Why won't my garage door open all the way?

A door that stops partway is telling you something is either stopping it or no longer helping it. The opener only steers the door; the springs carry the weight. So the first question is always the same: is the opener quitting on purpose, or is the door too heavy or stuck for it to keep going? A few quick checks answer that before you ever pick up a tool.

First: how far does it go, and what does it sound like?

Watch one full attempt. If the door rises a few inches and stops while the motor strains or hums, something is holding it down or it has become very heavy. If it rises smoothly to a point, stops, and the motor shuts off quietly, the opener is stopping on purpose, which points to a setting. That one observation sorts most cases.

Check for ice and a stuck bottom seal

In cold weather, water under the bottom seal can refreeze and glue the rubber to the slab. The door lifts an inch or two, then the opener gives up. Look along the bottom edge for ice and break it loose gently by hand rather than holding the button. We cover this in garage door frozen to the ground.

The open-limit setting

Openers have a travel limit that tells them where "open" is. If that limit gets knocked out of position, the opener stops the door early even though the door could go higher. On most openers it's a small adjustment, and your opener's manual shows which control moves it. Make small changes and test after each one. If you're not sure which control does what, leave it and have it checked, because a limit set wrong in the other direction can strain the door.

A weak or broken spring makes the door heavy

This is the cause to take seriously. When a spring weakens or breaks, the door gets heavy, and the opener may lift it a little and then stall. Disconnect the opener using the red release handle with the door closed, then try lifting the door by hand. A balanced door feels light and stays where you leave it. If it's heavy, or it drops when you let go, the springs aren't doing their job. Our guide to testing garage door balance walks through it, and the signs of a broken spring shows what to look for. Don't try to adjust or replace springs yourself; they hold a lot of stored force.

Something binding in the track

A roller that's jammed, a bent section of track, or a hinge that's seized can catch the door partway up. Look at the tracks on both sides with the door closed: they should be straight, clear of debris, and evenly spaced from the door. A roller that has popped out or a door hanging crooked is off-track; stop using the opener and read off-track garage door safety. If everything looks clear, a light spray of WD-40 on the hinges and roller stems often frees a sticky spot.

Remote and sensors usually aren't the cause

Safety sensors stop a door from closing, not from opening, so a door that won't rise is rarely a sensor issue. If the wall button works but the remote doesn't, that's a different problem; see opener troubleshooting.

When to call

If the door is heavy by hand, you heard a bang, a cable looks loose, or the door is crooked, stop and have it looked at. If it's just a limit setting or a bit of ice, you can likely sort it yourself.
