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

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