For a year my system
worked flawlessly. Then the other day Door #1 stopped working. I
tried to reprogram it, and it turned out the sensor battery died on Door #1.
So I replaced both sensor batteries.
I tried to reprogram everything, which may have been a mistake. Now, when I push the program button on Door #1 during the program process, Door #2 opens halfway, stops, closes, and Door #1 opens and closes. Then it says it is programmed. When I use the app to open the door, it is opening both doors at the same time.
I am not even sure why Door #2 is being picked up during the programming process, because I am not even pushing the program button on Door #9 at the time. Any idea why? This worked flawlessly for 1 year.
