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 Egan.
One side of your garage door has dropped lower than the other in Egan. A cable is hanging loose at the bottom corner of the door in Egan, LA. The door is tilted and jammed in the track in Egan. Do not operate the opener in Egan, LA. Do not try to manually move the door in either direction in Egan. Call Herlihy Garage Doors now for same-day cable repair throughout Egan, LA in Egan.
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 Egan, LA. When one cable fails, that load path is broken on the failed side in Egan. The door drops unevenly in Egan, LA. The surviving cable, drum, and bottom bracket on the intact side are now carrying approximately double their designed load in Egan. Hardware that was designed to share the door's weight with its counterpart is now bearing the full door weight alone in Egan, LA. Any of those overloaded components can fail without further warning in Egan. Operating the door in either direction makes this substantially worse in Egan, LA. 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 Egan. The force concentrates at the panel near the trolley bracket and bends or buckles the panel in Egan, LA. 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 Egan.
Herlihy Garage Doors identifies why the cable failed before replacing it in Egan, LA. A cable replaced without identifying the cause goes into the same conditions that destroyed the original in Egan. 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 Egan, LA. 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 Egan. We find the cause. We fix it right in Egan, LA.
The torsion spring stores energy as rotational tension in the spring coil in Egan, LA. 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 Egan. As the drums rotate, they wind the cables up from the drum groove, pulling the cables upward in Egan, LA. The cables attach at their lower ends to the bottom brackets at the lower corners of the door in Egan. 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 Egan, LA. The cable converts the spring's rotational energy into the linear upward force that lifts the door in Egan.
The cable attaches to the drum at the upper end and to the bottom bracket fitting at the lower end in Egan. 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 Egan, LA. Direction changes in a loaded cable create stress concentrations at the bending point in Egan. 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 Egan, LA.
The cable drum has a helical groove that guides the cable into a specific winding path as the drum rotates in Egan, LA. 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 Egan. 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 Egan, LA. This edge contact acts as a cutting mechanism that progressively cuts through the cable strands with each winding cycle in Egan.
Spring failure shock load — the cable snaps from the sudden tension surge when a spring breaks during door operation in Egan. 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 Egan, LA.
A cable that failed from a spring failure shock load requires spring replacement alongside cable replacement in Egan, LA. Without the spring replacement, the new cable is immediately exposed to the same shock load risk from the same broken spring in Egan. 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 Egan, LA. Each cause has a specific associated repair in Egan.
A correctly functioning two-cable system distributes the door weight evenly between both cables, both drums, and both bottom brackets in Egan, LA. Each side carries approximately half the door weight in Egan. When one cable fails, the remaining cable is carrying the full door weight in Egan, LA. For a 200-pound door, the intact cable has gone from carrying 100 pounds to 200 pounds in Egan. The cable, drum, and bracket on the intact side are all operating at twice their designed load in Egan, LA.
The intact cable carrying double its designed load is operating at a significantly higher fraction of its rated breaking strength in Egan. 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 Egan, LA. All three components are more likely to fail under the doubled load in Egan. A second failure in any of these components drops the door completely in Egan, LA.
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 Egan, LA. 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 Egan. 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 Egan, LA. Either form of force can release the door suddenly in Egan.
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 Egan. If the garage is partially open, lock any interior door connecting the garage to the home in Egan, LA. Call Herlihy Garage Doors now in Egan.
Garage door cables are specified by wire diameter, overall length, and construction type in Egan, LA. The correct wire diameter is determined by the door's weight and the cable's required working load limit in Egan. 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 Egan, LA. Herlihy selects replacement cables with the correct specification for the specific door's weight and configuration in Egan.
The cable drum has a helical groove machined into its surface that guides the cable into the correct winding path in Egan. 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 Egan, LA. 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 Egan. Herlihy confirms correct winding visually before the cable is loaded on every cable replacement in Egan, LA.
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 Egan, LA. Any height difference indicates unequal cable tension in Egan. The adjustment is made to match the height across the full door width in Egan, LA. Equal cable tension produces correct door height and correct load distribution between both sides in Egan.
The specific cause of the original cable failure is corrected before the new cable is installed and tensioned in Egan. 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 Egan, LA. The new cable goes into correct conditions rather than the conditions that failed the original in Egan.
Where a broken spring is the confirmed cause of the cable failure, Herlihy replaces both the cable and the spring in Egan. 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 Egan, LA.
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 Egan, LA. The current position determines the approach to safe manipulation of the door in Egan.
Specific cause of the cable failure identified through assessment in Egan. 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 Egan, LA.

All pricing confirmed upfront before work begins in Egan.
When a spring failure is the confirmed cause of the cable snap, both must be replaced in Egan. 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 Egan, LA. The door also won't operate correctly without the spring providing counterbalancing force in Egan. Herlihy identifies the relationship between spring condition and cable failure on every cable repair service in Egan, LA.
