Craftsman Garage Door Opener

I recently had a Craftsman garage door opener installed. Twice now I have came home from work and the door was open. The first time I had notice the clocks blinking in the house so I didn't know if the power going out could have opened it when it came back on. Today I came home and it was open again...clocks weren't blinking this time. Does anyone out there know what could be opening the door?

    i have the same problem - and thanks for the code idea. i checked my paperwork, and found that the door supposedly changes with each use of the opener - that should negate the "neighbor" issue, but i have no other ideas about why it's happening. i read the "cold weather" comments - wonder if that applies - it started in jan. after 3 months of working fine.

I posted the following answer to a similar question posed by 'dodgeya' the other day.
I'm not sure how to direct you to that thread, so am re-copying my suggestion here...

>> Do you have the option to change the electronic codes on your garage door opener system? My father-in-law had the same problem a number of years ago. He had not reset the code (equivalent to the combination on a lock) from the equivalent of 0-0-0 (which his unit shipped with). Turned out that a neighbor (or neighbour - in Canada) had the same /similar unit and when the neighbor opened 'his' door, my father-in-law's door would also open. You don't have to see the person drive by - it can be the neighbors behind you as well. You may find a solution by determining if you can change the original electronic code to a different one of your own choosing.
Hope this helps.

What does the purple button light flashing on 1/2 horsepower craftsman garage door opener


I think the adjustment mode is on.

For example, that's from Craftsman manual:

""
Setting the Force
The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door.
1. Locate the purple button on the left panel of the motor unit (Figure 1).
2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly.
3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position.

""

Actually, you should just read carefully your garage door opener unit's manual.

Craftsman 1/2hp garage opener Homelink must be under unit to work


Have you tired reprogramming the remotes to the opener?

The opener receiver board may have failed, which happens. You can order a new one from Sears or other places on the Internet, and they are fairly easy to replace.

Once replaced, you will need to program the receiver to you remotes again.
