Disassembly Procedures
!WARNING
To avoid the risk of electrical shock, personal injury, or death, disconnect power to oven and discharge the capacitors before following any disassembly procedure.
Diode/Circuit Protector
1.Disconnect power to oven and remove outer case, (see "Outer Case" procedure).
2.Discharge high voltage capacitor, (see "High Voltage Capacitor" section).
3.Disconnect component from high voltage capacitor and remove screw securing diode to ground.
4.Replace component and reverse procedure to reassemble.
Transformer
1.Disconnect power to oven and remove outer case, (see "Outer Case" procedure).
2.Discharge high voltage capacitor, (see "High Voltage Capacitor" section).
3.Disconnect and label wire leads from transformer.
4.Place unit on it's back to gain access to mounting screws.
5.Remove screws securing transformer and remove.
6.Replace transformer and reverse procedure to reassemble.

Fuse / Fuse Block / Filter Assembly
1.Disconnect power to oven and remove outer case, (see "Outer Case" section).
2.Disconnect and label wires.
3.Carefully lift tabs to release assembly from plastic locating pins.
4.Replace component(s) and reverse procedure to reassemble.
!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 controller must be replaced.
Magnetron
Magnetrons are located on the side of the cavity.
1.Disconnect power to oven and remove outer case, (see "Outer Case" section).
2.Discharge high voltage capacitor, (see "High Voltage Capacitor" section).
3.Remove terminal plug from filament terminals.
4.Remove screws securing duct assembly and place to the side to gain access to magnetrons.
5.Remove screws securing magnetron being replaced to the wave guide.

6.Replace magnetron and reverse procedure to reassemble.
NOTE: When replacing magnetron, make sure gasket is
in correct position and in good condition.
!CAUTION
During replacement of magnetron, be certain the R.F. anode gasket is in place around the anode stud.
!WARNING
A microwave leakage test must be performed anytime a magnetron assembly is removed, replaced, disassembled, or adjusted for any reason.
