Ignition Control Operation and
Troubleshooting for Models Starting
3/11/13
Before troubleshooting the system, check the
following items:
- Verify all mechanical and electrical connections are
secure and tight.
- Verify all system wiring is correct.
- Verify there is a proper system ground. The igniter,
flame sensor and igniter module must share a common
ground with the burner. Nuisance shutdowns are often
caused by a poor or erratic ground.
- Verify that the system is powered and that the control
is calling for heat.
- If the control proceeds to an error code on the red
diagnostic LED, troubleshoot per the Fault conditions
table below:
NOTE: The LED will flash on for 1/4 second, then
off for 1/4 second during a fault condition. The
pause between fault codes is 3 seconds.
Internal Control Failure
If the control detects an error in its software or
hardware, all outputs are turned off and the red LED
displays a steady ON condition. If this condition
persists after an attempt to restart, then the control
must be replaced.
