When the tech installed my central air, all I had was a 3 conductor cable going to my thermostat. So I cannot use the fan feature on the thermostat,
So I installed a 4 conductor cable replacing the 3 conductor cable.
What I do not know is where to connect the green wire on the board WHITE ROGERS 50A50-241 to make that just the fan run without the compressor coming on.
Thanks
Jeff

The "G" will connect to the green wire at the thermostat and the furnace.

Thanks for your help.
What I notice is that the Y (yellow wire) joins to a green wire that goes to the G terminal.
Thanks
Again

What I notice is that the Y-yellow wire is joined with two other wires namely a green and red and the green goes to the G terminal

The yellow should not be connected to the green wire, they did this to bring on the fan with the a/c.
