Craftsman Garage Door Opener , opens on it's own
Craftsmen GD Opener 3/4 HP Model # 139.53990D Org. Owner and Installer.
Replace remote battery, worked fine. Then that night it opened by its self. And keeps doing it. Have unplugged it and tried that first. Do not see anything anywhere on how to trouble shoot it. Do not have much free time these days. Just would like to know what to troubleshoot next? erase codes?
Can't not leave the house without unplugging.

I can understand how difficult it is to have issues with your garage door opener. There may be something in the area that is causing the phantom opening of the garage door. Please make sure you know where all the remotes are and that you have taken the batteries out of any you are not using. Are there any remotes from an older discarded opener or old remotes in a drawer somewhere? I would suggest that you reprogram all your remotes to the motor unit and then see if you are having the same problem. If you are going away for a few days then I would suggest using the lock out feature on the wall control. However, this is usually caused by some radio frequency (rf) signal in the area. The rf confuses the logic board on the opener and can cause it to open intermittently. If you have rf interference the led on the logic board in the motor unit will usually blink. If the led is blinking slowly the rf signal is fairly weak. If the led is blinking rapidly, the rf signal is strong. The led will also flash an error code to indicate there is a fault in the garage door opener. I am sending you an image showing the error codes and probable causes. To search for something in your home that might be causing rf, begin by removing the battery from 1 remote. If there is no change put that battery back and remove the other one. Unplug one garage door opener, if there is no change plug that opener in and unplug the other one. If you have lost or replaced a remote in the past, search through drawers and the couch and chair cushions for the missing remote and remove the battery. These are the most common reasons for short range. To determine if the rf is coming from something in the garage or house, turn the house circuit breakers off one at a time. Try a remote after each breaker is turned off. If the range improves, the rf is coming from something on that circuit. If you don't find anything causing the short range, you can schedule service and get a Sears technician to check the openers. Sears technicians carry a meter that will find the source of the rf signal. If you can't find the source of the rf signal, you can replace the logic board in the motor unit and probably solve the problem. I hope this helps.
