[3] HIGH VOLTAGE COMPONENTS REMOVAL
(HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY)
To remove the components, proceed as follows.
1. CARRY OUT 3D CHECKS.
2. Disconnect the filament lead of the high voltage transformer and
the high voltage transformer secondary wire from the high voltage
capacitor.
capacitor.
3. Remove one (1) screw holding the capacitor holder to the bottom
plate.
4. Remove the high voltage capacitor with the capacitor band from the
bottom plate.
5. Remove one (1) screw holding earth side terminal of the high volt-
age rectifier assembly.
6. Remove the capacitor holder from the high voltage capacitor.
7. Disconnect the high voltage rectifier assembly from the high volt-
age capacitor.
8. Now, the high voltage rectifier assembly and the high voltage
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 WITH AN EARTHING SCREW.
CONNECTION IS SECURELY FIXED TO THE CAPACI-
TOR HOLDER WITH AN EARTHING SCREW.
[4] HIGH VOLTAGE TRANSFORMER REMOVAL
1. CARRY OUT 3D CHECKS.
2. Disconnect the main wire harness from the high voltage trans-
former.
3. Disconnect the two (2) filament leads from the magnetron.
4. Disconnect the high voltage transformer secondary wire from the
high voltage capacitor.
5. Disconnect the filament lead with the high voltage wire from the
high voltage capacitor.
6. Remove the two (2) screws holding the transformer to the bottom
plate.
7. Remove the transformer from the bottom plate.
8. Now, the high voltage transformer is free.
[5] MAGNETRON REMOVAL
1. CARRY OUT 3D CHECKS.
2. Disconnect the two (2) filament leads from the magnetron.
3. Remove the one (1) screw holding the air duct to the magnetron.
4. Carefully remove the four (4) screws holding the magnetron to the
waveguide. When removing the screws hold the magnetron to pre-
vent it from falling.
vent it from falling.
5. Remove the magnetron from the waveguide with care so the mag-
netron antenna is not hit by any metal object around the antenna.
CAUTION: WHEN REPLACING THE MAGNETRON, BESURE THE
R.F. GASKET IS IN PLACE AND THE MAGNETRON
MOUNTING SCREWS ARE TIGHTENED SECURELY.
MOUNTING SCREWS ARE TIGHTENED SECURELY.
[6] ANTENNA MOTOR REPLACEMENT
1. REMOVAL
1. Disconnect the oven from the power supply.
2. Wait for 60 seconds to discharge the high voltage capacitor.
3. Remove the drip tray and the water tank.
4. Turn the oven over.
5. Remove the two (2) screws holding the bottom plate cover to the
bottom plate.
6. Remove the bottom plate cover from the bottom plate.
7. Disconnect the wire leads from the antenna motor.
8. Remove the two (2) screws holding the antenna motor to the TT
motor mount angle.
9. Now, the antenna motor is free.
2. REINSTALLATION
1. Reinstall the antenna motor by locating shaft onto the shaft assem-
bly to the TT mount angle with the two (2) screws.
2. Reconnect the wire leads to the antenna motor.
3. Insert the three (3) tabs of the bottom plate cover into the slits of the
bottom plate as shown.
4. Reinstall the bottom plate cover to the bottom plate with the two (2)
screws.
5. Reinstall the water tank and the drip tray.
[7] FAN MOTOR REPLACEMENT
1. REMOVAL
1. CARRY OUT 3D CHECKS.
2. Disconnect the wire leads from the fan motor.
3. Remove the two (2) screws holding the fan motor to the back plate.
4. Remove the fan blade from the fan motor shaft according to the fol-
lowing procedure.
i)
Hold the edge of the rotor of the fan motor by using a pair of
groove joint pliers.
groove joint pliers.
CAUTION: • Make sure that no swarf from the rotor enters the gap
between the rotor & stator of the fan motor.
• Avoid touch the coil of the fan motor with the pliers as
the coil may become cut or damaged.
• Avoid deforming the bracket whilst using the pliers.
ii) Remove the fan blade assembly from the shaft of the fan motor
by pulling and rotating the fan blade with your hand.
iii) Now, the fan blade is free.
CAUTION: Do not reuse the removed fan blade as the fixing hole may
be oversize.
5. Now, the fan motor is free.
2. INSTALLATION
1. Install the fan blade to the fan motor shaft according to the following
procedure.
