The recent flooding in the Chicago area (especially near our Park Ridge, IL office) has damaged many garage door safety eyes (aka ir sensors). These sensors are mounted on both sides of the garage door opening and within 6 inches of the floor. All openers manufactured after 01/2003 are required to have these sensors per UL325. They are designed to reduce entrapment risks by sending an infrared light beam from one side of the garage opening to the other. If the sensors are not working properly then the garage door opener will NOT close from a remote control.
Does the residential garage door opener have a reversing mechanism and is it in working order?
SAFETY TIP: A faulty or improperly adjusted reversing mechanism on your garage door opener could cause damage to your car or even injure a child or pet that inadvertently gets caught in the way of the closing door. All garage door openers manufactured and installed after 1981 are required to have a reversing mechanism. Many of these can be installed by the do-it-yourselfer.
