Why is my garage door opener not working?

Short answer

When your garage door opener is not working, the cause is usually one of a few things: dead power or a dead remote battery, safety sensors knocked out of alignment, travel limits that drifted, or a worn gear or board inside the motor. Most of these you can check in a couple of minutes. The deeper electrical and gear faults need a tech. Start with the simple checks below before you assume the worst.

That is the short version. Which fix you need depends on what the opener does (or does not do) when you press the button, so start there.

Which fix matches your opener's symptom

Watch and listen to the opener when you hit the button. The behavior points to the cause:

What the opener does	Most likely cause	First thing to try
Nothing at all, no hum, no light	No power reaching the unit	Check the plug, the outlet, and the breaker
Wall button works, remote does not	Remote battery or a lock setting	Swap the battery, then check the wall panel lock
Motor hums, door does not move	Stripped drive gear or a released trolley	Check the red release cord and the trolley
Door starts, then reverses	Photo eye sensors or travel limits	Clean and realign the sensors
Door opens but will not close	Blocked or misaligned sensors	Check both sensor lights for a steady glow
Clicks once, then silence	Failing capacitor or a seized motor	Stop trying it, this one needs a tech
Forgets settings after every outage	Failing logic board	Book a tech, this is not a DIY fix
Runs, but the door only moves partway	Travel limits have drifted	Adjust the limits, or have them reset

Sorting your problem into one of these buckets saves you from chasing the wrong fix. If nothing on the list matches, or the opener behaves differently every time you press the button, it is worth a step back to reset the opener before you replace any part.

Quick checks you can do yourself

Run through these in order. None of them put you near a spring or cable, so they are safe to try:

Check the power. Make sure the opener is plugged in, the outlet has power, and no breaker tripped. A vacuum or ladder bumping the plug is a common culprit.
Swap the remote battery. If the wall button works and the remote does not, a fresh battery fixes it most of the time.
Look for lock or vacation mode. Many wall consoles have a lock button that disables the remotes on purpose. Press and hold it to toggle it off.
Wipe and aim the sensors. The two photo-eyes near the floor must see each other. Clean the lenses and line them up until both indicator lights glow steady. If one is blinking instead of steady, see what a blinking sensor light is telling you, or follow the steps to line the photo eyes back up.
Check the trolley. If someone pulled the red release cord, the door is disconnected from the motor. Re-engage it by pulling the cord toward the door or running the opener.

If one of these brings the opener back, you are done. Our guide to why a garage door opener stops working walks through these same steps in more detail.

When the opener problem is not DIY

Some opener faults are internal and need a tech with the right parts:

Stripped drive gear. If the motor runs but the door will not move and the trolley is engaged, the plastic gear inside the head is likely stripped. It is a common, fixable repair.
Failed logic board. An opener that forgets its settings after every power outage, behaves randomly, or will not respond consistently often has a dying control board.
Worn limit or force settings that will not hold. If the door reverses or stops short even after you adjust the limits, the module may be failing.
Burned-out motor. An old unit that hums, struggles, and finally quits has usually reached the end of its life.

These are bench-and-board repairs, not driveway tinkering. A tech can tell you on site whether a board or gear swap is worth it or whether a new opener is the better value. For doors that fail entirely and trap a car inside, our garage door repair across Denver covers same-day diagnosis.

Repair the opener or replace it?

A dead remote, a dusty sensor, or a stripped gear is usually a quick repair, not a reason to replace the whole unit. Replacement makes more sense when the opener is more than 10 to 15 years old, runs loud and unreliable, lacks the photo-eye safety sensors required since the early 1990s, or would cost nearly as much to fix as to replace. Newer openers are quieter, safer, and add battery backup and app control that older units cannot match.

If you are weighing the two, knowing the typical cost of garage door opener repair against a new install helps you make the call with real numbers instead of a guess. Our full breakdown of when to repair or replace your opener walks through the age, cost, and safety cutoffs in one place.

Getting your opener fixed

If the simple checks did not bring your opener back, the fix is usually a sensor, a gear, or a board, and that is a same-day visit for us across Lakewood and the Denver metro. We offer free estimates, flat-rate pricing, and veteran, senior, and first-responder discounts. To book a tech, see our garage door services and tell us what the opener is doing when you press the button.

Most openers that quit are back in service the same day, because the parts that fail most often are the ones our trucks carry.
