COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
(HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY)
To remove the components, proceed as
follows.
1. CARRY OUT 3D CHECKS
2. Disconnect all the leads and terminal of high
voltage rectifier from high voltage capacitor.
3. Remove one (1) screw holding earth side
terminal of high voltage rectifier, and remove
capacitor holder from the base plate.
4. Remove the capacitor from the capacitor
holder.
5. Now the high voltage rectifier and capacitor
should be free.
1. CARRY OUT 3D CHECKS
2. Disconnect the filament leads of the power
transformer from high voltage capacitor and the
magnetron.
3. Disconnect the H.V. secondary wire from the
power transformer.
1. CARRY OUT 3D CHECKS.
2. Disconnect the H.V. wire B and filament lead of
the transformer from the magnetron.
3. Move the air intake duct to left.
4. Carefully remove two (2) screws holding
magnetron to the waveguide.
5. Remove the magnetron from the waveguide with
care so the magnetron antenna is not hit by any
metal object around the antenna.
1. CARRY OUT 3D CHECKS.
2. Disconnect the main wire harness from the
control panel.
3. Remove the one (1) screw holding the control
panel to the oven cavity.
1. Disconnect the oven from the power supply.
2. Remove the turntable motor cover by snipping
off the material in four corners.
3. Where the corners have been snipped off bent
corner areas flat. No sharp edge must be
evident after removal of turntable motor cover.

HIGH VOLTAGE COMPONENTS REMOVAL
HIGH VOLTAGE TRANSFORMER REMOVAL
MAGNETRON REMOVAL
CONTROL PANEL ASSEMBLY REMOVAL
TURNTABLE MOTOR REMOVAL
CAUTION: WHEN REPLACING HIGH
VOLTAGE RECTIFIER ASSEMBLY,
ENSURE THAT THE CATHODE
(EARTH) CONNECTION IS
SECURELY FIXED TO THE
CAPACITOR HOLDER AND
BASEPLATE WITH AN EARTHING
SCREW.
4. Remove the four (4) screws holding the
transformer to base plate (from the under side).
5. Remove the transformer from the baseplate by
sliding it away from the oven cavity and lifting it.
6. Now, the power transformer is free.
CAUTION: WHEN REPLACING THE MAGNETRON,
BE SURE THE R.F. GASKET IS IN
PLACE AND THE MAGNETRON
MOUNTING SCREWS ARE TIGHTENED
SECURELY. REINSTALL THE
MAGNETRON TO WAVE GUIDE
FLANGE WITH THE TWO (2) SCREWS
DIAGONALLY.
ENSURE THE MAGNETRON WIRING IS
REFITTED IN ACCORDANCE WITH
THE PICTORIAL DIAGRAM ON PAGE
33 (FA AND F).
4. Lift the control panel assembly and pull it
forward. Now, the control panel assembly is
free.
4. Disconnect the wire leads from the turntable
motor and remove the one (1) screw holding the
turntable motor.
5. Turntable motor is now free.
6. After replacement use one (1) screw to fit the
turntable motor cover.(code 5028 05 76-00/5).
