Here is exactly what happened in Knollwood, IL. The torsion spring above your door had been accumulating metal fatigue cycle by cycle through every open and close in Knollwood. 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 Knollwood, IL. The rotational energy that was counterbalancing your door's weight transferred instantly through the shaft and disappeared in Knollwood. The door lost its counterbalancing force in that same instant in Knollwood, IL. If the door was moving when the spring broke, the side near the broken spring dropped faster than the other side in Knollwood. 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 Knollwood, IL. 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 Knollwood.

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

The torsion spring is wound to a specific rotational tension when installed in Knollwood, IL. That tension is what stores the energy used to lift the door in Knollwood. The winding process compresses the spring wire's grain structure at the boundaries between coils in Knollwood, IL. Over thousands of cycles, microscopic cracks develop at the highest stress points in the wire structure, typically near the winding cone in Knollwood. When a crack propagates through the full cross-section of the wire, the spring fractures in Knollwood, IL. The stored rotational tension releases instantly through the fracture point in Knollwood. 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 Knollwood, IL. The bang is the sound of that energy releasing in Knollwood.
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 Knollwood. 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 Knollwood, IL. Now the spring's counterbalancing force is gone in Knollwood. 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 Knollwood, IL. If the door is in any raised position, the cables are carrying the full door weight without spring assistance in Knollwood. The cables are under approximately twice the tension they were designed to carry in that case in Knollwood, IL.
This is the symptom most homeowners notice first in Knollwood, IL. You press the opener button. The opener motor runs. The trolley travels along the rail. But the door doesn't move in Knollwood. This is the expected behavior when the spring has broken in Knollwood, IL. The opener is designed to provide a small net force against a door that's already counterbalanced by the spring in Knollwood. 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 Knollwood, IL. It can't in Knollwood. The opener is not broken. The spring is in Knollwood, IL.
Look at the bottom corners of the door in Knollwood, IL. 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 Knollwood. The door will be visibly lower on the side with the broken cable in Knollwood, IL. If both cables appear taut and the door is at an even height despite the broken spring, only the spring has failed in Knollwood. EZ Open assesses both cables as a standard part of every broken spring repair service in Knollwood, IL.
A door that's in the fully closed position with a broken spring appears completely normal from the outside in Knollwood. It's sitting on the floor, it looks like a closed garage door, and it may seem safe to attempt to open in Knollwood, IL. It isn't in Knollwood. The moment anyone tries to open it, with the opener or manually, the full door weight must be lifted without spring assistance in Knollwood, IL. The opener can't do it in Knollwood. 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 Knollwood, IL.
A standard single-car steel garage door panel assembly weighs 130 to 200 pounds depending on the gauge, insulation, and window configuration in Knollwood, IL. A standard double-car door weighs 200 to 400 pounds in Knollwood. 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 Knollwood, IL. Without the spring, the full panel assembly weight must be lifted by the opener or by manual effort in Knollwood. Neither is designed for this and neither can do it safely in Knollwood, IL.
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 Knollwood. The spring tension exactly balances the door weight and the door stays put in Knollwood, IL. With the spring broken, there's no counterbalancing force in Knollwood. The door's weight pulls it downward the moment you release it in Knollwood, IL. If you raise it manually and let go, it will drop in Knollwood. A 200-pound door dropping from the halfway open position generates significant force in Knollwood, IL.
The opener motor is rated for a specific torque output that's designed to move a counterbalanced door in Knollwood, IL. Running the opener against the full door weight without spring assistance puts the motor in an overload condition in Knollwood. The motor draws more current than its rated load in Knollwood, IL. It runs hotter than its designed operating temperature in Knollwood. 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 Knollwood, IL. In some cases the force limit trips and stops the motor before damage occurs in Knollwood. In others, the drive gear strips and the opener requires repair alongside the spring replacement in Knollwood, IL.
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 Knollwood. It's not in Knollwood, IL. The cables are under significantly elevated tension carrying the full door weight in Knollwood. 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 Knollwood, IL. If a cable releases or a bottom bracket fails under the elevated load, the door drops completely in Knollwood.
EZ Open's technician arrives with springs covering the common residential configurations in Knollwood, IL. On arrival, the door height, estimated weight, and cable drum size are confirmed to select the correct spring for the specific installation in Knollwood.
Before any repair begins, EZ Open performs a complete system assessment in Knollwood. Both cables in Knollwood, IL. Both drums in Knollwood. Both bottom brackets in Knollwood, IL. All rollers in Knollwood. Track condition in Knollwood, IL. And the surviving spring on a two-spring system in Knollwood. The assessment identifies any secondary damage the spring failure produced in Knollwood, IL.
The broken spring pieces are removed from the shaft using correct procedures in Knollwood, IL. 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 Knollwood. Full unwinding is confirmed before the spring is released from the shaft in Knollwood, IL.
The replacement spring is installed on the shaft with the winding cone positioned correctly in Knollwood, IL. The set screws are started but not fully tightened until after winding is complete in Knollwood.
The spring is wound to the calculated turn count for the specific door height and cable drum size using professional winding bars in Knollwood. The set screws are tightened to the correct specification in Knollwood, IL. The cables are reattached to the drums with correct tension in Knollwood. The opener is disconnected and the door is manually lifted to the halfway position in Knollwood, IL. The door is released and observed in Knollwood. Correct balance confirmed in Knollwood, IL. Opener reconnected and full cycle test completed in Knollwood.
Both springs were installed at the same time and have completed the same number of cycles in Knollwood, IL. Metal fatigue is a function of the number of cycles and the stress per cycle in Knollwood. Both springs have experienced identical cycle counts under identical stress conditions in Knollwood, IL. The spring that broke reached its individual fatigue threshold first due to microscopic variations in wire structure in Knollwood. The other spring has reached essentially the same point in its fatigue progression in Knollwood, IL.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Knollwood, IL. 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 Knollwood. The total of two separate repairs is consistently higher than the cost of replacing both during the original visit in Knollwood, IL.
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 Knollwood, IL. In this specific situation, replacing only the broken spring with a matching specification is the correct choice in Knollwood. EZ Open assesses the surviving spring's age and specification and advises accordingly in Knollwood, IL.
EZ Open recommends replacing both springs when both are at the same fatigue progression in Knollwood, IL. The recommendation comes with the specific reasoning so the homeowner can make the decision with complete information in Knollwood. EZ Open never withholds the reasoning or pressures the outcome in Knollwood, IL.

While EZ Open is already on site for the broken spring replacement, upgrading to high-cycle springs rated for 25,000 or more cycles is the most cost-effective time to make this upgrade in Knollwood, IL.
