Hey Garage Door Fans! I’m Chris Wilke with C&W; Canada Garage Doors and today we’re gonna talk about garage door opener sensitivity. Your garage door opener sensitivity is the safety system that allows the door to reverse. To test it is really simple. All you have to do is find a 2x4. Place it down in the center of the garage door’s path, and then hit the button. If the garage door reverses as you’ve just seen, then your garage door sensitivity is working properly. And when your door’s in trouble, you call C&W!
