4-3-4 Removal of Key Door & Spring

Samsung Electronics

4-3

1. Detach spring from Door "E" and key door.
2. 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.

3. 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.

4. 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 energy may leak from the space
between the door and oven.

5. Do the microwave leakage test.

1. Disconnect the oven from the power source.

2. Remove the 10A fuse in the Noise filter.

3. When replacing the 10A fuse, be sure to use an

exact replacement part. If new 10A fuse blows
out again after replacement, check the primary
interlock switch, Secondary switch and interlock
monitor switch.

4. When the above three switches operate properly,

check if any other part such as the control circuit
board, blower motor or high voltage
transformer is defective.

1. Take out the glass tray and guide roller from  the

cavity.

2. Turn the oven upside down to replace the drive motor.

3. Remove a screw securing the drive motor cover.

4. Disconnect all the lead wires from the drive motor.

5. Remove screws securing the drive motor to the

cavity.

6. Remove the drive motor and coupler.

7. When replacing the drive motor, be sure to

remount it in the correct position with the
coupler.

8. Connect all the leads to the drive motor.

9. Screw the drive motor cover to the base plate

with a screw driver.
