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 of main wire harness and
H.V. wire (for using RTRN-A646WRZZ) from power
transformer.
5. Disconnect the lead from magnetron filament.
6. Disconnect the lead(s) of the power transformer from
high voltage capacitor.
7. Remove the two (2) screws holding the transformer to
bottom plate from below.
8. Remove the two (2) screws holding the transformer to
bottom plate from above.
9. Remove the transformer.
10.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 two (2) screws to the bottom
plate from above.
3. Secure transformer with two (2) screws to the bottom
plate from below.
4. Re-connect wire leads (primary and high voltage) and
filament leads to the power transformer, magnetron and
high voltage capacitor, referring to "Pictorial Diagram".
5. Re-install outer case and check that the oven is operating
properly.
Microwave ovens contain circuitry capable of producing very high voltage and current, contact with following parts may
result in severe, possibly fatal, electric shock.
(Example)
High Voltage Capacitor, Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness etc..
WARNING:
Avoid possible exposure to microwave energy. Please follow the instructions below before
operating the oven.
WARNING AGAINST HIGH VOLTAGE:
COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
To prevent an electric shock, take the following pre-
cautions.
1. Before wiring,
1) Disconnect the power supply cord.
2) Open the door and block it open.
3) Discharge the high voltage capacitor and wait for 60
seconds.
2. Don’t let the wire leads touch to the followiong parts;
1) High voltage parts:
Magnetron, High voltage transformer, High voltage
capacitor and High voltage rectifier assembly.
2) Hot parts:
Oven lamp, Magnetron, High voltage transformer
WARNING FOR WIRING
1. Disconnect the power supply cord.
2. Visually check the door and cavity face plate for damage
(dents, cracks, signs of arcing etc.).
Carry out any remedial work that is necessary before
operating the oven.
Do not operate the oven if any of the following conditions
exist;
1. Door does not close firmly.
2. Door hinge, support or latch hook is damaged.
3. The door gasket or seal is damaged.
4. The door is bent or warped.
5. There are defective parts in the door interlock system.
6. There are defective parts in the microwave generating
and transmission assembly.
7. There is visible damage to the oven.
Do not operate the oven:
1. Without the RF gasket (Magnetron).
2. If the wave guide or oven cavity are not intact.
3. If the door is not closed.
4. If the outer case (cabinet) is not fitted.
and Oven cavity.
3) Sharp edge:
Bottom plate, Oven cavity, Waveguide flange,
Chassis support and other metallic plate.
4) Movable parts (to prevent a fault)
Fan blade, Fan motor, Switch.
3. Do not catch the wire leads in the outer case cabinet.
4. Insert the positive lock connector until its pin is locked
and make sure that the wire leads do not come off even
if the wire leads are pulled.
5. To prevent an error function, connect the wire leads
correctly, referring to the Pictorial Diagram.
