latch holes and that latch head goes through center of

latch hole.

3. Door is positioned with its face pressed toward cavity

face plate.

4. 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.
