IntelliFire™ Touch - (continued)
Symptom Possible Cause Corrective Action
Pilot sparks for 60 sec, but will not
light, 3 Red/1 Green Lockout.
No gas supply.
Verify incoming gas line ball valve is ‘Open’. Verify inlet pres-
sure is within requirement for gas type used. Contact gas sup-
plier.
ECM has poor ground.
Verify wiring, check valve harness black wire is securely
grounded to metal chassis.
Gas valve defective.
Check pilot valve solenoid kick and hold voltages during igni-
tion cycle. Kick V should be >1 V, hold V minimum 0.26 V. If
voltages are OK, replace gas valve.
Pilot lights but main burner does
not light. Pilot continues to spark
for 60 sec then goes into 3 Red/1
Green Lockout.
No ame detected. Flame
rectication issue.
Check if white sense lead is securely connected to ‘S’ terminal
of IFT-ECM. Check resistance of sense lead between sense
rod tip and connector to IFT-ECM, should be less than 1 ohm
- if not, replace pilot assembly. Check system ground, ensure
black valve harness wire is securely attached to metal chassis.
Check wiring for damage. With system OFF, check resistance
between tip of sense rod and pilot hood, should be resistance
(>1 M-ohm).
No ame detected or sense
rod contamination.
With glass assembly installed, verify pilot ame is engulng
ame sense rod on pilot assembly. Verify inlet gas pressure
is correct for gas type. Polish ame sense rod with ne steel
wool to remove any contaminants that may have accumulated.
Pilot lights and recties, but main
burner does not light.
Main valve solenoid.
Check if green wire in valve harness is connected to green
main valve solenoid. Check main valve solenoid resistance,
nominal is 60 ohms. If open or shorted, replace valve. Verify
valve inlet pressure is correct for gas type.
Appliance lights and runs for a few
minutes then shuts down and/or
appliance cycle ON and OFF with
less than 60 sec of ON time.
Shorted or loose connection in
ame detection circuit.
Check if white sense lead is securely connected to ‘S’ terminal
of IFT-ECM. Check resistance of sense lead between sense
rod tip and connector to IFT-ECM, should be less than 1 ohm
- if not, replace pilot assembly. Check system ground, ensure
black valve harness wire is securely attached to metal chassis.
Check wiring for damage. With system OFF, check resistance
between tip of sense rod and pilot hood, should be resistance
(>1 M-ohm).
Poor ame rectication or
contaminated sense rod.
With glass assembly installed, verify pilot ame is engulng
ame sense rod on pilot assembly. Verify inlet gas pressure
is correct for gas type. Polish ame sense rod with ne steel
wool to remove any contaminants that may have accumulated.
Verify no soot deposits are in sense rod to pilot hood gap.
Logs are set up wrong. Remove and re-install logs per the log placement instructions.
Damaged pilot assembly.
Verify the pilot assembly ceramic insulator around the ame
sensing rod is not cracked, damaged or loose. Check resis-
tance between tip of sense rod and IFT-ECM connector, should
be less than 1 ohm. Replace pilot assembly if damage is de-
tected.
