Craftsman Garage Door Opener

slarsSeptember 12, 2010

I installed a new 1/2 hp Craftsman garage door opener. I completed the installation at night and the opener worked fine. The next morning the door opened but didn't close. After trying all the obvious adjustments I'm guessing the problem is direct sunlight falling on the door sensors. However even when the sun is not directly shining against the sensors the opener won't work. The opener works at night just not during any part of the day time. Any recommendations will be appreciated.

If the door starts to close and then reverses and the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor is lit and not blinking ever so slightly. Try tweaking them a bit to see if the problem improves. If not call Sears and let them figure it out. There is a warranty.

Thank you very much for the idea. The sensor lights always glowed, never flickered or went out, so I assumed they were aligned correctly. Your recommendation to tweak them worked. I moved the sending unit ever so slightly and the door opener is working fine. The sensor never did flicker or go out the entire time I re-aligned it.
Thanks again,
