LED STATUS INDICATES CHECK/REPAIR
OFF No power to system control. 1. Line voltage input power at L1 and L2 connectors on Terminal
Board.
2. Low voltage (24V) power at 24VAC and COM terminals on
Terminal Board.
3. System wiring harness in good condition and securely connected
at both ends.
4. Electrical supply is live and functioning properly.
Bright-Dim Normal Operation.
This indication shows whenever the system is
powered, unless some abnormal event has
occurred. Not applicable.
2 Flashes Airflow proving switch remains closed longer than
30 seconds after a call for heat begins.
Combustion air blower is not energized until
airflow proving switch opens. 1. Airflow proving switch stuck closed.
2. Airflow proving switch miswired or jumpered.
3 Flashes Airflow proving switch remains open longer than
30 seconds after combustions air blower
energized
System goes into 5-minute delay period, with
combustion air blower off. At the end of the 5-
minute delay, another ignition cycle will begin. 1. Ignition system control switch must be in the ON position.
2. Airflow proving switch operation, tubing, and wiring.
3. Obstructions or restrictions in appliance air intake or exhaust flue
system that prevent proper combustion air flow.
4 Flashes Limit string open.
Combustion air blower is energized. If control
system indicates Electronic Fan Timer, the heat
speed circulating air fan will be energized until the
limit string resets. 1. Open manual reset or auto reset burner rollout switch.
2. Open high temperature or auxiliary limit switch.
3. Limit and rollout switch wiring in good condition and securely
connected.
5 Flashes Flame signal sensed out of proper sequence.
Combustion air blower is energized. If control
system indicates Electronic Fan Timer, the heat
speed circulation air fan will be energized after
the selected heat fan on delay. Flame at main burner.
6 Flashes System lockout.
After 1 hour lockout reset delay, control will reset
and initiate a new ignition sequence if the call for
heat is still present. 1. Gas supply off or at too low pressure to operate appliance.
2. Damaged or broken HSI element.
3. Line voltage HOT leadwire not connected to L1 terminal on
Terminal Board.
4. Appliance not properly earth grounded.
5. Flame sense rod contaminated or in incorrect position.
6. HSI element located in incorrect position.
7. Hot surface element or flame sense rod wiring in good condition
and properly connected.
IF AND CHECK / REPAIR

30 seconds. Wait for prepurge time to expire.
3 Flash code comes on
30 seconds after
combustion air blower
is energized. Combustions air blower turns off. 1. Ignition system control switch must be in the ON position.
2. Airflow proving switch stuck in open position.
3. Airflow proving switch tubing and wiring.
4. Obstruction or restrictions in appliance air intake or
exhaust flue system that prevent proper combustion air
flow.
Prepurge time has
expired. HSI Element does not glow red within
10 to 15 seconds. 1. Broken or damaged HSI element.
2. Broken or damaged HSI element leadwires.
3. Failure to power HSI element.
HSI elements is glowing
red No other visible control system
action. Wait for HSI element warm up time to expire.
