A. PRIMARY INTERLOCK SWITCH TEST
When the door release button is depressed slowly
with the door closed, an audible
click
should be
heard at the same time or successively at
intervals. When the button is released slowly, 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 leads 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 using only the same type of switch.
B. SECONDARY INTERLOCK SWITCH TEST
Disconnect the wire leads from the secondary
switch.
Connect the ohmmeter leads to the common
(COM) and normally open (NO) terminals of the
switch. The meter should indicate an open circuit
with the door open. When the door is closed,
meter should indicate a closed circuit. When the
secondary switch operation is abnormal, make the
necessary adjustment or replace the switch using
only the same type of switch.
C. MONITOR SWITCH TEST
Disconnect the wire leads from the monitor switch.
Connect the ohmmeter leads to the common
(COM) and normally closed (NC) terminals of the
switch. The meter should indicate a closed circuit
with the door open. When the door is closed,
meter should indicate an open circuit. When the
monitor switch operation is abnormal, replace it
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.
