INTERLOCK MECHANISM AND ADJUSTMENT
The door lock m echanism is a device which has been specially designed to com pletely elim inate m icrowave radiation when
the door is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave.
(1) Prim ary interlock switch
W hen the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate.
W hen the door is closed, the hook pushes the button of the m icroswitch. Then the button of the primary interlock switch
bring it under ON condition.
(2) Secondary interlock switch and interlock m onitor switch
W hen the door is closed, the hook pushes the lock lever downward. The lock lever presses the button of the interlock
m onitor switch to bring it under NO condition and presses the button of the secondary interlock switch to bring it under
ON condition.
ADJUSTMENT
Interlock m onitor switch
W hen the door is closed, the interlock m onitor sw itch should be changed(NO condition) before other switches are closed.
W hen the door is opened, the interlock m onitor sw itch should be changed(NC condition) after other switches are opened.
(3) Adjustm ent steps
a) Loosen the one m ounting screw.
b) Adjust interlock switch assem bly position.
c) M ake sure that lock lever m oves sm oothly after adjustm ent is com pleted.
d) Tighten com pletely one m ounting screw.
NOTE
M icrow ave em ission test should be perform ed after adjusting interlock m echanism . If the m icrow ave em ission exceed
4m W /cm 2 , readjust interlock m echanism .
TROUBLE SHOOTING GUIDE

MEASUREMENT AND TEST
1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT
M icrowave output power can be checked by indirectly m easuring the tem perature rise of a certain am ount of water exposed
to the m icrowave as directed below.
PROCEDURE
1. M icrowave power output m easurem ent is m ade with the m icrowave oven supplied at rated voltage and operated at its
m axim um m icrowave power setting with a load of 1000 ± 5cc of potable water.
2. The water is contained in a cylindrical borosilicate glass vessel having a m axim um m aterial thickness of 3 m m and an
outside diam eter of approxim ately 190 m m .
3. The oven and the em pty vessel are at am bient tem perature prior to the start of the test. The initial tem perature of the
water is 10 ± 2 ° C (50 ± 3.6 ° F). It is m easured im m ediately before the water is added to the vessel. After addition of
the water to the vessel, the load is im m ediately placed on the center of the shelf, which is in the lowest norm al position.
4. M icrowave power is switched on.
5. Heating tim e should be exactly A seconds.
(Refer to table as following)
Heating tim e is m easured while the
m icrowave generator is operating at
full power. The filam ent heat-up tim e
for m agnetron is not included.
6. The initial and final tem perature of water is selected
so that the m axim um difference between the am bient
and final water tem perature is 5K.
7. The m icrowave power output P in watts is calculated
from the following form ula:
P = 4187 X
T
T is difference between initial and ending tem perature.
t is the heating tim e.
The power m easured should be B (Refer to SPECIFICATIONS) W ± 10.0 % .
CAUTION
1. W ater load should be m easured exactly to 1 liters.
2. Input pow er voltage should be exactly specified voltage (R efer to S PE C IFIC ATIO N S ).
3. A m bient tem perature should be 20 ± 2° C (68 ± 3.6 ° F)

MEASUREMENT AND TEST
2. MICROWAVE RADIATION TEST
CAUTION
1. M ake sure to check the m icrowave leakage before and after repair of adjustm ent.
2. Always start m easuring of an unknown field to assure safety for operating personnel from m icrowave energy.
3. Do not place your hands into any suspected m icrowave radiation field unless the safe density level is known.
4. Care should be taken not to place the eyes in direct line with the source of m icrowave energy.
5. Slowly approach the unit under test until the radiom eter reads an appreciable m icrowave leakage from the unit
under the test.
PROCEDURE
1. Prepare M icrowave Energy Survey M eter,
600cc glass beaker, and glass therm om eter
100° C (212° F ).
2. Pour 275cc ± 15cc of tap water initially at 20 ± 5 ° C
(68 ± 9° F) in the 600 cc glass beaker with an inside
diam eter of approx. 95 m m (3.5 in.).
3. Place it at the center of the tray and set it in a cavity.
4. Close the door and operate the oven.
5. M easure the leakage by using M icrowave Energy
Survey M eter with dual ranges, set to 2450M Hz.
1) M easured radiation leakage m ust not exceed the
value prescribed below. Leakage for a fully assem bled
oven with door norm ally closed m ust be less than 4m W /cm 2 .
2) W hen m easuring the leakage, always use the 5 cm (2 in.) space cone with probe. Hold the probe perpendicular to the
cabinet and door. Place the space cone of the probe on the door, cabinet, door seem , door viewing screen, the exhaust
air vents and the suction air vents.
3) M easuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the leakage of the cabinet door seem is
unknown, m ove the probe m ore slowly.
4) W hen m easuring near a corner of the door, keep the probe perpendicular to the areas m aking sure the probe end at
the base of the cone does not get closer than 2 in. from any m etal. If it does not, erroneous reading m ay result.
MEASUREMENT AND TEST
3. COMPONENT TEST PROCEDURE
High voltage is present at the high voltage term inal of the high voltage transform er during any cooking cycle.
It is neither necessary nor advisable to attem pt m easurem ent of the high voltage.
Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor.
1. High voltage transformer
1) Rem ove connections from the transform er term inals and check continuity.
2) Norm al readings should be as follows :
Secondary winding ... Approx. 110
± 10%
Filam ent winding ... Approx. 0
Prim ary winding ... Approx. 1
2. High voltage capacitor
1) Check continuity of capacitor with m eter on the highest OHM scale.
2) A norm al capacitor will show continuity for a short tim e, and then indicate 10M
3) A shorted capacitor will show continuous continuity.
once the capacitor charged.
4) An open capacitor will show constant 10M .
5) Resistance between each term inal and chassis should be infinite.
3. High voltage diode
1) Isolate the diode from the circuit by disconnecting the leads.
2) W ith the ohm m eter set on the highest resistance scale m easure the resistance across the diode term inals. Reverse
the m eter leads and again observe the resistance reading. M eter with 6V, 9V or higher voltage batteries should be
used to check the front-back resistance of the diode, otherwise an infinite resistance m ay be read in both directions. A
norm al diode's resistance will be infinite in one direction and several hundred k
in the other direction.
4. Magnetron
For com plete m agnetron diagnosis, refer to “M easurem ent of the M icrowave Power Output. " Continuity checks can only
indicate and open filam ent or a shorted m agnetron. To diagnose for an open filam ent or a shorted m agnetron,
1) Isolate m agnetron from the circuit by disconnecting the leads.
2) A continuity check across m agnetron filam ent term inals should indicate 0.1
or less.
3) A continuity check between each filam ent term inal and m agnetron case should read open.
5. Fuse
If the fuse in the prim ary and m onitor switch circuit is blown when the door is opened, check the prim ary and m onitor
switch before replacing the blown fuse. In case the fuse is blown by an im proper switch operation, replace the defective
switch and fuse at the sam e tim e. Replace just the fuse if the switches operate norm ally.
