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

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