2 RED Spark fail

What the control is telling you

Two red flashes after the ON button is pressed: the control tried to spark but did not get a pilot.

Applies to: 300DVBLN/PSC7, 400DVBLN/PSC7, 500DVBLN/PSC7 (Signature Command)

Likely causes

• Sparker lead or pilot connections loose
• Spark is jumping to the wrong place (under the pilot) instead of into the gas stream
• Sparker not positioned in the path of the pilot gas
• Control board picking up interference from nearby metal / poor grounding

Test and repair steps

1. Check the pilot connections at the control board
2. Look at the spark if it happens under the pilot, re-install or replace the pilot assembly
3. If the spark is not in the gas path, adjust the sparker position or replace the pilot assembly
4. Check grounding; re-install or move the control board, or replace it if the problem stays
