New door wont go down. Blinks 10 times. I have adjusted the sensors and both have lights.
I'll take a guess it thinks something is in the way, maybe a box on the floor would clear but it sees it on the electric eye. Something like that. Sometimes it's a staple fastening wire as it is run to the opener. Possible shorting out the two wires that doesn't allow the motor to start to close door. If maybe remote, it may not be coded to the opener, get manual or internet to find out procedure out to do that.
