Identify what your door is doing before you call. If it is one of these, do not keep operating it.
Your torsion spring has snapped under intense torsional load. Forcing the opener to lift the door without spring assistance will burn out the motor or snap the drive belt.
A stripped internal nylon drive gear or a blown starting capacitor. We carry complete carriage gear rebuild kits in our trucks to repair your system immediately.
Don't let a snapped spring, snapped cable, ripped weather seal, or a defective remote keep you locked inside. Our expert teams carry fully stocked dispatch trucks. We regularly perform comprehensive garage door maintenance (inspection, lubrication, adjustment, and component testing) to keep your system safe. We serve Cupertino and the cities around it.
Cupertino's census record runs to 22,341 housing units and puts 64.2% of them in place before 1980, which is a firm enough answer about the town as a whole. Sorting that stock into eras is where the same table stops cooperating. The 1950s and the 1980s come out level, and the newer end of the record does the same thing, with 1,597 units dated to the 2000s and 1,247 to the 2010s, 350 apart with 355 of margin on the difference. Rank Cupertino's housing by size and the ranking sorts less than it appears to.
That is not a fault in the survey. It counted dwellings, one per address, and a dwelling is the wrong unit for the thing hanging in your garage. A garage door is held by a counterbalance specified against weight — the door is heavy, the spring or springs carry that weight so the opener does not have to, and the cables and drums hand it along to the shaft the springs are wound on. Weight is what the whole assembly is set against, and nothing the census counted is denominated in it.
The machine on the ceiling is calibrated the same way, and to the same door. Travel limits and force settings are set against how that particular door actually moves on the day somebody sets them, which makes them a record of one door's behavior rather than a specification anyone could look up. Change what is hanging in the opening, or change how well it is balanced, and those settings are describing something that is no longer there.
So the census answered the question about those two decades by declining to answer it, and declining was right, because the gap between them is inside its own error. We start a Cupertino call in the same position and would rather say so than guess. The year a house was finished is a fact about the house, and it has never been a shortcut to what is over the opening or to what is carrying it.
