You don’t need to be Sherlock Holmes to spot when something's amiss with your garage door opener. It might start with small annoyances: maybe the remote needs an extra push or two, or perhaps there are some mysterious noises during operation—like it’s trying to communicate in Morse code. But let those signs go unchecked, and soon enough, you'll find yourself with a full-blown mechanical mutiny on your hands.Symptoms can range from sporadic functioning to complete unresponsiveness—and believe me, neither makes for a good morning surprise. The last thing anyone wants is their day hijacked by hardware hiccups.
