QUESTION: I installed a garage door opener two years ago. It works during summer, but sometimes will not close other times. It comes down one foot from the floor and then goes back up. What it causing this?ANSWER: It sounds as though your garage door opener safety switch may be improperly adjusted. It is designed to reverse a closing garage door in case an object is blocking it.During summer’s heat, it moves freely enough; during cooler weather, something is binding or a stiffer lubricant is causing just enough resistance to make it think something is under the door.Have a professional serviceman check the safety switch adjustment. Don’t try to adjust it yourself.
