    Craftsman ½ HP not opening or closing; light flashes 10 times

    Post  haybarn564 on Mon Nov 13, 2017 11:34 pm

    This morning, the garage door opened with no problem. When I went to close it, it did not respond. I was already driving away so I called my wife, who said she could not get it to close. Eventually she had to close it manually. Upon returning home, when pressing the switch, sometimes the unit immediately flashes 10 times and then does nothing. Sometimes it starts to try and engage, then reverses and flashes 10 times. The manual says nothing about anything past 6 flashes, so I don't really know what this means. I've tried pulling trolley back up to re-engage it, but it doesn't click back in when I pull it all the way back up. 
    Any suggestions as to what is going on here? Nothing is blocking the sensors on either side.

    Attaching a few pictures.

    Appreciate any help you can give. I don't know a whole lot when it comes to garage doors so any tips will be welcome!

    What brand is it?
    How old is the unit?
    Is the left side of the trolley bent? It's hard to tell from the pictures.

    You may want to take the cover off of the motor unit & look inside at the drive gear. Most operators have a plastic drive gear that can wear out or break over time. If you take the cover off & see white shavings inside then you know that the gear probably needs replaced.
