There are few things more annoying than a garage door that just refuses to budge. You are rushing out, you hit the button, and nothing happens. The good news is that a garage door opener that won’t open or close usually has a simple, findable cause.
Let us get right to it. When a garage door opener won’t open or close, run four checks. Power, the safety sensors, the remote, and then the door’s balance.
Start with the easy stuff and work up. Most cases come down to lost power, blocked sensors, dead batteries, or limit settings. The rest of this guide shows you each check in order.
One quick test tells you a lot. It separates an opener problem from a door problem, and we cover it below.
First, Run the Balance Test
This single step saves a lot of guessing. It tells you if the fault is the opener or the door itself.
Pull the red emergency release cord to disconnect the opener. Now lift the door by hand, slowly. If it glides up and stays put, the opener is the issue.
If the door feels heavy, sticks, or slams down, the problem is the door. That usually means a spring, cable, or track, not the opener. Reconnect the cord when you are done.
Check 1: Power and Lock Mode
Power is the top cause of an opener not responding at all. A dead unit has often just lost its supply.
Confirm it is plugged in, since vibration can loosen the plug over time. Check the breaker and GFCI outlet for a trip. Try a lamp in the same outlet to be sure.
Now check the wall console for lock or vacation mode. If it is on, the remotes are blocked. Hold the lock button for a few seconds to switch it off.
Check 2: Safety Sensors
If the door opens but won’t close, suspect the sensors first. They are the most common cause by far.
The two sensors near the floor must line up and stay clean. Dirt, webs, or a bump breaks the beam. Wipe the lenses and adjust them until both lights stay solid.
A blinking sensor light points to misalignment or a blockage. Our sensor repair page covers the full fix.
Check 3: Remote and Intermittent Range
The wall button works, but the remote does not? Start with a fresh battery. Weak batteries are the usual cause.
Sometimes the remote only works up close. This intermittent range often means a weak battery or signal interference. LED bulbs and routers near the opener can scramble the signal.
If a new battery and a clear range do not help, reprogram the remote. Use the Learn button on the motor unit to re-sync it.
Check 4: Travel and Force Settings
When the door stops short or reverses on its own, the settings may have drifted. Travel limits tell the motor how far to move.
If the down limit is off, the door bounces back up before it closes. A force adjustment is sometimes needed when the door reverses for no clear reason. The motor thinks it hit something and backs off.
These dials sit inside the motor head. Setting them wrong is unsafe, so this is a good point to call a pro.

When the Motor Runs but the Door Will Not Move
Sometimes you hear the motor, but nothing moves. Two things usually cause this.
First, the emergency release cord may still be disconnected. Reconnect it to the trolley and test again. Second, the main drive gear can strip on older units.
If the trolley moves but the door does not, a carriage part has failed. Both are real repairs, not quick fixes. Forcing the door makes it worse.

Frequently Asked Questions
Why won’t my garage door open or close at all?
Start with power. Check the plug, breaker, and GFCI outlet, and make sure lock mode is off on the wall console.
Why does my garage door open but not close?
This is almost always the safety sensors. Clean the lenses and line them up until both indicator lights stay solid.
How do I know if it is the opener or the door?
Pull the release cord and lift the door by hand. If it glides smoothly, the opener is the issue. If it feels heavy, the door is.
Why does my garage door reverse before it closes?
Misaligned sensors are the top cause. If those are clean, the down travel limit or force setting likely needs a small adjustment.
My remote only works up close. Why?
This intermittent range usually means a weak battery or signal interference. Replace the battery and move the LED bulbs or routers away.
The motor runs, but the door does not move. What now?
The release cord may be disconnected, or the drive gear may be stripped. Reconnect the cord first, then call a pro if it continues.
Is it safe to force a stuck garage door open?
No. Forcing it can damage the opener or hurt you, especially with a broken spring. Use the manual release and call a pro.
