Adjustment of Primary latch switch, Secondary latch switch
and short switch
1. 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 Figure.
NOTE: No specific adjustment during installation of Primary
latch switch, Secondary latch switch and short switch
to the door hook is necessary.
2. When mounting the door hook assembly to the oven assembly,
adjust the door hook assembly by moving it in the direction of
arrow in Figure 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.
MEASUREMENTS AND ADJUSTMENTS
Measurement of microwave output
The output power of the magnetron can be determined by
performing IEC standard test procedures.
However, it is possible to test the magnetron by following
procedure outlined below.
Necessary equipment:
*1 liter beaker *Glass thermometer
*Wrist watch or stopwatch
NOTE: Check the line voltage under load to ensure it meets
specifications. Low voltage condition will cause a reduction
in magnetron output. Temperature readings and heating
time, should be as accurate as possible.
Output power performance test procedure.
1. Fill the beaker with exactly one litre of tap water. Stir the water
using the thermometer and note the temperature. (Record as T1)
2. Place the beaker in the center of cook plate. Set the oven for
High power and heat for exactly one minute.
3. After completion of the heating cycle, stir the water again with
the thermometer and note the temperature. (Record as T2)
The normal temperature rise (T2-T1), for these models should
be more than 7.0°C using the High power
selection with the oven operating at the specified line voltage.
Please confirm that the gap between the switch housing and
switch actuator lever is no more than 1.0mm when the door
is closed.
