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 (condensation)-tight or light-tight. Therefore,
occasional appearance 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.

and lower oven hinges.
7. Re-install choke cover to door panel by pushing.
Note:
After any service to the door;
A)
Make sure that door sensing switch and primary
interlock switch are operating properly. (Refer to
chapter “Test Procedures”.).
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
After any service, 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. Check for microwave leakage around door with an approved
microwave survey meter. (Refer to Microwave
Measurement Procedure.)
