The most common garage door opener parts that will wear out and need to be replaced out are:

• drums

• cables

• pulleys

• springs (whether they are torsion or extension)

• hinges

• the actual motor

These are the parts on your garage door that receive the most wear and therefore these are the parts that will give out the quickest.

Its wise for a homeowner to do a quick visual inspection of these the parts just mentioned at least once a year.  It really should not take more than 10-15 minutes.

Nevertheless, if they do break down and your should need to replace one of your garage door parts here the the process you should use.

1. Find out which brand and model your garage door is.
2. Evaluate exactly what is causing the problem and if possible write down the model number of that particular garage door part.
3. Call a local garage door dealer in your area and ask if they stock this part.  If they do ask them what it costs.  You might also want to ask how much it would cost to have it installed.  Do not purchase the part just yet.
4. Go to the internet and check out several online garage door opener parts stores and check out their prices.
5. If you can get that particular part significantly cheaper online and can install it yourself then by all means purchase it.
6. If the price is not much cheaper (remember to factor in shipping though garage door parts stores on the internet offer free shipping over a certain dollar amount) or if you cannot install it yourself go to the local dealer.  Just make certain they guarantee their work.  About half of the parts that malfunction on your garage door will be easily fixed with the proper part.  The other half will require the skills and special tools of a garage technician to be done properly.

When you are choosing a garage door company make sure you choose one who has a good reputation in your area, has experience in what they do, recommended by at least three people, and offer some kind of warranty on their work.

Here is some weather stripping advice. A common part for any garage door is the threshold.  The long plastic strip is crucial to any garage door set up in any neighborhood in any city.  I have noticed that many people do not have them.  I did not have one until my best friend pointed it out to me the other day.  I was surprised!  Here I have a website that deals with this subject and I do not own a garage door threshold.  They are very important it turns out.  They help keeping out rain, leaves, and snow from inside your garage.  Without it the inside will get littered over time with tons of debris.  They can also keep out rodents as when the door presses down on the weatherstripping it should make an almost air tight seal.

As far as they go it is important to find and purchase the most durable garage door thresholds you can find on the web.  The best ones are made from vinyl and if quality engineered should provide a long lasting barrier between your garage door bottom and the floor.

When you buy a threshold please make certain that you buy extra glue.  I have spoken with several people who have installed them at their houses and they mentioned that there was not enough glue that came with the threshold to install it properly.  Order extra glue when you purchase it or go to the store and get extra.  Also before you apply the glue you want to clean the area underneath before you apply it.  Other than that the instructions are fairly straightforward on most products.

I had a friend by the way that lives in Portland where it can rain a lot.  He always had a problem with water getting into his garage.  He had tried a few items like garage door seals and door adjustments but they did not work too well.  After he installed a threshold he did not have the water problem any longer.  Definitely a good buy.

Another common replacement part, especially for old or worn garage doors, are spring mechanisms.  There are two types.  It will call for a  torsion spring that is mounted on the front wall of the garage just over the door.  Please, and I want to emphasis this, make sure you get professional to relieve the tension before removing the spring to replace it.  Torsion springs can be potentially dangerous and can cause serious injuries if improperly dismantled.

If you have two springs that are mounted over the tracks, they are extension springs, which can be removed safely by just about anyone if they know what they are doing.  All you have to do is measure the length and width of your old door to determine the size of the door you require.  Then measure the area between the top of the door jamb and the ceiling to determine if you have sufficient space for the door you want. Standard 7′-high doors require 10″-12″ of headroom. However, many door manufacturers sell low-headroom kits that allow their doors to operate with as little as 4 1/2″ of headroom. Additional headroom is needed for attachment of an automatic garage door opener

Track hangers are items that will not go out often. The only way that you will usually need to replace them if someone is hanging on your garage door and puts an excessive amount of stress and weight on them to bend them or your track hangers are just very old and have become flimsy.  Honestly its going to be hard to find a complete track hanger online.  You can find tons of components to build one if you really know what you are doing.  Like you can just buy the track.  There are two types: standard and low headroom.  You have the vertical track on both sides of the opening.  The horizontal track is attached to the ceiling.  You would have to measure it to see exactly what you need.  I would just pay someone to come and install it for you if you want to replace this peice though.  Its a lot of work if you do not have the proper tools to do it.

The cable drum can be an item that many people have to replace during the life of their garage.  Basically they are the grooved drums on the torsion spring shaft that lifting cables go or wind around when door is opening and closing.  They can experience a lot of wear depending on who heavy the door is.  What you will probably end up replacing more than anything else is the extension spring cable.  That’s the component that usually wears out.There are many brands out there.  Make sure that the cable is aircraft grade high quality cable.  Many people recommend changing your cables if you ever have to  replace any broken springs on the drum.  Stress caused by a broken spring can transfer undue stress to an already worn out cable and cause it to break which will cause your door to fall off the track.

And a last common item that some people will have to replace most likely do to a baseball or accident is the window lite.  This is the glazed section with various types of glass or clear acrylic to allow for light and visibility.  They can be found on almost any site and in various different forms.

I really hoped that this helped.  If anyone has any questions, comments, or advice about garage door opener parts please let me know.  Use the comment section.  I am always looking for new items or suggestions.  In different parts of the country I am willing to bet that people are coming across different problems and I am interested in knowing what they are.  I have received some excellent feedback so far about this site.   So if you write a comment let me know what state you are from.  I have a friend who works for Overhead so this week I am going to ask him what are some of the top five main problems that people call in for and then post them so that people can a) prevent these things and b) know what to do if these things should happen.  Thanks and take care.
