Know what the door is telling you.

Practical explanations from more than a decade of hands-on garage door work.

Broken spring warning signs

Why a door may only lift a few inches and why repeatedly using the opener can cause more damage.

What can make a door hang crooked—and why replacement is not always necessary.

How door balance, sensors, drive parts, and age affect the recommendation.

Straight answers to the questions homeowners ask most often.

Start with the symptom

You do not need to name the failed part. These patterns help you describe the problem clearly and know when to stop operating the door.

A broken spring is a common cause. Stop forcing the opener, especially if the door feels unusually heavy by hand.

A cable, roller, track, or spring problem may no longer be controlling one side. Keep clear and do not pull the release.

The trolley may be disconnected, the door may be locked, or a drive component may have failed. Test nothing under a hanging door.

Safe homeowner checks

Visual information is helpful. High-tension repairs are not a safe DIY project.

01
Look from a safe distance
Check whether the door is level, whether a spring has a visible gap, and whether a cable is hanging loose.
02
Stop repeated operation
Each additional attempt can bend panels, strip opener parts, or pull the door farther out of the tracks.
03
Share the symptom
Call or text the city, what the door did, and safe photos. Leave springs, cables, bottom brackets, and unstable sections untouched.

Use these guides to understand the symptoms—not as instructions for high-tension repairs.
