WARNING
1. Adjustment of Primary latch switch, Second-
ary latch switch and Short switch.
(A) When mounting Primary latch switch,Secondary latch switch
and short switch to door hook assembly, mount the Primary latch
switch, the Secondary latch switch and the short switch to the
door hook assembly as shown in table.
NOTE: No specific adjustment during installation of
Primary latch switch, Secondary latch switch and
short switch to the door hook is necessary.
(B) When mounting the door hook assembly to the oven
assembly, adjust the door hook assembly by moving it in the
direction of arrow in the illustration so that the oven door will not
have any play in it. Check for play in the door by pulling the door
assembly. Make sure that the latch keys move smoothly after
adjustment is completed. Completely tighten the screws holding
the door hook assembly to the oven assembly.
(C) Reconnect the short switch and check the continuity of the
monitor circuit and all latch switches again by following the
components test procedures.
2. Measurement of microwave output
The output power of the magnetron can be determined by performing
IEC standard test procedures. However,due to the complexity
of IEC test procedures, it is recommended to test the magnetron
using the simple method outlined below.
Necessary Equipment:
*1 liter beaker *Glass thermometer
*Wrist watch or stopwatch
NOTE: Check the line voltage under load.Low voltage will
lower the magnetron output. Take the temperature
readings and heating time as accurately as possible.
(A) Fill the beaker with exactly one liter of tap water.Stir the water
using the thermometer and record the beaker’s temperature.
(recorded as T1).
(B) Place the beaker on the center of glass cook plate.
Set the oven for High power and heat it for exactly one minute.
(C) Stir the water again and read the temperature of the beaker.
(recorded as T2).
(D) The normal temperature rise at High power position for each
model is as shown in table.

For continued protection against radiation hazard,
replace only with identical replacement parts(For touch
models Part No. ANE6142-1450,Type No.
V-16G-3C26-M for Primary latch switch; Part No.
A61425180AP, Type No. L-3C2-2 for Secondary latch
switch; Part No. A61785180AP, Type No. L-2C2-2 for
short switch and Part. No. AEG5J1EG12B/AEG5J1EG18B,
Type No. G5J-1-TP for power relay B(RY1))
*
When the 18 Amp. fuse is blown due to the operation of
the short switch, you must replace power relay B.
Primary
latch switch and the short switch. Then follow the installa-
tion procedures below.
*
Interlock switch replacement In replacing faulty
switches, be sure mounting tabs are not bent, broken or
otherwise deficient in their ability to hold the switches.
*
Refer to schematic diagram to ensure proper connec-
tion.
