IGNITION
MODULE
Ignition modules are mounted hori-
zontally under the controller box. LED’s
on the modules are guides when diag-
nosing ignition problems.
The yellow-circled LED’s light when
the module gets power.
The red-circled LED’s light as the
module self tests, sparks and locks out.
There’s one
fl
ash with the self test,
two
fl
ashes as it sparks for ignition and
three
fl
ashes if
fl
ame is not sensed and
the module locks out.
Depending on the wiring harness, the
left module will light
fi
rst followed by
the right or the right module will light
fi
rst followed by the left. In all cases,
one module follows the other in the
ignition sequence. To determine which
is locking out, the red LED’s have to
be directly observed by removing the
metal covering over the modules.
