The problem is that one of the garage doors "catches" (i.e. stops) while going up at about 2 feet off the ground ~90% of the time. When the button is pressed again, it goes all the way down. This cycle can be repeated ad nauseum, or I can give the door a gentle tug upward just before the "Sticking" point, and this will give the door enough "impetus" to make it all the way up. http://m.youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c
After removing the old batteries, make sure the plus and minus signs line up with the plus and minus signs on the inside of the transmitter. Otherwise, the new battery won’t work in the transmitter, and it could give you a false sign that something else may be wrong. Once the battery is in place, test the transmitter, and if it works, replace the transmitter door.

Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal door track. Extension springs represent a hazard to bystanders when a spring, pulley, or cable breaks under tension. Metal parts from extension spring systems can suddenly be launched.

Squealing, screeching, or grinding noises from your garage door are usually indicative of a lack of lubricant or an accumulation of dirt or debris in the tracks. When removing debris, do not use harsh chemicals to clean the tracks. Once the track is clean, coat it with lubricant designed especially for garage doors, if possible. If you do not have access to this special type of lubricant, you can use WD-40 on the tracks and hardware.

Once the springs break, quite a bit of tension is put on the door cables, and they will often break next. When these cables break, they will snap and forcibly fly out like a broken rubber band. Think about how much it hurts to be snapped by a broken rubber band, and then multiply it by a hundred to account for the size and weight of the garage door cables. https://www.youtube.com/e/Z_eZc-kh40c


Though you can do some maintenance to your garage doors on your own, it may be a good idea to schedule routine inspections with a professional. A typical service call will include a manual inspection of the door and opener. Then adjustments can be made including spring tension, chain/belt tension, limits and force adjustments and door lubrication. Fees for this service vary from place to place, but garage door repairs typically cost between $147 and $340.
A garage door with a broken torsion spring can fall rapidly and cause injury or death. However, the most common danger comes when your torsion springs break and you decide to undertake the repair/replace them yourself. Torsion springs can be very dangerous, and you not only need the exact tools for the job, but also need to have a good knowledge of the mechanics involved. Some of the parts involved in such a process can be life threatening, and must be handled with care and precision, which is why it is always recommended that you call in a professional, rather than trying to handle a replacement or repair by yourself. Failure to do so may leave you with injuries and/or damage to your property.
10.4 Raise the second bar 90 degrees and insert the first bar. This is "three." Continue winding. If the spring shortens in length, unwind the spring and switch sides - the springs are on backward. Otherwise, continue winding until you reach a count of "30." This is 7 1/2 turns, which is normal for most 7' doors. Longer life springs are wound the same number of turns. Newer steel doors with only one strut on top often need only 7 1/4 turns. On 8' doors count to 34. Each time you insert a bar into the winding cone, listen for the click to let you know the bar is in all the way. Not inserting the bar all the way could cause the cone to explode.

Replacement spring procedure took me exactly 1 hours including preparation and clean-up for double aluminum garage door. Watch the DIY video on Youtube, save $$, be careful with winding the torsion springs. Rule of thumb: 7' height door garage= 7' x 4 (each 1/4 turn) + 1 = 29 turns (1/4 turn), 8' height door garage = 8' x 4 + 1 = 33 turns (1/4 turn), and so on....

When you're done watching this video you'll know how to determine whether the company you hired to replace your garage door spring installed the right size spring on your door. You'll also learn the consequences to your garage door opener if the wrong size spring is used. If you are having a problem with your garage door spring, the 2:30 minutes you spend watching this video is time will spent.


When you install a new garage door, replace all the hardware as well. If your automatic opener doesn’t have an automatic reversing system that includes photoelectric eyes, replace it. Doors with openers also require two extra pieces of hardware that you’ll see in Photo 4: a support strut (usually included in the door kit) and an opener bracket (not included). For doors with torsion springs located over the door, spend the $50 or so to have a garage door professional release the tension.
10.1 It is now time to wind the new springs, but before doing so, I recommend marking the shaft just beyond the winding cone. This is a final step taken to assure that you have installed the springs on the correct sides of the center bracket. Torsion springs always grow in length when they are wound in the proper direction. If your spring does not get longer as you wind it, you are winding it the wrong direction probably because it is improperly installed. We recurrently get calls about springs coming loose from the cones at about 6 turns. If this happens, switch the springs.
7.2 If the spring bracket is slotted, vise grip the bracket to secure the shaft in the bracket. This will keep the shaft from possibly falling out and causing injury or damaging the garage door or shaft. You can also secure the shaft with a cable tie. Remove the bushing from the cone and leave it on the shaft next to the center spring bracket. Often the bushing gets stuck in the cone and customers will call us about getting a new bushing until they discover it is still in the cone of the spring replaced earlier. http://www.youtube.com/v/Z_eZc-kh40c&feature=youtu.be

Sometimes, people unplug their power source and then wonder why their garage door opener fails to work. Sounds ridiculous, I know, but it does happen. Make sure that your garage door opener is plugged into a working outlet. Outlets sometimes go out without warning, so you can check to see if the outlet is working by plugging another working electronic device into it. Also, check your circuit breaker, fuse, or GFCI.

If you have a garage door opener and you suspect a spring has broken, do not disconnect the opener from the door (by pulling the red emergency release handle) while the door is open. If you do, the door can come crashing down under its nearly full weight, with nothing to stop it. This is an extremely dangerous situation. It is never safe to leave the door open when a spring has broken because someone might try to close the door without realizing how heavy it is. Or, they might pull the emergency release handle on the opener.

If the door only goes up six inches and stops, or moves very slowly when using your remote, you could have a broken spring as well. Some customers will notice that the top section of their door is bent or that the door falls very quickly when lowering. Your door may be “crooked” or jerky when going up and down, and both of these signs indicate your torsion spring is in poor condition and very likely to break in the near future. Any time you hear a loud “popping” noise while operating, you should inspect your torsion spring immediately for signs of damage.

Check your garage door rollers to see if they have come off their tracks. If no damage has been done, a tech should be able to easily place them back on. If the track has become bent, however, it must be repaired and possibly (depending on the amount of damage) replaced. Don’t operate your door if it's off track or your track is bent. Your door could become seriously damaged.

You may remember a time as a kid when you and your siblings would close the garage door and run underneath it as fast as possible to make it out before the door closed. Well, on any garage door installed after 1993, that’s no longer possible thanks to two tiny photo eyes on either side of the garage entrance. These photo eyes transmit an invisible beam between each other that detects if anything is in the garage door’s path when it closes. This safety measure is there to prevent automatic garage doors from closing on top of someone or something and causing serious injury or damage to property.

Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break. https://youtu.be/Z_eZc-kh40c
