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

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