Outer Case Removal
To remove the outer case, proceed as follows:
1. Disconnect the power supply cord.
2. Remove screws from rear and along the side edge of
case.
3. Slide the entire case back out about 1 inch (3 cm) to
free it from retaining clips on the cavity face plate.
4. Lift entire case from the unit.
1. Disconnect oven from power supply before
removing outer case.
2. Discharge the high voltage capacitor before
touching any oven components or wiring.
Power Transformer Removal
Removal
1. Disconnect the oven power supply cord and remove
outer case.
2. Discharge high voltage capacitor.
3. Disconnect filament leads of transformer from the
magnetron and capacitor.
4. Disconnect high voltage lead of capacitor from the
transformer.
5. Disconnect wire leads from the transformer.
6. Remove two (2) screws holding the transformer to the
base
cabinet.
Re-Install
1. Rest the transformer on the base cabinet with its
primary terminals toward rear cabinet.
2. Insert the two edges of the transformer into two metal
tabs of the base cabinet.
3. Make sure the transformer is mounted correctly to the
corners underneath those tabs.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.

4. After re-installing the transformer, secure the
transformer with two screws to the base cabinet, one
is with outer tooth washer and the other is without
outer-tooth washer.
5. Re-connect the wire leads (primary and high voltage)
and high voltage lead to the transformer and filament
leads of transformer to the magnetron and capacitor,
referring to the “Pictorial Diagram”.
6. Re-install the outer case and check that the oven is
operating
properly.
Magnetron Removal
1. Disconnect oven from power supply and remove
outer case.
2. Discharge the high voltage capacitor. Disconnect
filament lead of transformer from magnetron.
Disconnect high voltage wire lead from magnetron.
3. Carefully remove four (4) mounting screws hold the
magnetron to waveguide, when removing the screws
holding the magnetron to prevent it from falling.
4. Remove the magnetron from the unit with care so the
magnetron tube should not hit by any metal object
around the tube.
Hot (orange) wire must be connected to the power
transformer terminal nearest to the transformer
mounting screw.
When replacing the magnetron, be sure the R.F.
Gasket is in place and mounting screws are
tightened securely.
