D. DOOR GROSS ASSEMBLY REMOVAL
1) Open the door.
2) Remove the choke cover cap very carefully with a

3) Lift up and push the door.
NOTE:
1. After replacing the door, be sure to check that the
primary switch, monitor switch, and secondary
switch operate normally.
2. After replacing the door, check for microwave
energy leakage with a survey meter. Microwave
energy must be below the limit of 5 mW/cm
a 275 ml water load)
3. When mounting the door assembly to the oven
assembly, be sure to adjust the door assembly
parallel to the chassis. Also adjust so the door has
no play between the inner door surface and oven
frame assembly. If the door assembly is not
mounted properly, microwaves may leak from the
clearance between the door and the oven.
