Openers from the 2000 build wave in Maple Valley were mostly 1/2 horsepower chain-drive, sized for standard steel sectional doors of that era. Two failure patterns turn up more than others: the drive gear inside the housing strips after enough winters of use, and the safety-reverse sensors at the base of the track drift out of alignment, which trips a code-required auto-reverse and stops the door from closing at all. Neither is a wiring problem, and neither gets fixed by resetting the remote.
The cold-moderate climate here also plays a role. Lubricant in an older chain-drive unit thickens in winter, and a motor already working near the end of its life stalls out on the first cold snap rather than the hundredth warm day. If your opener has been fine all summer and quit the first cold week, that's the pattern, not a coincidence.
