Component
Disconnect connector and test
resistance of terminals........................
Measure voltage at oven light.............
Measure voltage at:
Primary terminals ............................
Secondary terminals .......................
Remove switch from unit and
measure the following points:
COM to NO ..................................... Plunger in continuity, plunger out
Disconnect wires and test for
continuity per wiring diagram..............
Refer to Parts Manual for correct
autolatch switch associated with the
correct manufacturing number.
Verify gas pressure (W.C.P.)..............
If on LP service verify proper gas
supply conversion.
Verify gas is supplied.
