• Disconnect the oven from the power supply.
• You can test continuity of safety interlocks and monitor switch by using switch tester or ohmmeter.
• The switch operation is checked by the lamp on/off of resistance zero/unlimited.
• The sequence of check is interlock monitor switch; primary and secondary interlock switches check.
• Make circuits like Fig. a, Fig. b, tests.
SAFETY INTERLOCK CONTINUITY TEST
1) In case of interlock monitor check.
(Lamp on or zero resistance)
(ohmmeter)
– Fig. a –
Condition: 1) Door is opened.
2) Common terminal of the monitor
switch disconnected.
* (Schematic diagarm of S/W tester)
2) In case of primary interlock check.
(Lamp on or zero resistance)
(ohmmeter)
– Fig. b –
Condition: 1) Door is closed.
