voltage capacitor.

6.  Disconnect high voltage wire lead of capacitor from the 

transformer.

7.  Remove  one (1) screw holding capacitor holder to the 

back plate. 

8.  Remove    one  (1)  screw  holding  high  voltage  rectifier 

from the capacitor holder.

9.  Disconnect the high voltage rectifier assembly from the  

high voltage capacitor.

10. Now, the high voltage rectifier assembly is free.
11.  

Remove capacitor from the holder.

12. Now, the high voltage capacitor is free.
CAUTION:  WHEN  REPLACING  THE  HIGH  VOLTAGE 

RECTIFIER ASSEMBLY, THE GROUND SIDE 
TERMINAL MUST BE SECURED FIRMLY WITH 
A GROUNDING SCREW.

1.  Disconnect the power cord, remove the oven from wall 

and remove outer case. (Refer to procedure of "Removal 
of Oven from Wall" and "Outer case Removal")

2.  Open the door and block it open.
3.  Discharge high voltage capacitor.

4.  Disconnect  the  wire  leads  from  the  hood  fan  thermal 

cut-out.

5.  Remove the hood fan thermal cut-out from the base plate 

right.

6.  Now, the hood fan thermal cut-out is free.

 HOOD FAN THERMAL CUT-OUT REMOVAL

5.  Disconnect  the  wire  leads  from  the  temperature  fuse 

(Magnetron).

6.  Remove the one (1) screw holding the temperature fuse 

(Magnetron) to the oven cavity.

7.  Now, the temperature fuse (Magnetron) is free.

1.  Disconnect  the  power  supply  cord,  remove  the  oven 

from wall and remove outer case. (Refer to procedure of 
"Removal of Oven from Wall" and "Outer case Removal")

2.  Open the door and block it open.
