NOTE: After any service to the door;

ary interlock switch are operating properly. (Re-

fer to chapter "Test Procedures".).

(B) An approved microwave survey meter should be

used to assure compliance with proper micro-

wave radiation emission limitation standards.

(Refer to Microwave Measurement Procedure.)

After any service, make sure of the following :

1. Door latch heads smoothly catch latch hook through

latch holes and that latch head goes through center of

latch hole.

2. Deviation of door alignment from horizontal line of

cavity face plate is to be less than 1.0mm.

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 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.
