I installed a new Craftsman garage door opener by following the instruction booklet it came with, but after the installation was done and I plunged it in the outlet nothing will power up. Nothing lit up, or any movement. I made sure the outlet was working by plugging another device, and the other device worked but not the garage door opener. any suggestions?
There are two options here:
You're going to have to go through the whole set-up top to bottom. Check all your connections, make sure that batteries are in right, that any fuses are installed and work. Then call Sears.
