I recently moved into a house with a chamberlain garage door opener. It worked well the first few weeks and now has stopped. The lights are all on and when I push the wall switch or the remote opener, it makes a noise like it wants to open but won’t move. All the tracks look fine and in place, the manual release handle seems to be in place (not disconnected from the trolly). It looks like a pretty new unit….series 2100 1/3HP.
Any suggestions?
