Magnetron Removal - Electrolux EI30BM55HB Technical & Service Manual

Magnetron Removal

1. Disconnect the power supply cord and remove
the oven from wall and remove outer case. (Refer
to procedure of "Removal of Oven from Wall" and
"Outer Case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for
60 seconds.
4. Remove two (2) screws holding the chassis sup-
port right to the rear and face of the oven cavity
flanges.
5. Remove the one (1) screw holding the noise filter
assembly to the fan duct.
6. Disconnect the wire leads from the fan motor.
7. Disconnect the high voltage wire leads of the high
voltage rectifier assembly from the
magnetron.
8. Disconnect the filament lead of the transformer
from the magnetron.
9. Remove the one(1) screw holding the hood duct
to the fan duct and remove the one (1) screw
holding the oven cavity top plate to the fan duct.
10. Remove the one(1) screw holding the right base
plate to the fan duct and remove the fan duct
assembly.
11. Remove the power transformer from the right
base plate, referring to "POWER TRANS-
FORMER REMOVAL".
12. Carefully remove four (4) mounting screws
holding the magnetron to waveguide. When
removing the screws hold the magnetron to
prevent it from falling.
13. Remove the magnetron from the unit with care so
the magnetron tube should not be hit by any
metal object around the tube.
CAUTION
WHEN REPLACING THE MAGNETRON, BE SURE
THE R.F. GASKET IS IN PLACE AND
MOUNTING SCREWS ARE TIGHTENED
SECURELY.
Component Teardown
High Voltage Rectifier and High
Voltage Capacitor Removal
1. Disconnect the power supply cord and remove
the oven from wall and remove outer case. (Refer
to procedure of "Removal of Oven from Wall" and
"Outer Case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for
60 seconds.
4. Disconnect the high voltage wire leads with high
voltage rectifier from the magnetron.
5. Disconnect filament lead of the transformer from
high voltage capacitor.
6. Disconnect high voltage wire from capacitor.
7. Remove one (1) screw holding capacitor holder
and high voltage rectifier to the fan duct.
8. Disconnect the high voltage rectifier assembly
from the high voltage capacitor and remove one
(1) screw holding the voltage rectifier assembly to
the capacitor holder.
9. Now, the high voltage rectifier assembly is free.
10. Remove capacitor from the holder.
11. Now, the high voltage capacitor is free.
CAUTION
WHEN REPLACING THE HIGH VOLTAGE
RECTIFIER ASSEMBLY, THE GROUND SIDE
TERMINAL MUST BE SECURED FIRMLY WITH A
GROUNDING SCREW.
