I just replaced an old Chamberlain garage door opener with a new Chamberlain Model HD200D, 1/2 HP. The remotes that I had with the old one will not work with this new opener, all three of which just worked a few days ago with the old opener. The openers are model 953CBH. I have tried pushing the learn button then pushing the opener button and nothing happens. Do I need to get the 953D model remotes or will these work?
Thanks in advance!!
