Craftsman GDO - 3 flash indicator

bboehmJune 7, 2007


My 1/2 hp Craftsman is acting up by opening and closing on it's own. I have tried clearing the codes in the remotes but that has not fixed it. I have another identical GDO for my other door and it is perfectly fine. The yellow light on the back of the GDO is flashing 3 times. Anyone know what this code represents?



Thank you for reporting this comment. Undo

That code is a shorted wall control. I would remove it from the wall and then remove the 2 wires. (remember where they go for the new one) Should eliminate that problem.
