to free it from retaining clips on the cavity face plate.
6. Lift entire outer case from the unit.
CAUTION: 1. DISCONNECT OVEN FROM POWER SUP-
PLY BEFORE REMOVING OUTER CASE.
2. DISCHARGE THE HIGH VOLTAGE CA-
MAGNETRON REMOVAL
6. Remove the magnetron from waveguide.
7. 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.
1. Disconnect the power supply cord and remove outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the wire leads from magnetron.
5. Remove the three (3) screws holding the magnetron to
the waveguide.
To remove the components, proceed as follows.
1. Disconnect the power supply cord and remove outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Remove one (1) screw holding capacitor holder to rear
cabinet.
5. Disconnect the H.V. wire of the H.V. rectifier assembly
from the magnetron.
6. Disconnect the filament lead of the power transformer
from the H.V. capacitor.
7. Remove one (1) screw holding ground side terminal of
high voltage rectifier assembly, and remove capacitor
holder.
8. Disconnect all the leads and terminals of high voltage
rectifier assembly from high voltage capacitor.
9. Now the H.V. rectifier assembly and H.V. capacitor
should be free.
CAUTION: WHEN REPLACING HIGH VOLTAGE RECTI-
FIER ASSEMBLY, ENSURE THAT THE CATH-
ODE (GROUND) CONNECTION IS SE-
CURELY FIXED TO THE CAPACITOR
HOLDER WITH A GROUNDING SCREW.
CAUTION: DO NOT REPLACE ONLY HIGH VOLTAGE
RECTIFIER. WHEN REPLACING IT, RE-
PLACE HIGH VOLTAGE RECTIFIER ASSEM-
BLY.
HIGH VOLTAGE COMPONENTS REMOVAL
(HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY)
POWER TRANSFORMER REMOVAL
1. Disconnect the power supply cord and remove outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the wire leads (main wire harness) from
power transformer.
5. Disconnect the lead from magnetron filament.
6. Disconnect the leads of the power transformer from high
voltage capacitor.
7. Remove four (4) screws (two (2) screws from the upper
side and two (2) screws from bottom side) holding
transformer to bottom plate.
8. Remove the transformer.
9. Now the power transformer is free.
Re-install
1. Rest transformer on the bottom plate with its primary
terminals toward the oven face plate.
2. Secure transformer with four (4) screws to the bottom
plate (two (2) screws from the upper side and two (2)
screws from bottom side).
3. Re-connect wire leads (primary and high voltage) and
filament leads to the power transformer, magnetron and
high voltage capacitor, referring to "Pictorial Diagram".
4. Re-install outer case and check that the oven is operating
properly.
PACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
NOTE: When replacing the outer case, the 2 special
Torx screws must be reinstalled in the same
locations.
