increase or decrease as necessary.
Ignition Electrodes
Check electrodes for carbon buildup and clean if necessary.

cracks in porcelain; if found replace.
Air Switch

the switch is making (closing). Also check the adjustment of
the air switch setting. If both above do not work, check the
range of the air switch and measure the burner fan pressure at
the air pressure switch sensing port to make sure the air switch

assembly piping, which closes under pressure and opens
under vacuum.
