SERVICE MANUAL Microwave Oven EM-C950 (~’ 0,
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 EX-
CESSIVE MICROWAVE ENERGY
(a) Do not operate or allow the oven to be operated with the door open.
(b) Make the followlng safetv 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 closlnq, (31 seal and sealing surfaces (arcing, wear, and other damage), (4)
damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.
(c) Before turning O(I microwave power for any service test or InspectIon wlthtn the microwave generating compartments,
check the magnetron, wave gu!de 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 trans.
mission systems shall be repaired, replaced, or adjusted by procedures described In th!s manual before the oven IS released
to the owner

CAUTION
MICROWAVE RADIATION
PERSONNEL SHOULD NOT BE EXPOSED TO THE
MICROWAVE ENERGY WHICH MAY RADIATE
FROM THE MAGNETRON OR OTHER MICRO-
WAVE GENERATING DEVICE IF IT IS impro-
perly USED OR CONNECTED. ALL INPUT AND
OUTPUT MICROWAVE CONNECTIONS, WAVE-
GUIDES, FLANGES, AND GASKETS MUST BE
SECURE. NEVER OPERATE THE DEVICE WITH-
OUT AMICROWAVE ENERGY ABSORBING
LOAD ATTACHED. NEVER LOOK INTO AN
OPEN WAVEGUIDE OR ANTENNA WHILE THE
DEVICE IS ENERGIZED.
1. ADJUSTMENT PROCEDURES
TO AVOID POSSIBLE EXPOSURE TO MICROWAVE
ENERGY LEAKAGE, THE FOLLOWING ADJUST-
MENT OF THE INTERLOCK SWITCHES SHOULD BE
MADE ONLY BY AUTHORIZED SERVICE PERSON-
NEL.
PRIMARY INTERLOCK SWITCH, SECONDARY
INTERLOCK SWITCH, INTERLOCK MONITOR
SWITCH AND DOOR SENSING SWITCH
ADJUSTMENT
(Figure 1)
(1) Loosen 2screws securing the lever stopper.
(2] Adjust the lever stopper position so that it IS pushed
forward and pull backward until thele IS about zero
gap
2,1 Beween the latch lever and the switch
bodies on the secondary interlock switch
and the door sensing swich.

body on the interlock monitor switch
2.3 Beween the latch lever and the switch
body on the primary interlock switch
when the door latch is securelv locked.

(5)
Tighten the lever stopper screws securely.
Make sure the interlock monitor switch closes after
the primary interlock switch opens when the door
IS opened very slowly, according to “CHECKOUT
PROCEDURE FOR SWITCHES” on page 6,
Make sure the interlock monitor switch opens
before the primary interlock switch closes when the
door is closed very slowly, according to “CHECK-
OUT PROCEDURE F,OR SWITCHES” on page 6.
(6) Make sure the microwave energy leakage is below
the limit of the regulations (5mW/cm2 )when
measured with adetector.
(All service adjustments must be made for minimum
micro wave energy leakage readings. )

4. PRECAUTIONS AND REPAIR SERVICE TIPS
PRELIMINARY
A. SINCE NEALY 4,000 VOLTS EXIST IN SOME
CIRCUITS OF THE MICROWAVEOVENS,
REPAIRS SHOULD BE CARRIED OUT WITH
GREAT CARE.
B.TO AVOID POSSIBLE EXPOSURE TO MICRO-
WAVE ENERGY LEAKAGE, THE FOLLOWING
PRECAUTIONS MUST BE TAKEN BEFORE
SERVICING.
(1) Before the power is applied:
(a) Open and close the door several times to make
sure the primary interlock switch, the secondary
interlock switch, the interlock monitor switch
and the door sensing switch operate properly.
listen for the cliking sound from the switches.
Make sure the interlock monitor switch is
closed after the primary interlock switch is
opened when the door is opened.
(See pages 1 and 6)
(b) Make sure the perforated screen and the choke di-
electric of the door are correctly mounted.
(2) After the power is applied:
(a) Open and close the door to see If the interlock
mechanism operates properly.
(b) Check microwave energy leakage with aleakage
detector and confirm the energy leakage is below 5
mW/cm2 ).
(3) Do not operate the unit until it is completely repair-
ed, if any of the following conditions exists.
(a) Door does not close firmly against the cavity front.
(b) The hinge is broken.
(c) The choke dielectric or the door seal is damaged.
(d) The door is bent or warped, or there is any other
visible damage to the oven that may cause micro-
wave energy leakage.
(e) Make sure that there are no defective parts in the
interlock mechanism.
(f) Make sure there are no defective parts in the micro-
wave generating and transmission assembly. (espe-
cially waveguide).
(4) Following items should be checked after the unit is
repaired.
(a) The interlock monitor switch is connected correctly
and firmly.
(b) The magnetron gasket on the magnetron IS properly
positioned.
(c) Waveguide and oven cavity are intact (no leakage of
microwave energy).
(d) The door can be Properly closed and the safety
switches work Properly.
(e) The oven must be stopped when the door is opened
or the time is up
The oven must not be operated with any of the above
components removed or bypassed.
HINT FOR LAMP CHANGE
Before removing the cabinet, pull out the main plug.
If you want to check the new lamp with the oen
cabinet, take care of the following safety cautions.:
Do not touch live parts, The lamp holder is not connected
to the earth wotecton lead bv ametric screw.

Remove the 8A fuse with ascrewdriver.
NOTES
–When replacing the 8A fuse, be sure to use an
exact repair part.
-- If the 8A fuse blows immediately, check the
primary interlock switch, the relay 2(on the control
circuit board) and the interlock monitor switch
according to “CHECKOUT PROCEDURE FOR
SWITCHES” on page 6. And make sure to check the
microwave energy leakage according to “1, AD-
JUSTMENT PROCEDURES” on page 1, when the
primary interlock switch, the relay 2or the inter-
lock monitor switch is adjusted or replaced.
—If the primary interlock switch, the relay 2and
the interlock monitor switch operate properly,
determine which of the followings is defective:
control circuit board, blower motor, gear motor,
high voltage transformer, high voltage capacitor,
high voltage diode or magnetron.
—If the high voltage diode is defective, replace not
only the high voltage diode but also the fuse diode.

(1) Remove 2upper screws and 3 bottom screws
securing the plastic frame.
(2) Remove 2bolts securing the upper hinge.
(3) Tilt the top of the door toward you,
(4) Lift up the door to remove it.
NOTES
–After replacing the door, be sure to check that
the primary interlock switch, the door sensing
switch and, the interlock monitor switcl~ operate
normally. (See page 1)
–After replacing the door, check for microwave
energy leakage with aleakage detector, Microwave
energy leakage must be below the limit of 5mW/
