I've got a friend with a furnace that keeps blowing control boards.
They go out about once a year. Anyone know where to get the schematic
for this board? This is the 4th one replaced in his Heil furnace. I
searched and all we find is people selling boards, no schematics.
Thanks,
Charlie Luke

SSR's are indeed junk... and perhaps just wiring in some real
relays will do the trick. If you still want the schematic, just get
a tech to trace out the circuit and measure the component
values... that what I do whenever I need a schematic and have
a sample board.

Best regards,

Jean
