service invoice.

(2) Should the microwave energy leakage not be

more than 1 mW/cm2after determining that all
parts are in good condition, functioning properly
and genuine replacement parts which are listed in
this manual have been used.

(3) At least once a year, have the electromagnetic

energy leakage monitor checked for calibration
by its manufacturer.

(1) Microwave power output measurement is made

with the microwave oven supplied at its rated voltage and
operated at its maximum microwave power setting with a
load of (1000±5) g of potable water.

(2) The water is contained in a cylindrical borosilicate

glass vessel having a maximum material thickness
of 1/8” (3 mm) and an outside diameter of approximately

7.6” (190mm).

(3) The oven and the empty vessel are at ambient

Temperature(T0) prior to the start of the test.

(4) The initial temperature (T1) of the water is

(10±1)°C (50°F) 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 turntable which is in the lowest position and the
microwave power switched on.

(5) The time t for the temperature of the water to rise

by a value T of (10±1)°K is measured, where t is the
time in seconds and T is the temperature rise.
The initial and final water temperatures are selected so
that the maximum difference between the final water
temperature and the ambient temperature is 5°K.

(6) The microwave power output P in watts is calculated

from the following formula :

4,187 Mw(T2 –T1)+0.55Mc(T2 –T0)

t

is measured while the microwave generator is
operating at full power. Magnetron filament heat-up
time is not included. (about 5 sec)

(7) The water is stirred to equalize temperature

throughout the vessel, prior to measuring the final
water temperature.

(8) Stirring devices and measuring instruments are

selected in order to minimize addition or removal of
heat.

ADJUSTMENT PROCEDURES

To avoid possible exposure to microwave energy
leakage, adjust the door latches and interlock
switches, using the following procedure.

The Interlock Monitor and Primary Interlock Switch act
as the final safety switch protecting the user from
microwave energy. The terminals between “COM” and
“NC” of the Interlock Monitor must close when the door
is opened. After adjusting the Interlock Monitor Switch,
make sure that it is correctly connected.
Mounting of the primary/monitor/secondary switches to
the latch board.

CHECK THE DOOR LATCH AND SWITCH
CLOSING.

NOTE:

The outer cover of the microwave oven is
removed.

(1) Set the microwave oven on its side so that you can

see the latch board and the switches, as shown in
Figure 25-a.

(2) Close the door tightly and check gaps A and B to

be sure they are no more than 1/64” (0.5 mm).
See Figure 25-b for close-up view of gaps A and B
(door latches). If all gaps are less than 1/64”
(0.5 mm), adjustment of the latch board may not
be necessary. Go to Steps 5 and 6 to check the
sequence of the switches.

NOTE:

To correct sequence of the Primary Interlock
Switch, Secondary Interlock Switch and the
Interlock Monitor Switch is very important.

If any gap is larger than 1/64” (0.5 mm), you will

need to adjust the latch board”. Go to step 3
and follow all steps in order.

ADJUST THE LATCH AND SWITCH CLOSING

(3) Loosen the two screws holding the plastic latch

board as shown.

(4) With the oven door closed tightly, move the latch

board upward toward the top of the oven and/or

away from the door latch until the gaps are less

than 1/64” (0.5 mm).
Hold the latch board tightly in this position until you
check the sequence of the switches in steps 5
and 6.

INTERLOCK SYSTEM

INTERLOCK MECHANISM

The door lock mechanism is a device which has been specially designed to eliminate completely microwave
activity when the door is opened during cooking and thus to prevent the danger resulting from the microwave
leakage.

7-12

TEST THE LATCH AND SWITCH SEQUENCE

(5) Open the oven door slowly. Watch the door latch,

the Secondary Switch. Release Rod and Lever
on the switches to make sure they are zero to the
body of the switches in the following sequence:

- Primary Interlock Switch

- Secondary Interlock Switch

- Interlock Monitor Switch

Adjust the latch board until the switches operate in
this sequence. See Steps 3 and 4.

(6) Close the oven door slowly and be sure it is tightly

closed. Watch the three switches to make sure
they are zero to the body of the switches in the
following sequence:

- Interlock Monitor Switch

- Primary Interlock Switch

- Secondary Interlock Switch

NOTE: The Interlock Monitor Switch is an added

safety check on the Primary and
Secondary Interlock Switches. If the
Primary and Secondary Interlock Switches
allow the oven to operate with the door
open, the Monitor Switch will blow the
fuse.

(7) When you achieve the proper sequence of

switches in Steps 5 and 6, tighten the latch board

screws at that point.

TEST THE MICROWAVE ENERGY LEAKAGE

Make sure the microwave energy leakage is below the
limit of 1mW/cm2 (with a 275 ml water load) and
5mW/cm2 (with a 275 ml water load without the
cabinet) when measured with a survey meter.

7-13

A. PRIMARY INTERLOCK SWITCH TEST

When the door is opened slowly, an audible click
should be heard at the same time or successively
at intervals and the latches should activate the
switches with an audible click.
If the latches do not activate the switches when the
door is closed, the switches should be a adjusted
in accordance with the adjustment procedure.
Disconnect the wire lead from the primary switch.
Connect the ohmmeter leads to the common
(COM) and normally open (NO) terminal of the
switch. The meter should indicate an open circuit
in the door open condition.
When the door is closed, the meter should indicate
a closed circuit.
When the primary switch operation is abnormal,
make the necessary adjustment or replace the
switch only with the same type of switch.

B. SECONDARY INTERLOCK SWITCH TEST

Disconnect the wire lead from the secondary

switch.

Connect the ohmmeter leads to the common

(COM) and normally open (NO) terminals of the

switch. The meter should indicate a open circuit in

the door open condition. When the door is closed,

meter should indicate an closed circuit. When the

secondary switch operation is abnormal, make the

necessary adjustment or replace the switch only

with the same type of switch.

C. MONITOR SWITCH TEST

Disconnect the wire lead from the monitor switch.

Connect the ohmmeter leads to the common

(COM) and normally closed (NC) terminals of the

switch. The meter should indicate closed circuit in

the door open condition. When the door is closed,

meter should indicate an open circuit. When the

monitor switch operation is abnormal, replace with

the same type of switch.

NOTE: After repairing the door or the interlock

system, it is necessary to do this continuity

test before operating the oven.

WARNING : FOR CONTINUED PROTECTION AGAINST EXCESSIVE RADIATION

EMISSION, REPLACE ONLY WITH IDENTICAL REPLACEMENT PARTS.
