Track Misalignment or Damage
Track misalignment or damage is another common reason a manual garage door may fail to open from the outside. The tracks guide the door’s movement, and any bends, dents, or obstructions can hinder its operation. Over time, tracks can become misaligned due to accidental hits, settling foundations, or wear and tear. If the tracks are damaged, the rollers may come off, causing the door to jam or stick. Additionally, dirt, debris, or rust on the tracks can prevent smooth movement. Inspecting the tracks for any visible damage or misalignment is crucial. Cleaning the tracks and ensuring proper alignment can often resolve the issue. If the damage is severe, replacing the tracks may be necessary to restore proper functionality.
Jammed or Damaged Handle
A jammed or damaged handle can prevent a manual garage door from opening properly. If the handle is stiff or stuck, it may not engage the release mechanism effectively. This issue often occurs due to dirt, rust, or debris accumulating inside the handle’s mechanism. In some cases, the handle might be bent or broken, making it difficult to grip or turn. To address this, inspect the handle for any visible damage or obstructions. Cleaning the mechanism with a lubricant, such as WD40, can help if the handle is simply stiff. If the handle is broken, replacing it with a new one is the best solution. Ensuring the handle functions smoothly is essential for easy and reliable door operation.
Troubleshooting Steps
Begin by checking the garage door lock to ensure it’s not engaged. Inspect the manual release mechanism for any damage or obstructions.
