The Fenwal 35-63J103-013 Ignition Control Board Intermittent Pilot Ignition Control is a microprocessor based ignition control suitable for replacing many existing intermittent pilot ignition controls from various manufacturers. Parts4heating stocks this control to replace the Johnson Ignition Control.
This ignition control is a direct form, fit and functional replacement for the discontinued Johnson G670AW-1, G670AW-1C, G67AG-3, G67AG-10 G67BG-3, G770LGA-1, G770LGA-2, G770LGC-1, G770LGC-1, G770LGC-2, G770LGC-3, G770LGC-4, G770LGC-10, G770LHA-1, G770LHA-2 and G770LHC-1 controls.
Fenwal is not just a universal type aftermarket control; it was designed to be a drop-in replacement. Design began with the physical size of the box, continued with wire placement (which is the exact match to the Johnson control) and focused on a number of details, right down to the wire terminal numbers on the side.
