven hinges with phillips head screw

driver.

2. Adjust the door by moving it vertically so that the top right hand cor-

ner of the door is in line with the top of the control panel frame
assembly.

3. Tighten the upper and lower oven hinge screws. 

1. Door latch heads smoothly catch the latch hook through the latch

holes, and the latch head goes through the center of the latch hole.

2. Deviation of the door alignment from horizontal line of cavity face

plate is to be less than 1.0mm.

3. The door is positioned with its face depressed toward the cavity

face plate.

4. Re-install outer case and check for microwave leakage around

door with an approved microwave survey meter. (Refer to Micro-
wave Measurement Procedure.)

NOTE: The door on a microwave oven is designed to act as an elec-

tronic seal preventing the leakage of microwave energy from
oven cavity during cook cycle. This function does not require
that door be air-tight, 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.

Figure C-6. Door Replacement

1. Open the door and insert a putty knife (thickness of about 0.5mm)

in gap between the choke cover and corner portion of door panel to
free engaging parts. Refer to Fig. C-7.

NOTE: As the choke cover and door panel are engage at 16 places,

do not force any particular part.

2. Remove the choke cover carefully. (If choke cover is broken,

replace with a new one.)
