Test continuity of receptacle terminals...................
Measure voltage at oven light................................
Measure continuity of switch positions:
Closed ...................................................................
Open .....................................................................
Verify gas is supplied.............................................
Verify air shutter opening.......................................
Verify proper orifice installed for Natural or LP.
Check for damage .................................................
Test for voltage at terminals .................................
Test for the amount of amperage in the circuit......
(Ignitor may glow, but not have sufficient
amperage to open valve).
Measure resistance. .............................................. Approximately 1100 Ω at room
Verify gas pressure (WCP) ....................................
If on LP service, verify proper gas supply
conversion.
Disconnect wiring to valve.
Measure resistance on oven burner circuit ............ Continuity
Check to verify gas supply is turned on (shown
in the OPEN position) ............................................ Verify valve does not leak.
Function
Press and hold Clock pad until SET TIME
flashes in the display. Within 30 seconds,
initially press one of the slew up or slew down
pads. Continue to press the appropriate slew
pad(s) until the correct time displays.
Press the Bake pad until 0:00 and BAKE is
displayed. Press the slew up pad until 350° F is
displayed, then use the slew up and slew down
pads to set the desired bake temperature (170°
to 550° F ± 25° F).
Press the Broil pad until 0:00 and BROIL is
displayed. Use the slew up and slew down
pads to enter the appropriate broil temperature
range (LO or HI).
Press the Off/Cancel pad.

WARNING
Do not attempt to open valve with
120 VAC.
Results
Sets the Time-of-Day clock.
Oven begins bake operation after a
four-second delay. Bake function will
automatically cease after 12 hours.
Oven begins broil operation after a four-
second delay. Broil function will
automatically cease after 12 hours.
Cancels all oven functions except the
timer and clock.
