Door Disassembly - Sharp R-8000G Service Manual

Door adjustment
When removing and/or loosening the oven hinges such as in door
replacement, the following adjustment criteria are taken.
Door adjustment is performed with the door properly installed and
closed and while the oven hinges are loose.
1. Loosen the screws holding the oven hinge right and the oven
hinge left to the bottom plate with screwdriver.
2. Adjust the door by moving it so that the door is parallel with the
oven cavity front plate lines (right and left side lines) and the
door latch heads pass through the latch holes correctly.
3. Tighten the screws holding the oven hinge right and the oven
hinge left to the bottom plate.
After adjustment, make sure of the following:
1. The door latch heads smoothly catch the latch hooks through
latch holes and the latch heads goes through center of latch
holes.
2. The door is positioned with its face pressed toward oven cavity
front plate.
3. Reinstall the outer case cabinet and check for microwave
leakage around the 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 the oven cavity during cook cycle. This
function does not require that the door be airtight, moisture
(condensation)-tight or light-tight. Therefore, occasional
appearance of moisture, light or sensing of gentle warm
air movement around the oven door is not abnormal and
do not of themselves indicate a leakage of microwave
energy from the oven cavity. If such were the case, your
oven could not be equipped with a vent, the very purpose
of which is exhaust the vapor-laden air from the oven
cavity.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to "OUTER CASE
CABINET REMOVAL".
3. Open the oven door and block it open.
4. Discharge the high voltage capacitor.
5. Remove the door assembly, referring to "Door Replacement".
6. Place the door assembly on a soft cloth with latch heads facing
up.
NOTE: As the engaging parts of the choke cover and the door
panel assembly are provided at 16 places, do not force
any particular part.
7. Replacement of the door components are as follows:
CHOKE COVER
8. Insert a putty knife (thickness of about 0.5 mm) into the gap
between the choke cover and the door panel assembly as
shown in Figure C-8.
9. Lift up the choke cover.
10. Now, the choke cover is free from the door panel assembly.
NOTE: When carrying out any repair to the door, do not bend or
wrap the slit choke (tabs on the door panel assembly) to
prevent microwave leakage.
