HIGH VOLTAGE CAPACITOR, HIGH VOLTAGE FUSE AND
HIGH VOLTAGE RECTIFIER ASSEMBLY REMOVAL
To remove the components, proceed as follows.
1. CARRY OUT 3D CHECKS.
2. Disconnect H.V. wire of the high voltage rectifier as-
sembly from the magnetron.
3. Disconnect the filament lead of the high voltage trans-
former from the high voltage capacitor.
4. Remove one (1) screw holding earth side terminal of
the high voltage rectifier assembly.
5. Disconnect high voltage fuse and terminal of high
voltage rectifier assembly from the high voltage ca-
pacitor.
6. Now, the high voltage rectifier assembly should be free.
7. Disconnect the high voltage fuse from the high voltage
transformer.
8. Now, the high voltage fuse is free.
9. Remove one (1) screw holding the capacitor holder to
the oven cavity rear plate.
10.Remove one (1) screw holding the fan duct to the oven
cavity rear plate.
11.Release the capacitor holder from the fan duct.
12.Remove the capacitor from the capacitor holder.
13.Now, the capacitor should be free.
CAUTION: WHEN REPLACING HIGH VOLTAGE
RECTIFIER ASSEMBLY, ENSURE THAT
THE CATHODE (EARTH) CONNECTION
IS SECURELY FIXED TO THE CAPACI-
TOR HOLDER AND OVEN CAVITY REAR
PLATE WITH AN EARTHING SCREW.
1. CARRY OUT 3D CHECKS.
2. Disconnect the high voltage wire of the high voltage
rectifier assembly and filament lead of the transformer
from the magnetron.
3. Remove the one (1) screw holding the air guide to the
magnetron and remove the air guide.
4. Remove the one (1) screw holding the chassis support
to the magnetron.
5. Carefully remove four (4) screws holding magnetron to
MAGNETRON REMOVAL
waveguide, when removing the screws hold the mag-
netron to prevent it from falling.
6. Remove the magnetron from the waveguide with care
so the magnetron antenna is not hit by any metal object
around the antenna.
CAUTION: WHEN REPLACING THE MAGNETRON,
BE SURE THE R.F. GASKET IS IN PLACE
AND THE MAGNETRON MOUNTING
SCREWS ARE TIGHTENED SECURELY.
CONTROL PANEL ASSEMBLY
1. CARRY OUT 3D CHECKS.
2. Disconnect the main wire harness from the control unit.
3. Remove the one (1) screw holding the control panel
assembly to the oven cavity front plate.
4. Lift up the control panel assembly.
5. Now, the control panel assembly is free.
CONTROL UNIT
6. Disconnect the flat ribbon cable from the connector CN-G.
7. Remove the six (6) screws holding the control unit to
the control panel frame.
8. Release the two (2) tabs of the control panel frame
holding the control unit to the control panel frame.
CONTROL PANEL ASSEMBLY REMOVAL
9. Now, the control unit is free.
NOTE: 1. Before attaching a new key unit, wipe off re-
maining adhesive on the control panel frame
surfaces completely with a soft cloth soaked in
alcohol.
2. When attaching the key unit to the control panel
frame, adjust the upper edge and right edge of
the key unit to the correct position of control
panel frame.
3. Stick the key unit firmly to the control panel
frame by rubbing with a soft cloth so not to
cause scratches.
1. CARRY OUT 3D CHECKS.
2. Screw the oven lamp from the oven lamp socket off.
3. Now, the oven lamp is free.
4. Lift up the oven lamp socket from air intake duct.
5. Pull the wire leads from the oven lamp socket by
pushing the terminal hole of the oven lamp socket with
the small flat type screw driver.
6. Now, the oven lamp socket is free.
