DCS Burner Flame Too High or Low
Burner Flame Too High or Low is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Blocked ports rather than a failing igniter
Hard water and its residue collect at burner ports over time, producing the uneven light that gets reported as an ignition fault.
A dirty or misaligned igniter
Debris or grease buildup prevents a clean spark, which is the single most common cause of ignition failure.
A faulty gas valve or regulator
Controls gas flow to the burner and can fail independently of the igniter.
