Genie intellicode h4000a will open but will not close

Out of the blue my Genie intellicode h4000a started to malfunction it will go up with both the remote in the wall switch but it will not go down
I disconnected the trolley and it still won't go down
Safety beams appear to be working both lights are on and when I brake the beam the red light flashes
   I tried increasing the downforce with no change
  The limit switches appear to be fine and I tried unplugging the down limit switch with no change
 The red light that flashes codes on the motor unit is not illuminated
I inspected both of the circuit boards and I don't see anything burnt on either
  I can open the door manually without any kinds of restrictions
I'm stuck

??? no one ?

It appears I have posted this in the wrong area if the moderator here could move it for me to the correct area would be greatly appreciated
