Sears Garage Door Opener automatically opens
I just purchased and installed a new Sears Craftsman 1/2 HP Garage Door Opener with rolling code tranmsmitters less than a week ago. Since it has been installed, we have found the door open on several occassions. No one in the household pushed any buttons to open the door. Since we have been finding it open we have been double checking that it is for sure closed when we close, but still have found it open later on.
Any ideas on why it is opening automatically? If it has a rolling code transmitter I thought this prevents neighbors from having the same code, but could this still be happen
