13.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.

HOOD FAN THERMAL CUT-OUT REMOVAL

1.Disconnect the power supply cord and 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.To discharge the high voltage capacitor, wait for 60 seconds.

4.Remove the three (3) screws holding the hood intake duct R to the oven cavity top plate, the oven cavity front flange

and the fan duct. And remove the hood intake duct R.

5.Disconnect the wire leads from the hood fan thermal cut-out.

6.Remove one (1) screw holding the thermal cut-out to the flange of base plate R (turntable motor side).

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

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

THERMAL CUT-OUT (CAVITY) REMOVAL

1.Disconnect the power supply cord and 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.To discharge the high voltage capacitor, wait for 60 seconds.

4.Disconnect the wire leads from the thermal cut-out (cavity).

5.Remove the thermal cut-out (cavity) from the holder at the oven cavity bottom plate.

6.Now, the thermal cut-out (cavity) is free.
