WHEN REPLACING ANY DOOR MICROSWITCH,
REPLACE ONLY WITH THE SAME SWITCH SPECI-
FIED ON THE PARTS LIST.
D. REMOVING FUSE
Remove the 8 A fuse with screwdriver.
NOTES
- When replacing the 8 A fuse, be sure to use the exact
repair part.
- If the 8 A fuse blows immediately, check the primary
and secondary interlock switch, the relays RL-4 and
RL-1 (on the control circuit board) and the interlock
monitor switch according to “CHECKOUT PROCE-
DURE FOR SWITCHES” on page 7 .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-4 and RL-1 or the interlock monitor switch
is adjusted or replaced.
- If the interlock switch, the relay RL-4 and RL-1 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 cabinet(frame).
(2) Remove 2 screws securing the P.C.B for Power
with bracket to the cavity. (Figure 11)
Then take out it.
(3) To remove the Control Assembly, remove the
all connector and lead wires from the Control
circuit board.
(4) Remove 3 screws securing the Control
Assebmbly to the cavity.
(5) Remove the FPC connector from the connector
S101 while pushing up the end of the plastic
fastner .
(5) Remove 6 screws securing the control circuit
board.
C.REMOVING DOOR SENSING SWITCH
(See Figure on page 1)
(1) Disconnect all lead wires from the door sens-
ing switch and door interlock switch.
(2) Remove 2 screw securing the lever stopper.
(3) Pull out the door sensing switch toward you
while pressing switch stopper together with
door interlock switch.
(4) Make the necessary adjustments or replace-
ment of the switch by reversing step (3) 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 7.
G. REMOVING MAGNETRONS
F.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.
(See Figure 12)
(1) Remove the Cabinet.
(2) Remove all lead wires from magnetron and
thermal limiter on duct.
(3) Remove 2 screws securing the stay plate.
(4) Remove 4 screw securing magnetrons to the
waveguide.
(5) Remove magneron fromthe wave guide
VERY CAREFULLY.
NOTES
- When removing the magnetron, make sure that its
dome does not hit any adjacent parts, or it may be
damaged.
- When replacing the magnetron, be sure to install the
magnetron gasket in the correct position and be sure
that the gasket is in good condition.
- After replacing the magnetron, check the microwave
energy leakage to ensure it is below the limit of
5mW/cm
2
.
(6) Lift up the control circuit board from its
left side and take out from the control base.
