Here is exactly what happened in Foster City, CA. The torsion spring above your door had been accumulating metal fatigue cycle by cycle through every open and close in Foster City. When the fatigue reached the threshold the wire couldn't sustain, the spring failed and released its stored rotational tension in a fraction of a second in Foster City, CA. The rotational energy that was counterbalancing your door's weight transferred instantly through the shaft and disappeared in Foster City. The door lost its counterbalancing force in that same instant in Foster City, CA. If the door was moving when the spring broke, the side near the broken spring dropped faster than the other side in Foster City. If the door was stationary, it's now significantly heavier than the opener can lift and the cables are the only thing keeping it from dropping if it's in a raised position in Foster City, CA. If the spring broke while the door was in motion, the sudden drop may have sent a shock load through the cable that snapped it too in Foster City.

The opener cannot lift a door that has lost its spring counterbalancing force in Foster City, CA. Running the opener against the full door weight strains the motor, the drive gear, and the trolley mechanism in Foster City. In the best case, the opener's force limit trips and the motor stops before damage occurs in Foster City, CA. In the worst case, the motor continues to run against the overload and the drive gear strips or the motor windings burn out in Foster City. Do not run the opener with a broken spring in Foster City, CA. And do not try to manually lift the door in Foster City. A door without spring counterbalancing weighs its full 150 to 400 pounds with no mechanical assistance in Foster City, CA. It will not hold a raised position without being held in Foster City.

The torsion spring is wound to a specific rotational tension when installed in Foster City, CA. That tension is what stores the energy used to lift the door in Foster City. The winding process compresses the spring wire's grain structure at the boundaries between coils in Foster City, CA. Over thousands of cycles, microscopic cracks develop at the highest stress points in the wire structure, typically near the winding cone in Foster City. When a crack propagates through the full cross-section of the wire, the spring fractures in Foster City, CA. The stored rotational tension releases instantly through the fracture point in Foster City. The sudden release of several hundred foot-pounds of rotational tension in a fraction of a second produces the sharp, loud bang you heard in Foster City, CA. The bang is the sound of that energy releasing in Foster City.
Before the spring broke, the door's weight was being counterbalanced by the spring's stored tension transmitted through the shaft and drums to the cables in Foster City. The cables were in tension carrying the door weight from the bottom brackets, but that tension was exactly balanced by the spring's counterbalancing force in Foster City, CA. Now the spring's counterbalancing force is gone in Foster City. If the door is in the closed position, its full weight is resting on the floor through the bottom panel and the door is stable but immovable in Foster City, CA. If the door is in any raised position, the cables are carrying the full door weight without spring assistance in Foster City. The cables are under approximately twice the tension they were designed to carry in that case in Foster City, CA.
This is the symptom most homeowners notice first in Foster City, CA. You press the opener button. The opener motor runs. The trolley travels along the rail. But the door doesn't move in Foster City. This is the expected behavior when the spring has broken in Foster City, CA. The opener is designed to provide a small net force against a door that's already counterbalanced by the spring in Foster City. With the spring broken, the opener is trying to lift the full door weight with only 10 to 20 pounds of net lifting force in Foster City, CA. It can't in Foster City. The opener is not broken. The spring is in Foster City, CA.
Look at the bottom corners of the door in Foster City, CA. If one cable is hanging loose at the bottom corner rather than running taut from the bottom bracket up toward the drum, the cable on that side also failed in Foster City. The door will be visibly lower on the side with the broken cable in Foster City, CA. If both cables appear taut and the door is at an even height despite the broken spring, only the spring has failed in Foster City. EZ Open assesses both cables as a standard part of every broken spring repair service in Foster City, CA.
A door that's in the fully closed position with a broken spring appears completely normal from the outside in Foster City. It's sitting on the floor, it looks like a closed garage door, and it may seem safe to attempt to open in Foster City, CA. It isn't in Foster City. The moment anyone tries to open it, with the opener or manually, the full door weight must be lifted without spring assistance in Foster City, CA. The opener can't do it in Foster City. A person doing it manually is lifting 150 to 400 pounds with no mechanical assistance and the door will not hold a raised position in Foster City, CA.
A standard single-car steel garage door panel assembly weighs 130 to 200 pounds depending on the gauge, insulation, and window configuration in Foster City, CA. A standard double-car door weighs 200 to 400 pounds in Foster City. These weights are what the spring counterbalancing system reduces to the 10 to 20 pounds of net force the opener is designed to move in Foster City, CA. Without the spring, the full panel assembly weight must be lifted by the opener or by manual effort in Foster City. Neither is designed for this and neither can do it safely in Foster City, CA.
When the door is raised manually with the opener disconnected and the spring is intact, the spring's counterbalancing force holds the door at whatever height you leave it in Foster City. The spring tension exactly balances the door weight and the door stays put in Foster City, CA. With the spring broken, there's no counterbalancing force in Foster City. The door's weight pulls it downward the moment you release it in Foster City, CA. If you raise it manually and let go, it will drop in Foster City. A 200-pound door dropping from the halfway open position generates significant force in Foster City, CA.
The opener motor is rated for a specific torque output that's designed to move a counterbalanced door in Foster City, CA. Running the opener against the full door weight without spring assistance puts the motor in an overload condition in Foster City. The motor draws more current than its rated load in Foster City, CA. It runs hotter than its designed operating temperature in Foster City. The drive gear, typically a plastic or nylon gear that meshes with a metal worm gear, is under significantly more torque than its design rating in Foster City, CA. In some cases the force limit trips and stops the motor before damage occurs in Foster City. In others, the drive gear strips and the opener requires repair alongside the spring replacement in Foster City, CA.
In situations where the spring broke while the door was in a raised position, the door may appear to be holding itself up normally in Foster City. It's not in Foster City, CA. The cables are under significantly elevated tension carrying the full door weight in Foster City. The cable, drum, and bottom bracket on both sides are under loads they were designed to share with the spring tension rather than bear alone in Foster City, CA. If a cable releases or a bottom bracket fails under the elevated load, the door drops completely in Foster City.
EZ Open's technician arrives with springs covering the common residential configurations in Foster City, CA. On arrival, the door height, estimated weight, and cable drum size are confirmed to select the correct spring for the specific installation in Foster City.
Before any repair begins, EZ Open performs a complete system assessment in Foster City. Both cables in Foster City, CA. Both drums in Foster City. Both bottom brackets in Foster City, CA. All rollers in Foster City. Track condition in Foster City, CA. And the surviving spring on a two-spring system in Foster City. The assessment identifies any secondary damage the spring failure produced in Foster City, CA.
The broken spring pieces are removed from the shaft using correct procedures in Foster City, CA. On two-spring systems where both springs are being replaced, the surviving spring is unwound using professional winding bars following the correct unwinding sequence in Foster City. Full unwinding is confirmed before the spring is released from the shaft in Foster City, CA.
The replacement spring is installed on the shaft with the winding cone positioned correctly in Foster City, CA. The set screws are started but not fully tightened until after winding is complete in Foster City.
The spring is wound to the calculated turn count for the specific door height and cable drum size using professional winding bars in Foster City. The set screws are tightened to the correct specification in Foster City, CA. The cables are reattached to the drums with correct tension in Foster City. The opener is disconnected and the door is manually lifted to the halfway position in Foster City, CA. The door is released and observed in Foster City. Correct balance confirmed in Foster City, CA. Opener reconnected and full cycle test completed in Foster City.
Both springs were installed at the same time and have completed the same number of cycles in Foster City, CA. Metal fatigue is a function of the number of cycles and the stress per cycle in Foster City. Both springs have experienced identical cycle counts under identical stress conditions in Foster City, CA. The spring that broke reached its individual fatigue threshold first due to microscopic variations in wire structure in Foster City. The other spring has reached essentially the same point in its fatigue progression in Foster City, CA.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Foster City, CA. When the second spring breaks, and at the same fatigue progression it will, the cost is a second call-out charge, a second spring, and potentially a second after-hours charge in Foster City. The total of two separate repairs is consistently higher than the cost of replacing both during the original visit in Foster City, CA.
If the surviving spring was replaced recently, within the last year or two, it has significantly fewer fatigue cycles than the broken spring and is not at the same risk of imminent failure in Foster City, CA. In this specific situation, replacing only the broken spring with a matching specification is the correct choice in Foster City. EZ Open assesses the surviving spring's age and specification and advises accordingly in Foster City, CA.
EZ Open recommends replacing both springs when both are at the same fatigue progression in Foster City, CA. The recommendation comes with the specific reasoning so the homeowner can make the decision with complete information in Foster City.
