Garage Door Won't Open or Close? Run These Five Checks First

A garage door that worked yesterday and won’t move today almost always has one of five problems. Run these checks in order - they take about five minutes, cost nothing, and by the end you’ll either have a working door or know exactly what to tell us on the phone.

1. Check the lock before anything else

Older Shelby County doors often have a manual slide lock on the inside of the door, and it gets bumped more often than anyone admits. Some openers also have a “vacation lock” on the wall console - a switch or button that deadens the remotes on purpose. If the wall button works but the remotes don’t, that lock is your answer.

2. Look at the safety sensors

The two little eyes near the floor on either side of the opening must see each other for the door to close. Look for a steady light on both. A blinking light means they’re blocked or knocked out of line - a broom handle, a trash can, six inches of drifted snow, or a sensor bracket bumped by a bike tire. Clear the beam, gently square the brackets until both lights go steady, and try again. This fixes more “broken” doors than any other single check.

3. Find the red cord

If the opener hums but nothing moves - or you had a power blip overnight - the trolley may be disconnected. The red emergency-release cord hangs from the rail above the door. With the door fully closed, pull it firmly toward the door, then run the opener: on most units the trolley clicks back in on the next pass. If your power is out entirely, that same cord is how you open the door by hand.

4. Try lifting the door by hand

Pull the red cord (door closed), then lift the door manually. A healthy door lifts smoothly with one hand and will hold still at waist height. If it feels like lifting an engine block, stop - your spring is broken, and neither you nor the opener can safely move that door. Look up at the shaft above the door: a broken torsion spring shows an obvious gap in the coil.

5. Listen to what it does when you press the button

• Nothing at all, no lights: power problem - check the outlet the opener is plugged into and your breaker panel.
• Click but no motor: likely a logic board or capacitor - a repairable opener fault.
• Motor runs, door doesn’t move: stripped drive gear or disconnected trolley (see check 3).
• Starts, then reverses: safety sensors (check 2) or a force setting that needs adjustment.
• Loud bang happened earlier, now dead weight: that was your spring.

What to do with what you found

Checks 1-3 you can fix yourself, and you should - no service call needed. Check 4’s broken spring and check 5’s opener faults are our territory: springs are under real tension and openers are cheap to fix but easy to misdiagnose. Either way, when you call, tell us which check failed - that one sentence usually means we arrive with the right part on the truck.
