microwave energy which may radiate from the
magnetron or other microwave generating
device if it is improperly used or connection.
All input and output microwave connections,
waveguide, flange and gasket must be secure
never operate the device without a microwave
energy absorbing load attached.
Never look into an open waveguide or antenna
while the device is energized.
• Proper operation of the microwave oven
requires that
the magnetron be assembled to the waveguide
and
cavity. Never operate the magnetron unless it is
properly installed.
• Be sure that the magnetron gasket is
properly
installed around the dome of the tube
whenever
installing the magnetron.

THE HEATING PRINCIPLE OF MICROWAVE
Microwave is one kind of radio wave whose wave length is very short, frequency is very high. Therefore, it is called ultrahigh
frequency electromagnetic wave. Microwave can heat food mainly r esult in the mutual affect of the food in the microwave field and
microwave field itself.
Under the affect of microwave field, the thermal effect mechanism produced from the mutual affect of the microwave and the food
includes two aspects: One is Dielectric loss of polar molecule, the other is conductive loss of ion.
Usually, food is constitute of organism (plant and animal).The organism is formed by all kinds of polar water molecule, polar
protein molecule, and all sorts of salt ion. The center of gravity of the positive and negative charge in the molecule is not c oincide.
In normal condition, the molecule is in irregular order due to its thermal action, thus the food do not appear polarity (FIG.11a).Under the action of outer electric field, the positive end of the polar molecule tre nd to the negative electric field, the negative
end of polar molecule trend to the positive electric field, and somewhat arrange in order through the direction of the electric
field(FIG.1-1c).This phenomenon usually be called “TORQUE POLARITY”. When the outer electric field apply for the opposit e
polarity, the polar molecule then arrange an opposite direction order accordingly (FIG.1-1b).If the direction of the outer electric field
changed repeatedly, the polar molecule would repeatedly sway accordingly. During the swaying, it understands that the polar
molecule would produce heat due to somewhat similar friction among them.
When the electric field is applied for ultrahigh frequent microwave field from the outside, its direction would chang e tens billion
times per second, so do the molecule. This kind of molecule swaying producing similar frictional heat from the interference and
block of the action strength among the molecule, and changed to microscopic microwave heating. Microwave heating not only
concerned the nature of the matter itself, but also closely connected with the electric field strength and frequency. When the
frequency is low, the molecule swaying rate and the acute degree of the mutual friction among the molecule is low, and would
produce much heat. When the frequency is too high, as the swing of the polar molecule is with rotating inertia, it made the swing
do not in line with the changing rhythm of the electric field because of the friction drag, thus, actually lowed the polar molecule
swaying speed. The friction dragging degree is concerning a bout the ma gneto electric wave frequency, polar molecule shape, and
the matter’s sticky degree. To different matter’s molecule, there are different special frequency zone. Those ado absorb microwave
energy from these zone are most capable to turn microwave energy to heat energy.
Apart from the above said action, there is another action which is electric ion under t he action of microwave field, act fiercely
accompanied with the acceleration of electric field. The positive ion transfer to the negative polarity of the field while the negative
ion do opposite. Accompanying with the changing electric field, the electric ion changing according ly. During the transferring, heat
produced with the crash among the ion. This kind of action take the main effect to those microwave heating of high salt molecule.
No matter it is the polar molecule swaying or the ion transferring, they both are turning the microwave energy which the heatin g
matter got from the microwave field to hear energy. From the analysis of theory, we can draw such a conclusion that the power
which a unit of volume matter absorbed from the microwave field as the following formula:
Pa=K·E· F·Er·tgδ
Pa Stands for the power the heated matter absorbed from the microwave field.
K Stands for a constant
E Stand for microwave field strength
F Stands for the microwave frequency.
Er Stands for relative dielectric constant of the heated matter.
tgδStands for loss angle tangent of the heated matter

INSTALLATIONS
BEFORE YOU BEGIN, READ THE FOLLOWING INSTRUCTIONS COMPLETELY
INSTALLING
1. Empty the microwave oven and clean inside it with
a soft, damp cloth. Check for damage such as
misaligned door, damage around the door or dents
inside the cavity or on the exterior.
2. Put the oven on a counter, table, or shelf that is
strong enough to hold the oven and the food and
utensils you put in it. (The control panel side of the
oven is the heavy side. Use care when handling.)
3. Do not block the vent and the air intake openings.
Blocking vent or air intake openings can cause
damage to the oven and poor cooking results.
Make sure the microwave oven legs are in place to
ensure proper air flow.
4. The oven should not be installed in any area where
heat and steam are generated, because they may
damage the electronic or mechanical parts of the

MICOM CONTROLLER
• The fan motor rotates and cools the magnetron by
blowing the air (coming from the intake on the
baseplate)
• The air is also directed into the oven to exhaust the
vapor in the oven through the upper plate.
• Cooking time starts counting down.
• 3.2 volts AC is generated from the filament winding of
the high voltage transformer. This 3.2 volts is applied
to the magnetron to heat the magnetron filament
through two noise preventing choke coils.
• A high voltage of approximately 2100 volts AC is
generated in the secondary of the high voltage
transformer which is increased by the action of the high
voltage diode and charging of the high voltage
capacitor.
• The negative 4,000 Volts DC is applied to the filament
of the magnetron.

TROUBLE SHOOTING PROCEDURES
Before overhauling a microwave oven, you should judge the breakdown and the cause correctly, then you can repair it with
corresponding ways. The overhauling must be proceed in order, any hasty conclusion is not recommendable, otherwise
overworking would be done when repair. The microwave oven may occur compound breakdown due to all kinds of different
reasons, thus, when overhaul, they all should be taken into consideration. Special attention must be given to the microwave
leakage and the electric insulation when examine because they may do harmful to the repairing staff.
Ⅰ.MEANS OF THE BREAKDOWN EXAMINING
How to examine a microwave oven with breakdown? A better means which demonstrated in practical operating are through
inspecting and listening. On the basis of large amounts of perceptual knowledge, you can judge and analysis the breakdown
quickly and correctly.
1. Inspection.
Inspect whether the oven shape is disordered and where is the disordered position, if any. It is normal if the outer case
disordered a little, but abnormal if the oven, the door disordered, the door hook broken, the door crooked, or there are too
much looseness between the door and the oven after the door is closed.
2. Listening.
Listening to the voice of the oven operating and the noise of the fan after it conducted. Minor “wen wen” noise, cycling “kala”
noise and “shishi” noise should be consider as normal. But it is abnormal if the following noise occurred:
(1) Sound “wenwen” noise.
(2) Long time “shishi” noise.
(3) Strike voice like “pipa pipa”.
Ⅱ.SPOT EXAMINING STEPS OF THE MICROWAVE OVEN.
1. Examine the microwave insulating resistance.
Measure the insulating resistance with a multi meter or a mega ohmmeter. The value should not less than 2 mega ohm.
Otherwise, part examination should be taken at once. Such as checking whether the motor, the thermal cutout, the
transformer or the capacitor are electricity leaking.
2. Examination of the resistance value of the microwave oven.
Close the door, set the time (the oven is at operating condition but the power plug haven’t been pl ugged in), measure the t wo
feet(L-N)of the power plug with Rx1 grade of a multimeter, the resistance value should be about 22 ohm.
If open circuit occurred, then you must check whether the 10 A fuse is broken、the primary winding of the transformer is open
circuit、the thermal cutout is open circuit or not, you must check whether the interlock device is put through or all the plugs
are connected well. If short circuit occurred, you should check whether the primar y winding of the power transformer is shortcircuited or part short-circuited.
3. Examination of microwave leakage
Measure the microwave leakage with a microwave leakage Measure. Place a graduat e of 275ml water at the middle of the
glass tray of the oven (FIG.5-1). Close the door, power set high, time set to 3 minutes, press the starting button to operate the
oven. After rectified the microwave leakage measure, measure around the door crack, those hole position of the window and
the air vent at four sides of the oven with the probe of the measure. When meas ure, the moving speed of the probe should
not exceed 2.5cm per second, and the measuring direction should be the same with the outing direction of the microwave
leakage (FIG.5-2).
When measuring, the ultimate value of microwave leakage of all the measured position should not exceed 1.0 mili watt/cm
or should be considered as abnormal.

4. Examine when the oven at operating, but the food can’t be heated
Pull out the power plug, take off the outer case, discharge the capacitor, measure the resistance value of the primary winding and
the secondary winding of the transformer with a multi meter (FIG.5-3 and FIG.5-4). The resistance value of the primary winding
should be about 2.2 ohm, the secondary winding should be about 13 0 ohm, otherwise, it indicates the transformer has broken,
and should be replaced by a new one.
If the transformer is normal, then the high voltage capacitor should be checked. Pull out the connecting plug of the capacitor,
and measure it with Rx1 grade of a multi meter, the two rod of the multi meter connect the two polarity of the capacitor. When
they just connected, the reading of the multi meter should be zero, then enlarge to nine mega ohm slo wly. Change the rod to
different polarity, the reading repeat from zero to 9 mega ohm (FIG.5-5),it means the capacitor is normal. If the indicator of the
multi meter can’t point out from zero to 9 mega ohm, it indicates the high voltage capacitor has broken, and should be
replaced by a new one.
If it is normal between the two pole of the capacitor, then the insulation between the capacitor pole and the cabinet (FIG.5-6)
should be checked.
If the resistance value between the capacitor pole and the cabinet is “∞”,the capacitor is normal. Then c heck the earth of the
magnetron’s two filament to see whether they are short-circuited (FIG.5-7).If they are short-circuited and the filament strikes
the shell of the magnetron, it indicates the magnetron has broken, and should be replaced by a new, same model one.
If there is no problem with the magnetron, check the high voltage diode then. Measure the diode with Rx10k grade of a multi
meter, the “-” rod end of the multi meter connect the cathode of diode, the “+ “ rod end of the multi meter connect the anode of
the diode(FIG.5-8).The multi meter reading should be about 150 thousand ohm. Then change the rod to different
electrode(FIG.5-9), the reading should be “∞”.If the reading is very small, and near to short circuit, it indicates the high
voltage diode has been punctured, and should be replaced by a ne w one.
If high voltage diode is also normal, then test the pilot switch(FIG.5-10). Pull out the two plugs of the switch, Measure it with
the Rx1 grade of a multi meter, the two rod connect the plug of the switch, the resistance value should be “∞”.Then press
down the pilot switch with a screwdriver, if the reading of the multi meter pointed to zero, it indicates the pilot switch has
broken, and should replace it with a new, same model one.

Ⅲ.REPAIRING METHOD OF SEVERAL BREAKDOWN
1. Repair when there occurred large amounts microwave leakage. There are many factors, which may cau se microwave l eaking.
Following mentioned may be the main cause of microwave leakage:
(1) The door deformed, the hinge loosed or damaged that caused the door can not close tightly.
(2) The door pressing cover or the embed piece damaged or come off.
(3) Obvious damage or uneven of the oven.
(4) There are filth between the door and the oven.
(5) The door and the oven are serious loosed after the door closed.
(6) The crack of the door shielding net cover.
Before repairing, check whether the above listed point are existed, if not, you can start the microwave oven. Place a
graduate of about 275ml water at the middle of the glass tray, close the door, time set at 3 minutes, power at high,
makes the oven operating in normal. Rectify the microwave leakage measure, measure the amount of the microwave
leakage around the oven with its probe. If there are places which the leakage exceed the standard requirement, then
repair them accordingly. If the leakage amount exceed 1.0 mW/cm
take down the outer case, adjust the screws of the hinge to less the gap bet ween the door and the ove n. Then measur e
again, the leakage amount should less than 1.0 mW/cm
some allowance.
If the leakage occurred at the right door crack, adjust the screws that fix the interlock holder and the hook. If the leaka g e
is on the larger side at the right-above of the oven, then adjust the upper screw. Loosen out the screw, push the door
close to the oven to hook the door hook with the plastic parts, then tighten the screw again. If the leakage is larger at
the right-below, then adjust the lower screw. Loosen the screw, push the door close to the oven to hook the door hook
with the switch holder tightly, then tighten the screw again, and open and close the door repeatedly to check whether the
door can operate flexibly, whether the hook and the switch are in their normal position. If it is not in position, then adjust
the door hook and the switch holder the loose between the door and the oven, then measure the leakage with
microwave leakage measure again.
If there still exist microwave leakage, measure near the magnetron with the pr obe of the micro wave leakage m easure. If
the leakage is larger, the oven should be turned off and check whether the 2 or 4 screws which fix the magnetron have
been loosed, if loosed, twist them tightly with socket wrench. If the screws are fixedly, then the magnetron should be
take down to check the copper filament weaved washer of the magnetron has been placed well or whether the wave
guide housing coupling has been oxidized or have lacquer on it. If do have, scrape the oxi dized layer or the lacquer off,
when fix the magnetron, the copper filament weaved washer must be placed well, the screws must be twist tightly. Then
turn on the oven and measure again until it complies with the re quirement. If the microwave leakage is larger at those
hole position of the window board, the oven should be tur ned off to inspect whether there are crack among them. If
several holes formed a crack, it would enlarge the microwave leakage. If that is the case, it indicates the door has
broken, and should be replaced with a new door.

. Generally, it should be controlled below 0.8 mill watt/cm2 with
5-6
FIG5.10
2. Means of repair when the oven can heat, but the turntable glass can’t move
Firstly, check whether the turntable holder is placed correctly. If it is correct, then pull out the power plug and take down the
turntable combination, measure the resistance value of the turntable motor with Rx1k grade of a multi meter If it is opencircuited, it indicates the turntable motor has broken, and should be replaced by a ne w, same model one. If the resistance
value is between 15-22k,it indicates the turntable motor is normal, then check the connecting shaft weave. If the plastic that
the shaft insert in has broken, a new shaft weave should replace it.
3. Repair when the oven can heat, but the lamp is not on.
Pull out the power plug, take down the outer case and discharge the capacitor.
Pull out the two terminal plugs of the lamp, measure the two plugs of the lamp with the Rx100 grade of a multi meter. If it is
open-circuited, it indicates the lamp has broken, and should be replaced b y a same model one.
4. Means of repair when the oven stop working after several minutes operating
The phenomenon indicated the thermal cutout is playing its protective role, and you should check whether the fan is working
in normal. Turn off the oven, pull out the power plug, take down the outer case, discharge the capacitor, then turn the fan with
hand to see whether it is moving flexibly. If not, it indicates that the oil bearing of the fan motor has run off the oil, and should
take down the fan combination to repair the motor. Loosen the two screws which fix the bearing out the shaft and the bearing,
and rinse them with kerosene (ATTENTION: The bearing can only be wiped with a silk which moistened with kerosene rather
than be washed in the kerosene because there are felt on it. If the felt are soaked with kerosene, then the engi ne oil can not
be sucked up.).After the bearing being cleaned, the felt should be refueled full y with engi ne oil(for when the oven is operating,
the engine oil empty into the oil bearing slowl y).Fix the bearing cover with two screws, turn the fan around till it can move
flexibly. Than install them to the oven, and plug in the two terminal plugs.
If the fan can move flexibly, then the winding of the fan motor should be examin ed. Measure the winding with Rx100 grade of
a multi meter, if it is open-circuited, it indicates the winding of the fan motor has broken, and should be replaced by a new,
same model one.

IMPORTANT THINGS TO DO PRIOR TO CRITICAL PART
The following instructions are CRITICAL to the owner’s safety. Be sure to follow all the instructions. Contact the
manufacturer of distributor if you have any question.
1.1 If the oven is operative prior to servicing a Microwave Leakage Test (Microwave Emission Check) should be
performed prior to servicing the oven.
1.2 in the event that any microwave oven found to have microwave emission level in excess of 1 mW/cm
following procedures should be followed:
a. Inform the distributor, importer, or manufacture the finding. Record it in the logbooks well.
b. Repair the unit at no cost to the owner.
c. Investigate the oven and ascertain the cause of the excessive leakage.
d. Hold the oven in your facility and instruct the owner not to use the unit until the oven has been brought into
compliance.
1.3 In the event that the oven operates with the door open. The following procedures should be followed:
a. Tell the user not to operate the oven.
b. Hold the oven in your facility until it is investigated and repaired.
c. Contact the manufacturer immediately.
2. Interlock Assembly Replacement and Adjustment
2.1 If you suspect defective primary, secondary or monitor interlock switches, use your ohmmeter(digital or analog
type the check the electrical continuity.
2.2 Make sure the power cord is pulled out and the high-voltage capacitor is discharged before the electrical
continuity check.
2.3 Set the ohmmeter to “Low Resistance” range and connect both leads (alligator clips) to the switch terminals.
2.4 Open the door and notice the meter reading. The primar y or secondar y inte rlock s witch should sho w an “infinite”
resistance when the door is open. Replace it when it is defective. T he monitor interlock should show a “zero or
near zero” resistance when the door is open. When the door is closed, the readings will be opposite.
2.5 If the oven has been received inoperative due to the failure of the monitored safety(primary and/or secondar y)
interlock(s),you should replace all of the monitored safety interlock switched and the moni tor switch.
3. Door and Hinge Replacement and Adjustment
3.1 Pull the power cord from the outlet. Check the door for warped or damaged areas. Check the h inges for broken
or worn areas. Check other areas such as cracked from glass, broken door latched, worn/cracked viewing
screen and etc.
3.2 After determining the door assembly should be replaced, check the parts list for the correct part number. All oven
door components must be ordered directly from the manufacturer or its authorized distributor.
4. Magnetron Replacement
4.1 Check for the presence of the wire mesh gasket before installation.
4.2 Conduct a Microwave Leakage Test at the magnetron area prior to installing the top cover.

Constructional Checks
If mechanical or electrical(electronic) parts have been replaced be sure to follow the following steps.
1.1 Check for correct wiring, adequate mechanical decrements of parts, and firm connectors.
1.2 Check for adequate grounding.
1.3 Check the following items before turning the oven ON.
1) Proper door closing, seal/choke surfaces, and hinges.
2) No outer case damage.
3) Proper interlock and monitor operations.
Insulation Resistance Test
If the low voltage power supply has been repaired, use a 500 V Mega ohmmeter to measure the resistance between the
primary(Line and Neutral)of the power plug and oper ator accessible metal parts. The resistance should be no less than 2 Mega
Ohms. Repair the oven again when necessary.
