______________________________________________________________________ Does anyone have wire connections for thios board.

It is a Lennox G24M 4/5-120 furnace with a 33J6201 circuit board controller. I can get the fan to run in “cont” mode with heat and cool in the off position. But no fan when in the heat or cool position. Coming off the circuit board is the “cont”, “heat” and “Cool” connections for the fan motor. I swapped the “cont” and “cool” to verify the “Cool” winding was good. Fan did run. I think it is the relays on the circuit board. I would like to repair this circuit board but I don’t have a schematic. Can you help? Thanks, any help would be appreciated.

Its illegal to repair a part form a gas furnace therefore they only see new parts. Xenos. The best way to escape a problem is to solve it.
