The sensors on your garage door play a very important role. They are responsible for detecting any kind of objects that could be in the way of the up and down movement of garage doors. This could be anything from a basketball, to a car, or even a pet or a child. Your garage door safety sensors essentially operate as the “eyes” of your garage and are one of the most important safety features. The Consumer Product Safety Commission passed a law that set safety standards for all residential garage doors way back in 1991. This legislation stated that all garage doors must be equipped with an inherent reversing mechanism that will reverse the door if something is in the way. This mechanism usually relies on electric eyes to achieve this. Even though garage door sensors have been mandatory features for almost 30 years, many homeowners often forget they are even there. When do garage door sensors need to be replaced, and when is it just a simple fix?
