A Snapped Cable Can Leave Your Car Trapped Inside

When a high-tension cable snaps, your heavy garage door becomes dead weight, often hanging unevenly, jamming in the tracks, or refusing to open entirely. For homeowners in Big Bear, CA, a broken cable is not just an inconvenience; it is a significant safety hazard that traps vehicles and leaves the home vulnerable to the elements. Contact us to schedule a safety inspection and repair.

A snapped cable transfers all the door’s weight to the remaining cable and springs, creating an unstable situation that requires professional intervention. Attempting to force the door open or cut the remaining wire can lead to catastrophic hardware failure or personal injury:

• Technicians are available to secure the door and restore functionality.
• Service includes a comprehensive inspection of drums, springs, and tracks to prevent future failures.
• We utilize heavy-duty, aircraft-grade aircraft cables designed to withstand high-tension cycles.

Resolution for Jumped or Broken Cables

The garage door cable acts as the muscle of your entry system, working in unison with the torsion or extension springs to lift the heavy panels. When this component fails, the door is effectively paralyzed. Good Golly Garage Doors provides a streamlined repair service designed to minimize downtime and ensure the structural integrity of your garage system.

We address the two primary issues affecting cables: complete breakage and “thrown” or “jumped” cables. A broken cable is usually the result of years of wear, fraying, or rust, causing the wire strands to snap under tension. A jumped cable occurs when the wire slips off the drum, usually due to an obstruction in the track or a loss of spring tension. Both scenarios require a specific technical approach to fix correctly.

Our service visit focuses on more than just restringing a wire. We analyze the entire counterbalance system. If a cable broke due to a seized bearing or a rusted bottom bracket, replacing the cable alone will only result in another failure weeks later. We assess the condition of the drums, the alignment of the torsion tube, and the balance of the springs. By the time our truck leaves your driveway, the door will sit level, move smoothly, and seal tightly against the floor.

The Cable Replacement and Tensioning Process

Restoring a garage door with cable issues is a precise mechanical process. It involves handling components under extreme tension. We adhere to a strict safety protocol to ensure the repair is performed without risking property damage or injury:

• Securing the Door: The first step involves clamping the door in the closed position or securely blocking it if it is stuck open. This prevents the door from crashing down when tension is released from the remaining lifting components.
• Releasing Spring Tension: Before touching the cables, the tension on the torsion springs must be safely unwound. This is the most critical and dangerous part of the process, as the springs hold enough potential energy to cause severe injury. We use winding bars to control the release of this energy.
• Removing Damaged Hardware: We disconnect the loop from the bottom bracket. In many cases, specifically in older mountain homes, the bottom brackets may be rusted to the door. If necessary, we replace the bottom fixture to ensure the new cable has a secure anchor point.
• Installing High-Cycle Cables: We thread new, multi-strand galvanized steel cables up the height of the door and attach them to the drums. We ensure the cable length is perfectly matched to the door height and drum size. Mismatched lengths will cause the door to open unevenly.
• Setting the Drums and Winding: The cables must wind onto the drums cleanly without overlapping or tangling. We reset the drums on the torsion tube, ensuring equal tension on both sides. The springs are then rewound to the specific manufacturer-calculated turns based on the door’s weight.
• Leveling and Testing: Once tension is restored, we test the door’s balance. A properly fixed door should stay in place when lifted halfway manually. We adjust the tension to ensure the door sits level on the ground and lifts evenly without binding in the tracks.

Recognizing When to Repair vs. Replace

In the context of garage door cables, “repair” almost always means “replacement.” You cannot splice, tape, or clamp a frayed garage door cable. The structural integrity of the cable relies on the continuity of its steel strands. Once those strands begin to unravel, the cable is compromised and must be discarded.

However, the decision often extends to whether you should replace just the cables or overhaul the associated hardware:

• Fraying and Separation: If you see loose strands sticking out of the cable like a bad haircut, the cable needs replacement. This fraying often occurs near the bottom loop or where the cable passes over the drum. We replace both cables simultaneously, even if only one is frayed, to ensure equal stretch and tension.
• Kinks and Bends: A cable that has jumped the drum is often kinked. While it might look intact, a kink creates a weak point in the steel structure. Even if re-spooled, a kinked cable will likely cause the door to jerk during operation and will eventually snap at the bend. Replacement is the only reliable option.
• Rust and Corrosion: Surface rust might seem cosmetic, but it penetrates the inner core of the cable, making it brittle. In environments with moisture, rusty cables lose their flexibility and snap without warning. If the rust is flaking, the cable is at the end of its lifespan.
• Drum Damage: Sometimes the cable is fine, but the grooves in the cable drum are chipped or worn. A damaged drum will shred a new cable in days. In this instance, we replace the drums alongside the cables to ensure a smooth path for the lifting mechanism.

High-Altitude and Climate Considerations

Operating a garage door in Big Bear presents unique challenges that standard suburban environments do not face. The combination of freezing temperatures, heavy snowfall, and seasonal moisture creates a harsh environment for metal components. Standard cables often fail prematurely here if they are not maintained or selected correctly for the climate.

Moisture and Corrosion

Snowmelt and ice accumulation at the base of the garage door expose the bottom brackets and cable loops to constant moisture. This accelerates oxidation. We inspect the bottom corners of the door specifically for rot or rust that could cause the cable attachment point to fail, even if the cable itself is new. Good Golly Garage Doors recommends galvanized or stainless steel components for local homes to combat this accelerated corrosion.

Snow Load Impact

When snow piles up against the garage door, or when ice forms at the threshold, the motor and cables have to work harder to break the seal and lift the door. This extra strain can snap an aging cable that would otherwise operate fine in dry conditions. Ensuring your cables are rated for the heavy lifting required during winter months is essential for reliable access.

Why Professional Tensioning is Non-Negotiable

Cable repair is frequently cited as the most dangerous aspect of garage door maintenance. The cables themselves are under tension equivalent to the weight of the door, often several hundred pounds. This tension is held in check by the torsion springs and the drums. When a homeowner attempts to reattach a slipped cable without the proper tools to control the spring tension, the risk of the spring unwinding explosively or the door free-falling is high.

Our technicians carry the specific winding bars and vice grips required to lock the system down before any work begins. We do not rely on makeshift tools. Every repair involves a calculated release and re-application of torque. This ensures that the potential energy stored in the system is managed safely.

Furthermore, correct tensioning is vital for the longevity of your opener. If a cable is replaced but the tension is not balanced perfectly, the electric opener must compensate for the imbalance. This burns out the motor gears and logic boards, leading to expensive opener replacements down the road. We ensure the door is balanced so perfectly that the opener acts merely as a regulator, not the primary lifter.

Ensuring Long-Term System Health

A snapped cable is often a symptom of a larger issue, such as a door that is out of square, tracks that are misaligned, or bearings that have seized. Simply putting on a new wire without addressing the root cause will result in a repeat failure. Our approach involves a holistic view of the garage door system.

We verify that the track spacing is consistent from top to bottom. If the tracks are too wide, the door can fall out; if they are too narrow, the door binds, causing cable slack. We check the end bearing plates to ensure the torsion tube spins freely. If the shaft drags, the cables will lose tension momentarily during the cycle, increasing the risk of them jumping the drums.

We also examine the bottom fixtures. In many modern doors, the bottom fixture includes a safety device that prevents the door from falling if a cable breaks. We test these fixtures to ensure they are mobile and functional. If your door lacks these safety features, we can discuss upgrade options to enhance the safety of your home.
