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 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 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.

REMOVAL
1. Disconnect the power supply cord.
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60 seconds.
4. Remove the antenna motor from the oven cavity bottom plate,

referring to "ANTENNA MOTOR REMOVAL" .
