• Flame LED (Yellow)
— Indicates flame presence and strength. See
Table 13.
• Status LED (Green)
— Indicates system operation status and error condi-
tions. See Table 14 and the “Troubleshooting
Guide” on page 21.

Yellow LED
Flash Code
a
a
Flash Code Descriptions:
- Heartbeat: Constant ½ second bright, ½ second dim cycles.
- The flash code number signifies that the LED flashes X times at 2 Hz, remains off for two seconds, and then repeats the sequence.
Indicates Recommended Service Action
Heartbeat Normal Flame Signal Not applicable
2 Weak Flame Signal—System will operate reliably but flame signal is
less than desired.
NOTE: This indication may flash temporarily during or shortly after
lightoff on some applications.
Perform routine maintenance to assure optimum flame
signal.
1 Marginal Flame Signal—System may not operate reliably over time.
Service call recommended.
NOTE: This indication may flash temporarily during or shortly after
lightoff on some applications.
Check gas supply, pilot burner, flame sense wiring,
contamination of flame rod, burner ground connection.
OFF Flame Signal below minimum threshold for system operation Check gas supply, pilot burner, flame sense wiring,
contamination of flame rod, burner ground connection.

Flash Code Descriptions:
- Flash Fast: rapid blinking.
- Heartbeat: Constant ½ second bright, ½ second dim cycles.
- A single flash code number signifies that the LED flashes X times at 2 Hz, remains off for two seconds, and then repeats the
sequence.
- X + Y flash codes signify that the LED flashes X times at 2 Hz, remains off for two seconds, flashes Y times at 2Hz, remains off for
three seconds, and then repeats the sequence.
Indicates Next System Action Recommended Service Action
OFF No “Call for Heat” Not applicable None
Flash Fast Startup - Flame sense calibration Not applicable None
Heartbeat Normal operation Not applicable None
2 5 minute Retry Delay
– Pilot flame not detected during
trial for ignition
Initiate new trial for ignition after retry delay
completed.
If system fails to light on next trial for ignition
check gas supply, pilot burner, spark and flame
sense wiring, flame rod contaminated or out of
position, burner ground connection.
3 Recycle
– Flame failed during run
Initiate new trial for ignition. Flash code will remain
through the ignition trial until flame is proved.
If system fails to light on next trial for ignition,
check gas supply, pilot burner, flame sense
wiring, contamination of flame rod, burner ground
connection.
4 Flame sensed out of sequence If situation self corrects within 10 seconds, control
module returns to normal sequence. If flame out of
sequence remains longer than 10 seconds, control
module goes to Flash code 6+4 (see below).
Check for pilot flame. Replace gas valve if pilot
flame present. If no pilot flame, cycle “Call for
Heat.” If error repeats, replace control.
5 Damper Error:
– Damper required but not present
– Damper failed to open within 60
seconds
– Damper failed to close within 60
seconds
If damper error corrects, ignition control resumes
normal operation.
Check damper connection, damper wiring, and
24V connection on control.
Replace damper if necessary.
7 Flame sense leakage to ground Control module remains in wait mode. When the fault
corrects, control module resumes normal operation
after a one minute delay.
Check flame sense lead wire for damage or
shorting. Check that flame rod is in proper
position. Check flame rod ceramic for cracks,
damage or tracking.
8 Low secondary voltage supply Control module remains in wait mode. When the fault
corrects, control module resumes normal operation
after a one minute delay.
Check transformer and AC line for proper input
voltage to the control. Check with full system load
on the transformer.
6+2 5 minute Retry Delay
– On every third retry on the same
“Call for Heat”
Initiate new trial for ignition after retry delay
completed.
Check gas supply, pilot burner, spark and flame
sense wiring, flame rod contaminated or out of
position, burner ground connection.
6+3 On every 6th flame failure during
run on the same “Call for Heat”
Initiate new trial for ignition after retry delay
completed.
Check gas supply, pilot burner, flame sense
wiring, contamination of flame rod, burner ground
connection.
6+4 Flame sensed out of sequence for
longer than 10 seconds
Control module waits until flame is no longer sensed
and then goes to soft lockout. Flash code continues.
Control module auto resets from soft lockout after one
hour.
Check for pilot flame. Replace gas valve if pilot
flame present. If no pilot flame, cycle “Call for
Heat.” If error repeats, replace the S8610U
control module.
ON Soft lockout due to error detected
during self check sequences
Control module auto resets from soft lockout after one
hour.
Reset by cycling “Call for Heat.” If error repeats,
replace the S8610U control module.
