Garage Door Lights that are attached to your garage door opener are not just ordinary lights. Yes, they burn out and have to be replaced, but they also serve a function of letting you know when your garage door is encountering a difficulty. If your garage door won't close, but your light flashes, that usually means that something is blocking your garage door's path. This is an important safety feature. For help with trouble shooting your door's behavior, just call us at 864-513-1436. Our phone consultations are totally free.
