Garage Door Won't Open? Here's What's Actually Wrong.
You're probably reading this on your phone, standing in the garage, coffee going cold, car trapped behind a door that quit. Take a breath. Nine times out of ten it's one of the checks below, and half of them cost nothing but two minutes. Mo here. Let's find yours.
“If the garage made one loud BANG recently and now the opener strains and lifts nothing, stop reading. That's a snapped torsion spring, and it is not a homeowner job. Skip straight to the phone.”. Mo
Direct answer
The most common reasons a garage door won't open, in order.
A garage door that won't open usually has one of nine problems: a locked-out wall console, a dead remote battery, no power at the outlet, confused safety sensors, a pulled release cord, a stripped opener gear, a cooked capacitor or logic board, a snapped torsion spring, or a broken lift cable. The first five are two-minute homeowner checks. The last four are service calls, and two of those are dangerous. Here's how to tell which one you've got.
Start at 01. Stop when it opens.
The list is sorted by most likely and least effort. Work down it in order. If you reach 07 and the door still won't move, put the tools down and pick up the phone.
Check the lock button.
Every wall console has a lock button, sometimes labeled, sometimes not. Kids press it. Elbows press it. When it's on, remotes and keypads go dead but the wall button still works. If the wall button opens the door and the clicker doesn't, press and hold the lock button a few seconds, then try the remote again. That's the whole repair. No charge. Don't tell anybody.
Swap the remote battery.
Sounds insulting. Fixes thousands of doors a year. A coin-cell battery costs a couple bucks in any checkout lane. If the remote's range got short before it died completely, that was your warning. Swap it, stand inside the garage, test. Fresh battery and still nothing while the wall button works? The remote may need reprogramming. The steps are in the owner's manual, or call and we'll walk you through it free.
Make sure the opener has power.
Look up. The opener's light should glow or blink when you hit the button. Nothing at all? Check the ceiling outlet. Garage outlets in Georgia homes often ride a GFCI circuit, and summer thunderstorms trip them constantly. Hit reset on the GFCI (it may be across the garage or in a bathroom), then check the breaker panel. Storm season fills my schedule with dead openers that were one tripped breaker.
Look at the safety sensors.
The two little eyes near the floor mostly cause doors that won't CLOSE, but a chewed or loose sensor wire can confuse an opener into doing nothing at all. Each sensor should show a steady light. Blinking or dark means blocked, knocked out of line, or a wire is off. Clear the cobwebs, gently aim them at each other, and eyeball the thin wires stapled up the wall. Weed eaters are the usual suspects.
Check the red release cord.
See the red handle hanging off the opener rail? If somebody pulled it, usually during a power outage, the trolley is disengaged and the motor runs happily while the door sits still. With the door DOWN, pull the cord toward the door to re-engage, then run the opener until it clicks back in. If the door is stuck OPEN, do not touch that cord. The door can free-fall. That one's a phone call.
Listen for a hum or a grind.
Press the button and listen. A hum with no movement, or grinding like a coffee mill, usually means the opener's drive gear stripped. Common on older chain units, and the fix is a gear kit or, on a tired motor, a new opener. Georgia summers also cook capacitors, which is the single click and then silence. Either way it's a bench diagnosis. That's our opener repair department.
Look at the springs above the door.
Torsion springs live on the shaft above the door. A healthy spring is one continuous coil. A snapped one shows a clean two-inch gap, and you'll usually remember the bang, like a firecracker in the garage. With a broken spring the opener is trying to lift the door's full weight, 150 pounds or more, and it won't. Stop here. Spring work is the repair that puts homeowners in the ER. It's our job, not yours.
Check the cables.
Lift cables run down both sides of the door. If one is frayed like a paintbrush or hanging slack, the door is a cycle away from jamming crooked in the tracks, and a crooked door under spring tension is genuinely dangerous. Same rule as springs: hands off, phone on. The cable itself is a cheap part. What you're paying for is the tech who handles the tension safely.
Do the lift test.
Need the car and the opener is dead? With the door fully DOWN, pull the red cord and lift the door by hand. A healthy door lifts smooth with one hand and stays put at waist height. If it lifts like a refrigerator or slams back down, the springs are shot and the door is unsafe to run. Park in the driveway tonight and call in the morning. Before 11am usually gets you same-day.
The 2am panic tax.
Type “garage door won't open” at midnight and the top ads know exactly how stuck you feel. Some outfits price by desperation: a fee to show up, then a “special” spring, then a hard pitch on a whole new door because yours is “obsolete.” I've re-quoted those jobs the next morning at a fraction of the number. Same door. Same parts.
