Door disassembly

1. Remove door C from door E by carefully pulling outward

starting from upper right hand corner using a flat blade
screwdriver.

2. Remove 4 screws holding door E to door A assembly to

separate door E from door A.

3. Remove door key and door key spring.
After replacement of the defective component parts of the
door, reassemble it and follow the instructions below for
proper installation and adjustment so as to prevent an
excessive microwave leakage.
1. When mounting the door to the oven, be sure to adjust the

door parallel to the bottom line of the oven face plate by
moving the upper hinge and lower hinge in the direction
necessary for proper alignment.

2. Adjust so that the door has no play between the inner door

surface and oven front surface. If the door assembly is not
mounted properly, microwave power may leak from the
clearance between the door and oven.

3. Perform the microwave leakage test.

Turntable motor

1. Remove the motor cover by breaking off at the 8 spots

indicated by arrows. (See Figure)

NOTE: After breaking off the motor cover, make sure that

cut-off portions are properly trimmed off or bend to
inside so that no sharp edge will expose to outside.

2. Disconnect 2 lead wires connected to the turntable motor.
3. Remove the turntable motor by removing 2 screws.
NOTE: To reinstall the motor cover, use 4x6 screw.
