WARNING
Possible C ause
• Burner venturi, caps or ignition
ports clogged.
• Poor ground on burner cap.
• Low gas pressure.
• W eak spark m odule.
• No 120 VAC to unit.
• M icro switch contacts not closing.
• Failed wiring or poor connection at
burner cap electrode and electrode
socket.
• Failed spark m odule.
• Electrode dirty, burner cap dirty.
• Cracked or broken electrode,
electrode wire or electrode socket.
• Cracked ignitor or a pinched ignitor
lead wire.
• Poor connection of ground or lack
of continuity to ground of ignitor.
• Cracked or broken ignitor extension
lead.
• Reversed polarity. W hen polarity is
correct, no voltage is present at
neutral to ground and no voltage to
spark m odule with switch in "O FF"
position.
• Failed valve switch.
• Switch has been pulled up and off
of fixed position on valve so that it is
not turned to "O FF" position w ith
