primary interlock switch terminal.

(2) Connect the ohm-meter leads between the lead wire connector disconnected as item1 and

the power supply neutral plug pin.

(3) Read the value of resistance between the lead wire connector and the power supply neutral plug pin,

when the oven door is opened, and when the oven door is closed.

JUDGEMENT

•
