C. DOOR GROSS ASSEMBLY REMOVAL
(1) Open the door.
(2) Remove the choke cover cap very carefully with a flat-blade
screwdriver.
CAUTION : Be careful not to damage door seal plate by
screwdriver.
(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.sq. (with 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.
