Do not operate the opener. Do not try to manually move the door. Herlihy identifies why the cable failed before replacing it — correct specification, correct drum winding, tension equalized. Every cable repair guaranteed in Antioch.
One side of your garage door has dropped lower than the other in Antioch. A cable is hanging loose at the bottom corner of the door in Antioch, IL. The door is tilted and jammed in the track in Antioch. Do not operate the opener in Antioch, IL. Do not try to manually move the door in either direction in Antioch. Call Herlihy Garage Doors now for same-day cable repair throughout Antioch, IL in Antioch.
The garage door cable is the mechanical link that transfers the spring's stored energy from the cable drum to the bottom corner of the door on each side in Antioch, IL. When one cable fails, that load path is broken on the failed side in Antioch. The door drops unevenly in Antioch, IL. The surviving cable, drum, and bottom bracket on the intact side are now carrying approximately double their designed load in Antioch. Hardware that was designed to share the door's weight with its counterpart is now bearing the full door weight alone in Antioch, IL. Any of those overloaded components can fail without further warning in Antioch. Operating the door in either direction makes this substantially worse in Antioch, IL. Running the opener against the tilted door applies the opener's force to a door that's jammed in the track at an angle in Antioch. The force concentrates at the panel near the trolley bracket and bends or buckles the panel in Antioch, IL. Manually trying to move the door applies force to a system where one side has no cable support and the door can drop suddenly in Antioch.
Herlihy Garage Doors identifies why the cable failed before replacing it in Antioch, IL. A cable replaced without identifying the cause goes into the same conditions that destroyed the original in Antioch. The spring failure that sent a shock load through the cable. The worn drum groove that was cutting through the cable strands with each winding cycle. The incorrect drum winding from a previous repair that put the cable into contact with the drum flange in Antioch, IL. Herlihy identifies the specific cause, addresses it, replaces the cable with the correct specification for the specific door, winds correctly into the drum groove, equalizes tension between both sides, and verifies complete door operation before leaving in Antioch. We find the cause. We fix it right in Antioch, IL.
The torsion spring stores energy as rotational tension in the spring coil in Antioch, IL. When the door opens, the spring releases that rotational energy through the torsion shaft to the cable drums on each end of the shaft in Antioch. As the drums rotate, they wind the cables up from the drum groove, pulling the cables upward in Antioch, IL. The cables attach at their lower ends to the bottom brackets at the lower corners of the door in Antioch. As the cables are pulled upward by the rotating drums, they transmit the spring's stored energy as a lifting force at the bottom corners of the door in Antioch, IL. The cable converts the spring's rotational energy into the linear upward force that lifts the door in Antioch.
The cable attaches to the drum at the upper end and to the bottom bracket fitting at the lower end in Antioch. Both attachment points are where the cable changes direction — from linear tension to wrapping around the drum at the top, and from linear tension to a fixed point at the bottom fitting in Antioch, IL. Direction changes in a loaded cable create stress concentrations at the bending point in Antioch. This is why most cable failures occur at or near one of the two attachment points rather than in the middle of the cable run in Antioch, IL.
The cable drum has a helical groove that guides the cable into a specific winding path as the drum rotates in Antioch, IL. When the cable winds correctly in the groove, the cable-to-drum contact is distributed across the full cable diameter against the smooth groove surface in Antioch. When the cable miswinds — jumping out of the groove or stacking on top of a previous wrap — the cable contacts the sharp edge of the adjacent groove or wrap in Antioch, IL. This edge contact acts as a cutting mechanism that progressively cuts through the cable strands with each winding cycle in Antioch.
Spring failure shock load — the cable snaps from the sudden tension surge when a spring breaks during door operation in Antioch. Drum groove wear — the groove wears to a sharp edge that cuts through cable strands. Incorrect drum winding — cable contacts the drum flange or crosses over previous wraps from a previous repair error. Corrosion — moisture penetrates between wire strands and weakens the individual wires progressively. Physical damage — external contact bends or kinks the cable at a specific point in Antioch, IL.
A cable that failed from a spring failure shock load requires spring replacement alongside cable replacement in Antioch, IL. Without the spring replacement, the new cable is immediately exposed to the same shock load risk from the same broken spring in Antioch. A cable that failed from drum groove wear requires drum assessment and potentially drum replacement. A cable that failed from incorrect winding requires correct winding procedure on the replacement in Antioch, IL. Each cause has a specific associated repair in Antioch.
A correctly functioning two-cable system distributes the door weight evenly between both cables, both drums, and both bottom brackets in Antioch, IL. Each side carries approximately half the door weight in Antioch. When one cable fails, the remaining cable is carrying the full door weight in Antioch, IL. For a 200-pound door, the intact cable has gone from carrying 100 pounds to 200 pounds in Antioch. The cable, drum, and bracket on the intact side are all operating at twice their designed load in Antioch, IL.
The intact cable carrying double its designed load is operating at a significantly higher fraction of its rated breaking strength in Antioch. The drum on the intact side has the full cable tension rather than half. The bottom bracket on the intact side is bearing the full door weight at its attachment points in Antioch, IL. All three components are more likely to fail under the doubled load in Antioch. A second failure in any of these components drops the door completely in Antioch, IL.
Running the opener to close a door with a broken cable applies the opener's force to a door that's jammed at an angle in the track in Antioch, IL. The opener force pulls the door at the trolley attachment point while the track resists the tilted door's movement. The panel buckles at the trolley bracket location from the concentrated force in Antioch. Trying to manually force the door applies lateral force to a tilted door that's already being held by uneven cable tension on one side in Antioch, IL. Either form of force can release the door suddenly in Antioch.
Do not operate the opener. Do not attempt to manually move the door in either direction. Keep people and vehicles away from the door and door opening in Antioch. If the garage is partially open, lock any interior door connecting the garage to the home in Antioch, IL. Call Herlihy Garage Doors now in Antioch.
Garage door cables are specified by wire diameter, overall length, and construction type in Antioch, IL. The correct wire diameter is determined by the door's weight and the cable's required working load limit in Antioch. A cable undersized for the door weight operates at a higher fraction of its rated breaking strength on every cycle, accelerating fatigue and reducing service life in Antioch, IL. Herlihy selects replacement cables with the correct specification for the specific door's weight and configuration in Antioch.
The cable drum has a helical groove machined into its surface that guides the cable into the correct winding path in Antioch. The cable must be started in the correct position on the drum and wound in the correct direction for the specific side of the door being repaired in Antioch, IL. A cable started in the wrong position miswinds from the first cycle and immediately begins accumulating the cutting wear that produced the original failure in Antioch. Herlihy confirms correct winding visually before the cable is loaded on every cable replacement in Antioch, IL.
After both cables are installed and wound, Herlihy checks the door height across its full width by measuring from the floor to the bottom of the door at both ends in Antioch, IL. Any height difference indicates unequal cable tension in Antioch. The adjustment is made to match the height across the full door width in Antioch, IL. Equal cable tension produces correct door height and correct load distribution between both sides in Antioch.
The specific cause of the original cable failure is corrected before the new cable is installed and tensioned in Antioch. Spring replacement where spring failure caused the shock load. Drum assessment and replacement where groove wear produced cutting contact. Correct winding procedure where incorrect winding was the cause in Antioch, IL. The new cable goes into correct conditions rather than the conditions that failed the original in Antioch.
Where a broken spring is the confirmed cause of the cable failure, Herlihy replaces both the cable and the spring in Antioch. After the spring replacement, the balance test is performed with the opener disconnected to confirm the spring specification and winding are correct before the opener is reconnected in Antioch, IL.
Door position and angle assessed. Spring condition and tension state on both sides assessed. Both cables and both drums assessed for condition. Bottom bracket condition assessed in Antioch, IL. The current position determines the approach to safe manipulation of the door in Antioch.
Specific cause of the cable failure identified through assessment in Antioch. Spring condition assessed where spring failure may have caused the shock load. Drum groove condition assessed for wear that produced cutting contact. Cable winding path assessed for any mismatch from the designed path in Antioch, IL.

When a spring failure is the confirmed cause of the cable snap, both must be replaced in Antioch. Replacing only the cable while leaving the broken spring means the new cable immediately faces the same shock load risk from the same broken spring in Antioch, IL. The door also won't operate correctly without the spring providing counterbalancing force in Antioch. Herlihy identifies the relationship between spring condition and cable failure on every cable repair service in Antioch, IL.
