INTERLOCK MECHANISM AND ADJUSTMENT
The door lock mechanism is a device which has been specially designed to completely eliminate microwave radiation when the door
is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave.
1) KOR-1A1G/H 2) KOR-1A4G/H and KOR-1A7Q
(1) Primary interlock switch
When the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate.
When the door is closed, the hook pushes the button of the microswitch. Then the button of the primary interlock switch
bring it under ON condition.
(2) Secondary interlock switch and interlock monitor switch
When the door is closed, the hook pushes the lock lever downward. The lock lever presses the button of the interlock
monitor switch to bring it under NO condition and presses the button of the secondary interlock switch to bring it under ON
condition.
ADJUSTMENT
Interlock monitor switch
When the door is closed, the interlock monitor switch should be changed (NO condition) before other switches are closed.
When the door is opened, the interlock monitor switch should be changed (NC condition) after other switches are opened.
(3) Adjustment steps
a) Loosen the one mounting screw.
b) Adjust interlock switch assembly position.
c) Make sure that lock lever moves smothly after adjustment is completed.
d) Tighten completely one mounting screw.
NOTE
Microwave emission test should be performed after adjusting interlock mechanism.
If the microwave emission exceed 4mW/cm , readjust interlock mechanism.

MEASUREMENT AND TEST
1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT
Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed
to the microwave as directed below.
PROCEDURE
1. Microwave power output measurement is made with the microwave oven supplied at rated voltage and operated at its
maximum microwave power setting with a load of 100 5cc of potable water.
2. The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside
diameter of approximately 190mm.
3. The oven and the empty vessel are at ambient temperature prior to the start of the test. The initial temperature of the water is
10 2 (50 3.6 ). It is measured immediately before the water is added to the vessel. After addition of the water to the
vessel, the load is immediately placed on the center of the shelf, which is in the lowest normal position.
4. Microwave power is switched on.
5. Heating time should be exactly A seconds.
(Refer to table as following)
Heating time is measured while the
microwave generator is operating at full power.
The filament heat-up time for magnetron is not included.
6. The initial and final temperature of water is selected
so that the maximum difference between the ambient
and final water temperature is 5K.
7. The microwave power output P in watts is calculated
from the following formula :
P = 4187 X T
T is difference between initial and ending temperature.
t is the heating time.
The power measured should be B (Refer to SPECIFICATIONS) W 10.0%.
CAUTION
1. Water load should be measured exactly to 1 liters.
2. Input power voltage should be exactly specified voltage (Refer to SPECIFICATIONS)
3. Ambient temperature should be 20 2 (68 3.6 )
* Heating time for power output :
A(second) 70 64 60 56 52 49 47 44 42 40 38
B(W) 600 650 700 750 800 850 900 950 1000 1050 1100
29
MEASUREMENT AND TEST
2. MICROWAVE RADIATION TEST
WARNING
1. Make sure to check the microwave leakage before and after repair of adjustment.
2. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy.
3. Do not place your hands into any suspected microwave 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 microwave energy.
5. Slowly approch the unit under test until the radiometer readds an appreciable microwave leakage from the unit
under the test.
PROCEDURES
1. Prepare Microwave Energy Survey, 600cc glass
beaker, and glass thermometer 100 (212 )
2. Pour 275cc 15cc of tap water initially at 20 5
(68 9 ) in the 600cc glass breaker with an inside
diameter of approx. 95mm(3.5in.).
3. Place it at the center of the tray and set in a cavity.
4. Close the door and operate the oven.
5. Measure the leakage by using Microwave Energy Survey
Meter with dual ranes, set to 2450MHz.
1) Measured radiation leakage must not exceed the value
prescribed below. Leakage for a fully assembled oven with
door normally closed must be less than 4mW/cm .
2) When measuring the leakage, always use the 5cm(2 in.)
space cone with probe. Hold the probe perpendicular to
the cabinet and door. Place the space cone of the prove
on the door, cabinet, door seem, door viewing screen, the
exhaust air vents and the suction air vents.
3) Measuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the leakage of the cabinet door seem is
unknown, move the probe more slowly.
4) When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe end at
the base of the cone does not get closer than 2 in. from any metal. If it does not, erroneous reading may result.

MEASUREMENT AND TEST
3. COMPONENT TEST PROCEDURE
High voltage is present at the high voltage terminal of the high voltage transformer during any cooking cycle.
It is neither necessary nor advisable to attempt measurement 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) Remove connections from the transformer terminals and check continuity.
(2) Normal readings should be as follows:
Secondary winding ........................ Approx. 110 10%
Filament winding ............................................... Approx. 0
Primary winding ................................................ Approx. 1
2. High voltage capacitor
(1) Check continuity of capacitor with meter on the hightest OHM scale.
(2) A normal capacitor will show continuity for a short time, and then indicate 10M once the capacitor is charged.
(3) A shorted capacitor will show continuous continuity.
(4) An open capacitor will show constant 10M .
(5) Resistance between each terminal and chassis should be infinite.
3. High voltage diode
(1) Isolate the diode from the circuit by disconnecting the leads.
(2) With the ohmmeter set on the highest resistance scale measure the resistance across the diode terminals.
Reverse the meter leads and again observe the resistance reading.
Meter with 6V, 9V or higher voltage batteries should be used to check the front-back resistance of the diode,
otherwise an infinite resistance amy be read in both directions.
A normal diode’s resistance will be infinite in one direction and several hundred K in the other direction.
4. Magnetron
For complete magnetron diagnosis, refer to “ Measurement of the Microwave Power Output ".
Continuity checks can only indicate and open filament or a shorted magnetron.
To diagnose for an open filament or a shorted magnetron.
(1) Isolate magnetron from the circuit by disconnecting the leads.
(2) A continuity check across magnetron filament terminals should indicate 0.1 or less.
(3) A continuity check between each filament terminal and magnetron case should read open.
5. Fuse
If the fuse in the primary and monitor switch circuit is blown when the door is opened, check the primary and monitor
switch before replacing the blown fuse.
In case the fuse is blown by an improper switch operation, replace the defective switch and fuse at the same time.
Replace just the fuse if the switches operate normally.
