Product Code No. 43737615

See the service manual of

EM-S829(SM-860043) except

the

items described in this service manual.

Foreword

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) Do not operate or allow the oven to be operated with the door open.

(b) 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.

check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.

(d) 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.

2. POWER OUTPUT

NOTE

MEASUREMENT

The power output specification, 850W on this model is measured

with IEC measurement. The power output is measured with two (2)

liters water is equivalentto850W 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.

(c)

(D)

(E)

(F)

(G)

Set cooking time to two (2) minutes. (“2 OO-appears in

display)

Touch START key and operate oven for exactly two (2)

minutes.

Take out the two bowls atonce.

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

in degrees centigrade.

Then workout;

Power Output (watt) =70xAt

Power output shall be in the following range:

Average

Microwave

temperature rise

Power output

RE-i-=i

Power Output will be influenced by line voltage of power

supply. Consequently, correct power output must be

measured within 240V AC t 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 motoc

(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

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.

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),
