You can plug the cord back in or have a professional service reset your fuses. To summarize, if you’re having trouble with your garage operator, it’s probably either unplugged or it may have blown a fuse. Problems with the circuit breaker should only be handled by a professional. Often, a more serious issue will prevent an operator from receiving power, such as a blown fuse or circuit breaker. People sometimes do such things and forget having done so. You might have absentmindedly unplugged the operator as you were exiting the garage through your internal door to the house. In the funniest of scenarios, the problem will simply be due to an unplugged power cord. Sometimes, a garage door won’t open or close for one reason only - the garage door operator has no power connection. Photo-eyes can become misaligned by fatigue, physical pressure, etc. If either light becomes misaligned with the other, the beam is rendered incapable of scanning the clearance.
On most garage door systems, the corresponding photo-eyes will consist of one red light and one green light. When the two sides interact, LED lights activate on both ends. With some garage doors that don’t close, the problem is due to a misalignment issue between the two photo-eyes. There is also the possibility that the circuitry of the photo-eye has been damaged or saturated with moisture or rain. In some cases where a garage door won’t close, the photo-eye will simply be dusty or dirty, and the dirt will be misinterpreted by the laser as a physical obstruction. Consequently, the slightest bit of anything - such as a pencil or a wad of paper - can trigger the photo-eye to halt the movement of the door. The purpose of the photo-eye is to ensure the door does not close down on objects, pets or people.Īs a safety mechanism, the photo-eye is programmed to respond instantly to any obstruction. If any type of object or body part is detected, the door either halts its closure or reverses in full. You can easily fix the problem by removing the obstruction or calling a service to have your photo-eye realigned properly.Įach time the door is prompted to close, the beam activates to scan the underlying clearance for obstructions. Upon activation, a pea-sized laser beam is sent from one end to the other.Ī miscellaneous object or dirt is most likely the culprit for your blocked photo-eye’s safety sensors. The photo-eye components consist of two pieces that align face-to-face across each side of the garage door, roughly four feet above the ground. The majority of garage doors manufactured since the early-1990s are equipped with this safety feature.
