Hello,
My garage door opener, Sears 1/2HP craftsman, quits working since yesterday. It just hums now for about half minute when the button (on wall or the on the remote control) is pressed. This happened when I started the opener as usual, it stopped at about half way, and returned to the closed position after pressed the button again. No more movement since then. Do I have to replace the opener?
The opener is about 15 years old.
Thanks for any suggestion or advice!
