Control board has thermal issue. Bad solder joint that contracts when cold could be the culprit. Take out board and carefully resolder every ****** connection on board.

Your limits are damaged. Will need to replace the limit switch.

Adam, I don't know how old the GDoor opener is but if it has served you for long time, it's asking for retirement. These days brand new units are cheap and will give you many years of trouble free use.

That is a two-flash code. It means either the wires to the safety sensors have a short in them, or one or both sensors are wired incorrectly at the motor unit. What you describe sounds like there may be a break in the wire, and the door causes the tracks to move just enough to open that break in the sensors. There could be a staple through the wires causing a short (I've done that when using a staple gun), and that could be your problem. Check your sensor wires from the motor down to the sensors themselves, and be sure they have a little bit of wiggle room. If you find a staple or something has cut the wires and caused a short, you can separate the wires a bit, and wrap each side separately with electrical tape.
