no spinkng englinch? someone might have the same code around your neighborhood, that happens sometimes, its happened to me, my opener would open someone elses and vice versa. reset your codes on the opener.

Recommend you change the code on the motor and remote chances that someone uses their remote to open their door but opens yours due to same code

If you change the codes and you still find it is happening it could be the Logic Board inside the garage door opener unit. It is not very common but I have seen it a few times. When the Logic Board goes bad they can start to do very strange things.

More then likely however, something is affecting it.

Check to see if your remote button isn't stuck. Sometimes mine would open after I closed it cuz of the button
