operation.
Relay board or control panel.
7-10
Corrective Action
Coil Check
If 115VAC is not measured, refer to schematic diagram
(page 4-19 or 5-19), disconnect oven from branch circuit,
and continuity check wiring. Replace a defective wire
and/or wire terminal.
If 115VAC is measured, check for 24VAC between CR1-A
and CR1-B.
Perform CR1 coil continuity check.
24VAC measured at the coil. Turn off oven power and
replace pilot detect relay CR1.
24VAC not measured at the coil. Check for 24VAC
between igniter terminals MV and MV-PV. Refer to
schematic diagram on page 4-19 or 5-19.
If 24VAC is measured, turn off oven power and check for a
wiring problem between CR1 and the igniter module.
Replace broken wire and/or terminal.
If 24VAC is not measured between MV and MV-PV,
replace igniter module. See page 8-51.
Corrective Action
Review operator's manual with owner.
Check that lead on capacitor C101 on relay board
is not touching adjacent diode lead. Separate leads
if necessary.
Perform power supply check. See page 8-3.
