[8] DOOR SENSING SWITCH, SECONDARY INTERLOCK SWITCH AND MONITOR SWITCH
ADJUSTMENT
1. Adjustment
If the door sensing switch, secondary interlock switch and monitor
switch do not operate properly due to a misadjustment, the following
adjustment should be made.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
REMOVAL”.
3. Open the oven door and block it open.
4. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
5. Loosen two (2) screws holding the latch base angle to the oven
cavity front plate.
6. With door closed, adjust the latch base angle by moving them back
and forth, and up and down. In and out play of the door allowed by
the latch base angle should be less than 0.5 mm.
The position of the latch base angle should be adjusted so that the
plungers of the door sensing switch, the secondary interlock switch
and the monitor switch are pushed with the door closed.
7. Secure the screws firmly.
8. Check all of the switches operation. If each switch plunger has not
been pushed with the door closed, loosen the screws and adjust
the position of the latch base angle.
2. After adjustment, check the following.
1. In and out play of the door remains less than 0.5 mm when in the
latched position. First check the position of the latch base angle
pushing and pulling right portion of the door toward the oven face.
Then check the position of the latch base angle, pushing and pull-
ing left portion of the door toward the oven face. Both results (play
in the door) should be less than 0.5 mm.
2. The door sensing switch and the secondary interlock switch open
within 3.0mm gap between the oven door and cavity face.
3. The monitor switch contacts (NC and COM) close when the door is
opened.
4. Reinstall the outer case cabinet and check for microwave leakage
around the door with an approved microwave survey meter. (Refer
to Microwave Measurement Procedure.)
[9] BOTTOM PLATE ASSEMBLY REMOVAL
Before the control unit, noise filter unit, inverter unit, fan motor and
magnetron are replaced, removal of the bottom plate is required.
1. Disconnect the power supply cord, and then remove the outer case
and the back plate assembly.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
4. Disconnect the high voltage wire from the magnetron terminal with
insulated pliers.
5. Make the terminal (metal part) of the high voltage wire contact to
the magnetron body with insulated pliers.
6. Now, the capacitors of the inverter unit are discharged.
WARNING:
Use the pliers that the portions of their handles are
insulated completely to avoid an electric shock.
7. Pull the reservoir (feed reservoir assembly) out of the set.
8. Remove the dew tray and drain accumulated water from the tray.
9. Disconnect the wire leads from the convection motor, the thermal
cut-out (convection) and the thermal cut-out (Fan).
10.Remove the motor angle from the filter cover by removing the one
(1) screw and releasing the one (1) tab.
11.In order to remove the bottom plate assembly, turn over the unit.
NOTE:
When turning over the unit, first place its left or right side
down and then the top side down (otherwise, the convec-
tion motor and/or convection duct will be damaged).
12.Remove the nine (9) screws fixing the bottom plate assembly (bot-
tom face) to the left heat shield plate, the right heat shield plate, the
left hinge assembly, the right hinge assembly and the front plate of
the oven.
13.Place the oven right side down. And open the bottom plate assem-
bly from the oven.
14.Disconnect the two (2) blue connectors from the blue connectors of
the control harness and the main harness which are installed in the
heat cover R assembly.
15.Take the snap bands tying the harnesses out of the hole of the bot-
tom plate.
16.Lift the bottom plate assembly to remove it from the oven body.
NOTE:
In order to prevent the fan duct covering around the mag-
netron terminal from hitting the terminal, slightly shift the
bottom plate assembly toward the left hinge assembly
and then lift the bottom plate assembly.
[10] ENGINE UNIT REMOVAL
1. ENGINE UNIT REMOVAL
1. Disconnect the power supply cord, and then remove the outer case
and the back plate assembly.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
4. Disconnect the high voltage wire from the magnetron terminal with
insulated pliers.
5. Make the terminal (metal part) of the high voltage wire contact to
the magnetron body with insulated pliers.
