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 recti
fi
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
fl
ame sense or igniter wires are not grounding out to metal
chassis, pilot burner, pilot enclosure or screen if present, or
any other metal object.
B. Poor
fl
ame recti
fi
cation or contaminated
fl
ame sensing rod.
With
fi
xed glass assembly in place, verify that
fl
ame is en-
gul
fi
ng
fl
ame sensing rod on left side of pilot hood. Flame
sensing rod
should glow shortly after ignition. With a multi-
meter, verify that current in series between module and
sense lead is at least 0.14 microamps. Verify correct pilot
ori
fi
ce is installed and gas inlet is set to pressure speci
fi
-
cations. Polish
fl
ame sensing rod with
fi
ne steel wool 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. Polish
fl
ame sens-
ing rod with
fi
ne steel wool to remove any contaminants
that may have accumulated on
fl
ame sensing rod. Verify
continuity with a multi-meter with ohms set at lowest range.
Replace pilot if any damage is detected.
5. Appliance lights and
runs for a few minutes
and then shuts down
and/or appliance cycles
on and off.
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
fl
ame sense or igniter wires are not grounding out to metal
chassis, pilot burner, pilot enclosure or screen if present, or
any other metal object.
B. Poor
fl
ame recti
fi
cation or contaminated
fl
ame sensing rod.
With
fi

ame is en-

fl
ame sensing rod with
fi
ne steel wool to
remove any contaminants that may have accumulated on
fl
ame sensing rod.
C. Logs are set up incorrectly.
Remove and reinstall logs per the log placement
instructions.
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. Polish
fl
ame sens-
ing rod with
fi
ne steel wool to remove any contaminants
that may have accumulated on
