4. The hinge screws should then be tightened to hold the
door in place, and the feeler gauges removed.
5. The door gap should then be checked again using feeler
gauges.
Below is a table giving the door setting for the:-
EM-G4750
After setting the door gap, the door is closed with the door
latch fully engaged and the screws securing the switch
base are loosened. The switch base is then eased to the
right to pull the door face hard onto the front of the
microwave. The screws are then secured tight. To check if
the operation has been carried out correctly push the door
top and bottom. Any movement should be minimal, and
the door should feel tight to the front face of the
microwave.Confirm that the operation has been success-
fully carried out by depressing the door release lever until
the microswitches are heard to operate. This occurs just
before the door opens.
NOTES
- After replacing the door, be sure to check that the
primary interlock switch, door sensing switch and the
interlock monitor switch operate normally. (See
page 1).
- After replacing the door check for microwave energy
leakage with a leakage detector.
Microwave energy leakage must be below the limit of
5mW/cm

F. DISASSEMBLYING DOOR
( See exploded view on page 18 )
(1) Insert a thin flat blade screwdriver between the
choke dielectric and the door mainframe and lift

When re-installing them, replace them with new ones
if they are damaged.
- After installing the door in place, check for microwave
energy leakage with a leakage detector.
Microwave energy leakage must be below the limit of
5mW/cm

0.2mm.
0.8mm.
(3) Remove power cord from cavity assembly by
lifting cord bush, moving it to the left and pulling it
away from cavity rear plate.
(4) Install the new power supply cord with the
reverse procedure of above (1) to (3).
WARNING
For changing the power supply cord, never use parts

H. REMOVING TURNTABLE MOTOR COVER
(Refer to Figures 13 and 14 below )
(1) Turn the unit and cut the 6 joints of the bottom
plate and the motor cover using diagonal pliers
(nipper). (See Figure 13 )
(2) Seperate the motor cover and the bottom plate.
NOTES
- Bend the cut joints inside slightly for safety and be
careful of the sharp edges.
RE-INSTALL :
(1) Rotate the motor cover through 180˚.
(2) Insert the edge of the motor cover into the tab on
the bottom plate.
(3) Secure the motor cover by screwing it to the
bottom plate (See Figure 14 )
Clip metal here
and at other 5
locations.
