IGNITION MODULE DIAGNOSTICS
Flame Fault
If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will
detect it and energize the combustion blower. Should the main valve later close completely removing the flame
signal, the combustion blower will power off following the post purge period.
Fault Conditions
The LED located on the ignition module will flash ON
for ¼ second, then OFF for ¼ second during a fault
condition. The pause between fault codes is 3
seconds.
