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

The technician arrives with what's needed in Mundelein, IL.
The opener cannot lift a door that has lost its spring counterbalancing force in Mundelein, IL. Running the opener against the full door weight strains the motor, the drive gear, and the trolley mechanism in Mundelein. In the best case, the opener's force limit trips and the motor stops before damage occurs in Mundelein, 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 Mundelein. Do not run the opener with a broken spring in Mundelein, IL. And do not try to manually lift the door in Mundelein. A door without spring counterbalancing weighs its full 150 to 400 pounds with no mechanical assistance in Mundelein, IL. It will not hold a raised position without being held in Mundelein.
EZ Open's broken spring service covers a complete assessment of the door system including cable condition on both sides, drum condition, bottom bracket and roller condition, and track condition, identification of the correct replacement spring specification for the specific door, safe removal of the broken spring using correct winding bars and procedures, installation of the correctly specified replacement spring, winding to the correct turn count for the door height and drum size, cable inspection and replacement where the spring failure also caused cable damage, balance test with opener disconnected, and complete door operation verification before we leave in Mundelein.

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

The number of springs replaced is the primary driver in Mundelein. Whether cable replacement is also needed adds to the scope in Mundelein, IL. After-hours service carries an additional charge in Mundelein. High-cycle spring upgrades add to the cost but extend the service interval from approximately 7 years to 17 or more years in Mundelein, 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 Mundelein, IL.
