MEASUREMENTS AND ADJUSTMENTS
WARNING
For continued protection against radiation hazard,
replace only with identical replacement parts (For
touch models Part No. A6142-1450, Type No. V-
16G-3C26-M for Primary latch switch Part No.
A61425180AP, Type No. L-3C2-2 for Secondary
latch switch and Part No. A61785180AP, Type No.
L-2C2-2 for short switch.)
When the 10 Amp. fuse is blown due to the operation
of the short switch, you must replace primary latch
switch and short switch. Also replace power relay B
(Part.No. AEG5J1 EG12BIAEG5Jl EG18B, Type No.
G5J-1-TP) when the continuity check reads shorted
contacts (1-2). Then follow the adjustment
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
connection
1.
Adjustment of Primary latch switch,
Secondary 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 litre beaker, *Glass thermometer, *Wrist watch or stopwatch
NOTE: Check the line voltage under Ioad. 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 litre of tap water. Stir the
water using the thermometer and record the beaker's temperature. (recorded as T1).
