It’s 7 AM, you’re running late, and your garage door won’t budge. I get these calls every day, and in about half the cases, the problem is something the homeowner can resolve in five minutes. In the other half, you need a professional — but there are still things you should and shouldn’t do while you wait.
Here’s the troubleshooting sequence I walk customers through on the phone, in the exact order you should try it.
Step 1: Check the Obvious Stuff First
Before you assume something is broken, rule out the simple causes:
Is the opener plugged in? I know it sounds basic, but I’ve driven to homes where the cord got knocked loose. Check the outlet on the ceiling where the opener plugs in.
Did someone engage the lock? Many garage doors have a manual slide lock on the inside. If the lock bar is engaged (slid into the track), the opener can’t move the door. Disengage it and try again.
Are the photo-eye sensors blocked? Look at the two small sensors at the bottom of the door tracks, about 6 inches off the floor. If something is blocking the beam (a box, a broom, a cobweb), the door won’t close. One sensor will have a steady light, the other should too — if it’s blinking, the beam is obstructed. See our safety sensor troubleshooting guide for more details.
Try a different remote or the wall button. If one remote doesn’t work but the wall button does, it’s a remote battery issue, not a door issue. Swap the battery (usually a CR2032 coin cell).
Step 2: Listen to What the Opener Does
When you press the button, pay attention:
Nothing happens at all: No lights, no sound, no click. This is likely a power issue. Check the outlet, check your circuit breaker panel for a tripped breaker, and check the GFCI outlets in the garage (press the reset button).
You hear a click or hum but the door doesn’t move: The motor is getting power but can’t move the door. This could be a stripped gear inside the opener, a broken spring, or the door is locked/obstructed.
The motor runs but the door doesn’t move: The trolley may have disconnected from the carriage. Look at the rail running from the opener to the door — there’s a trolley that connects to an arm on the door. If the emergency release (red cord) was pulled, the trolley is disengaged. Push the trolley forward toward the door until it clicks back onto the carriage.
The door moves a few inches then reverses: The opener’s force settings may need adjustment, or the springs are broken and the opener can’t lift the full weight. A door that opens 6 inches and stops is almost always a broken spring.
Step 3: Use the Emergency Release (If You Need to Get Out)
Every garage door opener has a red emergency release cord hanging from the trolley on the rail. Pulling this disconnects the door from the opener so you can operate it manually.
How to use it safely:
- Make sure the door is fully closed before pulling the cord. If the door is partially open and the springs are broken, releasing the trolley could cause the door to crash down.
- Pull the red cord down and toward the opener (away from the door).
- Lift the door manually. If it feels normal (10-15 lbs), the problem is with the opener, not the door. If it’s extremely heavy (100+ lbs), you have a spring issue — stop and call for help.
- Prop the door open with a sturdy object if you need to drive out.
Important: Once you’ve used the emergency release, the door is fully manual. Don’t leave it open and unattended — anyone can lift it from outside.
Step 4: Identify the Problem
Based on what you’ve found, here’s what you’re likely dealing with:
Problems You Can Fix Yourself
- Dead remote battery — swap it out
- Tripped breaker or GFCI — reset it
- Unplugged opener — plug it back in
- Blocked photo-eye sensors — clear the obstruction and clean the lenses
- Disengaged trolley — re-engage it
- Engaged manual lock — disengage it
Problems That Need a Professional
- Broken spring — the door feels impossibly heavy when lifted manually. Do not attempt to open or repair. Call for spring replacement.
- Broken cable — you see a loose cable hanging or coiled on the floor. The door may be crooked. Do not operate. Call for cable repair.
- Door off track — the door is visibly crooked or jammed at an angle. Forcing it will cause more damage. Call for off-track repair.
- Stripped opener gears — the motor runs but the door doesn’t move even when connected. The internal gears are worn out. Call for opener repair or replacement.
- Damaged panels — a panel is cracked, bent, or caved in (from a car bump or storm damage). Call for panel replacement.
What NOT to Do
Don’t force the door. If it’s stuck, there’s a reason. Forcing it — whether with the opener or by hand — can bend tracks, snap cables, or worsen whatever’s already wrong.
Don’t try to repair springs yourself. I can’t stress this enough. Torsion springs store enough energy to cause serious injury. This is the one garage door repair that should never be DIY.
Don’t disconnect the opener with the door open if springs are broken. The door will come crashing down with nothing to hold it.
Don’t keep hitting the button. If the opener tried and failed, hammering the remote button won’t help. You’re just grinding gears and burning out the motor.
Don’t ignore it. A door problem that’s minor today becomes a major repair next week. Bent tracks, fraying cables, and weakening springs all get worse with continued use.
When to Call for Emergency Service
Call right away if:
- Your car is trapped and you can’t operate the door manually
- The door is stuck open and you can’t secure your home
- A cable snapped or the door is visibly hanging at an angle
- You smell burning from the opener motor
- Anyone was near the door when it failed and something fell or shifted
