1.

Check for 24 volts at the spark ignitor from the ignition 
control board (ICB). Check the 24-volt wiring from the 
ICB to the spark ignitor. Check for 24 volts at the ICB 
spark ignitor terminal.

2.

Check the ground wiring for the ICB and the gas valve is 
intact and making good electrical connection.  Check the 
ceramic insulator on the spark ignitor for breaks or 
cracks.  Replace the spark ignitor if damaged.

3.

With the draft motor running, check for 24 volts at the 
pressure switch terminal on the ICB.  If not present, 
check for 24 volts on the terminal from the pressure 
switch.  If present, go to step 4.  If 24 volts is not present, 
the either pressure or rollout switch is not closed.  Or the 
draft motor is not sufficiently evacuating the heat 
exchanger tubes or the pressure switch has failed.  
Check the operation of the pressure switch.  Check the 
line voltage to the unit; if line voltage is low, call the local 
power company.  If the problem persists, the draft motor 
may need replacement.

4.

If the furnace is hot, it may be out on a high temperature 
limit open; wait for limit reset.

5.

If all are intact replace the ICB.

The draft motor runs and the spark ignitor sparks at the
burner, but the burner does not ignite and a gas odor is not
detected at the draft motor outlet.

1.

Check to ensure gas is being supplied to the unit.  Con-
firm that the gas pressure to the unit is within the proper 
limits as described in the “POST START CHECKLIST”.

2.

Check the voltage at the gas valve and at the gas valve 
terminals on the ICB.  Check all wiring between the ICB 
and the gas valve.  Check to make sure the ground con-
nections are intact.

3.

If 24 volts is present, remove the pilot burner and the ori-
fice.  The removal procedure is described in 
“BURNER/ORIFICE INSTRUCTIONS.”  Inspect the ori-
fice for obstruction.  If it is clear, replace the gas valve.

Main burners light but exhibit erratic flame characteristics.

4.

Check the main burner orifices for obstruction and align-
ment. The removal procedure is described in 
“BURNER/ORIFICE INSTRUCTIONS.” Clean or replace 
burner orifices and burners as needed.
