plate and door when door is open.

3. Monitor switch contacts close when door is opened.
4. The contacts of 2nd. latch switch open when the door

is open.

5. Re-install outer case and check for microwave leakage

around door with an approved microwave survey meter.
(Refer to Microwave Measurement Procedure.)

REMOVAL
1. CARRY OUT 3D CHECKS.
2. Remove outer case.
3. Disconnect the 12-pin wire harness from the power

unit on the base plate.

4. Insert a putty knife (thickness of about 0.5mm) into the

gap between the choke cover and door frame as shown

Note: After any service to the door;

(A) Make sure that 1st. latch switch, 2nd. latch switch,

stop switch and monitor switch. (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.

DOOR REPLACEMENT

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.
