latch holes and that latch head goes through center of

4. Check for microwave leakage around door with an

approved microwave survey meter. (Refer to Micro-
wave Measurement Procedure.)

Note: The door on a microwave oven is designed to act as

an electronic seal preventing the leakage of micro-
wave energy from oven cavity during cook cycle.
This function does not require that the 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.
