Intellifi re Ignition System - (continued)
Symptom
Possible Cause
Corrective Action
4. Pilot lights but contin-
ues to spark, and main
burner will not ignite.
(If the pilot continues
to spark after the
pilot fl ame has been lit,
fl ame rectifi cation has
not occurred.)
A. A shorted or loose connection in fl ame
sensing rod.
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify con-
nections are not grounding out to metal chassis, pilot burn-
er, pilot enclosure or screen if present, or any other metal
object.
B. Poor fl ame rectifi cation or contaminated
fl ame sensing rod.
With fi xed glass assembly in place, verify that fl ame is en-
gulfi ng fl ame sensing rod on left side of pilot hood. Flame
sensing rod
should glow shortly after ignition. Verify cor-
rect pilot orifi ce is installed and gas inlet is set to pressure
specifi cations. Clean fl ame sensing rod with emery cloth to
remove any contaminants that may have accumulated on
fl ame sensing rod.
C. Module is not grounded.
Verify module is securely grounded to metal chassis of ap-
pliance. Verify that wire harness is fi rmly connected to the
module.
D. Damaged pilot assembly or contami-
nated fl ame sensing rod.
Verify that ceramic insulator around the fl ame sensing rod
is not cracked, damaged, or loose. Verify connection from
fl ame sensing rod to white sensor wire. Clean fl ame sensing
rod with emery cloth to remove any contaminants that may
have accumulated on fl ame sensing rod. Verify continuity
with a multimeter with ohms set at lowest range. Replace
pilot if any damage is detected.
E. Module.
Turn ON/OFF rocker switch or wall switch to OFF position.
Remove ignitor wire “I” from module. Place ON/OFF rocker
switch or wall switch in ON position. If there is no spark at “I”
terminal module must be replaced. If there is a spark at “I”
terminal, module is fi ne.
