Why is my garage door opener not working?

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.

Common reasons a garage door opener is not working

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

• Nothing at all, no hum, no light. That is a power problem. The unit is unplugged, the outlet is dead, or a breaker tripped.
• The wall button works but the remote does not. The opener and door are fine. The issue is the remote battery, the keypad, or a lock setting.
• The motor hums but the door does not move. The drive gear may be stripped, or the trolley is disconnected from the rail.
• The door starts, then reverses or stops. That is almost always the safety sensors or a travel-limit setting, not the motor.

Sorting your problem into one of these buckets saves you from chasing the wrong fix.

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:

1. 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.
2. Swap the remote battery. If the wall button works and the remote does not, a fresh battery fixes it most of the time.
3. 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.
4. 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.
5. 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.
