Sometimes it’s obvious when you need a repair: maybe your remote is as unresponsive as a teenager at 7 AM or there's an unnerving grinding noise every time the door moves. But other times, issues are more subtle—like when the door reverses for no apparent reason. We’ve seen all sorts of culprits behind these shenanigans—from misaligned safety sensors to haunted circuit boards (just kidding on that last one).Finding what's wrong often requires a bit more than just poking around; sometimes we get calls from folks who've been trying to channel their inner handyman only to find themselves knee-deep in springs and wires.
