Having some lights going on or off is merely an annoyance but today, my garage door suddenly started closing on me while I was already inside the car backing out. Apparently, I never noticed the garage door coming down because it was just starting to close and I was backed up far enough for it to be out of my field of vision. Timing was just perfect as the back of my car roof contacted with the bottom part of the garage door enough to push a couple of the bottom garage door wheels out of the track (this is a roll-up door). I was able to stop in time to cause any further damage. Fortunately, the damage was minimal (I hope) as I was able to push the tracks back into alignment although my garage door is now slightly bowed.
I am using the Linear GD00Z-4 garage door opener but there was no usual warning beeps. It was as if someone physically push the garage door button or remote. I checked the logs and there was no mention of an app causing the door to close. I think my WAF just dropped down to zero!
