Looking for the circuit board electronic diagram for Honeywell 1011927 fan board

I am looking for the circuit board electronic diagram for Honeywell 1011927 furnace control fan board or aany similar board used in Heil/ICP furnaces (NTC6 and alike). Just in case, - I am not looking for the wiring diagram: I am trying to understand the board design for troubleshooting. Even an incomplete one would be helpful.

I wonder if those exist beyond the manufacturer's "inner yard".

They do not. The board design and schematics are purely proprietary and are never released to anyone outside the company.

Most of those boards get the same problems. Defective relays. Poor soldering of the relays, terminal strips and push-on wire connector tabs.
