Most calls we get from Cameron start the same way: the opener hums, the light comes on, and the door either doesn't move or moves a few inches and stops. Sometimes it's a grinding noise instead of silence. On a lot of houses out here, that symptom means something specific, because Cameron's housing stock is older than the service-area average - most of it went up around 1938, a decade ahead of the 1949 median we see across the rest of the territory. Doors from that era were built heavy: solid wood panels, no foam backing, hung without the weight-offsetting springs you'd find on a modern steel door. An opener that was sized for a lighter replacement door, or that's been straining against the original weight for years, burns out its motor, strips its gear, or snaps a drive cable well before it would on a newer door. If your opener is working hard and getting nowhere, the door itself - not just the unit on the ceiling - is usually part of the story.
