Well, it finally happened to me. Testing a new overhead door/opener.
1st tested the photo sensors…no problems.
I don’t use an object other than the pressure of my hand to test the resistance auto-reverse.
Stuck my hand under and applied a little pressure…door kept going down. I let go and it was coming down and as I was approaching the button I noticed the door stop…but the opener kept going…before I could hit the button…CRUNCH!!:eek:
Homeowner came back and I immediately explained what happened. He said he installed it and said he had problems with it tracking right from the start…I could see he was not thrilled, but he said “well, it is what it is” nothing you could have done. He took responsibility for it…whew! Anyway, that was a first for me and it totally sucked seeing it happen.
