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 lift cable has slipped off the drum or a roller bearing has seized and popped out. Operating the door in this state can completely drop the heavy panels.
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 Sunnyvale and the cities around it.
A garage door that quits half way up is being held there by one of three things, and from the floor they all look alike. The counterbalance over the opening may still have hold of it. The machine on the rail may still have hold of it. Or the door may have fouled on something — a roller run out of its track, a bottom corner caught on the jamb — in which case what is holding it is an accident rather than a support, and nothing about an accident says it will go on holding.
That third case is why a stopped door gets worked from the side and never from beneath, and why the counterbalance is settled before anyone touches what the door has caught on. It is also the one thing worth acting on while a van is on its way: whatever the door has caught on stays where it is until somebody is there to hold the door. Pulling the obstruction clear can put a stopped door back in motion at a moment nobody has picked.
The build record is precise about one thing here and openly stuck on another. Half of Sunnyvale's housing was finished by 1975, a median that carries a margin of 1 year. Ask the same table which decade built the city and it declines: 11,532 units went up in the 1950s, 11,217 in the 1970s and 11,032 in the 1960s. The two furthest apart of those three, 11,532 and 11,032, are 500 units apart against 986 of published error. Between them the three rows hold 33,781 of the 61,808 housing units counted inside the city limits.
None of which narrows down what is hanging over any one opening, so it gets taken as found, garage by garage. And a door that has sat in the same position for two days has not shown that it is stable. It has only not been asked to move since.
