Foreword
except the items described in this service manual.
Read this manual carefully, especially precaution on microwave energy, and follow the procedure strictly.
Careless servicing and testing may expose yourself to the microwave energy leakage.

PRECAUTIONS
PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO
EXCESSIVE MICROWAVE ENERGY
(a)
(b)
(c)
(d)
Do not operate or allow the oven to be operated with the door open.
Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave
source, and make repairs as necessary:
(1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage),
(4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.
Before turning on microwave power for any service test or inspection within the microwave generating compaflments,
check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.
Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmis-
sion systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is
released to the owner.

MEASUREMENT
(G)
Thepower output specification, 900W on this model is measured
with IEC measurement. Thepower output ismeasured with two(2)
liters water is equivalent to900W in measurement with lEC, when
measured with the following power output.
(A) 1. Fill twotest bowls with eachl Iiter water respectively.
2. Use accurate thermometer and measure each water
temperature respectively.
(B) Place thetwobowls on glass turntable.

Set cooking time to two (2) minutes. (“2 00” appears in
display)
Touch START key and operate oven for exactly two (2)
minutes.
Take out the two bowls at once.
Stir both water with thermometer and measure the water
temperature rise respectively.
Get temperature rise by calculating the difference (water
temperature after cooking minus initial temperature) in
each bowl.
Then calculate average value(t) of both temperature rises
m degrees centigrade.
Then workout;
Power Output (watt) = 70 x At
Power output shall be in the following range:

Maximum

Power Output will be influenced by line voltage of power
supply. Consequently, correct power output must be
measured within 240VAC +2 volts while unit is operating.

5. DISASSEMBLY INSTRUCTIONS
A. REMOVING BLOWER MOTOR
(Figures 3 (Top View) and 4)
(1)Remove screw securing the stay.
(2) Disconnect all lead wires from the blower motor
and H.V. capacitor.
(3) Remove 2 screws securing the blower base and
disengage 3 hooks from the rear plate of cavity
(Figure 4)
(4) Remove 1 screw securing the blower motor with
the blower base.
B. REMOVING MAGNETRON
(Figure 3 (Top View))
After removing the blower motor:
(1) Remove duct (msg. intake) and duct (msg.
-
exhaust).
(2) Remove 1 screw securing the thermal protector.
(3) Disconnect 2 lead wires from the magnetron.
(4) Remove 4 screws securing the magnetron to the
waveguide.
(5) Take out magnetron VERY CAREFULLY.
NOTES
1.
When removing the magnetron from the cavity or
L
wave guide, use a proper care so that the dome of
the magnetron does not hit any adjacent parts of
microwave oven.
2. Make sure that the contact face of the magnetron
gasket is free from any damage or deformation.
3. Adjust the position of the magnetron properly, so
that it correctly sits in place and the magnetron
gasket is in contact with the mounting rim evenly.
L.
4. While holding the magnetron under this condition,
tighten mounting screws or nuts with your fingers
temporarily.
5. Further tighten the screws or nuts with a box
wrench, giving one or two turns to each of the
screws (or nuts) alternatively so that the magnetron
is mounted on to the bracket uniformly.
6. After replacing the magnetron, be sure to check the
microwave energy leakage with a leakage detector
and confirm the leakage is below 5mW/cmZ.
NOTES
When inserting duct (msg. exhaust), overlap the lower
tab of the duct onto the magnetron, at the same time
-. ensure the hook on the duct is properly engage to the
magnetron (See figure 5).
