Disassembly Procedures
!WARNING
To avoid the risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitors before following any disassembly procedure.
Transformer
High voltage transformer can be serviced through the front of the unit.
Power Transformer Removal
1.Disconnect power to oven and remove control panel, (see "Control Panel" procedure).
NOTE: On the ACO15* and MMV5156* models, remove the metal protector located above control panel.
2.Discharge high voltage capacitor, (see "High Voltage Capacitor" 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.
Magnetron
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" procedure).
2.Remove control panel, (see "Control Panel" procedure).
NOTE: On the ACO15* and MMV5156* models, remove the metal protector located above control panel.
3.Remove outer case, (see "Outer Case" procedure).
4.Discharge high voltage capacitor, (see "High Voltage Capacitor" procedure).
5.Remove screws securing magnetron to the wave guide.
6.Carefully remove the magnetron.
7.Reassemble in reverse order.
Fuse
On the ACO15* and MMV5156* models the fuse is located behind the grille in line with the power cord on the right side of the unit.
On the ACO18*, JMV8196*, MMV4184*, and MMV5186* models the fuse is located behind the grille on the right side attached to the air duct.
Fuse Removal
1.Disconnect power and remove grille, (see "Grille 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.
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.
!WARNING
A microwave leakage test must be performed anytime a magnetron assembly is removed, replaced, disassembled or adjusted for any reason.
Magnetron Fan Assembly
Magnetron fan motor provides cool air circulation from an external air source, which provides direct cool air through air vanes surrounding the magnetron. This assembly is located above the magnetron.
Magnetron Fan Removal
1.Follow steps 1 through 4 of "Magnetron" procedure.
2.Remove fan blade from fan motor.
3.Remove screws securing fan motor to air duct.
4.Disconnect wires from fan motor, and lift fan motor assembly out.
5.Reassemble in reverse order.
