Craftsman GDO - 3 flash indicator

Hi

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?

Thanks!!

Bill
