Note: After any service to the door;
(A) Make sure that the monitor switch,
monitored latch switch and stop 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.
(Refer to Microwave Measurement
Procedure.)
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 centre 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.)
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.
