DOOR ASSEMBLY REMOVAL
1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Disconnect the 9-pin wire harness from the power unit.
5. Release a snap band of the 9-pin wire harness from the
hole on the base plate R.
6. Remove the two (2) screws holding the bottom sash to
the oven cavity front face plate.
7. Remove the bottom sash with 9-pin wire harness from the
oven cavity front face plate. And remove the connecter
of the 9-pin wire harness from the long hole of the oven
cavity front face plate.
8. Remove the 9-pin wire harness from the bottom sash.
9. Insert a putty knife (thickness of about 0.5mm) into the
gap
A
between the upper door stopper and the choke
cover as shown in Figure C-4 to free engaging parts.
10.Lift up the upper door stopper.
11.Remove the lower door stopper from the door assembly
in a similar way which the upper door stopper is removed.
12.Now, the upper and lower door stoppers are free from
the door assembly.
13.Lift up the door assembly to release the upper and lower
door hinge pins from the upper and lower oven hinges.
14.Now, the door assembly is free.
Note: When the individual parts are replaced, refer to
"Door Disassembly".
DOOR ASSEMBLY REINSTALL
1. On reinstalling door, insert the lower oven hinge to lower
door hinge pin.
2. Insert the upper oven hinge to the upper door hinge pin.
3. Shut the door (close the contacts of interlock switches).
4. Make sure upper and lower oven hinges are inserted into
the upper an lower door hinge pins.
5. Make sure the door is parallel with oven face lines (left
and upper side lines) and door latch heads pass through
latch holes correctly.
6. Reinstall the upper and lower door stoppers to the door
assembly.
7. Reinstall the 9-pin wire harness into the bottom sash.
The 9-pin wire harness should be held by three (3) tabs
on the bottom sash. And the marking portion on the 9-
pin wire harness should be held by left tab as shown in
Figure C-3.
8. Insert the connector of the 9-pin wire harness into the
long hole of the oven cavity front face plate. And reinstall
the bottom sash to the oven cavity front face plate with
the two (2) screws.
9. Reconnect the 9-pin wire harness to the power unit.
10. Insert the snap band of the 9-pin wire harness into the
hole on the base plate R.
Note: After any service to the door;
(A) Make sure that door sensing switch and primary
interlock switch are operating properly. (Refer to
DOOR REPLACEMENT
chapter "Test Procedures".)
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
After any servicing, 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. Reinstall 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 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.
