Winters here get cold enough, under the severe cold-climate classification that covers this whole service area, to stiffen grease in rollers and tracks and make marginal springs fail on the first hard freeze rather than gradually. That's true whether the door was built in 1989 or 2001, but it shows up differently depending on the hardware. In Spanish Springs's newer stock, the more common failure is a nylon roller gone brittle in the cold against a track that was never lubricated after install, or a photo-eye sensor whose bracket has crept out of alignment from seasonal ground movement. We're six miles out from our Sparks base to get here, so we're not going to pretend we're parked around the corner - but the drive doesn't change what we find once we're looking at the door.
