Garage Door Problems
My garage door slams shut or closes too fast.
The door accelerates on the way down, hits the floor harder than normal, or drops when the opener is disconnected. It may feel unusually heavy, refuse to stay halfway open, or pull the opener trolley down the rail.

What you may notice
The door accelerates on the way down, hits the floor harder than normal, or drops when the opener is disconnected. It may feel unusually heavy, refuse to stay halfway open, or pull the opener trolley down the rail.
What you're seeing
Why it happens
The spring system should counterbalance the door through its travel. A broken spring, incorrect spring tension, a failed cable, mismatched springs, or a mechanical bind can remove that support. An opener may slow or mask the symptom for a while, but it is not a substitute for a balanced door.
Springs counterbalance the door. A broken coil can remove that assistance and allow dangerous movement. Keep clear of a falling or uncontrolled door.

What you can check safely
- Do not stand in the opening. Observe the door only from the side and keep the travel path empty.
- Look for a spring gap, slack cable, shifted drum, or uneven bottom edge without touching the components.
- Do not perform a halfway balance test if the door already drops or cannot be controlled safely.
- Disconnect electrical power so the door cannot be activated accidentally while awaiting service.
Is it safe to keep using the door?
A dropping door is an immediate overhead-load hazard. Do not try to catch it, walk beneath it, or use the opener to hold it open. Do not adjust spring tension, cable drums, or bottom brackets yourself.
What the fix involves
The door is secured before the counterbalance system is tested. Springs are identified and matched to the door, cables and drums are inspected, and any binding track or roller condition is corrected. The repaired door must stay controlled by hand through its travel before the opener's limits and safety reversal are checked.
This is handled by our Springs, Cables & Tracks service. Check availability for your ZIP and exact service address before scheduling.
Cables transfer the spring system's lifting force to the door. Service checks cable seating, drums, the correct spring match and controlled movement as a system.

Quick answers
Is the opener supposed to keep the garage door from falling?
No. The spring system carries the door's weight. The opener guides a properly balanced door and should not be relied on as a support device.
What does a halfway balance test show?
On a safe, intact door, the test shows whether the counterbalance can hold the door near mid-travel. A door that already drops should not be tested by a homeowner because the known symptom is enough to stop use.
Could only one spring be weak rather than broken?
Yes. Incorrect or fatigued springs, a mismatched pair, or lost cable control can all produce poor balance even when no obvious gap is visible.

A door that falls is not an opener adjustment; it is a counterbalance problem until proven otherwise.
Safety and technical references
These references support the general safety guidance above. Your door and opener model instructions control for model-specific adjustments.
Door slams or falls: stop-use decision
A door that drops, slams or closes uncontrollably should not be operated again to measure the problem. Keep people clear and arrange assessment of the support and control system.
Do not catch it, lift it or pull the release
The useful record is the position it is in now and the uncontrolled movement already seen. Do not stand beneath it, put blocks under a hanging door or use a vehicle as support. A partly open door may need professional securing before permanent repair.
Do not assume changing a speed setting is the repair
Loss of controlled movement can involve counterbalance or other mechanical issues. An opener setting is not a substitute for assessing a door that has fallen or slammed. Describe visible spring separation, loose cable or skewed sections from a safe distance; do not touch the hardware to confirm it.
Separate securing from the lasting correction
Ask how the technician will secure the door and then identify the cause. The permanent proposal should explain which supporting or drive components need work and what operational checks will follow. A statement that the door “moves again” is not the same as explaining the fault or completing the applicable safety checks.
| Observation or choice | What it changes | What to record |
|---|---|---|
| Door is partly open | Professional securing may be needed first | Current position and access requirement |
| Door dropped/slammed | Do not repeat the movement | What was already observed |
| Visible spring/cable issue | Do not manipulate loaded components | Safe-distance description |
| Only a setting change proposed | Ask how mechanical causes were assessed | Finding and follow-up check scope |
