5. Open the base cover from the oven cavity by pulling
down.
6. Remove the two (2) screws holding the inverter angle to
the right base plate.
7. Remove one (1) screw holding the hood duct to the oven
cavity front flange.
8. Disconnect the stop switch harness from the chassis
support and disconnect the wire leads from the fan motor.
9. Lift up the fan motor side of the hood duct.
10.Disconnect the high voltage wire from the magnetron.
11.Release the inverter angle from the right base plate.
12.Disconnect high voltage wire assembly and the inverter
wire assembly from the inverter unit.
13.Remove the three (3) screws holding the inverter unit to
the inverter angle.
14.Remove the inverter unit from the inverter angle.
Reinstallation
1. Reinstall the inverter unit to the inverter angle with the
three (3) screws.
2. Reconnect high voltage wire assembly and the inverter
wire assembly to the inverter unit. Refer to "PICTORIAL
DIAGRAM".
3. Install by sliding the inverter angle on the right base
plate.
4. Secure the inverter angle with two (2) screws to right
base plate.
5. Reinstall the base cover to the oven cavity with the three
