High Voltage Capacitor

High voltage capacitor should always be discharged by
shorting a terminal to a chassis ground. The capacitor
has a internal "shunt" resistor, but the mechanical
discharge should always be performed to avoid personal
injury.

High Voltage Capacitor Removal

1. Disconnect power from microwave.
2. Remove control panel, see "Control Panel"
procedure.
3. Discharge high voltage capacitor, see "High Voltage
Capacitor" procedure.
4. Remove screws securing capacitor and diode.
5. Slide capacitor mounting bracket out of slots and pull
outward on capacitor, diode and bracket.
6. Reassemble in reverse order.

High Voltage Diode

The diode is located next to the high voltage capacitor.
1. Disconnect power from microwave.
2. Remove control panel, see "Control Panel"
procedure.
3. Discharge high voltage capacitor, see "High Voltage
Capacitor" procedure.
4. Disconnect diode wire terminal from high voltage
capacitor and remove screw securing diode to
ground.
5. Reassemble in reverse order.

High Voltage Transformer

The high voltage transformer supplies the necessary
power to the microwave components.

High Voltage Transformer Removal

1. Disconnect power from microwave.
2. Remove microwave from installation position, see
"Removing Microwave from Installation Position"
procedure.
3. Remove control panel, see "Control Panel"
procedure.
4. Discharge high voltage capacitor, see "High Voltage
Capacitor" procedure.
5. Label and disconnect wire leads from transformer.
6. Remove screws securing right side of microwave
ducting to chassis.
7. Remove screws securing fan motor assembly and
remove.
8. Remove screws securing rear of microwave ducting
to chassis and remove ducting.
9. Remove screws securing high voltage transformer to
chassis.
10.Reassemble in reverse order.

To avoid the risk of electrical shock, personal injury or
death; disconnect power to microwave and discharge
capacitors before following any disassembly procedure.

Fan Motor Assembly

The fan motor assembly keeps the microwave
components cool from the cooktop below.

Fan Motor Assembly Removal

1. Disconnect power from microwave.
2. Remove microwave from installation position, see
"Removing Microwave from Installation Position"
procedure.
3. Remove control panel, see "Control Panel"
procedure.
4. Discharge high voltage capacitor, see "High Voltage
Capacitor" procedure.
5. Remove screws securing right side of microwave
ducting to chassis.
6. Remove screws securing fan motor assembly.
7. Reassemble in reverse order.

Main Fuse

The main fuse is a 20 amp fuse and is located on the
cover mounted to the noise filter, next to the high voltage
transformer fuse.

Main Fuse Removal

1. Disconnect power from microwave.
2. Remove control panel, see "Control Panel"
procedure.
3. Discharge high voltage capacitor, see "High Voltage
Capacitor" procedure.
4. Remove and replace fuse.
5. Reassemble in reverse order.
NOTE: If the 20 amp main fuse "blows" due to interlock
monitor switch failure, replace the primary
interlock switch, door sensing switch, interlock
monitor switch and power relay.
NOTE: If the 20 amp main fuse "blows" due to high
voltage transformer failure, also replace the high
voltage transformer fuse.
