Procedure
Results
Oven light socket
Measure voltage at oven light ....................
Remove one wire from receptacle and
test resistance of terminals ........................
120 VAC, see wiring diagram for terminal
identification.
Continuity with bulb inserted.
If voltage is not present at oven light,
check wiring or light switches.
Manual latch
assembly with
switch
(select models)
Disconnect wires and test for continuity
per wiring diagram .....................................
See wiring diagram for schematic layout.
Refer to Parts Manual for replacement
components.
NOTE:
If latched is moved to LOCK
position during Bake or Broil, the control
cancels the function.
Rocker switch
Measure continuity of switch positions:
Closed....................................................
Open ......................................................
Continuity
Infinite
COM
NO
NC
Door lock switch
Switch connection in following positions: ...
Not
engaged...........................................
Engaged.................................................
Normally Open
COM – NO = Open, COM – NC = Closed
COM - NO = Closed, COM - NC = Open
Bake burner
Verify gas is supplied.
Verify proper orifice installed-Nat or LP .....
Check for obstructions, contamination
in ports or damage.....................................
Air shutter opening: .469" to .531".
Blue flame with no yellow tipping.
Replace if punctured or torn.
Broil burner
Verify gas is supplied.
Verify proper orifice installed-Nat or LP .....
Check for obstructions, contamination
in ports or damage.....................................
Air shutter opening: .281" to .343".
Blue flame with no yellow tipping.
Replace if punctured or torn.
Ignitor
Test for voltage at terminals.......................
Test for amount of amperage in circuit.......
(Ignitor may glow, but not have sufficient
amperage to open valve.)
120 VAC
3.2 to 3.6 Amps.
Temperature sensor Measure resistance ................................... Approximately 1000
Ω
at room
temperature 80
°
F.
Pressure regulator
Verify gas pressure (WCP)........................
If using LP service, verify proper gas
supply conversion.

Shutoff valve
Verify gas supply is turned on....................
Adjust set screw for simmer control.
Gas ON: ..... Slot at 9 o’clock position
Gas OFF: ... Slot at 12 o’clock position
Safety valve
Disconnect wiring to valve.
Measure resistance on bake circuit ...........
Measure resistance on broil circuit ............
Continuity
Continuity
Do not attempt to open valve with
120 VAC.
Spark ignition
electrode
Test for resistance of spark lead................
Test ignitor to chassis................................
Continuity
No continuity from ignitor to chassis.
