C.REMOVING LATCH INTERLOCK SWITCH
(See Figure on page 1)
(1) Disconnect all lead wires from the latch
interlock switch .
(2) Remove 2 screw securing the lever stopper.
(3) Remove 2 screws and nuts from the switch.
(4) Make the necessary adjustments or replace-
ment of the switch by reversing step (2) and
check microwave energy leakage according to
" 1 . A D J U S T M E N T P R O C E D U R E F O R
SWITCHES" on page 1. Check proper opera-
tion according to "CHECKOUT PROCEDURE
FOR SWITCHES" on page 6.
WHEN REPLACING ANY DOOR MICROSWITCH,
REPLACE ONLY WITH THE SAME SWITCH SPECI-
FIED ON THE PARTS LIST.
D. REMOVING FUSE
Remove the 10A fuse with screwdriver.
NOTES
- When replacing the 10A fuse, be sure to use the
exact repair part.
- If the 10A fuse blows immediately, check the primary
and secondary interlock switch, the relays RL-3 and
RL-5 (on the control circuit board) and the interlock
monitor switch according to "CHECKOUT PROCE-
DURE FOR SWITCHES" on page 6. Make sure to check
the microwave energy leakage according to "1. AD-
JUSTMENT PROCEDURE FOR SWITCHES" on page
1, when the primary and secondary interlock switches,
the relay RL-3 and RL-5 or the interlock monitor switch
is adjusted or replaced.
- If the interlock switch, the relay RL-3 and RL-5 or the
interlock monitor switch operate properly, determine
which of the following is defective : control circuit board,
high voltage transformer, high voltage capacitor, high
voltage diode or magnetron.
E. REMOVING CONTROL CIRCUIT BOARD
(1) Remove the all connector and lead wires from
the Control panelcontrol circuit board.
(2) Remove 3 screws to detach the control panel
complete the oven cavity.
(3) Remove the FPC connector from the connector
S101 while pushing up the end of the plastic
fastner .
(4) Remove 6 screws securing the control circuit
board.
(5) Lift up the cpontrol circuit board from its left
side and take out from the control base.
G.REMOVING TOUCH KEY BOARD
(1) Remove the FPC connector from the connector
S101 while pushing up the end of the plastic fastner.
(2) Remove the control plate which is held on the
control base with the adhesive tape from the front
of control base.
H.REMOVING TIME CONTROLLER
After removing control circuit board;
(1) Pull out the control knob.
(2) Remove 6 screws securing the control frame.
(3) Remove a hex. nut securing the time controller
to the control base.
I. REMOVING MAGNETRONS
(See Figure 11)
1. When removing Magnetron of the rear side;
(1) Remove all lead wires from blower motor, magne
tron and thermal limiter on magnetron.
(2) Remove the exhast duct on the rear cavity by
loosing 4 screws to detach 1 screw securing the
stay.
(3) Remove the stay by removing screw securing 2
magnetrons, front and rear cavity and 2 blower
motor assembly.
(4) Remove 2 screw securing the rear side duct.
(6) Remove magneron with blower assembly from
the wave guide VERY CAREFULLY.
2. When removing Magnetron of the front side;
Take front side magnetron off after removing
magnetron of the rear side.
(1) Remove all lead wires from blower motor, magne
tron and thermal limiter on magnetron.
(2)Remove the exhast duct on the rear cavity by
loosing 4 screws to detach 1 screw securing the
stay.
(3) Remove the stay by removing screw securing 2
magnetrons, front and rear cavity and 2 blower
motor assembly.
(4) Remove 1 screw securing the front side duct.
(5) Remove 4 hex. nuts securing the front side
magnetron to the wave guide.
(6) Remove magneron with blower assembly from
the wave guide VERY CAREFULLY.
