8. Lift up the door assembly to release the upper and lower door
hinge pins from the upper and lower oven hinges.
9. Now, the door assembly is free.
NOTE: When the individual parts are replaced, refer to “Door Disas-
sembly”.
2. REINSTALL
1. On re-installing 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. Re-install the door stopper to the door assembly.
7. Re-install the hood louver to
the oven cavity front face plate.
NOTE:
After any service to the door;
1)
Make sure that door sensing switch and secondary
interlock switch are operating properly. (Refer to chap-
ter “Test Procedures”.).
2)
An approved microwave survey meter should be used
to assure compliance with proper microwave radiation
emission limitation standards.
3. 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. Re-install outer case and check for microwave leakage around
door with an approved microwave su
rvey meter. (Refer to Micro-
wave 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.
