1. Door latch heads smoothly catch latch hook through
latch holes and that latch head goes through center of

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 in themselves indicate a leakage
of microwave energy from oven cavity.
