After adjustment, make sure of the following:
1. Door latch heads smoothly catch the latch hook through the
latch holes, and the latch head goes through the center of
the latch hole.
2. Deviation of the door alignment from horizontal line of cavity
face plate is to be less than 1.0mm.
3. The door is positioned with its face depressed toward the
cavity face plate.
4. Re-install outer case and 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. If such were
the case, your oven could not be equipped with a
vent, the very purpose of which is to exhaust the
vapor-laden air from the oven cavity.
