COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
To remove the outer case, proceed as follows.
1. Disconnect oven from power supply.
2. Open door and wedge it open.
3. Remove the one (1) screw holding the air duct to the
oven cavity rear plate.
4. Remove athe air duct.
5. Remove the nine (9) screws from rear and along the
side edge of case.
6. Slide the entire case back about 3 cm to free it from
retaining clips on the cavity face plate.
(HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY)
To remove the components, proceed as follows.
1. CARRY OUT 3D CHECKS
2. Disconnect the filament leads of the high
voltage transformer and the high voltage wire of
the high voltage capacitor.
3. Disconnect the high voltage wire B from the high
voltage capacitor.
Remove one (1) screw holding earth side
4.
terminal of the high voltage rectifier assembly to
the base plate through the capacitor holder.
5. Release the capacitor holder from the base
plate.
6. Remove the high voltage capacitor from the
capacitor holder.
1. CARRY OUT 3D CHECKS
2. Disconnect the main wire harness from the high
voltage transformer.
3. Disconnect the filament leads and high voltage
wire of high voltage transformer from high voltage
capacitor and the magnetron.
1. CARRY OUT 3D CHECKS.
2. Disconnect the H.V. wire B (part of H.V. transformer)
and filament lead of the transformer from the
magnetron.
3. Carefully remove three(3) screws holding the
magnetron to the waveguide, when removing the
screws hold the magnetron to prevent it from falling.
4. Remove the one (1) screw holding the magnetron to
the chassis support.

7. Lift the entire case from the oven.
8. Discharge the H.V capacitor before carrying any
further work.
9. Do not operate the oven with the outer case
removed.
N.B. : Step 1, 2 and 8 from the basis of the 3D checks.
CAUTION: DISCHARGE HIGH VOLTAGE
CAPACITOR BEFORE TOUCHING ANY
OVEN COMPONENTS OR WIRING.
7. Disconnect the high voltage rectifier assembly from
the high voltage capacitor.
8. Now, the high voltage rectifier assembly and the
high voltage capacitor should be free.
CAUTION: WHEN REPLACING HIGH
RECTIFIER ASSEMBLY, ENSURE
THAT THE CATHODE (EARTH)
CONNECTION IS SECURELY FIXED
TO THE CAPACITOR HOLDER AND
BASEPLATE WITH AN EARTHING
SCREW.
4. Remove the two (2) screws and one (1) washer
holding the transformer to the base plate.
5. Remove the transformer.
6. Now the high voltage transformer is free.
5. Remove the magnetron from the waveguide with
care so the magnetron antenna is not hit by any
metal object around the antenna.
6. Now, the magnetron is free.
CAUTION: WHEN REPLACING THE MAGNETRON,
BE SURE THE R.F. GASKET IS IN
PLACE AND THE MAGNETRON
MOUNTING SCREWS ARE TIGHTENED
SECURELY.
