HIGH VOLTAGE COMPONENTS REMOVAL

(HIGH VOLTAGE CAPACITOR, HIGH VOLTAGE RECTIFIER ASSEMBLY AND H.V. FUSE)

To remove the components, proceed as follows.

1.CARRY OUT 3D CHECKS.

2.Disconnect the H.V. fuse from the power transformer.

3.Disconnect the H.V. wire of the H.V. rectifier assembly from the magnetron.

4.Disconnect the wire leads from the noise filter.

5.Remove one (1) screw holding capacitor holder to oven cavity back plate.

6.Disconnect the filament lead of the power transformer from the H.V. capacitor.

7.Remove one (1) screw holding earth side terminal of high voltage rectifier assembly, and remove capacitor holder.

8.Disconnect all the leads and terminals of high voltage rectifier assembly from high voltage capacitor.

9.Disconnect the H.V. fuse from high voltage capacitor. 10.Remove the HVC cover from the high voltage capacitor. 11.Now H.V. rectifier assembly, H.V. fuse and H.V. ca-

pacitor should be free.

CAUTION: WHEN REPLACING HIGH VOLTAGE REC- TIFIER ASSEMBLY, ENSURE THAT THE CATHODE (EARTH) CONNECTION IS SE- CURELY FIXED TO THE CAPACITOR HOLDER WITH AN EARTHING SCREW.

CAUTION: DO NOT REPLACE ONLY HIGH VOLTAGE RECTIFIER. WHEN REPLACING IT, RE- PLACE HIGH VOLTAGE RECTIFIER AS- SEMBLY.

MAGNETRON REPLACEMENT

Removal

1.CARRY OUT 3D CHECKS.

2.Disconnect the wire leads from the magnetron.

3.Carefully remove the two (2) screws holding the magnetron to the waveguide flange.

4.Lift up magnetron with care so that the magnetron antenna is not hit by any metal object around antenna.

5.Now, the magnetron is free.

Re-install

1.Re-install the magnetron to the waveguide flange with two (2) screws diagonally as shown in Figure C-1.

2.Re-connect the wire leads to the magnetron. Refer to

"PICTORIAL DIAGRAM".

3.Re-install the outer case and check that the oven is operating properly.

CAUTION: WHEN REPLACING THE MAGNETRON, BE SURE THE R.F. GASKET IS IN PLACE AND THE MAGNETRON MOUNTING SCREWS ARE TIGHTENED SECURELY.

OVEN LAMP SOCKET REMOVAL

1.CARRY OUT 3D CHECKS.

2.Pull the wire leads from the oven lamp socket by pushing the terminal hole of the oven lamp socket with the flat type small screw driver.

3.Tear the cushion from the light mount plate.

4.Bend the tab of the light mount plate holding the oven.

5.Lift up the oven lamp socket.

6.Now, the oven lamp socket is free.
