I installed a GoControl GD00Z-4 Garage Door Opener a couple of months ago and the install seemed flawless. The opener worked great. I don’t use it often, and today I tested it expecting it to work fine. However, the door started to open and immediately stopped…it might have moved once cm.
My initial thought was that something was blocking the safety sensors or the door might be locked, etc. But when I manually pushed the button on the wall, the door went down, then went up all the way until it was fully opened. I closed the door with the button and tried the GoControl again. Again, the same issue.
I checked the battery on the open/close sensor and it was 100%. (I use @RBoy’s DTH that reports battery %) I even took the sensor off, reseated the battery, reseated the sensor and still the same behavior… starts to open and abruptly stops when the motion of the door starts.
I then manually opened the door one more time with the button. Once it was open, I tried closing it using the GoControl. It worked. I then tried opening it with the GoControl…it worked. At this point I thought whatever glitch I had was smoothed out. But an hour or so later I tried to open with the GoControl, and it stopped immediately once the open motion started. After playing with the wall button to make the door open/close a few times, it started working again. It seems like it never has trouble closing, but is frequently having trouble opening, until I “prime” it.
Any ideas what might be going on? The GoControl is connected to the opener directly, not wired to the wall button or anything odd.
