WARNING
Component Test Procedure
Remove one wire from receptacle
and test resistance of terminals........
Measure voltage at oven light...........
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 is supplied.
Adjust set screw for simmer control.
Test for voltage at terminals .............
Disconnect wiring and check for
continuity in LITE position.................
Test for resistance of spark lead ......

Verify gas is supplied .......................
Verify burner cap is positioned
correctly.
Test for voltage at terminals L and N
Check polarity and ground................
Measure resistances ........................
Verify gas pressure (W.C.P.).
If on LP service verify proper gas
supply conversion.
Remove switch from unit and
measure the following points:
