If the door is hanging crooked, with one side noticeably lower than the other, that's a cable off the drum or snapped - not a sensor problem, no matter what the opener light is doing. A frayed cable looks like a handful of thin wires splaying out near the bottom bracket or up at the drum, and it's worth a call before it fully lets go, since a half-frayed cable under load can snap suddenly and drop the door hard. A door that's merely noisy or slow isn't a cable symptom on its own - that's more often the spring or the rollers. Given the area's median household income near $98,000 and a housing stock that's held up well since the late 1990s, most of what we see here is wear-driven, not storm or impact damage, so there's rarely a bent track involved.
