Symptom

Possible Cause

Corrective Action

Pilot sparks but does not light, after  

90 sec, 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 90 sec then goes into 3 Red/1 

Green Lockout.

No flame detected. Flame 

rectification 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 flame detected or sense 

rod contamination. 

With  glass  assembly  installed,  verify  pilot  flame  is  engulfing 

flame sense rod on pilot assembly.  Verify inlet gas pressure 

is correct for gas type.  Polish flame sense rod with fine steel 

wool to remove any contaminants that may have accumulated.

Pilot lights and rectifies, 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.

Pilot and main do not light, ECM 

goes into 5 Red/1 Green Lockout.

Power Vent (PV) Failure.

Power Vent blower defective - check wiring to 

IFT-

ACM, check 

if blower is working.  Check if PV pressure switch is connected 
to brown and black wire in 6-pin valve wire harness.  Check if 
pressure switch is closed (shorted) when PV blower is running.  
Refer to PV troubleshooting instructions. 

Appliance lights and runs for a few 

minutes then shuts down and/or 

appliance cycle ON and OFF with 

less than 90 sec of ON time. 

Shorted or loose connection in 

flame 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 flame rectification or 

contaminated sense rod. 

With  glass  assembly  installed,  verify  pilot  flame  is  engulfing 

flame sense rod on pilot assembly.  Verify inlet gas pressure 

is correct for gas type.  Polish flame sense rod with fine 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  flame 

sensing  rod  is  not  cracked,  damaged  or  loose.    Check  re

-

sistance between tip of sense rod and 

IFT-

ECM  connector, 

should be less than 1 ohm.  Replace pilot assembly if damage 
is detected.
