I am just now in front of my computer to be able to reply. Thank you for the interest in helping to resolve this issue.
I am no where near my home (and the controller) so don’t know how productive it would be to talk today. It will have to be later in the week.
I can tell you this: I am getting a flashing red light on the middle light. After I unsuccessfully try to blink up,it flashes 3 short lights then one long light. I unplug and replug the controller in to reset the unit, and get the same result.
When I am trying to blink up, the garage door is closed and the lights are off, my cell phone (Android) is set on the highest brightness, the phone is in direct contact with the controller. I’ve tried it at various angles to see if that made a difference. Nothing has worked.
Perhaps that gives you some insight on what is going wrong.
