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.
