Pilot flame too low.
Pilot ignited but control panel will not turn on.

PROBLEM: OVEN TURNS OFF DURING OPERATION - (Continued)
TROUBLESHOOTING
Corrective Action
24VAC not measured. Turn off oven power and replace
igniter module. See page 8-51.
When oven power is turned on, there is high
voltage present in the electrical components
compartment.
No spark observed. Turn on oven power. Refer to
schematic diagram and check for 24VAC at igniter module
terminals 24V-1 and 24V-2.
24VAC measured. Turn off oven power and:
• Check large orange wire from igniter module to pilot
burner for continuity, and for insulation breaks. Replace
wire if necessary.
• Clean spark electrode and hood of pilot burner.
• Check pilot runner tube. Clean or replace if necessary.
See page 8-57.
• Check spark gap. Clean and regap if necessary.
• Check if pilot burner is wet. Dry pilot burner if necessary.
• Replace igniter module. See page 8-51.
24VAC not measured. Turn off oven power and discon-
nect oven from branch circuit.
• Place pilot switch SW1 in the ON position. Check switch
continuity. Replace switch if meter indicates an open
circuit.
• Continuity check SW1-to-igniter module wiring. Replace
defective wire and wire terminal.
Check pilot flame current. (See page 8-9.)
Adjust pilot flame. (See page 8-10.)
Turn on oven power and check for 115VAC at the relay
board power input terminals. Refer to the schematic dia-
gram on page 4-19 or 5-19.
Contact Check
If 115VAC is measured, perform power supply check. See
page 8-3.
If 115VAC is not measured, check for 115VAC between
pilot detect relay terminals CR1-4 and CR1-7.
