Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

Garage door opens by itself

We have a 19 year old home with a Stanley 1/2 hp garage door opener. The problem is 2 fold. When it gets cold out...below 30, the door will close and then open by itself. We also have it open by itself during the day when we are not home or will hear it go up in the middle of the night. I have followed all the adjustment guidelines but nothing seems to help. We have a second garage door, same opener, and have never had a problem with that one.

How to reset garage door opener pad without old acess number


A Stanley garage door keypad is wall-mounted, battery-operated device that allows you to open your home's garage door electronically without having to manually lift the door or use a pull chain. The keypad uses a four-digit access code that you program after the keypad is initially installed. You can change the code, disable the keypad manually by entering a invalid code and reset the keypad if the device is not working properly. After you reset your Stanley garage door keypad, the device is ready to accept a new access code.

I have two Sears 1/2 hp garage door openers. Cold weather problem


Very strange they both have the same exact problem. I would suspect something with the brackets is changing. When you are having this problem and the light on the receiver unit is not lit, tweak them a bit and see if it comes on. The odds of the logic board in both openers having the same thermal problem is just too high.
