High Voltage Capacitor Removal

Disassembly Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to microwave oven and discharge the high voltage capacitor before performing any disassembly procedures.

High Voltage Capacitor Removal

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 to oven and remove control panel, see "Control Panel Removal" procedure.

2.Discharge high voltage capacitor by connecting a jumper wire to the terminal of high voltage capacitor with the diode connected to it. Connect the other end of the jumper wire to a well insulated screwdriver and touch a nearby chassis ground screw.

3.Remove screws that secure capacitor and diode.

4.Slide capacitor mounting bracket out of the slots and pull outward on capacitor, diode and bracket.

5.Reassemble in reverse order.

Diode Removal

The diode is located next to the high voltage capacitor.

1.Disconnect power to oven and remove control panel, see "Control Panel Removal" procedure.

2.Discharge high voltage capacitor, see "High Voltage Capacitor Removal" procedure.

3.Disconnect diode wire terminal from high voltage capacitor and remove screw securing diode to ground.

4.Reassemble in reverse order.

Fuse Removal

1.Disconnect power and remove grille, see "Grille Removal" procedure.

2.Remove and replace fuse and reassemble in reverse order.

!CAUTION

Before replacing a blown monitor fuse, test the primary interlock switch, secondary interlock switch, monitor switch, and power relay contacts for proper operation. If the monitor fuse is blown by a failed switch operation, all switches and printed circuit board must be replaced.

Magnetron Removal

Magnetron is mounted on the side of the cavity to provide a top feed single waveguide.

1.Disconnect power to oven and remove grille, see "Grille Removal" procedure.

2.Remove control panel, see "Control Panel Removal" procedure.

3.Remove outer case, see "Outer Case Removal" procedure.

4.Discharge high voltage capacitor, see "High Voltage Capacitor Removal" procedure.

5.Remove screws securing magnetron to wave guide.

6.Carefully remove the magnetron.

7.Reassemble in reverse order.

Transformer Removal

High voltage transformer can be serviced through the front of the unit.

Transformer Removal

1.Disconnect power to oven and remove control panel, see "Control Panel Removal" procedure.

2.Discharge high voltage capacitor, see "High Voltage Capacitor Removal" procedure.

3.Disconnect and label wire leads from transformer.

4.Remove screws securing transformer and remove out through the front.

5.Reassemble in reverse order.

Replacing Fuse

The fuse is located behind the grille in line with the power cord on the right side of the unit.

NOTE: When replacing the magnetron, make sure the gasket is in the correct position and in good condition.

!CAUTION

During replacement of magnetron, be certain the R.F. anode gasket is in place around anode stud.
