I was wondering if anyone could give me some suggestions on this problem: My garage door opener will open but not close. It will only close if you hold your finger on the wall button the entire time. Otherwise it goes 2 inches down, then stops, backs up, and flashes the light bulbs on and off. The infrared electronic "eyes" installed at the base of the door can see each other ok, no obstructions, and both green led's are on. I have oiled all hinges with WD-40 as the manual suggests. I have tried increasing the downward force with the knob located on the unit but same result even it I max it out. I've also tried adjusting the downward limiter. The door is aluminum, two car garage type. This opener was new in August of 1995 and worked fine for 9 years, then suddenly this cropped up. I've seen other responses to this issue posted saying the door sensors are the culprit, but in my case both sensor lights are green. They stay green even if you put your foot in front, (should the color change if obstructed?) Here is the specs on it: Sears/Craftsman 1/2 HP Volts: 120 Amp: 5.0 Hz: 60 Model: 139.536415RT Chain Drive Thanks for any help. Jim

I am working on converting an old concrete block 2 car garage to a workshop. The ceiling joists sag and there is a crack down the back wall. I want to raise the ceiling from 8 feet to ten feet for reasonable amount of room to work, and stud the walls for insulation in the wall. I want to install a sheetrock ceiling and insulate the attic. I want to remove the garage doors and fill in the openings with a wall in both with a personnel door in one. The decision point would be whether or not a new one would be cheaper than modifying the old one. I hired a structural engineer to evaluate the structure and produce plans for its complying with code and enabling this modification. He says that it can be modified and the walls raised to ten feet. The plans are due next week. In deciding how to raise the roof, discussions were held about disassembling the roof structure and reassembling it atop the raised walls. Another suggestion was to lift the entire roof assembly and raise the walls, and replace the roof structure. I talked to a contractor about lifting the roof, raising the walls, and reseating the roof structure in its entirety. He said that it can be done, after the structure is reinforced as the engineer will specify. It will be an interesting project.
