7. Re-install choke cover to door panel by pushing.
NOTE: After any service to the door;
1) Make sure that secondary interlock switch, door sensing
switch and monitor switch are operating properly. (Refer to
chapter "Test Procedures".).
2) An approved microwave survey meter should be used to
assure compliance with proper microwave radiation emission
limitation standards.
3. 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 micro-
wave 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 oven cavity during cook cycle. This function
does not require that door be air-tight, moisture (conden-
sation)-tight or light-tight. Therefore, occasional appear-
ance 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.
