The call is made. Somebody is on the way, sometime in a window that feels longer than it is, and the door is sitting where it stopped: two feet open, or all the way up with a spring in two pieces above it, or shut with the car on the wrong side. There is nothing to do but look at it.

That waiting period is where a surprising amount of the extra damage happens. Not in the failure itself, which is usually one part, but in the three hours afterwards, when everyone in the house tries the button once more to see if it has sorted itself out.

Most of the second failure happens after the phone call

A garage door that has stopped working has usually stopped for a reason that makes further attempts expensive. With a broken spring, every press asks the opener, the cables and the drums to lift a door that now weighs what it actually weighs, a load none of them are built for. With a door out of its track, every press drives the rollers harder into the wrong place. The first failure was a part. The second one, if it comes, is the part plus whatever the opener tore trying to help.

So the most useful thing you can do while you wait is make sure nothing moves the door at all, and that includes things nobody in the house is touching.

Unplug the opener, not just the habit

Telling the family not to press the button covers the wall button. It does not cover the remote in the other car, the keypad outside, a phone app, or a timer-to-close setting that will cheerfully try to shut the door at nine tonight because that is what it does every night. Pull the opener's plug out of the ceiling outlet. It is the only instruction that reaches all of them at once, with one catch in the next paragraph.

If the opener has a battery backup, unplugging it will set it beeping every couple of seconds, and it will keep working on the battery. Disconnect the battery under the light cover too. That also ends the beeping.

Leave the red cord alone unless the door is fully down

The release cord disconnects the door from the opener so it can be moved by hand. On a balanced door that is exactly what it is for. On a door that has stopped part-way because a spring or cable has failed, the opener's carriage may be the only thing holding it up, and pulling the cord hands the whole weight to gravity.

If the door is closed and the springs look whole, the cord is safe and you can lift the door by hand to get the car out. If the door is anywhere else, or you are not sure, leave it connected and leave it where it is.

If it is stuck open

This is the version that is genuinely urgent, because the house is open, and it is worth saying so when you call. While you wait:

  • Lock the door from the garage into the house. That is the security boundary that matters tonight, not the big one.
  • Move anything worth stealing out of sight, and anything worth crushing out from under the door.
  • If the door is fully open and still, a pair of locking pliers clamped onto each track just below the bottom roller stops it from coming down on its own. Clamp, do not climb.
  • Do not try to pull it down by hand. A door with a broken spring does not come down gently, and it does not go back up at all.

If it is stuck closed with the car inside

This one is an inconvenience rather than an emergency, and it helps to treat it that way. Do not try to squeeze a car out under a door that is part-open, and do not wedge it higher with a piece of timber. Get a lift to work. A door that is shut is a door that is not getting worse.

It is also worth telling whoever answers the phone that the car is stuck but the house is secure. It helps them decide who needs someone first, and the next time your door is the open one, somebody will have done the same for you.

Send the photographs that save a second trip

The most expensive part of many repairs is the visit where the right part was not on the truck. A few photographs, taken from a safe distance and sent before the technician sets off, fix most of that:

  • The spring or springs above the door, close enough to see whether there is a gap in the coil.
  • Both bottom corners of the door, where the cables attach.
  • The whole door from the driveway, so anyone can see whether it is sitting level.
  • Any label on the door or the opener head, for the make and model.
  • A sentence on what happened: a bang, a grinding noise, a door that stopped and reversed, or nothing at all.

Three things worth checking before anyone arrives

Not every door that stops is broken. It is worth two minutes to rule out the three free causes, without moving the door:

  • Is the opener's carriage disconnected from the door? A cord pulled by accident makes the motor run and the door stay still.
  • Are both photo eye lights at the bottom of the tracks steady? A blinking or dark one means the door will not close by remote, and a wiped lens or a nudged bracket is the whole repair.
  • Is the wall control in lock mode? A lock light on the wall button makes every remote in the house go quiet.

If it turns out to be one of those, call back and cancel. We mean that. We would rather lose the visit than turn up to press a button.

The useful thing to do is very little

Unplug it and disconnect its battery, leave the cord alone, lock the house door, take the photographs, and wait. Almost everything that turns a spring job into a spring, cable and opener job happens because somebody could not bear to leave the door alone for an afternoon.

It is the least satisfying advice we give. It also saves more money than anything else we say on the phone.
