NOTE: 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 airtight, 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 an do not of themselves, indicate a leakage of
microwave energy from oven cavity. If such were the
case, the oven could not be equipped with a vent, the
very purpose of which is to exhaust vapor-laden air
