Why won't my garage door close?

Common reasons include: misaligned safety sensors, obstructions in the door path, broken springs, stripped gears in the opener, or issues with the close limit settings. Check the safety sensors first - they should both have steady lights.

Should I repair or replace my garage door?

Consider replacing if: the door is over 15-20 years old, has significant rust or structural damage, panels are severely damaged, or you want to upgrade to an insulated door. Many issues like springs, cables, sensors, and openers are cost-effective to repair.

What do the blinking lights on my garage door opener mean?

Blinking lights indicate error codes. For LiftMaster/Chamberlain: 1 blink = sensor wire issue, 2 blinks = sensor wire short, 3 blinks = door control wire issue, 4 blinks = sensor misalignment, 5 blinks = motor issue. Use our error code lookup tool for specific diagnosis.

How do I calculate what torsion spring I need?

To calculate the correct torsion spring, you need: door height, door width, door weight, track type, and number of springs. The formula involves IPPT (Inch-Pounds Per Turn) = d^4 × E / (10.8 × D × Na). Use our spring calculator for accurate results.

Can I replace a garage door spring myself?

Torsion spring replacement is dangerous and recommended only for trained professionals due to the extreme tension (over 200 lbs of force). Extension springs are safer for DIY but still require proper safety precautions and tools.

Garage Door Stuck or Off Track

Some Experience Needed30 minutes - 2 hours

A stuck or off-track garage door is usually caused by broken cables, obstructions in the track, worn rollers, or track damage. If the door is completely off track or cables are broken, call a professional. Minor track issues and obstructions can often be fixed at home.

Common Symptoms

Door stops halfway up or down
Door is crooked or tilted
Rollers have come out of the track
Door moves jerkily or binds
Visible gap between roller and track

Possible Causes

•Broken or frayed cable
•Track obstruction or damage
•Worn or broken rollers
•Bent track
•Broken spring causing imbalance
•Loose track brackets
•Opener force settings too low

How to Fix It

Disconnect the opener

Pull the emergency release cord to disconnect the door from the opener. This prevents the opener from trying to move a stuck door.

Inspect for obstructions

Look along the entire track for debris, bent areas, or objects blocking the path. Remove any obstructions.

Check the cables

Look for broken, frayed, or loose cables on each side of the door. If cables are broken, call a professional.

Do not attempt to repair or replace cables yourself. They are under extreme tension.

Examine the rollers

Check if any rollers have come out of the track or are cracked/broken. For minor derailment, you may be able to guide the roller back into the track.

Check track alignment

Use a level to check that vertical tracks are plumb and horizontal sections are level. Loosen brackets to adjust if needed.

Test manual operation

With the opener disconnected, try moving the door by hand. It should move smoothly. If it's heavy or binds, there may be a spring issue.

When to Call a Professional

•Door is completely off track
•Cables are broken or frayed
•Door is extremely heavy (broken spring)
•Track is severely bent or damaged
•You can't safely access the problem area

Frequently Asked Questions

Can I fix an off-track garage door myself?

Minor derailments where a roller has slipped out can sometimes be fixed by guiding the roller back into the track. However, if multiple rollers are out or cables are involved, call a professional. The door is extremely heavy and dangerous.

Why does my garage door keep going off track?

Recurring derailment usually indicates worn rollers, loose track brackets, or a track that's bent or out of alignment. Have a professional inspect and fix the underlying cause.

How much does it cost to fix an off-track garage door?

Costs vary depending on the extent of the damage. If new rollers or track sections are needed, or if springs are involved, the repair will be more expensive. Get quotes from local professionals.
