Note: After any service to the door;
(A) Make sure that 1st. latch switch, 2nd. interlock relay
control switch and monitor switch are operating
properly. (Refer to chapter “Test Procedures”.).
(B) An approved microwave survey meter should be used
to assure compliance with proper microwave radiation
emission limitation standards.
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 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.
