The following procedure enables the servicer to obtain the
total service counts (cook cycles) for memory cooking,
manual, repeat, double quantity cooking and defrost. The
maximum capacity of the counter is 999,999 counts, above
which the counter will reset to "0". The counter will retain the
total counts (will not clear) in the event of a power disruption.

1) Practice for checking total service counts
     (eg; 234,567 Counts).

#1: Denotes total service counts within the reach of user, of

which checking and clearing practices are described in
this instruction manual.

#2: Denotes the procedure for the servicer to disable check-

ing/clearing. This procedure is instructed to service
personnel only and is excluded from the operation manual.

rear cabinet and lower left portion of the oven cabinet
back side using by special screw drive (Type; LHSTIX
DLR4-100T).

4. Remove the screws from rear and along the side edge

of case.

5. Slide the entire case back about 3cm to free it from

retaining clips on the cavity face plate.

6. Lift the entire case from the oven.
7. Remove the screws holding the rear cabinet to the

oven.

8. Remove the rear cabinet.
9. Discharge the HV capacitor before carrying out any

further work.

10.Do not operate the oven with the outer case removed.

N.B.; Step 1,2 and 9 form the basis of the 3D checks.

CAUTION:DISCHARGE HIGH VOLTAGE CAPACI-

TOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.

1. CARRY OUT 3D CHECKS.
2. Make sure that a definite” click” can be heard when the

microwave oven door is unlatched. (Hold the door in
a closed position, then pull the door release lever with
one hand, this causes the latch leads to rise, it is then
possible to hear a “click’ as the door switches oper-
ate.)

3. Visually check the door and cavity face plate for

damage (dents, cracks, signs of arcing etc.).

Carry out any remedial work that is necessary before
operating the oven.
Do not operate the oven if any of the following conditions
exist;

1. Door does not close firmly.
2. Door hinge, support or latch hook is damaged.
3. The door gasket or seal or damaged.
4. The door is bent or warped.
5. There are defective parts in the door interlock system.
6. There are defective  parts in the microwave generating

and transmission assembly.

7. There is visible damage to the oven.

Do not operate the oven:
1. Without the RF gasket (Magnetron).
2. If the wave guide or oven cavity are not intact.
3. If the door is not closed.
4. If the outer case (cabinet) is not fitted.

Please refer to ‘OVEN PARTS, CABINET PARTS, DOOR PARTS’, when carrying out any of the following removal
procedures:

TIFIER. WHEN REPLACE IT, REPLACE HIGH
VOLTAGE RECTIFIER ASSEMBLY.

2. WHEN REPLACING HIGH VOLTAGE RECTIFIER

ASSEMBLY, ENSURE THAT THE CATHODE
(EARTH) CONNECTION IS SECURELY FIXED
TO THE CHASSIS WITH A EARTHING SCREW.

6. Now, the two (2) high voltage capacitors are free.

To remove the components, proceed as follows.
1. CARRY OUT 3D CHECKS.
2. Remove two (2) screws holding earth side terminals of

high voltage rectifier assemblies.

3. Disconnect all the leads and terminals of high voltage

rectifier assembly from high voltage capacitor.

4. Remove two (2) screws holding capacitor holder to the

right side of oven cavity and remove the capacitor
holder.
