Why garage door stops after a few feet you replaced a worn out sproket assembly unit any ideas?
The door opener has stops on it. Remove the chain from the sprocket and run the opener to the door closed position until it stops (unattached to the opening assembly. Then put the chain on with the door opener with the door closed. Put the chain on where it would be with the door in the closed position. Re-hook the chain opening assembly and the door should open. Adjust the open position (small adjustments) using a flat screwdriver in the slots on the side of the garage door opener. Good Luck.
How can you adjust your garage door so it will clear the opening when it is up?
If you have a chain drive garage door, there may be an Up Limit Cam Roller attached to a chain link assembly between the Door Opener unit and the Trolley where the release arm is attached. Loosen the Up Limit Cam Roller and move it a few chain links away from the Door Opener unit & toward the Trolley assembly. This should allow the garage door to open farther. Move as required to have the garage door fully clear the garage opening. The Up Limit Cam Roller assembly is what appears to stop the chain travel when it comes in contact with the Idler Sprocket at the Door Opener unit. I was the one who asked this question, but was able to figure it out after further review of my limited garage door opener instructions. I was having problems with the rear lift gate on my car hitting the garage door. This solved the problem.
How do you close garage door when chain breaks?
Replacing the chain is not for the novice since it can be dangerous. It is better to call a garage door company to get it done - they may also repair what it is that caused the chain to come off track.
How To Perform Routine Maintenance To Your Garage Door Opener?
Performing proper maintenance on your garage door opener is important to the safety and security of your and your family. To conduct tests and maintenance you will need a flat head screwdriver, a ladder, a light penetrating oil such as WD-40 and a piece of scrap wood. Before beginning your maintenance and inspection of your garage door opener, disconnect the power to the door. Never wear loose fitting clothing or jewelry that can get caught in the garage door mechanisms while inspecting them. Clean and Lubricate The Garage Door Periodically you will need to clear debris, such as dir, leaves and dead insects from the metal parts of the garage door opener with a soft brush. Using your light penetrating oil, lubricate the rive chain of the garage door opener. Adjust The Garage Door Chain When inspecting the chain tension on the garage door, measure to make sure that their is not more than a %C2%BD” sag below the rail. If there is more than a %C2%BD” sag in the chain’s tension and it is not corrected, the chain will bang against the rail and cause premature wear to the drive sprocket. You will need to tighten the chain using your flat head screwdriver until it is within the %C2%BD” range. Do not over tighten the chain. Perform Minor Adjustments to the Door When performing your maintenance inspection to the garage door opener, inspect that springs and cables are not stretched out of shape. This can cause the door to be unbalanced. You may have to tighten limit screws used on the garaged door opener if your door doesn’t open or close completely. One of the most important inspections you will want to perform is to test that your safety sensor is not out of alignment. You can do this by placing your piece of scrap wood under the door against the side of the door opening. If your door is out of alignment, you will want to make adjustments to the sensor right away. For the safety of your and your family, make it a common practice when performing maintenance and safety inspections on your garage door opener. This can save you from devastating consequences in the future.
Which garage door opener should you purchase?
There is an article about garage door openers on my garage door blog. It deals with the different types of garage door openers and what their applications may be. This may be a good starting point for you. I can't post a link here, but I can tell you that there are a few basic types of garage door openers. Chain driven openers, belt driven openers, screw drive openers, and jackshaft openers. The chain drive opener is a very affordable, sturdy opener good for most garage door applications. The belt drive opener is more expensive than the chain drive opener, but it is much quieter than any other opener type. The screwdrive opener is very common, easy to get from home improvement stores, and is generally pretty cheap and easy to install, but it has problems operating when the weather gets cold because the lubricant around the screw assembly thickens causing the door to not operate. The jack shaft opener is a new opener in the industry and is able to be wall mounted instead of on the ceiling. It is good for folks who have ductwork or pipes in the way or other clearance issues that would otherwise prevent one from being able to have a garage door opener at all. These jackshafts are nice, but they are quite expensive. Hope this helps. If I need to expand on anything or clarify, just let me know.
How does a garage door opener work?
A garage door opener works by using a small, electric motor to lift a rolling door assembly. The motor uses a chain or series of gears to control the opening and closing of the door.
How to install a garage door opener?
A garage door opener has become an indispensable appliance that is normally found in every modern home. Not only does it add convenience to the house, but most garage door openers have a security component that helps make the home more safe. For those homeowners who do not have a garage door opener, it is a relatively easy installation for a homeowner with even a modicum of mechanical ability. The first step in installing a garage door opener is deciding which type of garage door opener is right for the homeowner’s needs. Once that decision has been made and the garage door opener has been purchased, the next step is to open the garage door opener and check to make sure the garage door opener is complete. The next step is for the installer to gather any tools that will be needed for the installation. Typically, a Phillips head screwdriver, a flat-head screwdriver, a drill, a hammer, a ruler, and a leveler. Most garage door openers require that the first step in installing the garage door opener is assembling the rail. Once the rail has been assembled, the next step is inserting it into the power source. The slider/traveler unit must then be connected to the rail, and then the idler pulley must be affixed to the opposite side of the rail. The chain must now be attached to the traveler. Once the chain is attached to the traveler, the chain is then snaked around the drive wheels of the power unit and looped around the idler pulley back to the traveler. The chain ends are then attached with a retaining clip. The header must then be mounted at the height recommended by the manufacturer, and then attached to the idler assembly. The final step for attaching the garage door assembly is to attach the power unit to the garage ceiling joists. It is now time to make sure the door clears the manual unit. This is usually done by manually lifting the door to ensure it is able to clear the power unit. If it does not clear, the assembly must be adjusted. If it does clear the assembly, the sensors can then be installed. Once the sensors have been installed, it is time to test the door. Once the door has been successfully operated, the installation is complete.

How to Repair a Garage Door Opener?
Garage doors that open automatically are one of those conveniences we take for granted. When a garage door opener suddenly stops working, it can be extremely annoying. Here is a step by step guide to fixing your garage door opener. First, you should check to see if the cord that feeds power to your garage door opener is actually plugged into an outlet. This may seem too obvious, but this is a common reason why garage door openers do not work. If that doesn’t fix the problem, check your owner’s manual for some kind of lock feature. Someone may have inadvertently activated the lock feature, and that feature may be preventing the door from operating. The manual should tell you how to turn the lock feature off. If that doesn’t work, try unplugging the garage door opener and then plugging it back into an outlet a few times. This may reset the censors, allowing the opener to work again. If that doesn’t work, you should perhaps check to see if the batteries in your remote control for the garage door opener haven’t run out of power. If it still doesn’t work with new batteries, it is possible you accidently deprogrammed the remote control. Check the owner’s manual to learn how to reprogram it. If that didn’t fix the problem, check to see if the beam censor for your garage door opener is plugged in correctly. Next, try cleaning the censor itself. Its possible dirt, grime, or dust may have built up on the censor, preventing it from sending the signal to activate the garage door’s motor. Lastly, you should check to see if the chain that lifts up the door has been broken or become loose. If so, it is unfortunately not safe for you to try to repair it on your own. You should call an electrician who specializes in garage door repair. Until the repair man arrives, you are going to have to manually open the garage door yourself by either using a release cord or a handle. With these simple steps you can easily trouble shoot most problems that prevent a garage door opener from operating yourself.
