8.8. Honeywell Burner Control Fault Codes
The Honeywell burner control system displays system faults by illuminating the red ALARM LED, and turning the
green POWER LED on and off in patterns. The patterns consist of one or more fast, and one or more slow,
flashes of the POWER LED. These patterns are sometimes referred to as “blink codes”. The following table
provides a description of the “blink codes” and their meanings.
