8.1. 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 table.
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 table 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.
3. Reconnect the short switch and check the continuity of the
monitor circuit and all latch switches again by following the
components test procedures.
8.2. Measurement of microwave
output
The output power of 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 accurate as possible.
1. 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)
2. Place the beaker on the center of glass cook plate. Set the
oven for High power and heat it for exactly one minute.
3. When one minute is elapsed, open the door and take out
beaker.
4. Stir the water again and read the temperature of the beaker
(recorded as T2).
5. The normal temperature rise at High power position for
each models is as shown in table.
