How do I know if my photo eye is actually broken? Hold your hand in front of the door as it closes. If it doesn't stop or reverse, the photo eye isn't working. Both sensors must have steady LED lights. If either light is off or flickering, the system needs repair.
Can I cover my photo eyes to disable the auto-reverse? No. Covering them is dangerous and illegal. The auto-reverse exists to prevent serious injury. Disabling it voids your opener warranty and creates liability if someone gets hurt.
How often do photo eyes need replacement? Most sensors last 5 to 8 years with normal use. Coastal salt air on Merritt Island accelerates corrosion, so expect replacement sooner than inland homeowners. Annual cleaning extends their life significantly.
Will a new garage door opener fix my photo eye problem? If only the sensors are broken, replacing the entire opener wastes money. Sensors cost far less. However, if your opener is 15 years old, replacement might be smarter long-term than constant repairs. We can advise on when replacement makes sense).
What if I don't have a photo eye system? Openers older than 1993 may lack photo eyes. This is a serious safety gap, especially with children or pets around. Installing a retrofit photo eye kit costs $200 to $350 and should be your priority.
