Why does my garage door only open a few inches then stop?
A straight answer from a Florida state-certified contractor — then what you can check yourself and when to call. Free estimate: (954) 620-7812.
The most common cause is that the door is too heavy for the opener to lift, usually because a spring has broken or a cable has slipped. The opener strains, raises the door a few inches, then stops or reverses to protect itself. A door that is binding in its tracks, or a lock that is still engaged, can produce the same symptom.
The nuance is that this is not really an opener problem in most cases. Replacing the opener will not help if the springs are carrying none of the door's weight. Work out whether the door is balanced before you spend money on the motor.
Why it happens
A garage door is counterbalanced by springs, either torsion springs on a bar above the door or extension springs along the tracks. Those springs do most of the lifting, and the opener only guides the door. When a spring breaks, the full weight lands on the opener. A motor sized for a balanced door cannot move that load, so it gives up after a few inches.
Other causes work the same way by adding resistance. A cable can come off its drum, a roller can jump out of the track, or a bent track section can pinch the door. Corroded hinges and rollers can also make the door drag. In Florida, humidity and salt air near the coast speed up rust on springs, cables and hardware, so worn parts can fail without much warning.
Less often the opener itself is the cause. Force or travel-limit settings can drift, or a lock-mode setting on the wall console can interrupt the cycle. Those causes are usually fixed with a settings adjustment, not a part replacement.
What you can check yourself
Look for a broken spring or loose cables
With the door closed, look at the spring above the door. A visible gap in a torsion spring, or a spring or cable hanging loose, points to a failure. Look only. Do not touch the spring, its bracket or the cable ends.
Test the door by hand
Pull the red release cord to disconnect the opener, then try lifting the door a little. A balanced door feels fairly light and stays put at about waist height. If it is very heavy, or slams down when you let go, stop and leave it alone.
Check for a lock or obstruction
Make sure any slide lock on the door is released and the wall console is not in lock mode. Look along the bottom edge and tracks for debris, a stuck item or a bent track.
Inspect the safety sensors
Wipe both photo-eye lenses and confirm their lights are steady. Sensors mostly affect closing, but misaligned ones can cause odd behavior on some openers.
When to call a pro
Call a pro if you see a broken spring, a slipped cable, a door off its track, or a door that is heavy when disconnected. Garage door springs hold a lot of stored tension, and the usual injuries come from people trying to loosen or wind them without the right tools.

Permits are the other consideration. A permit is typically required to replace a garage door and its track and jamb anchorage. Opener-only or hardware repairs, such as a spring, cable, roller or opener swap, often are not permitted. If the door is old or damaged enough that replacement makes sense, expect the permit, in-progress and final inspections, and close-out path. Inspectors usually focus on how the door is anchored to the jamb and structure. In Miami-Dade and Broward, the High-Velocity Hurricane Zone requires a Miami-Dade Notice of Acceptance (NOA) for the product. Elsewhere in Florida, the door needs Florida Product Approval. Confirm the details with your city or county building department. We pull permits under our Florida Certified Building Contractor license (CBC1265305) when the work needs one, schedule the inspections, and close the permit out. An open or unpermitted replacement can come up at sale, refinance or insurance renewal.
What a pro will do
- Diagnose the balance and the causeWe check the springs, cables, drums, rollers, hinges and tracks, then the opener, so you pay to fix the actual fault and not just the symptom.
- Repair spring, cable, roller or track problemsSprings and cables are replaced as matched, correctly sized parts. Rollers, hinges and bent track sections are repaired or replaced, and the door is rebalanced.
- Repair or replace the openerIf the opener is worn or its settings are off, we adjust or replace it and set the force and travel limits properly.
- Replace with a wind-rated door when neededWhere the door is beyond repair, we install a wind-rated or impact-rated door per its product approval, with the reinforcement and anchorage it calls for, permitted and inspected.
Related questions
- Can I just replace the opener if the door will not lift?
- Usually not. If a spring or cable has failed, a new opener faces the same heavy door and will struggle the same way. Fix the balance first, then judge the opener.
- Is it safe to keep trying the opener?
- Repeated attempts can wear out the opener's motor and gears. It is better to stop, disconnect the opener with the release cord, and have the door checked.
- Does fixing a spring need a permit?
- Spring, cable, roller and opener repairs often do not. Replacing the door and its anchorage typically does. Your local building department can confirm what applies to your address.
- How much will the repair cost?
- It depends on which part failed, the door's size and weight, the condition of the tracks and hardware, and whether the door needs replacing. We give a free quote after looking at the door.
- Why does my older door matter in hurricane season?
- A garage door is often the largest opening in a house, so one that is not rated for the area's wind pressures can be a weak point in a storm. If yours needs replacing anyway, a wind-rated door is worth discussing.
