Garage Door opening and closing at random


Its a craftsman 1/2. From the looks of it (came with the house) its about 4-5 years old.

First the programmed key in my car to open and close the door stopped working. After it finally opened, I hit the learn button to reprogram the car and it shut the door. So I went back to the wired keypad and opened it.

It shut it immediately when it got to the top. This went on for a while until I gave up because I had to leave. All the while, this green light which I'm assuming is for the learned remote was flashing wildly.

I came back tonight and even though I had set it on manual, it had apparently tried to open and close again because it had reengaged the motor and tried to pull the door up again. (I had the door locked because I had left it on manual open)

Tonight, I tried the actual remote and it worked on and off but was still opening and closing at random.

Finally I shut it and unplugged the unit.

Anyone ever heard of this before? I haven't touched a thing on it ever.

Do you have the safety eyes at the edge of the garage door, to sense for objects in the path of the door?

Yes and I checked them but would they also force the door to shut automatically?

Tex,
Short of an exorcism, here's a few things to try.
Disconnect the wired keypad just to get it out of the system for now. Everything nowadays is wireless, which basicly just adds another remote to the system.
Next, go to the opener head, push the learn code button and hold it down until the green light next to it goes out. You have now cleared all the codes out of the memory.
Disconnect the door from the opener by pulling the cord and run the door up and down by hand to assure it rolls smoothly and without requiring undue force from you.
Hook the door back up and try using the wall button to run the door up and down. If it works that way, next, get your remotes and hit the learn code button and code up each one. Check the operation with the remotes.
One thing, with the sears operators, don't run the door up and down more than 7 or 8 times in a row without giving it a break. It's pretty easy to burn up the starting capicitors on these. If you see a big puff of smoke come out, the capicitor is history.
The other thing you may want to do is turn up the opening and closing force adjustments on the opener head before checking the operation. If everything gets to working properly, then you can back them off to their proper adjustment. Let us know what happens.

This is a problem with the opener, not an outside influence. Did you look on the web at the manufacturer's F&Q's? The flashing lights are the clue:

I agree that the lights are probably a clue, but disagree that you can rule out an outside influence. Depending on the exact door, many will still turn on if in manual mode ( since on many doors manual is simply a disconnect from the drive mechanism) So if the door is in "manual" and you hit the button, motor still functions, just doesn't lift or lower the door. It could be that the button in the car is malfuntioning ( sticking) and constantly sending a signal to the door. The flashing lights could simply be an indicator that the open is recieving a signal. Park the car out of range, see if anything changes then. it could also be that when you were reprogramming car remote, you didn't finish the process...
