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.
(c) Before turning on microwave power for any service test or inspection within the microwave generating
compartments, 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
transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before
the oven is released to the owner.
(e) A microwave leakage check to verify compliance with the Federal per formance standard should be performed
on each oven prior to release to the owner.

The following U.S. standard applies to microwave ovens :

Ovens.
It requires that the power density of the microwave

five (5) milliwatts per square centimeter at any point 5

surface of the oven.
All microwave ovens exceeding the emission level of

the owner should be told not to use the microwave oven
until it has been repaired completely.
If a microwave oven is found to operate with the door open,
report to Dept. of Service, the manufacturer and CDRH*
immediately. Also tell the owner not to use the oven.
*CDRH : Center for Device and Radiological Health.
The interlock monitor switch acts as the final safety switch
protecting the customer from microwave radiation. If the
interlock monitor switch operates properly and the door
interlocks switch fails, the fuse will blow. If this happens,
all interlock switches must be replaced. The contacts of
the interlock switches may be welded together.

in measurement with IEC, when measured with the following
power output.
(1) Fill two beakers ( glass or plastic ) with each one liter
of tap water ( about 20oC ) and measure the water temperature. ( Use a thermometer with a 1/10 degree gauge ).
(2) Place the beakers side by side in the center of the glass
tray.
(3) Close the door, set the “TIME” for two minutes. ( “200”
in the display window. ) Touch the “START” key and
heat the water exactly for two minutes.
(4) Take the beakers out, immediately stir the water and
measure the water temperature respectively.
(5) Calculate the temperature rise of water in each beaker.
Then calculate the average value of two temperature rises.
Output power can be calculated by the equation :
Where ∆t is an average temperature rise in degrees
Centigrade.

(a) Open and close door several times to make sure the
primary interlock switch, the interlock monitor switch
and the door sensing switch operate properly.
(Listen for the clicking sound from the switches.)
Make sure the interlock monitor switch closes after
the primary interlock switch is opens when the door
is opened.(See pages 1 and 6)
(b) Make sure the perforated screen and the choke die-
lectric of the door are correctly mounted.
(2) After the power is applied :
(a) Open and close the door to see if the interlock mech-
anism operates properly.
(b) Check microwave energy leakage with a leakage
detector and confirm the energy leakage should be
no greater than 4mW/cm2 to allow for measurement
uncertainty.
(3) Do not operate the unit until it is completely repaired,
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 microwave

After removing the Blower Motor :
(1) Remove 4 screws and disengage Space Partition.
(2) Disconnect lead wire from the Magnetron.
(3) Remove 4 screws securing the Magnetron to the
Waveguide.
(4) Take out Magnetron VERY CAREFULLY.
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.

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 4mW/cm
